Abstract: 1,226,387. Semi-conductor devices. VARIAN ASSOCIATES. 5 June, 1968 [30 June, 1967], No. 26848/68. Heading H1K. In a bulk negative conductivity effect microwave device the active region is limited to a peripheral portion of the semi-conductor structure. The device may comprise a circular wafer of N-type GaAs having a concentric aperture so that the semi-conductor material forms an annulus to opposite faces of which a pair of planar annular Ni-Sn electrodes are alloyed. The device may be circular, Fig. 4 (not shown), or rectangular, Fig. 5 (not shown), and may be subdivided into a plurality of segments which may have rounded ends, Fig. 6 (not shown). One of the segments may be omitted to form a C-shaped structure, Fig. 7 (not shown). The use of a plurality of segments is advantageous in that the segments may be manufactured individually from relatively small wafers and subsequently assembled to form the annular device. As shown, Figs. 8 and 9, a plurality of square wafers 15 are soldered, in the form of a ring, to one face of a Te-Cu stud 18. The upper faces of the wafers are provided with Au tabs 19 which are interconnected by the metallized end of a ceramic cylinder 21 brazed to the stud 18. A Ni-Co-Fe alloy cover 22 is soldered to the outer ends of tabs 19. If the dimensions of the device do not allow the removal of the centre part of the semiconductor structure one of the electrodes may be formed in the shape of an annulus disposed near the periphery of one major face of a solid wafer, Fig. 11 (not shown). The radial width of the annular active region is about 1À5 skin depths at the microwave frequency and the thickness of the region is determined by the mode of operation of the device, the Gunn effect domain mode and the limited space charge accumulation (LSA) mode being specifically mentioned.

Abstract: 1,231,366. Time-division-multiplex exchange systems. SIEMENS A.G. 23 Jan., 1970 [24 Jan., 1969], No. 3286/70. Heading H4K. In a time-division multiplex telephone system subscribers' group highways MS1 to MSn are each switched to subscribers two-wire lines by switches ZS in one leg of each line, the other legs being commoned to a second wire of the group highway which is stood away from earth by a resistor R the resistance of which is high compared with the resistance of those legs of twowire inter-group highways I to N which are switched to the second wires of the group highways. The arrangement reduces cross-talk. Switching between group and inter-group highways is effected in both legs at each cross-point, the low-voltage legs being switched by opposed parallel diode pair arrangements, the highvoltage legs being switched by a symmetrical diode bridge arrangement, each of these arrangements incorporating a transformer secondary to enable each cross-point to be switched from a common transformer primary winding. The inter-group highways I to N are shown as sections of coaxial cable the external conductors of which are connected to earth by resistors W. The system may incorporate highways switched in the manner of subscribers' group highways but serving inter-exchange junctions with pulse code to pulse amplitude conversion equipment.
