TEXT: Results are given of an experimental investigation into the
effect of chemical composition and of the form of barium, stron-
tium and calcium carbonate crystals on the emission current of,
oxide-coated cathodes. 4 types of coating, deposited according to
the same process on the cathode of a standard cylindrical diode
were investigated. 1) (Ba, Sr)CO 3 50:50% by weight, deposited from
nitrate solutions by reaction with Na 2C0 3' 10H20 (whisker crystals
having average length 5.95 and 4.7 microns). 2) The carbonate ae-

(spherical crystals with average diameter 3.0/U). The number of
samples tested in every series was 74, 64, 100 and 57 respectively.
The emission current was measured at a fixed heating power of
+ 0.5,ulf, corresponding to the temperature of 5230K. The diode an-
3de voltage was 5 V (to avoid the effect of ion currents). The am-
bient temperature error correcting factcr was calculated from

The measurements have shown a normal statistical distribution of
the logarithm of emission current in every series. Quanti-tative
evaluation of differences in emisEbn current of various series was
carried out statistically by means-of Student's t-criterion. For a
55 difference level (t = 1.96), the di.-E*ference between separate se,
ries is appreciable, the emission current increasinc with smaller
carbonate crystals. Spheroidal crystals were deposited by ammonium
carbonate, as compared with the whisker-type crystals deposited by
sodium carbonate. The trio2ibonate (Ba,Sr,Ca)CO3with the weight ra-
tio 47:30:10 produces a considerably greater emission current than.

mensions and chemical composition. This spread decreases when the
shape of crystals approaches that of a spheroid. The conclusions as
to the uniformity of the emission current may be extended over to

TEUT: A method of calculating the reliability 0f electronic valves
is given; it is based on the observed parameter -changes with res-
pect to their initial value and, to the frequency of failures equi-
valent to these changes. The equivalent failure frequency of a sin-

of changes observed in practicep is found from the condition of
working stability of a random selection of valves. A graph of the
failure frequency versus region of changes of the valve character- V/r,

PERIODICAL: A.rchiwum elektrotechniki, v. 10, no. 3, 1961, 783-787
TEXT: The author considers the quality of electron tubes as the
product of the probability of the lack of damage Ra and the condi-
tional probabilities of keeping the electrical parameters within
the required tolerances Rxil Rx2' ..I, R xi* In order to establish
the probability R the distribution functions of the parameter X
are taken as the Rhode current - Is, and the slope of its characte-
ristics - Ra. A test is described for the quantity n = '103 of the
electron tube BP80 working under normal conditions. During the time
ti the values of Sa and Ia were taken for each tube under test for
constant grid polarization. As random variables for the statistical
analysis the quantities of Sa(t and log Ia(t were assumed and

their normal distributions were checked by calculating the statist-
ics X2according to Pearson's relationship. The experimental and
calculated results are tabulated and proved to show the logarith-
mic distribution for the anode current and normal distribution for
the slope of the characteristics of the electron tube. To confirm
these results another test was made for conditions more severe than
the normal, i.e. for the anode voltage increased from 170 V to 250
V. In this case the normal distribution of Sa(ti) during time ti
was also observed. There are 3 tables and 3 Soviet-bloc references.

PERIODICAL: Przcglqd elektroniki, no. 1, 1962, 37-45
TEXT: Methods of estimation of.an unknown probability of a random event in a population are discussed on
the basis of the observed probability of such an event in n independent experiments, treated as a random sample
of this population. General principles of estimation of unknown parameters in a population are stated, and
it shown that the best estimate of a random event is its frequency, as observed experimentally. Methods of
establishing confidence limits for an unknown probability are thoroughly discussed. Several examples arc
given based on the practice of electronic production.

Statistical evaluation of the quality of electron
tubes
PERIODICAL: Archiwum Elektrotoohniki, v. 11, no. 4, 1962, 741-756
TEXT: Practical methods are discussed for evaluating the quality
of a batch on the basis of the percentage of sub-standard speci-
mens. The measure of quality of a batch is the probability that
at least one of the requirements will not be satisfied, called the
factor of demerit. Statistical analysis of a random sample permits
the evaluation of the demerit factor, i.e. to determine the confi-
dence interval (w', w") which will contain the demerit factor with
a confidence level 8: the theory of estimation is applied in the
analysis of sampling results. For alternative classification (each
item is either good or bad) Hanamaker's table'pf w', w" values is
reproduced for a lot (n) of 5 - 500; disqualified items number W
0 - 20 and the confidence level is one of 0.90. The top limit of
Card 1/3

the confidence interval (w") is termed the guaranteed factor of
demerit and 2 is the guarantee level. Nomographs of w" as a func-
tion of n are given for various values of z. In handling some mea-
surable parame*ters (parameters-class;II) the alternative clasbifi-
cation-is not sufficiently precise.*The demerit factor is estima-
ted on the assumption that permissible values of parameters are
limited on one or both sides. In the case of upper value limita-
tion the confidence interval for the unknown demerit factor is:

Laplace integral. Numerical examples are given. The combination of
alternative classification and normal distribution of a class II
parameter is considered, as well as the evaluation of the batch on

Statistical evaluation of

the basis of several parameters. The average demerit factor of a
production batch can be evaluated on the basis of m independent
samples with n1, n21 .... nm specimens each, by treating all these
samples-as one random sample of a lot equal to the sum of lots of
individual samples; formulas are derived for the confidence inter-
val in this case. Evaluations of the demerit factor on the basis of
two samples of unequal lots and unequal numbers of rejects are
compared and conditions are specified for when the two demerit fac-
tors can be regarded as identical. There are 1 figure and 1 table.
