TITLE: On the Influence of fast states on the capacitance of a
structure consisting of a semiconductor, a dielectric film, and a
metal

ABSTRACT: The authors analyze the influence of fast states with ar-
.-Al bitrary energy spectrum, both discrete'and quasicontintwus, on the
S!panltance of a varactor, assuming that the conductivity of the di-
e4ectric -]Layer is InrInitesimally small and that the leakage through
the dielectric can be neglected. It is also assumed that the period
or 4he owinations In mach longer than the relaxatIon time of the
fast states,, so that the latter can enter in equillbrium with the

ROO Mt: AP6002002
space-charge region even at low frequencies. Earlier IniestIgationgi
of this subject- were confined to frequencies in which the fast states
were Inactive, or to fast states with discrete spectra alone. A
theoretical expression Is obtained for the relations Wtween the ca-
pacitance of such a structure ind the curvature of the bands on the
surface of the semiconductor for ldw frequendles. The effects of the
slow states to also considered. Methods of experimentally verifying
the results must Include simultaneinis measurements of the capacitance.
and of the field effect on structiae6a of this type. Such a method In
claimed to yield in= Iguous results. By way of an e-A le, a strue-
ture consisting of 31-310,-Netal, with the silicon being of the p-tXw
-on,, and the insulating film having a
and having a resistivity 100 ohm
0
thickness of 200 A and a dielectric constant 3.84. Comparison of the
results with calculations in which the fast states are not taken Into
accomt shm that the fast states give rise to a capacitance peak,,
whIch can be used to calcu24te-the number of discrete levels of f"t.-
states their energy positionsp and their concentration. Orig. art.

ranging from 350 to 41 500 kW and from 3 to 100 m head.
Measurements were made of the bearing pad and oil bath tem-

Speed curves were taken and the temperatures of the pads,
bearings and oil were measured as the sets stopped without
artificial braking. The sets were repeatedly started and
stopped without braking both immediately and at intervals up to

Itors for the auxiliary field of a magnetic dip,)le with unit momeiit sit-

the equations for the electric and magnetic surface currents are reduced
to Fredholm equations of the second type with finite integration limits.

rent Is solved approximately by the Krylov-Bogolyubov method. Graphs
showing the distribution of the magnetic current on the strip as well
~
as the direcTional pattern of the impedance strip excited by a slit of
finite width are presented. The graphs show that the position of the
impedance strip with respect to the edge of the semiplane has a weak ef-
fect on the distribution of the magnetic current in the strip. When
the distance from a strip to the edge of the semiplane is decreased,
there is a slight decrease in the traveling wave ratio for the current.
However, this effect is very small, although there is a substantial
change in the radiation pattern. The radiation pattern of the antenna
also depends substantially on the position of the latter with respect
to the edge of the semiplane. The authors are grateful to L.S. Yakobson
for programming the computer for the calculations. Orig. art. has: 6

ABSTRACT: A general case of excitation of finite-length impedance strips by
concentrated sources is considered. the strips are situated on the sides of an
arbitrary-angle *6 (see figure) infinite wedge, and the impedance is assumed to be
nonuniform. This general case in important for the
theory of impedance antennas. Assuming that the
distribution of volume density of the exciting electric
and magnetic currents is specified as are the impedance
boundary conditions for the lower side of the wedge, the
electromagnetic field is determined which everywhere
satisfies the Ntaxwell equations, at infinity satisfies the
Impedance stripa radiation condition, within the wedge sides satisfies
on a wedge specified conditions, and in other parts satisfies zero

high frequency oscillator for exciting a resonance detector with a stop frequency
characteristic and a frequency modulator for periodic variation of the oscillator
frequency in the range of the level variation. To increase the accuracy of dis-
crate measurement of the liquid levelM given points, the device is provided
with tank circuits excited by the oscillator at the same time with the detector.
The tank circuits are tuned to the frequencies determined by the given values of
the measured level. With the coincidence of the resonance frequency of the de-
tector and the resonance frequency of the corresponding tack circuit, the signal

It was found that for i - I the solutions ar,~ entirely differenti hence,
the invariance condition8 are not realizable, whereas for i 0 1 the
solutions to the two systems (10) and (11) are identical; hence, the invari

AA before, the two cases i. - I and i f I are considered. From an
analysis of the transfer function, it follows that this function should
represent the difference of two transfer functions at least. [fence, a

principle ID nonlinear systemst In nonlinear systems which belong to two-
loop systems, nonlinearities and variable parameters in any elements of
the system, except the parallel loops ` do not affect the fulfilment of
the invariance conditions. Further, if a nonlinear element is present in
one of the parallel loops, its effect can he compensated by introducing
nonlinear feedback into that loop Concluaions, An analysis of the mys-
tems for which the invariance conditions can be fulfilled shows that these
are two-loop or multi-loop systems, Nonlinearities and variable parameters
are either not effective or can be compensated. The fulfilment of the
invariance conditions enhances considerably system performance. In the
discussion, A. Yu lablinskiy considered the complete compensation of
external disturbances in gyroscopic systems- There are 3 figures and 12

TITLE: Investigation of self -oscillation in automatic control
systems with logical devices
PERIODICALi Izvestiya Akademii nauk SSSR, Otdoloniya tekhnichaskikh
nauk, Energetika i avtomatika, 1961, No.3, pp-3-13
TEXT: The article considers automatic control systems of high
order, containing logical devices for processing the signals
obtained from the controlled object. It is assumed that the
logical device processes two input signals, each taking on three
values (+l, 0, -1), and yielding a single discrete output signal
for activizing the controller. Such a system is shown in Fig.1,
where I - the regulator, 2 - the regulated object, 3, 5 - linear
amplifiers, 4, 6 - nonlinear devices with characteristics shown at
the bottom left and the bottom right parts of the figure,
7 - the logical device, 8 - the servomotor; a is an
intermediate point in the object where a lead signal is obtained,
0 is the point where the error signal is obtained, corresponding
to the discrete functions Ux and Uy respectively, and U is
the output from the logical device. The main purpose of the

logicaldevice is to determine whether the lead signal and the error
signal have identical or opposite signs and to generate a
corresponding signal for the servontotor. For an output signal
consisting of five discrete values (+ Ul, LU2. 0; Ul > LJ2), the
functional table is given by Table 1. It is desirable that the
phase shift between the x and y signals be in the range
0 < (P '< go*. An elementary discussion is given on the
realization of Table 1 by contact networks, using simple Boolean
algebra. Oscillations in the system are examined by the method of
harmonic linearization of the nonlinearity (expansion in series
and retention of first term). The coefficients of harmoni.:
linearization are functions of the lead angle y, the parameters
of the logical device, the amplitude and frequency of oscillation.
The characteristic equation for self-oscillation of such a system
will be an equation with constant coefficients. The behaviour of
the linearized system at the stability boundary can be found by
a method of Ye.P.Popov and I.P.Pal'tov (Ref.2: Approximate methods
for the investigation of nonlinear automatic systems. Fizmatgiz,
.196o). The method given in the paper can also be used for logical

devices with inputs obtained from the error and feedback siTnals,
or other such combinations. It can also be extended to sy:3tems
containing logical devices with three input coordinates and a
single output. There are 4 figures, 4 tables and 7 Soviet
references.

ABSTRACTs Recently Wdssbauer discovered a now aspect of esdesion and scattering of
gem& rays by nuclei in solids. A certain fraction of theme rays of the nuclei of
Ps solid Is emitted without Individual nuclear recoil. Instead, the recoil Moleen-
Itum is delivered to thi crystal lattice as a wholep resulting in negligible Doppler

*ecise resonance line in the sodesion'or absorption spectrum. For example, the
