collector current is thus expressed by

The flow of currents in the system is represented in Fig.l. The
equivalent circuit of a spatistor, that is the capacitances and
resistances of the electrodes, should be evaluated separately for
each particular case, since they vary considerably deponding on the
characteristics of the structure. Dn the other hand, the
elements of the active portion (Ri, g, a, 0 and y) can be
determined for a general case even though they are coinparatively
complex. The parameters RI and p are independent of frequency
and these were evaluated in the earlier work (Ref.2). The quantity
P can be evaluated comparatively simply on the basis or Eq.(2) and
(3). The resulting expresaion for 0 is given by tho first
equation on P-314. Graphs of 0 as a function of tho frequency
parameter wT are given in Fig;.5, It is seen that the imaginary

part of 0 is a damped oscillatory function, while tho real part
tends to unity. Tlie quantity a is evaluated by conisidering tho
field produced at the emitter by a linear charge q , which is
parallel to the emitter. The situation is illustrated in Fig.6.
The resulting expression for m is given by the 3rd equation on
P-316. A graph of the function V is shown in Fig-7. By
examining the equation for m it is seen that a is dependent on
the width of the emitter a/W and the number of wavelengths
contained in the length of a path. The formula for Y is given by
the laRt equation on P.316. It is seen that y is dependent on
the relative width b/W of the current stream and the number of the
wavelengths contained In-its length, The relationship between the
parameter a and Y is also e-valuated. The circult given in the
article (together with the relevant parameters) is applicable to a
large number of important structures of the spacistor, and is valid
over the whole operating range of frequencies. The frequency
dependent parameters (0, a and y) are expressed in terms of the
geometric factors and the normalized frequency w'r. These

expressions are valid for the structures which can be approximated
by a plane-parallel system with a flat emitter. The atethod also
permits the evaluation of P in those cases where the depletion
layer in not plane-parallel; as regards a and y the method is
valid even if the emitter and the portion of the base near it
differ considerably in shape from the parallel model. There are

verse fields. Negative conductance can be maintained either in
pulse operation or when the tiqavel distance is so small that the
transit time of carriers in the N314AG is smaller than the time in
which the negative conductance state 113 destroyed. Criteria of pre-

TEXT: The spaoistor was proposed by Statz and Pucel (Ref3. 1,
2). It was found, however, that this device has a comparatively
low slope S and voltage-gain coefficient 14 , so that its
applicability is rather limited. In view of the above, it is
important to determine the dependence of S and IL on the
geometry of the device and other significant factors. In the
following, this problem is considered in detail. The model of
-the apacistor adopted is shown in Fig. 1. where a aemleonductor
crystal has a p-n junction which is displaced in the reverse
direction; the third electrode (emitter) performs the injection
of the current carriers (electrons or holes) into the depletion
layer of the junction; this region is marked by the slashed
circle in Fig. 1. The arrowed curves in the figure show the
paths of the injected carriers in the field of the de-oletion
layer. That portion of the crystal where the injected carriers
can move is the collector, while the region on the other side

of the depletion layer is the base of the device. Tho operation
of the device is analogous to that of an electron tube.
Further, it is assumed that the base and the emitter cof the
model are flat, as shown in Fig. 2. This simplification is
justit'ied by the fact that the concavity of the base is
accompanied by corresponding concavity of tho emitter tjo that
the former is compensated b; the latter. Further, thl,- model
neglects the fact that the depletion layer is limited in extent.
The flat parallel depletion layer (Fig. 4a) can be transformed
into a s mi-infinite layer (Fig. 4b) by means of the function

to evaluate the fields produced by various typos of charges.
Thus, it is shown that the field produced by a uniformly dis-
tributed charge, having a density +f), is expressed ljy Eq.
(see Fig. 5). A charge q , which i s uniformly distributed
over a flat strip AB (see Fig. 6), produces a field which is
defined by Eq. (4). On the other hand, a charge which is
uniformly distributed over a layer having a width 2b (Fig. 7)
produces a field which is axprosaod by the Inst equation on
p. 239, A charge distributod in the space limited 'by the
emitter, collector and two symmetrical planes (Fig. 8) results
in a field which is defined by Eq. (5). The field,produced by
a charge which is uniformly distributed in a parallel layer but
is nonuniforbi in the plane perpendicular to the plane of
symmetry (Fig. 9), is given by Eq. On the basis of the
above formulae, it is found that;

These formulae illustrate the dependence of S and Ii on the
geometry of the device. However, the three geometrical factors
W, a and b are dependent on the operating conditions. This
dependence is investlEated in detail and it is shown that S
is expressed by the last equation on po 210, where U. %7

connected to the device, it is possible to obtain an oscillator
or a unidiret;tional amplifier having an arbitrarily largo gain.
If at a given froquen,.~y the parameter g.,I. and 922 or R,l
and R22 are positive and if U lies between unity and 0 , the
devize cannot become an oscillator or an amplifier. An equi-
valent circuit of a spacistor which was des--ribed by the author
in an earlier, work (Refs. 3 and 4) is considered, The circuit
is shown in Fig. 1. The frequency dependent parameters oL, 0
and y in this circuit were :alculated in one of the earlier
works and were given graphicallyi the parameters It and R I
were determined by means of suitable formulae (Refs. 3 and 4).
In order to evaluate the U-function (see Eq. M) it is
desir~abla to simplify the circult of Fig, 1.~ The circuit can
be represented approximately by tho circuits of Fig, 6. The
Mason function can therefore be expressed by

Frequency Characteristics of Spacistor Triodes
On the basis of the above analysis it is concluded that a
spacistor has the following advantagos as compared with a
transistor: 1) It is possible to obtain very low base
resistances due to the Inher-ent pvoperties of the device,,
2) the emitter and the base in a spacistor can be separated
by uteans of a high-resistance material. The formulae derived
(as well as those of the earlier articles) are used to deter-
mine the maximum frequency of two spaciators. It is found
that the maximum frequencies can be as high as 9 000 Me/a,
provided the structure of the device is suitably chosen and
accurately controlled,

TUT; H. Kroemer (Ref. 1) has shown tbe.t p-type germanium or silicon
crystals having strong fields in the F-100] direction ("longitudinal"
dire,~tion) exhibit n-type conductivity in the directions perpendicular
to [100_1 (11transversell direction), On the basis of this effect a new

briefly described in the preeent "Letter to the Editor", Its theory is
oxplained in a merely qualitative manner, and some specific features of
its field- and charge distributions are mentioned, particularly the
fluctuation phenomena. In fact, the distribution of charge and field In

AlAgMg compound, the effect of natural aging exceeds the quenching effect, while
in more alloyed alloys it is, on the contrary, below the quenchiN; effect. The
maximum effect of artificAal aging is ahown by alloys in the solid solution range
which contain 10.8 - 13.2% of the AlAglfig compound.

mended in Reference 9, using 10% NaOH solution as an etchIng agent, Microhardness
was determined on a nti-,_3 (MT-3) device under 20 g load. The lattice parameter
was measured using the method of reverse X-ray exposure on a plane film with copper
radiation. Electric conductivity of the alloys was measured by the method of eddy
current on a device described in Reference 10. The secondary sections and results
of measuring the micronardness (H P_ ), the lattid-~ parameter (a) and electric con-
ductivity ('f) of the alloys of these sections are given in Figure 2. It is
shown that the results obtained agree with data of microscopical analysis and are
mutually consistent. It was found that on the secondary sections in equilibrium

evacuated quartz ampuls, e.nd left for 7 hr at this temperature. A part of
the samples was then hardened, and the rest was cooled to 4300C, After

ABSTRACT: A series of 49 alloys 'of the tungsten-M"01:ybdentvi-iitanium system weri
smelted from 99..95%-pure tw3gaten, 99.95%-pure molybdenm, and 99.9X-pure titanium.
A ternary diagram of tile system was plotted on the basis of data obtained by
physicochemical analysis.. It was found that tungsten and titanium have a considerable
solid-state solubility in inolybdenum, which slightly decreasea with decreasing tem-
perature* For instance, t"ie total solubility of tungsten and titanium in molybdenum
at 1500C and a W:Ti ratio of 4:1 was over 80%, but at 1000C it dropped to 77-78%.
The total solubility of a 14M ratio of 3:2 changed simiiarly when tile temperature
,dropped from 1500 to 1000. Addition of molybdenum to binary W-Ti alloys increases
!tile mutual solubility of components. At 1500 and 1000C, a continuoun series of
solid solutions is formed at respective molybdenum contents of about 20Z and 25%.

have boon investigated. From the data obtained the projection of the
ternary phase diag:ram on the composition triangle (see Fig. 1) was
plottod, in addition to several polythermal and isothermal sections.
It was found that nost alloys annealed at 1500C or 1000C have a
single-phase or two-phase structure and only a few have a three-phase
structure. Single-phase alloys consisted of a- and $-solid solution

ABSTRACT: In the technical exploitation of equipment its parameters
vary with time. As a result it is necessary to undertake
periodic maintenance and emergency repairs. It is
important to determine the optimumperiod and volume of
maintenance for reasons of economy and reliability. Since
in practice it is difficult to obtain sufficient
statistical information for an analytical solution the
following procedure may be employed. The mathematical
expectation of breakdown is found and if it Is less than
the time required for testing the equipment during
maintenance, the volume of the latter is considered
satisfactory. It is necessary to vary the volume and
Card interval between maintenance operations to determine
*%*,heir optimum value.
