ABSTRACTt Research aimed at studying conduction processes associated
'with charge-carri-or Injection Into organic semiconductors has been
startedo~ It Is noted that lately a great deal of attention has been
paid to the problem of obtaining nonlinear and nonsymmetrical volt-
ampere characteristics1for organic semiconductors. To this end an
organic aemiconductor-electrode contact was constructed by applying
2 Cul electrodes, or a Cul and an aluminum electrode by vacuum

.sputterin.gkaeross single crystals of anthracene. It was found that'
a nonlinear.volt-ampere characteristic is obtained, j^~*Vn, where
n - 8-10, regardless of.thenature of the second electrode; the
characteristic is symmetrical if the electrodes are both of Cul, and
nonsymmetrical if one is Cul and the other Al. At the highest voltage
used (--500 v)0 the rectification factor attained 3-5 orders [sic].
It was shown that conductivity is determined by the injection of holes
from the CuI electrode into the anthracene crystal, and that injection
is increased by illumination of the CuI electrode with monochromatic
light of theappropriate wavelength. Orig. art. has: 3 figures. [SHI

ABSTRACT:~j The authors descr\jbe a diode emitting visible light, based on gallium
phosphide*'4ith diffusion n-y junction, and describe some of its photoelectric ch r-
ic_t~;istics. The light radiated by the diode is produced by recombination of non-
equilibrium carriers through the impurity levels in the forbidden band, or by band-
band recombination (Fig. 1). The volt-ar~pere characteristics taken at room tempera-
ture and at liquid-nitrogen temperature exhibit a sharp breakdown in bath the forward
and inverse directions. The spectrum at liquid-nitrogen temperature has three peaks
at 7100, 614o, and 5650'Aj which successively decrease in amplitude with decreasing
wavelength. There Is n~_&dequate explanation for the structure of the spectrwn. Ac-
cording to preliminary data) the time constant of the radiation is 2 X 10-7 sec. The

TITLE: Photoelectric characteristics of a two-tcrminal p-n-p-n type nsistor switch

ABSTRACT: The article deals with the method of fabrication and photoelectric characteristics
of germanium-base p-n-p-n type transistor switches. The starting material was a p-type
wafer with a resistivity of 5 ohms- cm. and dimensions of 1. 3xl. 3x0. 08 mm. Twop-njunctions
were obtained by diffusing antimony into both surfaces of the original wafer and the third, by
alloying indium into one of the diffused layers. Ohmic contact on the opposite side was accom-
plished by doping with tin (Fig. 1). In the presence of a fixed bias lower than the switching

voltage the device is in the "off" state (point A on V-1 characteristic in Fig. 2) and displays a
high resistance of the order of several megohms. On illumination the switch changes from
"off" state to "on" state (point B in Fig. 2) considering that the fixed bias voltage is then'
sufficient for breakdown of the center p-n Junction. In this position the resistance of the de-
vice is of the order of several ohms. An Investigation of V-I characteristics in the presence
darkness and various degrees of illumination conclusively proved that switching voltage de-
creases with increasing Illumination. The minimum illumination required to switch the de-
vice is of the order of 100-150 lux. Further improvements in the design and fabrication of
transistor switches should make it possible to develop more photosensitive and stable devices

ABSTRACT:The usual methods of making calculations or the thermal
expansion of pipework do not allow for the deformatioLs
due to twisting in planes other than the plane of a,~It-icn
of the torque. Moreover, in ca-1culating static torques
and moments of inertia oi bent sections o' piping it is
assumed that their elastic centre of gravity coincides
with the physical centre of gravity. There is little
infomation in the literature about the magnitude of the
errors that result from these assumptions, but for a
particular case it has been evaluated at 3% and in anot-her
case 81/4. It is accordingly of' interest to make a direct
Card 1/3 comparison between the results of calculations inade by

the ordinary method and by a method which allows for the
secondary angles of rotation and for differences between
the elastic and physical centres of gravity of bent sec-
tions of piping. The results of' such a calculntion for
the pipe runs illustrated in the sketch are tabulated.
The suppqrt reactions are related to the end located at
the origin of coordinates. '2he more complete method of
calculation was developed by the Eastern Branch of the
All-Union Thermo-Technical Inst~tute, and allows for all
deformations due to bending and'twisting. Although the
calculations have only been made for a limited number of
pipes and types of configuration, certain conclusions car,
be drawn. In calculating the main stress, the method of
the elastic centre of gravity gives nn error which seldom
exceeds-3cY4. When the bent and straight sections are not
parallel to any of the reference axes the error can be 50m',
It is in such sections that secondary angles of twist
Card 2/3 occur, and in some cases the error in calculation of the

reaction at the supports can be 16~-. It should be
noticed that the error is not on the safe side, and often
underestimates the reactions at the supports and the
stresses in the piping. It is recommended that appro-
priate allowance be made for this fact when designing pi-De
runs.

TITLE: Determination of the Stress due to Weight-loading in the
Design of Piping
PERIODICAL: Teploenergetika, 1960, Nr 1, pp 92-93 (USSR)
ABSTRACT: In the ordinary way the weight of piping . gives rise to
additional stresses which may be neglected when compared
with those due to internal steam pressures. But the case
of an overhanging bend between supports presents certain
difficulties. Available semi-graphical methods of
allowing for the weight of piping in this case are rather
unsatisfactory. Accordingly, the Eastern Branch of the
All-Union Thermo-Technical Institute derived formulae (1)
and (2) for the reactions at the support next to a bend.
By plotting the nomograms given in Figs 2, 3 and 4, the
constants entering into these equations were determined.
The use of these nomograms leads to more accurate results
than the empirical formulae used hitherto. There are
4 figures and 2 Soviet references.

TITLE: The coefficient of linear expansion of steel

TEXT; An experimental study was made of the coefficient of'
linear expansion on specimens of steel IKhl8Nl2T cut from
industrial steam piping. Currently available published data fo-
this steel are apparently too high by 10%, because at working
temperatures the actual displacements of steam lines were very
different from the calculatecLvalues, The new values of mean
coefficient of linear expansion (a) are as follows, These valu-
are about 1110' lower than those given in handbooks. As the
equipment used for the measurements was not entirely reliable
the authors recommend further investigations.
