Title: Manufacture of directly-heated impregnated cathode
Inventor: KOBAYASHI KAZUO
IPC: H01J9/04
Filed: 1986-01-14
Abstract: PURPOSE:To enable the reduction in the cost of a directly-heated impregnated cathode and the mass production thereof, by winding a molybdenum wire on a molybdenum mandrel, filling a high-melting-point porous metal powder around the wire, sintering the powder, and thereafter dissolving the mandrel and the wire to remove them. CONSTITUTION:A molybdenum wire 22 is wound at a prescribed pitch on the peripheral surface of a molybdenum mandrel 21. A powder 23 of tungsten or the like is filled around the wire 22 and sintered to have a void ratio of 15-20%. After the peripheral surface of the sintered material is cut, the assembly of the mandrel 21, the wire 22 and the sintered material is immersed in a mixed solution of nitric acid, sulfuric acid and pure water to dissolve the mandrel and the wire to remove them to obtain a helical porous piece 24 of the tungsten or the like. An electron emission substance is impregnated into the pores of the piece 24. The surface of the piece 24 is then polished, thus manufacturing a directly-heated impregnated cathode. For these reasons, the helical piece 24 is prevented from being broken in processing, the cost of the electrode is reduced and the mass-producing property thereof is enhanced.

Title: Driver for dc motors
Inventor: KOGA TAKESHI
IPC: H02H7/08
Filed: 1978-01-24
Abstract: PURPOSE: To reduce the breaking duty of a high-speed circuit breaker, by changing the connection of the high-speed circuit breaker and cutting off the field current of a main motor to decrease the current of the main motor.  
     CONSTITUTION: Armatures M1, M2 are cross-connected to field windings F1, F2. The high-speed circuit breaker HB added with no current-decreasing resistor is connected in series with one main motor. When a chopper CH1 or CH2 fails in commutation during regenerative braking, the high-speed circuit breaker HB is opened first. After a predetermined time, a circuit breaker L1 is opened in connection with the opening of the high-speed circuit breaker HB. Since the high-speed  circuit breaker is provided in a circuit wherein the main motors are connected in  parallel with each other, the circuit can be easily opened. Thereafter, because the  main motors have a crossfield circuit, the current of the other main motor decreases sharply due to the loss of the field current.
