ABSTRACT: 'flie article presents the results of an investigation of die evaporation rate of Be
during the thermal dissociation of die internietallic compowid CeBe as well as of die effect
of the addition of a small amount (0. .1 wt. %) of Ce on die evaporabill?y of/Be. CuBe 13 wa s o b-

i subliniation rates of die Be-0.417r, Cc alloy and of the products of dissociation of Cclie,3 were
determined by the niethod of evaporation from a cylinch-ical L~Lntaluni crucible with 'i rcsiaual
gas pressure of -!~ 2-10-6 111m jlg in the vacuu-ni chamber. The temperature was measured with

the aid of an optical pyrometer correct W 5,,~. Weighing of the crucibles was carried (jut
correct to �0. 0001 gby the continuous method on scales Mthout violating die vacuu-m. The
sublimation rate of Be with 0. 4% Cc was nicasured in Lhe temperature range ()20-1160'(',-
for this temperature range the saturated vapor pressure of Be over die Be-O. 4k Ce alkly is
described by the equation: log P = 9. 35-17, OOO/T. As for the sublimation rates of the compo-
nents of the intermetallic compound CeBe III during its thermal dissociation in the tempera-
ture range 1050-1250*C, the roentgenograms of the condensates gathered following evaporation
of the compound at 1100 and 12500C lack the lines of Cc and CeBe 13; therefore, appreciable
dissociation occurs above 1050T and flic entire sublimated i-natter may be referred to Be. 'ne
saturated vapor pressure of Be over the CeBc 13 compound during the latter's thermai disso-
ciation may be described by the equation: log P . 10. 475-18s 990/T. I'lie findingS were utilized

nonlinear differential equations has been applied under the
assumption of slowly varying amplitude and phase. This has
permitted the examination of systems with weak nonlinearitie~;
In order to consider systems with strong nonlinearities, the
present author proposes to apply the method where the decreuient
and frequency, and not the amplitude and phase, are slowly
varying functions, while the amplitude can vary at a finitc
rate in dependence on the numerical value of the decrement.
This method is applied to obtain expressions for the equivaleni
linearization of an essentially nonlinear element in a total

ABSTRACT- The author considers the following ploblem which frequently arises In connecUon
:wilh the design of autDmatic control systems. The system shown in Fig. I has an unalterable
sectioii based on a multi-dimehstonal controlled element. A controller must be synthesized
for maintaining Invariance In some set of coordinates of the controlled element either with
respect to some class of disturbances or with respect to all other variables in the system.
It Is further required that the invarlance resulting from synthesis of this control system must
belong to the class of pbysically realizable Invariance. The author shows that this problem
may be solved by Increasing the number of degrees-of-freedom of the entire system made up
of ob)ect and -controller. A class of automatic control Systems Is considered which operate
on the divergence prInciple with behavior which can be described by a sXstem of ordered
equations. Formulas are derived proving the -requirement for a controner which assures

finite-dimension%l object treated as a finite-dimensional controller. Expressions
are given for the control organs of an invariant system. The system was simulated
on an analog computer. It is shown that invariance may be produced with the aid of
a finite-dimensional object If certain conditions are maintained. An example is
given of the control system of an elastic object consisting of a uniform beam with
a tracking force at its end. It is further shown that the coordinates characteriz-A,

ABSTRAM As semiconductor triodes produced in series have a relatively
high noise-level, methods for the reduction of this noi3e and
of calculating the set noise must be developed. Problem3 of
practical calculatioh methods for set noise-in the construction
of measurement apparatus are here dealt with, it being assumed
that set noise is produced only by internal effects in the
semiconductor triodes, the author confining himself to problems
of calculation, four components of set noise are givent

gives formula (1) for the average voltage of this noise. The
decrease of semiconductor noise depends on the progress madd
in semiconductor production methods,. For the mean voltage
of noise produced by the Schottky-effect formulas (2) and (3)
are given. A decrease of this noise may be attained by re-
duction of the emitter- and collector current as well as of
the working temperature, Further, the equations (4) and 5)
are given for the mean voltages of emitter-current division
noise and thermal noise,. A formula for the probability of
the occurrence of white noise pulses with a certain minimum
magnitude is then given. The author next investigates the
internal noise on the basis of figure 1, Five noise-sourties
are given, which are arranged in two groups for practical
calculation, corresponding to the in- and output of the triode.
By means of formulas (6) and (7) the coefficients of internal
noise for emitter- and collector basic circuits (skhemy s
obahchim emitterom) are calculated, Formula(g) is given for

circuit. In the case of the practical calculations, the
correlation between the mean voltages of emitter, and
oolleotor-noise need not be taken Into account. The internal
noise depends on the triode parameter, the mode of Pperation
of the scheme, and on the internal resistance of the signal
source. Selecting the mode of operation with the least
internal noise is discussed on the basis of the diagram In
figure 5, i'n which the inner noise coefficient has a minimum
in the frequency range Il. For the reduction of set noise,
the triodes must be used in a circuit, in which a low eivittea
current, low collector voltage, and small temperature
fluctuations occur. There are 3 figures and 4 referenceo,
I of which is Soviet.

TITLEt d.c. measurement amplifier with semiconductor triodes
PERIODICALs IzmeritelInaya tekhnika, no. 3, 1961, 35-40
TEXTs Examination of the operation of d.c.-to-a.c. transformers with Ge
and Si semiconductor triodes of various types (A2 (D-2), A7 (D7),A20
(D20)) showed that the sensitivity threshold is at 5-5 mv. The trans-
formation coefficient, i.e. the ratio of the d.c. voltage drop over the
output to the d.c. voltage, has a value of 0.5 to 0.7. A sinusoidal
voltage as well as rectangular pulses may be used in transforming. Trans-
formers with germanium diodes have unsatisfactory temperature
characteristics; their voltage drift amounts to an average of 0.8 mv in
the case of eight-hour operation, also on fluctuations at room tempera-
ture. Transformers with silicon diodes operate, even on temperature
fluctuations by up to 450C, with a voltage drift of around 0.1 mv and a
current drift of 10- 10 a (after 8 hr). Low d.c. voltages may be trans-
formed on the basis of the Hall effect with the sensitivity threshold at

5()kv. However, the transformation coefficient of such transformers is
small and the latter are not stable on temperature variation. An
interesting type are transformers of small d.o. signals to a.c. signals
by means of semiconductor triodes. A sinuscidal or rectangular trans-
formation voltage is applied across base and emitter or collector of the
triode, while the measured d.c. signal is led over a resistor to the
electrodes of the emitter. The triode base current varies according to
the effect of the transformation voltage between 0 and ib max' Vhen the
input d.c. voltage is zero, then the output voltage is zero, too. On the
action of a d.c. voltage, the triode soon closes the circuit and becomes
saturated, which leads to the result that at the output of the triode an
alternating voltage appears, with a rectangle-like shape and an
amplitude proportional to the measured direct voltage. The lower limit
of direct voltage that can be transformed by such transformers is deter-
mined by the residual voltage u res and the residual current i res of the
triode. In the case of inverse connection of the triode, the residual
parameters are smaller than in the case of the usual connection with
common emitter; for this reason, in measurement transformation of weak

schematic diagram of a parallel and of a successive-type transformer with
inversely connected semiconductor triodes is shown in Fig.1 (a,b), and the
equivalent scheme is analyzed in Fig.1 (v). The voltage across the out-
put of the transformer during the half period of contact breaking is
