TITLE: Testing Apparatus for Semiconductor Diodes and Triodes
(Pribor dlya proverki poluprovodnikovykh diodov i triodo-'r)
PERIODICAL: Priborostroyeniye, 1959, Nr 2, pp 23-24 (USSR)
ABSTRACT: The apparatus developed works as follows: by means of an
oscillograph the VA-characteristic of the crystal diode or
triode is recorded. The diode (or triode) voltage is laid on
the vertical deflection plates) the voltage of a calibration
resistance which is series connected with the diode is con-
ducted to the horizontal deflection plates. The electron bean
traces on the screenthe VA-characteristic of the test
instrument. The steepness of the VA-characteriatic i.s a
measure for the quality of the diode or triode tested. Both
the right and the left part of the VA-characteriistic.canbe
checked by,the apparatus. When checking the right part-,!,of the
VA-characteristio, i e, when the diode lets pass a current
the a. ce voltage is conduoted to the test diode over the
contacts of a commutator and over a variable resistance of
Card 1/2 the gage tube 6Kh6S. When checking the left part of the

SOV/119-59-2-9/17
Testing Apparatus for Semiconductor Diodes and Tri6des
VA-characteristic the a. a. voltage is conducted over the
gage tube 6Kh6S shunted by a variable resistance. The
preoision resistance for measuring purposes is chosen in such
a way that the voltage is much smaller during the work
position of the diode than in.the opposite case. In this way
an extension of tho left pa-"t of the VA-characteristic is
achievod. The apparatus is fit for measuring point, contact
and junction diodeso The apparatus is housed in a Hight metal
case of'the dimensions 240 - 170 - 150 mm. Its weight is
2.5 kg,..The basi 'c circuit diagram and a photograph of the
apparatus are given. There are 2,figures.

TITLE: Measurement of the Wearing- and Interruption Time of Electro-
magnetic Relays (Izmereniye vremeni srabatyvaniya i otpuskaniya

PERIODICAL: Priborostroyeniye, 1959, Nr 6, p 23 (USSR)
ABSTRACT: The measurement mentioned in the title is difficult, as it
calls for the application of a loop oscillograph. The author
reports on his patent (Ref 1), which allows a simple and quick
measurement by the utilization of the stroboscopic effect. A
figure shows the diagram of the measuring device consisting of
a rotating contact releasing the relay and a measuring bridge,
by which a rotating neon lamp is switched off as soon as the
relay under investigation begins operating. There are 1 figure
and I Soviet reference.

settlemeats (fortbe pxrP61Ms*ewitft Geography) aaddrding to' their .1
runcti ons (should they be looked upon as urba~a places or
purely rural settlements) and population density. The
iresent-day classification into sel'skiye poseleniya
rural settlements), poselki gorodskogo tipa (urban
I
places), and goroda (cities) is inadequate since it
does not reflect the latest develoDments in the So-
viet economic geography. The author proposes to cre-

ployed in agriculture (Figure on p 111). Among
other things, the article gives the following sta-
tiStiLcal data: according to the TsSU USSR, 5Wo' of the
Soviet population were employed in 1956 in industry
and 43 % - in agriculture; in 1957, there were 78,900
kolkhozes and 5,80C sovkhozes in the USSR; at the
begijming of 1959, the number of Soviet cities with a
popu:Lation of more than 10,000 came to 11188; their
total amounted to 79,700,000 or 3856 of the Soviet
popul ~.ation. The article also cites author O.A. K-on-

ABSTRACT: The following is a general and short suinrey. When investigating
the microstraoture by means of ordinary metal microscopes the
aistribution of the components with an increase of the oraer of
magnitude of 120 is observed. In order, however, to ascertain the
appearance of the carboniferous powder, an order of magnitude in-
oreasea to 350-400 is necessary. In some, single cases the investi-
gation of the microstructure of oarboniferous substances aces not
suffice for the determina.tion of the ocmditiona for the formatign
of the investigatea compositions. In these o&ses it is useful to
apply the method of measuring the microstrength of structural
components. Measuring microstrength makes it possible to obtain
a more exact structural analysis of the compositions; soot-tar,

Study of the micro-struature and inicro-hardness of brushes oan

speoial features of brush manufacture. The procedure used for
polishing brush surfaces for microscopic examination is d6soribed..

Different types of strkoftre may occur even with a given formulation

which the porous, monolithic mad normal structures are discerned.
Sometimes examinations of niero-structure do not suffice to elucidate
the conditions of formiLticit of brush eumponition, or to identify
the constituents. In this cams, measurements of their micro-
hardness in helpfal. The methed.of m"ing the micro-hardness

without special treatment of the surface; the treatment used in
other cases in described. In order to investigate the influence of
composition on micro-hardness, samples were made which included
different proportions of graphite, carbon black, and binder. Each of
the formulations was pressed at 1500 kg/cm2 and -then fired. The teet
results, given in Table 2, show that the micro-hardness of the
natural graphite in the various compositions remained unchanged,
Ailat that of the carbon black altered considerably. The
significance of the figures for the different formulatious is

PERIODICAL: Zavoaslmya Laboratoriya, 1958, Vol. 2Jp, Nr 1, pp. 62-63 (USSR)
ABSTRACT: In the introduction it is sa--",d that such in-vrestigations are of
great importance for produoti.on. In this comiection it is mentioned
that the alloys; copper-lead-tin, or copper-t-`Ln are characterized
by phasse transfonnations with the formation of intermetallic -ohases
already at not very high te=peratures. In order to obtain the
necessary qualitative impression of these transformations the in-
vestigations of microstructure as well as hardness tests were car-
ried out for each component during heating. For this purpose a
special device is used vihich was fitted onto the working table of
the microscope or of the device used for testing ha-rdness. This
device is used as follows: the sample (8x5x2C ma) is clamped be-
tween two massive copper plates one of which is adjustable by means
Card 1/2 of a screw. A current is fea onto these plates so that they form

a heater. As these plates are massive, heating takes place mainly
in the sample which, aa to its diatnetor, is oormiderably moro
narrow. Tempamture of the sample is measurcd by means of a therulo.-
couple which is connected to the sample by means of a textolite
bolt. In order to avoid undue heating of the objective of the
micro3cope, this device is covered by a mice. plate which has an
opening through which the sample way be watched. In this manner,
among other things, the compressed samples of powders of copper,
lead, tin, and graphite (which are used as iraterial for the pro-
auction of electric brushes) I can be investigated microscopically
at various temperatures, and the structural tran3formations as
well as the follorring transition to the state of melting ran be ob-
served. It was possible to carry out similar tests also in apparatus
for the testing of hardness, Ther~ are I figure and 2 Slavic refer-

ABSTRACT: Thementioned plastometer is meant for the investigation of elec-
tric materials and etc.It conaibts chiefly of a cone that pene-
trates into the test sample by variable d.ead load. A certain
temperature can be fixed by a heating element and a contact ther-
mometer. The test samples are prepared irt a press. The investi-
gation method with a conical plastometer was already developed
by P.A. Rcbinder (reference 1) in order to investigate the tan-
gential stress. The conus penetrates into the test samples more
and more slowly so that the penetration depth forms a certain
function with the duration of the penetration (graphical repre-
sentation). By a formula the tangential stress can be calculated.

PERIODICAL: Vestnik elektropromyshlennosti, 1960, No.7, pp.38-43
TEXT: The results are described of field investigations on
photoelectrIc transducers which weret carried out between August 21
and September 21, 1959 in the region of Byurakan (Armenia) at an
altitude of 1800 m above sea level. The electrork-pole transitions
in the photo-elements were produced by thermal diffusion, accom-
panied by the formation of a naturally transparent film on the L
surf&'ce of the photo-elements (S.G. Zaychikov and T.V.Lysenko par-
ticipated in developing this method). The investigations were
carried out on a battery consisting of 28 series-connected sections,
each of which contained parallel-connected elements glx-ed onto an
insulated base. The sections were on a frame mounted on equipment
which was orientated automatically -to face the Sun. The working

surface could be protected by a removeable glass. Soldered leads
were available for measuring the characteristics of the individual
secti-na. The electric parameters were measured by class 0.5
instruments; the temperature of the ambient air (in the shade) and
of the objects of investigation were recorded by an automatic
instrument. To clarify the influence of temperature on the
characteristics of the individual photo-elements, a set-up was used
for cooling the photo-elements down to +100C and heating to +1600C,
whilst maintaining unchanged the natural illumination of the Sun.
The changes in the characteristics of the batteiry and of its
individual sections as a function of the intensity of the incident
radiation during the day were recorded continuously, using a
thermoelectric ictinometer with a galvanometer and an albedometer.
Zxperiments were also made to assoss the possibility of concentrat-
ing the light flux onto the surface of ph6toelactric transducers by
means of mirrors, using for this purpose a battery on an insulated
panel provided with hinged flat mirrors. The influence of meteoro-
