Title: Electromagnetic switch
Inventor: KAJINO SADAYOSHI
IPC: H01H50/36
Filed: 1991-12-24
Abstract: PURPOSE:To reduce magnetic resistance while restraining an increase in physical weight or raw materials. CONSTITUTION:A coil case (yoke) 3 and a plunger 7 constitute a gap possessing closed magnetic circuit interlinked to coils 51 and 52 together with the other soft magnetic members, and when an electric current is supplied to the coils 51 and 52, the plunger 7 is moved in the axial direction, and is sucked in the axial direction. An internal cylinder part 32 extended coaxially with the plunger 7 to the coil side from the inner peripheral edge of an edge plate part 31 of the coil case 3, is opposed to the outer peripheral surface of the plunger 7 through a gap, so that magnetic resistance of the gap between the coil case 3 and the plunger 7 can be reduced significantly. As a result, an electric current supplied to the coils, cross sectional areas of the coils, or the number of turns of the coils can be reduced, so that electric power consumption or raw materials can be reduced. Since the internal cylinder part 32 can be manufactured by means of a press working of the coil case 3, the manday is never increased.

Title: Semiconductor relay circuit
Inventor: YAMAGUCHI SHUICHIRO
IPC: H03K17/08
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To provide a relay circuit preventing excess current from continuing to flow to the load side. SOLUTION: Because thyristors 8a and 8b are in interruption states when negative excess current is small, conducting is performed between output terminals O1 and O2. When negative excess current is large, the voltage generated at the both ends of the resistances 7a and 7b for detection of negative excess current is increased. When this voltage exceeds the voltage operating the thyristors 8a and 8b, current flows from the anodes A of the thyristors 8a and 8b to cathodes C. As a result, the voltage between the gates G of MOSFET 3a and 3b for output and a source S is lowered and the current flowing in the MOSFET 3a and 3b is interrupted.  Because the current flowing from the anodes of the thyristors 8a and 8b to the cathodes C flows even after the current from the gates G of the MOSFET 3a and 3b is eliminated, the voltage between the gate G of the MOSFET 3a and 3b and the source S is remained low even after negative excess current is interrupted.

Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To obtain a defect-cell repairing circuit capable of executing a defect- cell addressing program through the external terminals of a memory device even after it is sealed. SOLUTION: Inputting a predetermined signal from a control terminal, a repair-mode enabling circuit 100 generates a repair-mode enabling signal ϕMI to operate thereby a repair-mode decoder 200. The decoder 200 decodes repair- mode signals PMi inputted to its address terminals to generate repair-mode selecting signals ϕRMi. A fuse controlling circuit 300 combines logically fuse selecting signals PAi inputted to its address terminals with the inputted repair- mode selecting signals ϕ RMi to make its fuses blow and generate programmed address signals in response to the states of its respective fuses, and compares the programmed address signals with its address signals Ai inputted by its ordinary operation to generate a redundancy enabling signal ϕRE when the compared signals coincide with each other.  Since the repair mode can be executed using the control terminals and address terminals of a memory, the memory device is made repairable even in its packaged-off state.
