The possible disturbances of the crystalline gratln~,; of cubical zinc selenidav4em analysed, and the disturbances which could form luminescent centr9s In- Ve3ti-ated. 10 samples of zinc selenide were prepared at temperatures varying from 120 - 8500c, and the luminescence under the influence of ca'u-hode rays do- termined. This luminescence ranges from the yellow to the infra-red region. The authors calculated that the vacancies in selenium are the most 112kely lumines- cent centres in'the cubical crystalline grating of zinc selenid-1. Active impurities which could cause the lurhinescence of zinc selenid-9 were also investigated.

Riehl and Ortmann (Refs. 11 and 13) proved that some metallic ions function as stabilisers of disturbances. During Investigations of the luminescence of ZnO and ZnS it was shown that the luminescent centres are vacancies of oxy6en or sulphur, and that metallic impurities stabilise to a larger or lesser degree tl,'Ie aforementioned disturbances in the crystalline Fratirr,. By applyinG this idea to the lumine.3cence of ZnSe it can be stated that the lumin- escence of zinc selenid? is due to the vacancies in selenium, and that these are stabilised by various card 2/3 metallic impurities.

So far, the reactions during the formation of copper tungstate from metallic oxides have been studied and the diffusion processes at the contact between copper oxide and tungisten oxide (Rlaf.4; Tamman, G., Westerhold, F., Z.anorg.allg. Chem,35 (1925),149). Recently, the equilibrium between copper tungistate and hycLrogen as well as the thermodynamic properties of copper tungstate Jaave been studied (Ref.5). The electrical properties of sintered samples of copper tungstate were studied by the authors. The samples were prepared from sodium tungstate (Merck) and copper nitrate. From these, tungsten oxide and copper oxide were prepared. These were mixed and heat-treated at 800*C for 48 hours in oxygen. Samples 1 and 2 were prepared by this method while anot'her two samples (3 and 4) were prepared by mixing the oxides into molten sodium chloride. The malt was held at Carct 1/ 5 23070 Z/037/61/000/002/002/003 The Semiconducting Properties E133/E435 8200C for 48 hourm. After cooling, the powdered preparation was extracted in hot distilled water and washed in water several times. The samples were pressed at 15000 kg/,cm2 into cylindrical shape and heated in a quartz tube to 5800C for 4 hours in oxygen. After slow cooling, gold contacts were evaporated onto the samples. These electrodes proved ohmic between 0 and I Volt. The measurements on all samples gave identical and reproducible results-. The conductivity a of the samples was measured at a constant oxygen pressure of 750 mm Hg in the temperature range from 273 to 8730K. Fig.1 shows the results for the samples 1 to 4. The samples sintered at lower partial pressures (about 50 mm Hg) of oxygen showed higher tonductivity than those sinterod at atmospheri-. pressure of oxygen. An investigation of the dependence of the. conductivity upon the partial pressure of oxygen was undertaken next. The measurements were taken only after equilibrium had been set up, i.o. after approximately 15 hours. a was found to be a linear function of the partial pressure of oxygen. It can be expressed by the equation 1 Card 2/5 a = const x p o 2x 23070 Z/037/61/000/002/002/003 The Semiconducting Properties ... E133/E435 where p 02 is the partial pressure of oxygen. The values of x vary between 3.48 at 703*K and-4.96 at 856*K. We might speculate that the conductivity is due to either oxygen vacancies or to copper (or tungsten) ions or atoms in interstitial positions. In the monoclinic lattice, the second possibility seems rather unlikely. Assuming that the conductivity is due to the electrons from oxygen anions, we can calculate the conductivity as a function of partial pressure of oxygen and find that the probable mechanism is given by equation 1: (1) oxygen molecule -4~-oxygen atom + (oxygen vacancy)+ + e- (2) oxygen molecule Ftoxygen atom + (oxygen vacancy)" + 2e- At higher temperatures, a second mechanism (equation 2) might come into action. This assumption is supported by the fact that the dependence of log a upon 1/T changes at about 693 to 753*K (Fig.1). Measurements of the thermoelectric e.m.f. as a function of temperature supported the assumption that copper tungstate is an n-type semiconductor. The view that oxygen vacancies determine the conductivity of copper tungstate is in agreement with Card 3/5 23070 Z/037/61/000/002/002/003 The Semiconducting Properties ... E133/E435 Landsberg et al (Ref.11) and Pachera and Hauffe (Ref.12). The luminescent properties of cadmium tungstate also point to oxygen vacancies as the most likely defects in this substance, which is isomorphous with CUW04.

TITLEz Photovoltaic Effe_c_t~ ~Ona Thin Film of Cadmium Telluride W PERIODICAL: Zeskoslovensk~ casopis pro fysiku, 1961, No.2, pp.141-148 TEXT. The photovoltaic effect of cadmium telluride has recently aroused interest because of the possibility of its use in solar batteries. Various authors reported measurements of the photo- voltaic effect between cadmium telluride and various thin surface layers. The present authors studied the photovoltaic effect of thin films of p-type cadmium telluride evaporated onto a metallic substrate. The cadmium telluride was evaporated onto a layer of either tellurium or aluminium and the second contact was formed by metallic cadmium. The cadmium telluride contained less than 0.001% of Cul Pb and Si. The evaporation was carried out at room temperature at 10-5 mm HS. The area of the layers was about 0.5 or I cm2 and the thickness 9.6)x and 0.2 ji. The resistivity of the layer was approximately 10 ohm cm. Three samples were used for the measurements: a) Te-CdTe-Cd (smaller resistance); b) Te-CdTe-Cd (larger resistance); c) Al-CdTo-Cd. Card 1/3 23071 Z/037/61/000/002/003/003 Photovoltaic Effect ... E133/E435 All the cells showed non-linear d.c. characteristics both In the dark and under illumination. The maximum resistance occurs when the cadmium contact is positive. This in in agreement with the assumption of a p-type layer of CdTe which is also in agreement with the thermoelectric and photoelectric e.mj~ls,, The samples were highly unstable. From a.c. measurements of the resistance and capacity, it seems established that a barrier layer of the Schottky type exists in the cells. The internal resistance ford from measurements of the photoelectric a.m.f. was 4,,65 x 10 ohm for sample (a). The photoelectric current has beon found linearly proportional to the absorbed radiative energy within the full spectral range. The photovoltaic e.m.f. increases linearly with absorbed energy up to about 10 MV but shown a tendqtncy to saturate at higher energies,, Samples studied by the present authors did not show a maximum in their photosensitivity within the range of the wavelengths investigated, while commercial CdTe cells do show a maximum within this range.

Czech. patent, class, 59 a, 5; 42 e, 9. no. 95602, June 1.5, 1960 TEXT ~ A device for dosage of small amounts of fiquids (0 to 0.5 CM3) with an accuracy of � 0.00 1 cm3 is des- cribed. At the beginning of the operation cycle, pistons (P) I and 2 (cf. figure) rcmain in their initial positions, to the left and to the right of the opening 7 of the inlet channel 8 at a preciscly determin:d distance from a calibrated edge 9 located in a plane A perpendicular to the axis of the tube 3. This distance i5 established by means of a measuring screw 4 with a stop 5 pressed to it firmly. When P I is displaced in relation to P 2, which is kept in the initial position by the spring 6, the distance between the ends of both P pistons decreases and the excess of liquid passes into the channel 8. When the end of P I passes over the edge 9. the removal of the excess liquid stops and the amount of liquid which remained in the tube 3 corresponds to the predetermined dose. Further displacement of P I causes a displacement of P 2, which compmses the spring 6; as a result the dose of the liquid flows into the opened channel 10, after which the ends of P I and P 2 %hill touch one another The device may be used in pharmaceutical, chemical and food industries, for lubrication, injection of fuel into combustion chambers, etc. [Abstracter's note: Complete translation.] Card 1/2 Dosing device fot...

Directiona__ ouplers Made of Waveguides Perpendicular to Each Other q~ PERIODICALt Slaboproudy' obzor, 1960, Vol 21, No 2, Pp 72-78 ABSTRACT: Directional couplers are very often used in waveguide techniques. By means of the couplers it is possible to take some of the power from the main waveguide into a branching waveguide. The main parameters of the direction- al couplers are: the coupling loss and the directivity. The coupling is defined by V = 10 log P, P4 where P I is the power at the input (see Fig 1) and P4 is the power at the output 4, it being assumed that the direction of the propagation in the main waveguide is from I to 2 (see Fig 1) * The directivity is defined by Card 1/4 S = 10 1-0 P4 (2) P4 LI/C Z/039/60/021/02/003/037 E192/E535 Directional Couplers Made of Waveguides Perpendicular to Each Other where P14 is the power at the output. 4 when the propagation direction in the main waveguide is front 2 to 1. The directivity can be achieved by several. methods. In the following it is shown that comparatively simple wideband directional couplers can be obtained by combining 2 waveguides perpendicularly to each other and by providing the coupling hnle between them (Fig 1). The functioning of this system is investigated analytically. A rectangular waveguide shown in Fig 2 its considered. It is assumed that when the electromagnetic wave propagates in the z direction, the field is given by Eq!j (3):, for the propagation direction -z, the field components are expressed by Eqs (4). The excitation of electromagnetic field bv a hole can be investigated on the basis of the Bethe t4pory (Ref 1). According to this theory a small coupling hole between two waveguides can be regarded as dipoles which excite the electromagnetic waves propagating Card 2/4 in both directions from the hole, Under the assumption Z/039/60/021/02/003/037 E192/E535 Directional Couplers Made of Waveguides Perpendicular to Each Other that the wave in the main waveguide propagates in the direction p (see Fig 3) the propagation constants for the secondary waveguide which is perpendicular to the main one, are given by Eqs (5). In these A + is the propagation coristatit for the wave which propagates in -the direction z while A is the propagation constant for the direction -z. The quantities to be determined in these equations are the so-called polarization coefficients, These depend on the shape of the coupling hole, The coefficients for circular, rectangular and cross-nhaped holes are indicated in Table 1. Thus it is found that. the propagation constants for the case of the circular hole are given by Eqs (8), while for the cross-sbaped hole they are expressed by Eqs (9). The coupling loss for the circular wavegulde can be expressed by Eq (11) and the directivity by Eq (12). The functions F 9 and F H In these equations are defined by Eqs (10). Eqs (11) and (12) Card 3/4 were used to design a directional coupler for the wave ~~c Z/039/60/021/02/003/037 E192/E535 Directional Couplers Made of Waveguides Perpendicular to Each Other length of 6 cm, The results are indiciited in Figs 5 and 6. It was found however that coupling losses of about 20 dB could riot be obtained by means of a circular hale. For this purpose a cross-shaped hole was emjiloyed~ The coupling loss and the directivity of this type of coupler are indicated in Figs 9 and 10, In special cases; it is possible to employ couplers based on 2 cross-shaped holes. A coupling system at 20 dB with two cros8-shaped holes is illustrated in Fig 17. On the basis of the theory and some experimental results it is concluded that it is possible to design a directional coupler in such a manner that the coupling loss over the whole bandwidth of the waveguide will be practically constant and the directivity will be higher than 10 dB. There are 18 figures, 1 table and 11 references, 2 of which are Czech and 9 English. ASSOCIATION: TESLA Pardubice, Pardubice) SUBMITTED. October 1, 1959 Card 4/4 n.p.

Curvature of transition ourve Is the same for all radii of the curves; curves with different radii, e.g. r, and 1-2 (see Fig- ure 1) are joined with the transition curve at points ZO, and Z02 located at Ca~d 1/5 -9/035/62/000/011/o46,/079 Railroad transition curve A001/A101 distances 11 = np, and 12 = IIP2 = ?1,/r2 from the be-ginning ZP of the transi- tion curve. Here w - r1 - 11.8 nV2, where n - 10V and V is velocity. The ordi- nate of the end ZO of the transition curve is determined from -the expression: k 12 13 and tangent of angle formed by the tangent with the ahacissa axis, is the first derivative of the transition curve equation: y X2 X2 tg '~_rl I ~i~ ~ For the end ZO of the transition curve and tg 12. The coordi- 2-W nates of center S of the curve located on the normal at the point of joining the transition and circular curves have the values x. - I - r - sinA, Y. = k + + r - COSA. Radius P of the transition curve curIvature is determined from the expression: (1+y 12)3/2 71 Card 2/5 Railroad transition curve S/035/62/000/011/046/079 A001A101 where Y" = L- is the second derivative of the transition curve equation, Ir r1 and for point ZO the radius r In order to eliminate x - X - COS3 V P - COS3 il. * bending of the curve at point ZO, caused by the difference in curvature radii of the transition and circular curves, values of curvature radii ) are presented In the tables proposed by the author. Circular curves wittl the given radius r are Joined into a single transition curve in spots nearest to the maximum value of radius p, but in no case at the point of transition curve calculated for the ta- bular value of radiuz r. The transition curve length along the axis of railway is equal to l + 13 1 + 15 10 ~0_2 ~07 r (Figure 2); polar angle the angle In the beginning ZP of the transition cLave between the main tangent and d1rectiou to the end ZO of the transition curve, is .determined from the expression: tg k = 1 12 1 Card 3/5 Railroad transition curve S/035/62/000/011/046/079 AOOI/AlOl the length of secant d between individual points of the transition curve Is equal to d = V(kTkl)r + (12-11) angleT between the common tangent t' to both curves and secant in direction to ZP is equal to difference k- S; the projection length of the tangent onto the abscissa axis k 12 2r 1 -0 - tg~ rr 7- - 3 distance between point T and ZP: b = 1 St = ~ 1; distance between point T St k 3 and ZO: z.=-~~ ~~ the length of the tangent to The whole curve with 0 , in ; Q~ two-sided transition curves of the same length: to S + ys , tg 2 ; the total length of the whole curve with transition curves: do 21 0 + r - arc ~L-2?,.) where ~.C is external angle of extreme tangents. The tables proposed by the author do not call for any calculations while performing a railroad surveying. To survey the junction of circular and transition curves one has to calculate card 4/5 Railroad transition curve S/035/62/ooo/oll/046/079 A001/AlOl the position of the center of the circular curve on the common normal, lengths of tangents and the length of the circular curve along the axis of railway. These tables can be used also for a detailed surveying of transitIon curves. [Abstracter's note: Complete translation] Figure I N.
