Filed: 1977-11-08
Abstract: PURPOSE: To enable application of reverse bias voltage to thyristor always as required regardless of the load variations by applying the gate reverse bias voltage at timing when the thyristor anode becomes zero.  
     CONSTITUTION: The gate trigger current Ig of a thyristor 32 turns off itself to allow the voltage VL of a resonance inductance 35 to become zero when it is changed from negative to positive at zero voltage crossing time. Reverse bias boltage is applied between the gate and the cathode when the anode current of the thyristor becomes zero to cause the voltage VF to cross the zero voltage. In such a gate trigger type, the applying timing of the gate reverse bias can be set regardless of the load variation.

Title: Raised wiping sheet, its manufacture, and cleaning article using the wiping sheet
Inventor: TAKEUCHI NAOTO
IPC: D04H1/495
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To raise the bulk of wiping sheet and to improve its touch on the skin by raising through partially cutting and disentangling fibers from the surface of nonwoven fabric formed by adhesion or interlacing of fibers. SOLUTION: Ends of fibers are made further protruded from the surface of nonwoven fabric 1 by giving resistance on the surface of the nonwoven fabric 1 to partially cut fibers and by partially disentangling interlacing of fibers. By this process many more fibers' ends are protruding from the nonwoven fabric 1 comparing with the state in which raising has not been done. That is, a large amount of raised fibers 3 exist. Further, after raising, the thickness of the nonwoven fabric 1 itself becomes thick and its bulk is raised. Thus, since being raised, the wiping sheet has a high bulk and its touch on the skin is excellent.
