Abstract :The author excamines the variation of the output characteris-
tics and current gain of point-contact transistors with
the properties of the materials used for its manufacture and
with various factors of constructional character. A point-con-
tact transistor with additional emitter is examined from this
aspect. The passage of a current of minority carriers through
the second emitter of this transistor increases the coefficient
(under certain conditions) to approximately 20. The optimi
operating conditions, the choice of the material, and the mode
of formation of the transistor with additional emitter are
analyzed. Curves are given for the dependence of the coef-
ficient of the transistor on certain constructional and
operating parameters. It is shown that it is possible to

ABSTRACT: This article presents experimental results concerning the effects

impravement in the current-voltage characteristics of the diodes& Mw (V-n)-

ABSTRACT: J. de Groot proved the following theorem concerning a topological
representation of groups: Jet G be an b1tr ;roup. Then there exists a
Hausdorff space T such that the group of all tolhomo)morphisms of T (under
composition is isomorphic with G. The space T can be chosen to fulfill some other
conditions, for example, to be metric or compact. A similar theorem for semigroups
and small categories is proved in this article. (Orig. art. in Eng'.] [JPRSI

TITLEs Colored etching of titanium alloys
PERIODICAL2 Zavodskaya laboratoriya, v. 27, no. 4, 1961, 424
TEXTt To examine the structures of titanium alloys types tT-2 (VT-2) and
Mfr-2 (IMP-2), the authors applied the methods of oxidizing polished
faces at elevated temperature (hot etching), and oxidation in the
electrolyte. In hot etching, specimens of HM17-2 (IMP-2) alloy were first
polished and then etched with a reagent consisting of one part by weight
of hydrofluoric acid, three parts by weight of nitric acid, and six parts
by weight of water. After careful washing and drying, the ground faces
were put into a.muffle furnace, heated for three minutes to 6000C, and
then air-cooled. After each treatment, the grains of the a-phase turned
blue or bluish-violet depending on their color orientation, whereas
those of the P-phase turned yellowish-brown. The larger number of in-
clusions in the a-phase in microphotographs is explained by the saturation
of the ground face with oxygen and nitrogen (which are stabilizers of the .2@1__'@@

a-phase) during heating to 6000C. Structural changes of the alloys may
occur in hot etching. Prolonged and frequent heating to higher tempera-
tures is therefore not suited for colored etching. Colored electro-
chemical etching may not cause any structural changes in the alloys,
Besides, a better colored pattern of the examined structure is obtained
by this method of etching. Electrochemical etching 2was conducted by the
authors at 120 v and a current density of 0.05 a/cm in the electrolyte
containing 5 9 of citric acid, 5 g of oxalic acid, 5 ml of orthophosphoric
acid, 10 ml of lactic acidg 35 ml of water, and 60 ml of ethyl alcohol.
Current was supplied in pulses of approximately 0-5 see. The clearest
pattern was obtained with Allff-2 (IMP-2) alloy after five pulses, and with
ST-2 (VT-2) alloy after two pulses. The color of the individual structur-
al components in colored electrochemical etching also depends on its
duration. The ground faces of the alloys types RHIT-2 (IMP-2) and:DT-2
(VT-2) turned yellow even after a short time of etching, and then
successively brown, violet, and blue due to longer etching. This
sequence repeated when the process of etching was continued. In hot and
electrochemical etching, the surface is recommended to be well polished,
washed, and degreased. For laying the structure open, it should also be

-'T: rffhe authors studied the structure, hardness and chemical composi-
tion of the surface layer of some titanium alloys. The structure of this layer
was modified by holding the titanium alloys in air-atmosphere at high tempera-
tures, so that their surface layer was saturated with oxygen and nitrogen. It
was found that this layer was characterized not only by greater hardness and the
presence of an alpha-affected zone but also by a content of alloying elemenis
different from the core, Experiments made with a titanium alloy containing 4%
Cr proved this concept to be correct. Micro-spectral analyses show that the Cr
content increased from 2.110 in a depth of 0.075 mm to 4.32% at 0.825 mm distance

cylindrical specimens were first subjected to thermal treatment under conditions selected on
the basis of the phase diagram sliown in Fig. I of the Enclosure. McLallographic examina-
tions of these specimens by either the black-and-white method (etching with 11F + IIN03 or
with 112SO4) or the color method described previously (Zav. lab., 1961, No. 4, p. 424)
showed anc.4,-solid solution of the interwoven or neccUc type in all cases. The precise type
of structure was found to depend on alloy content (Al, Cr, Fc, Si, B), ann"ing tempera-
ture and rate of cooling during quenching. Normal X-ray anglysis on the URS-70 machine
confirmed that the alloys consisted mostly of the---
