Title: Forcible discharging circuit for multiple power supply
Inventor: KAWANISHI KUNIHIKO
IPC: G05F1/56
Filed: 1983-06-30
Abstract: PURPOSE:To avoid a malfunction of a load circuit by adding a forcible discharging circuit between two DC voltage output terminals. CONSTITUTION:The secondary power supplies (+5V and -5V) are obtained from a primary power supply AC through a multiple power supply circuit 1 and supplied to load circuits Z1-Z3. A forcible discharging circuit N is connected between output terminals of the circuit 1. Then a current is supplied if a difference is produced between the positive and negative secondary discharge voltages when the power supply AC is cut off. For the circuit N, a series circuit of a Zener diode D1 and a resistance R2 is connected between terminals of the secondary voltages together with a base-collector circuit of a transistor TR1 connected between both ends of the R2. The current of the TR1 is cut off in a normal operation mode, and the base of the TR1 is inverted to a negative potential when the +5V side has a drop first with the break of the power supply AC. Thus the TR1 is turned on and discharged forcibly.

Title: Wiring for electronic circuit
Inventor: NAKAI YUTAKA
IPC: G02F1/1362
Filed: 1992-05-13
Abstract: PURPOSE:To reduce a parasitic capacitance while maintaining electrical connection by removing an inside of one conductor film in advance when irradiating laser to conductor films which are arranged in superposition. CONSTITUTION:A conductor film 201, an insulation film 204, a conductor film 202 whose inside of a laser beam irradiation part is removed and a passivation film 205 are formed on a substrate 203. Liquid crystal is sealed on the passivation film 205 viewed from the substrate 203. When a laser beam is applied from a direction E, the conductor film 210 absorbs the energy, is heated rapidly and liquefied or gasified to expand its volume. As a result, the insulation film 204 and the passivation film 205 are broken through, a liquid layer of the conductor film 201 adheres to a periphery of a hole made by the laser irradiation and an electrical contact with the conductor film 202 is realized. Since the area of superposition of a laser contact part is reduced, it is possible to restrain an element from deteriorating by reducing the parasitic capacitance and to restrain change of element characteristic before and after repair.

Title: Nonlinear resistive element by superconductor
Inventor: TSUKADA KEIJI
IPC: G01R29/08
Filed: 1992-04-15
Abstract: PURPOSE:To set the critical current value of a bridge to several mu A to several mA and respond to electromagnetic waves from several 10Hz to several MHz by setting the sectional area of a superconductive wire to a specified value or less and the length to a specified value or more. CONSTITUTION:A superconductor 11 and a superconductor 11 are coupled by a fine superconductive wire 0.1mum<2> or less in sectional area and 10mum or more in length. The maximum value of a current flowing in the superconductive wire, that is, the critical current value increases together with the sectional area of the superconductive wire. Accordingly, a critical current from several muA to several mA can be gotten by setting the sectional area of a bridge 12 to 0.1mum<2> or less. Moreover, the Josephson effect can be eliminated by enlarging the length of the bridge 12 to more than 10mum above the length of coherence. Furthermore, since the quasiparticles inside the bridge 12 resonate with the electromagnetic waves applied from outside and work to decrease the superconductive current, the resistance property of the bridge 12 can be changed by the low electromagnetic waves from several 10Hz to several MHz.
