Abstract An investigation was rmd of the properties of ZnTe as a.
semiconductor. The ZaTe was synthesized in pure nitrogen at
a temperature of 8000C. The conductivity of zinc telluride
was measured in a temperature range from 0 to 1400C using
a'thin copper-zinc telluride-copper layer. Plots are con-
structed for the dependence of logd- on 1/T and the activation
energy L W =- 3.94 x 10-4 (109 6- 1 '109 d-2) (1/T2 -1/Tj) electron
volts is calculated and is found to be on the average 0.25
ev. No photoeffect was observed in zinc telluride. The
theTmal emf was measured with a method described by Frank
(Referat. Zhux Fizika: 1956, No 10., 29o62) with a cu-znTe
contact. It turned out that the value of the thenml emf
was 0.5 mv/deg. The conductivity is of P type. Bibliographyj

ABSTRACT: The appearance and disappearance of red luminescence of
zinc selenids, due to reductlion and oxidation media and
an atmosphere o-10 inert gas (nitrogen) and 7acuum were
observed. 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.

analysis. This sample showed inten3lve red luminescence
under the action of electrons. 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

TITLE: The Semiconducting Properties of Copper Tungstate
PERIODICAL: Ceskoalovenskyo' casopis pro fysiku, 1961, No.2,
pp.13,5-140
TEXT:; The semiconducting properties of tungstates have been
inadoquately studied. 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

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

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

The luminescent properties of cadmium tungstate also point to

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.

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. There are 7 figures and 11 references:

abstract 32.4.218 P. 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.

It was found that the number of leucocytes increases two days prior to deliver,,
At the beginning of delivery the number of white cells reaches a value of 15,000 to
25,000 and drops to normal during labour. The number of lymphocytes decre3sea
to as little as 5% during tabour. The retation of leucocytes and lymphocytea is
illustrated by several graphs. The authors think it of practical value that the in.

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

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

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)

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.

TITLE: Railroad transition curve
PERIODICAL: Beferativnyy zhurnal, Astronomiya i Geoaeziya, no. 11, 1962, 12 -

no. 5, 84-88, Czech)
TEXT: The author recommends the following method of calculating a rail-
road transition curve having the shape of a cubic parabola
P x3 x3
To secure a smooth transition of a railroad way into a circular curve, it is ne-
cessary that the center of the latter would be located on the common normal to
it and to the transition curve. 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

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:

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

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

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
