Problemy difraktali i rasprostraneniya voln, no. 4,. 1965. Difraktsiya i izluchenlye voln (Wave diffraction and radiation), no. 4, 149- -165 TOPIC TAGS: wave mechanics, actiustic propagation, thin plate ABSTRACT: The author considers diffraction of acoustic waves in a liquid by elastic: plates subjected to pure flexure and having so-called edges of rigidity. The unique-, ness theorem for the problem is given. The simplest case is analyzed, i. e. dif- fraction of a plane acoustic wave by an infinite thin plate with a single edge of rigidity. It is assumed that the half-space y < 0 is filled with a liquid of den- sity p0 (the speed of sound is eo) and is separated f-m-m the half-space y > 0 by a Card 1/3 L 14o96-66 ACC HR: AT6002847 thin plate of density p (see figure), thickness H and constant rigidity D. The flexural waves which may be excited in the plate have a wavelength A. Another plate with a finite length in the direction y is rigidly fastened at a right angle to the Z first plate along the line x = 0, y = 0 on the y > 0 side of the half-space. This new plate is called the edge of rigidity with a height b in the direction y. The thickness- es of both plates h and H are of the same order of magnitude and the density of the material for the edge of rigidity is pl. The height of the edge b may be commensurate with the length of flexural waves in the edge, and consequently with those in the piate. It is assumed that h and H are considerably less than A. The boundary conditions for the problem are formulated and the solution is given in the form of an integral equation. This solution is analyzed and numerical calculations show that the edge of rigidity has a comparatively small effect on diffraction of a plane acoustic wave Card 2/3 L 14o96-66 AICC NR: AT6002847 by a plate. The calculations weze done for a a'teel plate with a thickness of 3 CM and an edge of rigidity with a variable thickness. The height of the edge was as- sumed to he constant and equal to 30 cm, I. e. commensurate with the length of a flexural wave in the edge. The frequency of the incident wave from the water was 5 kc. A curve is given showing the effective scattering diametar as a function of thickness of the edge. This curve shows resonance properties and Is made up of the' sum of longitudinal and flexural oscillations in the edge of rigidity. The longitu- dinal waves increase with h fr-am zero to some constant value while the flexural waves pass through extrema. at the points of resonance an the curve.

An editorial note preceding this article says that in the USSR and abroad, research is bein- con- ducted for designing amplifiers without output trans- formers. Such amplifiers produce very small frequency distortions. It may be expected that Soviet radio re- ceivers of the higher classes will be built without out- put transformers in the future. First, the author ex- plains three basic push-pull amplifier circuits for .-,,1,iCh tubes 6P18P mav be used. In the future, a special tube will be producbd for such amplifiers, A list of loud- speakers which may be used with such amplifiers is shown in a table: 4GD-5, 5GD-16, 3GD-11, 2GD-6, 1GD-17, and Card 1/3 06273 SOV/107-59-6-37/50 IF Amplifiers Without Output Transformers VGD-2o The author explains an IF amplifier with a 6N2P tube in the preamplifier stage and two 6P18P in the Push-pull Output stage. The circuit diagram is shown in Figure 2t the frequency characteristics in Figure 3. Two 2GD-6 woofers and two 1GD-17 tweeters are ubed. The sensitivity of t-he amplifier is 230 millivolts. -The acoustical system develops a sound pressure of 10 bar. Negative feedback of 19 db is Used. A two-channel amplifier with a Common preampli- fier stage was developed for receivers of the highest class- Its circuit diagram is shown in Figure 4. The frequency characteristi' c isshown in Figure 5. A 6N2P tube is used in the pre amplifier. Each of the two Output channels consists of one 6N2P and two 61118P tubes. The sensitivity of the amplifier is 0.2 volts. Negative feedback of 21 db is used for the higher frequency channel and 28 db for bhe lower frequency channel. T~,jo Card 2/3 06273 SOV/107-59-6-37/50 LF Amplifiers Iffithout Output Transformers 5GD-16 woofers and three VGD-2 tweeters are used. The output of both channels is 6 watts. Finally, the author describes a third version of an amplifier without an output transformer. Itscircuit diagram is shown in Figure 6 and the frequency characteristics in PiGure 7. Combined feedback is used. Negative feedback is employed in the driver and the output stages. Positive feedback is used inthe driver stage. This arrangement reduces the nonlinear distortions to 0.50115 at an output of 7 watts. The amplifier will reproduce frequencies from 20 cps to 100 kc. The driver stage consists of a 6N2P and the push-pull output stage of two 6Pl8P tubes. There are 6 circuit diagrams and four graphs. Card 3/3 POLYAROV, S.p doktor tekhn.naukt KOVOT)DCHENKO, V. inzh.

ABSTRACT The authors state that alloys formed on the basis of solutions with variable compositions have electric properties which are, to their full extent,dependent on the state of primary solutions in alloys..The authors show that the electric conductivity of the alloys is a function of the component-concentration as well as of the heat conditions of the alloys. The dependence of the electric conductivity of an 10 alloy on the temperature shows clearly the infl-dence of the number of dissolved atoms on the magnitud* and on the charactar of the electric conductivity. It is assumed that antimony in the lead-antimony system plays the role of an anion former. The dissolution of lead in antimony and of antimony in lead decreases the number of charge carriers for a-,B-solutions and for the eutectic mixture. The measurement of the hall-effect proved the assumption that the number of carriers decreases with the drop of temperature. The mobilityettdetermined by means of the hall- effect measurements passes through the maximum of temperature in the interval investigated. The thermo-e.m.f. of the alloys situated close to the autectic mixture, with 40 66,LV/degrees, decreases with the rise of temperature.

Specially prepared US single crystals and polycrystals wer trans- ferred to a darkroom. The temperature was varied from 83 to 3330K. C090 was used as the gamma source. The volt-ampere characteristics of CdS single crystals and polycrystals at different gamma dose rates and temperatures, the dosimetric characteristics at various temperatures, the relaxation characteristics at various dose rates and temperatures, and the volt-ampere dark characteristics were taken. It was inferred from experimental results that the gamma current was due to the energy of Compton electrons capable of displacing the lattice ions.

The measurements were made w;th a cryostat which is schematically shown in Fig. I and described. Co0O of 300 millicuries served as the gamma source, and the maximum intensity amounted to - 3000 pr/sec. For the measurement of the temperature dependence of condueti-vity, the crystals were previously heated in darkness for I hour at 100 0C, and then cooled, in darkness, down to nitrogen temperature.

Fig. 2 shows tan I dark ' f(103/T) for specimens of the first group. In the range of 166.67 - 250 0X conductivity increases only slightly with temperature. In thiE range, 6E , of the various specimens was between 0.08 and 0-14 ev. At higher temperatures the climb becomes suddenly steeper (some curves exhibit a salient point), and AE 2 was be'. twoon 006 and 00a ev (A E denotes the depth of the impurity centers). Fig.3 shows tho same for crystals of the sooobid group. For this, a io praotioul.- ly independent of temperature up to 485 K, while at higher temperatures there is a steep rise; all these curves exhibit a salient point. With a now to ohooklnp, the exiatenoe of local trap-like centers and to determin- ing their depth, the authors studied the thermostimulated conductivity of the various specimens. For gamma-sensitive crystals, current maxima were found at 175 and 290 - 3150K (Fig. 4), whereas gamma-insensitive ones had a maxim-am only in the last-mentioned range. The levels responsible for the peak at 3000K are located (as had been calculated by means of formula (2)) Card 2/4 82551 The Conditions for the Occurrence of Gamma 3/181/60/002/007/031/042 Conductivity in CdS Single Crystals M6/Bok 0.45 ev below the bottom of the conduction band. The results are finally discussed in great detail. Gamma absorption is mainly due to Compton scattering (92%), but also to photoeffect and pair Production. The quantum yield was found to attain 10D electrons per gamma quantum. The gamma- induced conductivity ( Ai -13a) is mainly due to impurity centers jo (shallow traps) and donor centers located near the bottom of the conduo tion band. Additional experiments -sere undertaken in order to test the role played by shallow traps in gamma conductivity. These traps can be caused by the introduction of bisatith impurities, as is shown by the appearance of peaks (Figs. 7, 8). Finally, the role played by shallow traps and donor oenters in the mechanism of the formation of gamma current is discussed, and the following mechanism is assumed: the Compton electrons arising on the scattering of gamma quanta are exciting carriers from band to band, exoitons as vell as electrons from lower atomic shells. In the case of the existence of shallow trapsv excitons can decay into negatively charged centersp and this decay is followed by a transition of electrons into the conduation band..The authors thank V.

TITLE: On the nature of gamma-ray conductivity in cadmium- sulfide crystals PERIODICAL: Ukrayins1kyy fizychnyy.zhurnal, v. 5, no. 2, 1960, 276-277 TEXT: The fact that rf-conductivity is found in certain crystals only of cadmium,,sulfide, makes the physical processes involved more difficult to understand. Thus, owing to non-homogeneous composition of such crystals in the vapor phase, an extraordinary spread in the values of the dark resistivity of the crystals is observed. The author obtained single'crystals of cadmium sulfide by a method (Ref. 3: E. Grillot, Compt. Rend., 242, 779, 1956) which yielded more hom- ogeneous crystals; the spread of dark resistivity did not exceed an order of magnitude of 1.5. These crystals can be divided into two groups according to the lag in their photoconductivity. To the first group belong the crystals for which an 80% rise (or drop) in Card 1/3 2558,1 S/185/60/005/002/018/022 On the nature of gamma-ray... D274/D304 photocurrent takes place in tens of seconds. An investigation of the temperature dependence of electrical conductivity for this group showed the presence of impurity centers with following activa- tion energy: donor-levels with AE from 0.4 to 0.12 eV, and from 0.5 to 1.2 eV; trapping-levels with AE3 from 0.08 to 0.13 eV, and from 0.5 to 1.2 eV. To the second group belong crystals which have no trapping levels with activation energy from 0.08.to 0.13; for this group the rise (or drop) in photocurrent takes place in a few seconds. It is noted that first-group crystals show a decrease in electrical resistivity under the effect of 'Y -radiation; they are called I -sensitive. The crystals of the second group are not' T -sensitive. Hence the author considers that the trapping centers with small attivation energy have an important role in the genera- tion of I-conductivity. It can be assumed that the Compton ele- ctrons excite the carriers and the. excit3ons 1. the latter, can in- crease the carrier concentration in the conductivity zone, i.e. lead to 't -conductivity.

Rev., 97, 1543, 1955) and (Ref. 6: Poluprovodnikovyye preobrazovateli energii iz- lucheniya, IIL, 1959 (Semiconductor Converters of Radiation Energy)), Card 2/3 On the nature of gamma-ray... 25581 S/185/60/005/002/018/022 D274/D304 showed that the great inertia of the cadmium crystals (the crystals of the first group - according to this article), can be explained by virtue of the centers of two types with a different electron- capture cross-section. There are no tapping centers in the absence of 't -sensitivity; this.should be expected with the exciton mechan- ism too, of T -conductivity.

During the heating nitrogen is continuously added with the flow rate being chosen in such a way that at 12000C a temperature drop of 10-150C occurs.
