approximating the circle, is performed~by a mapping funcTIon determl-ning the con-
formal map of the theoretical profile exterior, similar to the described, onto

accuracy up to minute quantities of second order is performed by the M.A. Lavrent,

plotting the theoretical profile, the S.A. Chaplygin mapping function. An analogous
solution is obtained for the cascade of arbitrary profiles. Assuming that-the

TM: The system of five differential equations is established for
ealoulating the rotor blade motion, when a stroke governor, horizontal and
vertical hinges, and a skew-control automat exist. It is assumed that the
angular velooity of the propeller blade turn amounts to less than 0.1 of the
angular velo.oity of revolution; the calculation of the aerodynamic loads is
based on the hypothesis of steadiness; the induced velooiry is given as a
trigonometric series. I

Abstract no-T546. Tr.Kazanak.aviate.in-tal 19589 38, 43-56
TEXTs The author considers the calculation of the potential flow
around of isolated profiles and of grid profiles of an arbitrary form by
an incomp-ressibl* fluid. The author's method for the calculation of the
potential flow around of an isolated profile is a certain modification
of the well-known method of Thoodorsen-Serebriyakiv. The nature of the
authorts method consists in the following:
We assume that it is possible with the aid of the known function to
construct a theoretical profile c which is little different - according
to the position and the curvature - from the given profile"O' so that
is satisfied with a possible exception of a finite number of points.
Here S (a) is the length of the piece of the normal of the profile c

an approximate construction of a function jr - f(z,Z), f(w e) - co,

Title : Additional conductivity of HgI2 under the action of x-rays
Periodical : Zhur. tekh. fiz., 25, No 9 (September), 1955, 1523-1529
Abstract : The authors discuss the problem of developing and studying the photo-
electric properties of effective semiconductor receivers of x-rays and
the fact that certain semiconductors when irradiated by x-rays change
their resistance by tens and hundreds of thousands of times, which
therefore can serve as indicators of x-rays of even insignificant in-
tensities. They note that S. V. Svechnikov (ibid., 22, 8, 1952) demon-
strated that high sensitivity to x-rays is observed in CdS sinae-crys-
tal, vhich is used now for certain practical purposes but is in limited
use because of its considerable lifetime of photocurrent carriers. The
authors discuss their experiments on BJ2, which shows extreme sensi-
tivity to x-rays and considerably less inertia than Cds as indicated
.L all
by oscillograms of photocurrent pulses (photocurrent in Rg12 ' 5 to
zero in time equal to 0.001-0-002 second). They study the voltampere
characteristics, lux-nApere characteristics, the sign of the photocur-
rent carriers. They establish that the photo oensitivity of Bg12 es-
sentially depends upon spectral composition of x-rhy nidiation and

C~wd 2/2 FD-3126
increases with the brightness of the x-rays. They show that the photo-
current carriers are electrons and that the photo-resistance of 11g1I2 is
of sma.11 inertia (time of relaxation equals about 0.001 second). Mumi-
nation by visible light can condition the increase in photocurrent-by

ABSTRACT Lecture delivered at the All Union Conference for Semiconductors in No-
vember 1955 at Leningrad. This paper deals with the following 2 problww:
1. Explanation of phenomena of electron processes due to absorbed olectro-
magnetic radiation. 2. Relation between optic and photoelectric properties
and the reasons for the particular characteristic features of individual
samples. A procedure was developed for purposes of breeding monocrystals
from a solution in acetone from a melt and by the evaporation of He from
the solid phase and in order to Produce polycrystalline plates ;A~ Rlms.
The same results war* obtained by investigations carried out both with
monocrystals and plates. Rectangular and sinusoidally modulatied light
produced by ordinary mechanical modulators was used. The life of photocur-
rest carriers was determined according to the descending branch of photo-
current pulses. It depends on the wave lenght and attains its maximum at
wavol*nghts which correponds to the maximum of photosensitivity of the
sample concerned in the visible'd6main of the spectrum. Additional illu-
mination with constant intensity with white or monochromatic light at a
wave I*jkgbtk of 55c, m increases the life of the photocurrent carriers. If

TI TLE Effect of Admixtures of Tellurium and Vapors of Certain Substances on
the Photoconductivitytbf Polycrystalline Plates of Mercurous Iodide
PERIODICAL: Dokl. i soobshch. Uzhgorodsk. un-t, 1958, Nr 2, pp 23 - 24
ABSTRACT: The authors demonstrated experimentally that even minute amounts of Te
(less than 0.001%) have a substantial effect on the mainitude and
character of photoconductivity in polycrystalline plat-ei of mercurous
iodide. In the presence of admixtures of Te photoconductivity increases,
inertness ordinarily decreases somewhat, and spectral characteristics
spread appreciably in the direction of the longer wavelengths. As the
concentration of Te is gradually increased, photoelectric sensitivity
rises, while specific resistivity and inertness fall off. The enhanced
Card 1/2 sensitivity and reduced inertness point to an increase in the quantum

vestigated samples was also observed when they were placed in an atmosphere of vapors
of a=onla, acetone, and ethyl and Isoamyl alcohol.

TEXT: It is shown that the sensitivity of mercuric iodide photoresistance
cells fed by alternating voltage exceeds by several times their sensitivity in
the case of constant voltage feeding. The explanation is that an alternating
field does not permit the formation of a space.cha~ge that would lead to sample

TEXT: The effect of vapor adsorption of certain substances on the photo-
conductivity of mono- and polycrystal specimens of mercury iodide, HgI2,was in-
vestigated. Vapors of ether and ethyl alcohol substantially increase the photo-
sensitivity. Vapors of isoamyl alcohol have little effect. Vapors of benzol have
practically no effect on the photosensitivity Of Hg12 specimens. The influence
of the vapors is explained by the fact that adsorption considerably decreases the
surface recombination rate of the photocarriers by increasing their life duration.
Tbis fact is confirmed by the investigations of the photoconductivity kinetics.
Vapor adsorption leads also to an increase in the dark conductivity of the speci-

ABSTRACT: A study was made of reflection and absorption spectra in the 400
700-m,d,z, range, of thin CdSO 25* CdSeo 75 films, 0. 4-0.8-/44 thick (the indices
indicating the weights of the Gilial components), obtained on cold and heated (up to
300C)backings. All the. films showed an inverse dependence of the effective
coefficient of reflection R on the thickness of the film at all temperatures. This is
explained by the fact that R is determined both by the mirror and diffuse reflection.
1/2

ACC NR: AR6033781
A lower R value in films deposited on cold backings is explained by the smoothing
out of the microrelief surface when a layer is deposited on a heated backing. The
absorption spectrum of films deposited on hot backings is shifted toward the long-
wave region, which is due to the somewhat larger amount of CdSe in the films than
in those formed on cold backings. The conclusion is reached that CdSx. CdSel-x
films represent a substitutional solid solution. S. Bureyko. [Translation of

at low temperatures. Investigation was carried out at 77K on single crystals of the
red modification of HgJ2, grown from a solution in an acetone. To detect the
electret state, a standard procedure.was used for measuring the polarization value
according to the initial deflection of the electrometer upon depolarization by light.
It is shown that the photoelectret properties Of ngJ2 are related to adhesion in thia.

ABSTRACT: Optical absorption and photoconductivity of HgJ sinfrle crystals was
investifyated. Prolonged exposure of HgJ crystals to light results in a chemical
Lransformation of I-IcfJ to HrJ,) with the separation of 1-1g. Consequently, the HgJ
sinlole c rystals were grown in the dark. 11-J was found to be transparent over a
wide speciral reo-ion.' A noticeable absorption starts with 5560 A
reaches its maxinium at 5600 A and then decreases again. From one
specimen to another, the absorption coefficient in the maximum fluctuates within

700-1000-cm Therefore, there is reason to consider that the maximum at
SM A is not the basic maximum. It was found that Hcri also possesses
considerable photoconductivity with a maximum of sensitivity (at room temperature:
in the vicinity of 55OU'A . The temperature coefficient of variation of the
half-w:dth of the absorption band of I - 10-3 $is

ABSTRACT: The photodielectric effect has been detected in HgJ When HeJ
2* 2
placed as a dielectric between capacitor plates was illuminated, an increase in
di
,,electric constant ir-' was observed. At low temperature this change is maintained
with time, and with decrease in temperature value!.P' itself decreases only slightly.
It is supposed that in HgJ2 the photodielectric conductivity is linked to the formation
of the space charge on the griiin boundaries owing to the electron localization in the
traps.

SLATION: The effect of the-contacts, the aging process and certain other proper-
ties of mercury biiodide photoresistors are investigated. The photoresistors were pre4
.,pared from pure mono- and polycrystalline samples and from samples containing selenium
impurities. The experimental investigations showed that it is most expedient to use
aquadag or Pt which are quite stable over a wide temperature range. Curves are pre-
sented showing the electrical field distribution in the samples immediately after the
deposition of the aquadag electrodes and after thorough drying-, these curves prove that
the photoresistars with freshly.deposited contact have only a very low transfer re-
sistance Aersas after the drying of the electrodes the transfer contact resistance

ABSTRACT: The photoelectrical and optical properties of SbJ3 specimens obtained
by crystallization from the vapor phase in air or vacuum were investigated. X-ray
structural analysis showed that the specimens obtained were single-crystals and
that those obtained under vacuum were more prefect than those grown in air. The
dark current depends exponentially on the temperature and has an activation energy
of 0. 9 ev. The width of the forbidden band determined on the basis of the longwave
boundary of the main absorption band corresponds to 2.14 ev. It follows, therefore,
