Title: Delay circuit
Inventor: TORII SHIYUUICHI
IPC: H03K17/28
Filed: 1984-02-20
Abstract: PURPOSE:To constitute a delay circuit with a semiconductor IC by accumulating periodically the electric charge to a capacitor and at the same time shifting periodically the accumulated charge to other capacitors and by making use of the time during which the voltage obtained from said accumulated charge reaches its prescribed level. CONSTITUTION:When a clock pulse phi is set at a reference level with a timing circuit 1, an MISFETQ1 is turned on and a capacitor C1 is charged up to the power supply voltage. Then the pulse phi varied to the power supply voltage level. Thus the FETQ1 is turned off and at the same time an MISFETQ2 is turned on, and the electric charge accumulated at the capacitor C1 is dispersed to a capacitor C2. The electric charge of the C2 increases gradually with repetition of the clock pulse. An inverse MISFETQ7 is turned on when the output voltage VC2 reaches the threshold value of the FETQ7 of an FF circuit 2. Then a clear signal ACL, i.e., the output of the circuit 2 is inverted to perform the clear release. It is possible to use the time during which a power supply is applied and the VC2 of C2 reaches the threshold value of the Q7 as a delay time.

IPC: H01L21/322
Filed: 1993-02-18
Abstract: PURPOSE:To increase the speed of a semiconductor substrate provided with both power IC and its control circuit by controlling the life time of only the power IC. CONSTITUTION:The prescribed impurity atom concentration is relatively increased previously in a selective area 3 in which the carrier recombination life is to be shortened for a semiconductor substrate 1. Then, charged particle beams are applied on the whole plane of the semiconductor substrate 1 so as to selectively increase the density of a specific defective level in the selective area 3 and the selective area 3 is changed as an area for shortening the recombination life. Since the area whose carrier life is desired to be shortened can be selectively formed in the semiconductor substrate as a solid area, the area whose carrier life is desired to be shortened can be formed only on the power IC and the speed can be increased without influencing the control circuit even the semiconductor substrate is provided with both power IC and its control circuit.

Abstract: PROBLEM TO BE SOLVED: To prevent over current in a transformer in which an exciting rush current and a ground current are superimposed, by opening an AC circuit breaker and at least any one of first and second contactors depending on a detected value of grounded relay for detecting a current flowing from one end of DC side of single phase converter to the ground. SOLUTION: When ground accident is generated between a secondary coil 5 and a second contactor 7, a ground relay 53 detects a ground current to open an AC circuit breaker 2 and first and second contractor 9, 7. Then, a ground current is cut out. Thereafter, when operation is started again under the condition that the grounded area is not yet removed, an AC circuit breaker 2 is turned ON. In this timing, the secondary coil 5 of the transformer 3 is not yet turned on by the first and second contractors to maintain the open condition. Only an exciting rush current flows to the primary coil of the transformer 3. Thereafter, when the first contactor 9 is turned on, a ground current flows again in the same path and the second coil is grounded but the rush current is attenuated to disappear and therefore it does not flow simultaneously with the short-circuit current.
