Title: Cathode material for electrolytic condenser
Inventor: TSUCHIYA TAKASHI
IPC: H01G9/04
Filed: 1988-10-27
Abstract: PURPOSE:To manufacture the title cathode material for electrolytic condenser in high electrostatic capacity and yet high reliability by a method wherein an evaporation film of a metallic boride is formed on the surface of a metallic substrate comprising a previously roughened aluminum foil. CONSTITUTION:In argon gas atmosphere at 10<-3>Torr, titanium boride 1000Angstrom  thick is evaporated on the surface of a previously roughened alumina foil 20mum thick.

Title: High speed re-closing path earthed switch
Inventor: NIHEI SHOZO
IPC: H01H33/91
Filed: 1992-10-09
Abstract: PURPOSE:To provide a high speed re-closing earthed switch capable of cutting off an induction current that cannot form a current zero point during several cycles. CONSTITUTION:A controller 23 for controlling a speed of a switch opening operation is disposed in an operating device 9 of a puffer type arc extinguishing chamber 7. The controller is such constituted that a speed of the switch opening operation is temporarily reduced from the vicinity of a first switch opening position where a pressure increasing value, at which an electromagnetic induction current can be cut off, can be obtained at the time of switch opening while a speed of the switch opening operation is increased after a second switch opening position in the final period of switch opening. For example, a buffer for decelerating the switch opening operation is used as the controller, and it can be operated at the time of deceleration while it can be stopped at the time of acceleration. The second switch opening position in the final period of switch opening can be particularly set near the switch opening position corresponding to the terminal point of a zero-miss current in the case where the zero-miss current is generated.

Title: Power consumption reduction circuit
Inventor: NISHIIE TAKAKO
IPC: H03K3/037
Filed: 1987-10-27
Abstract: PURPOSE:To reduce the power consumption by adopting the constitution such that a detection means of a change in a data signal is provided and a sampling signal supplied externally is used as a signal only when the change in the data signal is detected. CONSTITUTION:When a sampling signal (a) goes to a high level, nodes (f), (d) go to a low level and a node (e) goes to a high level to await a data change. When a data signal (b) is changed, since is given to a node (c) via a delay circuit 1, a high level pulse is outputted to the node (d), the node (e) changes to a low level and the node (f) goes to a high level. Thus, an R-S latch 3 is in the input state of a sampling signal and a master latch 7 reads the signal (b). When the signal (a) goes to a high level, the node (f) goes to a low level, the latch 7 is in latch state, a slave latch 8 reads data, and an output Q of a D FF comprising latches 7, 8 and an inverter 6 outputs data. Thus, even when the signal (a) changes, so long as the signal (b) is unchanged, since the sampling signal of the latches 7, 8 is unchanged, the power consumption is reduced.
