Title: Improvements in or relating to control arrangements for electric locomotives
IPC: B60L9/28
Filed: 1952-04-09
Abstract: 719,652. Control of A.C. and D.C. motors. GENERAL ELECTRIC CO., Ltd., and FRIEDLANDER, E. S. April 9, 1953 [April 9. 1952], No. 9093/52. Class 38(3) [Also in Group XXXV] A traction system comprises an alternating- current motor 15, which may be of the synchronous type, mechanically coupled to a direct-current generator 16 arranged to supply a direct-current motor 20 which, in turn drives a frequency converter 21. Traction motors 25 are supplied from the frequency converter and the torque of these motors is controlled by regulating the magnitude of the current fed to the machine 20 from the machine 16. The machine 15 also acts as a phase converter since it is energized from a single-phase source and provides the machine 21 with threephase current. A shunt field winding 57 of the generator 16 is connected to a boosting or bucking exciter 50 which has a field winding 52 carrying the armature current of the machine 20. A control field winding 56 of the exciter 50 opposes the winding 52 and is energized from a constant voltage source through a double reversing potentiometer 30, 31, and a permanent magnet generator 62 which is driven by a synchronous motor 63 fed from the output slip-rings of the frequency converter 21 so that the excitation of the generator 16 is modified in dependence upon the frequency of the current fed to the traction motors. Thus, when the output frequency of the machine 21 is low the excitation of the direct-current generator is arranged to be greater than when the output frequency is higher and this provides desirable control characteristics. In an alternative arrangement the machine 62 is driven by the traction motors. In a modified system (Fig. 2), the excitation of the generator 16 is controled in dependence upon the degree of slip in the motors 25. An auxiliary frequency converter machine 70 is mechanically coupled to the shaft of one of the traction motors and has its stator windings fed from the supply to the traction motors. The frequency of the output of the machine 70 is thus dependent upon the slip, and this output is applied to a hysteresis motor 71 normally acting as a synchronous motor to drive a direct-current tachometer generator 72. The field winding 52 of the exciter 50 is supplied from the generator 72 so as to tend to reduce the excitation of the generator 16 when the slip is too great. In order to prevent excessive speed of the tachometer generator 72 during starting or other transient conditions a centrifugal brake 74 is provided, the motor 71 stopping with a constant but limited torque when over-loaded.

The crank shafts are driven from the motors by toothed gearing involving bevel gears interconnecting the two sets of gearing. In operation the upper blade is set by the motor 16 and spindle 17 to rest on the slab. The motors then operate the crank shafts to cause levers 9 to move upwardly at their outer ends and lift the lower blade to effect shearing.

Title: Complementary field-effect type semiconductor device
Inventor: SATO TAI

Abstract: 1,261,494. Semi-conductor devices. TOKYO SHIBAURA ELECTRIC CO. Ltd. 26 Feb., 1970 [27 Feb., 1969 (3); 28 Feb., 1969 (2); 23 May, 1969], No. 9346/70. Heading H1K. Carrier mobility in both channel regions of a pair of complementary field-effect transistors in a diamond-structure or zinc blend-structure semi-conductor body is maximized by arranging the channels to be mutually perpendicular and to lie in selected crystallographic axis relative to the plane of the major face of the body. If the major face lies in a plane in the [100] zone (i.e. with its normal perpendicular to the [100] axis) and has its normal within 0‹ and 45‹, 45‹ exclusive, of the [011] axis, the N-channel lies along the [100] axis while the P-channel lies perpendicular thereto. If, however, the major face lies in a plane in the [011] zone there are two possibilities. Firstly, if the normal to the face is within 0‹ and 35‹ 15' of the [011] axis, the N-channel and P-channel lie respectively perpendicular and parallel to the [011] axis. Secondly, if the normal to the face is 35‹ 16' to 90‹ from the [011] axis, 90‹ exclusive, the N-channel and P-channel lie respectively parallel and perpendicular to the [011] axis. Further limitations on the plane of the major surface may be dictated by the need to minimize the surface state density. Thus, for planes in the [011] zone, the angle between the normal to the face and the [011] axis preferably lies between 48‹ 46' and 84‹ 16' while for planes in the [100] zone the angle between the normal to the face and the [011] axis preferably lies between 6‹ and 37‹ 20'. Semiconductor materials to which the invention is applicable include Si, Ge, semi-conducting diamond, GaAs, GaP and GaSb. The fieldeffect transistors may be of the insulated-gate, junction-gate or Schottky-barrier-gate types, and in the first mentioned case the gate insulation may comprise phosphorus-doped SiO 2  to improve stability, and the channel lengths of the complementary devices may differ. Fig. 7 shows a NAND-gate including four P-channel MOSFETs 42-45 in which adjacent devices share common source and drain regions 51-53. The gate electrodes 57-60 of the devices 42-45 are common to the gates of four perpendicularly aligned N-channel MOSFETs 46-49 sharing common N+ source and drain regions 55, 56 in an N-type region 41.
