Transistors 1vith a kmageneous base,, with a diffused basep -and with a diffused ant Intrinsic base (p-n-i-p transistor) am dIsc:ussed. The dependence of the drift, time ;Won the diffusion layer's configuration is -calculated, under certain simplify- conditions. Fbra, special cases the dependence of hole mobility an the con- Wag, jeentration of the doping atwo Is conelderedp and the maximum concentration in Ithe emitter region Is computed which gives the otplaun frequency behavior of the itransistor. It is then shown that the configuration of the diffusion layer ~plqys an IMortant role in the p-n-i-p transistorp whereas the total thickness 1 of the baoe ~ Is of ama] I IMortance., In this respect the V-n-I-p transistor dif- fers from the other transistor typos._ la conclusions, the theoretical avA experi- 'mental results 'ard -do4ared.

In the FeCl3 solution, in the absence of priming centers, the garnet is produced only under reducing conditions. In the absence of reducing conditions, the synthenis occurs above 520* when priming centers are introduced. Optimal conditions for the synthesis of YIG in FeC12 solution are found to be 450 -- 625* for mixtures with excess of iron oxide and 525 -- 540* for stoichiometric charges. The kinetics and the influence of the pressure on the synthesis of YIG in FeCl 2 solution are investigated. [Translatioi of abstract).

This study is part of a broader study by the same group of authors of the hydrothermal synthesis of rare earih element ferrites with garnet structure, which have valuable magnetic properties. Hydrothermal synthesis of YIG crystals was studied in the Y.O.- Fe 03- H20 - NaOH, Y20 -Fe20j- H20-FeC13, and Y203-Fe2O3- H.0 -FeCl. systems. Cryst;f formation, reac- t102 kinetics, and yield of YIG crystals were investigated at variable charge com- position, temperature, and pressure. YIG was synthesized at 450-550C from 5-50% NaOH solutions in floating platinium inserts in the autoclave but only from the charge rich JiA Fe203. Formation of YIG crystals in a FeC:L:j solution was detected within the 400-600C range at about 1500 atm., and with the charges of composition varying within 3:1 to 1:6 range of Y203/Fe 203 molar ratios. YIG crystals obtained from FeC13 COrd 1 /2 UDC: 546-723-,.61;1--31 : 549-73 51 solution without seeding, but only in a reducing medium, i.e., in the presence of Fe2+. Magnetite and orthoferrite crystals were forrwd simultaneously with YIG under these conditions. In the absence of Fe2+, YIG crystals alone were grown from FeC13 solutions only on single crystal seed in hermetically sealed titanium inserts and at above 520C. The seed crystal increased by 200-300% in weight. Synthesis of YIG in FeC12 solutions was pc~ssible only from the charges with 3:5, 1:3, and 1:6 Y203/Fe2O, mol. ratios. The product always contained some magnetite which was formed in the reaction of FeC12 with the Fe.03 of the charge. The simultaneously producted FeC13 plays an important role in the t~ynthetic process. High yields of YIG were obtained in FeCl solutions in4fthe 450-625C range from the Fe203-rich charges and in the 525-546r range from stoichiometric charges. The maximilm size of the crystals was 1-1.5 mm in FeC12 solutions containing FeC13 and 1.5-2 = in FeC13 solutions.- The crystals formed in FeCla solutions were better in quality4~ Recrystallization on a seed was not possible from FeCl solutions because of decomposition of YIG in these solutions.

The author first establishes the necessary condition, on the basis of which elementary TE or TM waves should exist in a curved waveguide of a.certain constant section along the guide. Then he proves that TE as well as TH waves always exist at the critical fre- quencies of the curved waveguide, deducing for this case a very sim- ply shaped scalar equation. Considered is a curved waveguide with a constant section and with perfectly conducting walls. The axis Card 1/3 It 24262 R/005/60/000/001/004/004 On some properties of curved waveguides D264/D301 of the guide represents a plane curve r. In this case, a system of orthogonal coordinates can be used, consisting of the s arc along the r- curve and plane cartesian coordinates 5 and 9 in the normal planes of the I- curve, the origin of these coordiiRates coinciding with the intersection of the r curve and the normal plane. Select- ed is the coordinate t in the plane of the F curve. In case of M type waves, the author deduces the equation ~e &U . 0 (16) Y 6'7. in which Y is the propagation constant. This O-qua-ion may be ful- filled if: V = 0, ), - oD , or 3U/a7 . 0. In the first case, the curved guide degenerates into a straight line, the second case cor- responds to a critical frequency of the guide, and in the third case all components of the field are zero. Thus the following important property results: In a curved waveguide of a certain constant sec- tion along the guide, transversal-magnetic waves cannot exist with a sinusoidal distribution along the guide, except at critical fre- quencies T = oD. In case of TE type waves, the vector potential is selected as follows: E : jwb, (17) 11 rot b Card 2/3 24262 R/005 ,/60/000/001/004/004 On some properties of curved waveguides D264/D301 with the condition div b a 0. (19) Contrary to the TM waves, in case of TE waves a case exists when they can be propagated in the curved guide at every frequency above the critical one. For TE waves, the following property results: In a curved waveguide of a certain constant section transversal- electric waves cannot exist with sinusoidal distribution along the guide, except at critical frequencies, )r = aD. There is a single exception, i.e. waves of TEmo type which can exist in the curved -uaveguides of a rectangular section. The critical frequencies of the curved waveguides may be defined as frecpiencies at which the r-ield intensity does not vary with the 'Is" coordinate. For M type waves, the author deduces the relation: a2F 2 2 + A-F EF + k F z 0 12 h 43 (29) 'a. in which F z hEs, For the TE type waves, an identical equation is obtained, F being equal with hHs.
