Patent JP-S59156019-A (JP)
Title: Interface circuit
Inventor: IMAMURA MAKOTO
IPC: H03M1/40
Filed: 1983-02-25
Abstract: PURPOSE:To attain ease of circuit integration by designing the circuit so that an offset (or threshold voltage) of an inverse amplifier and a capacitance of a capacitors do not give principally effect on the accuracy of an output so as to reduce number of highly accurate components. CONSTITUTION:In a main circuit 30, switches S32, S36 alone are turned on at first, then only S33, S37 are turned on, then only S32, S36 are turned on, then only S34, S35 are turned on and further an S31 is turned on. The inverse amplifier A acts like a comparator in this case, and when a Va is larger than its offset voltage VT, that is, when the relation of VIN<VR/2 exists, an output V0 goes to L, and when the relation is converse, the output V0 goes to H and a 1-bit A/D converting output is obtained. When only the S35 is turned on with VIN<VR/2, a 2VIN of residue output is obtained. In case of VIN>=VR/2, only the S33, S37 are turned on at first, then only the S31, S37 are turned on, the only the S33, S36 are turned on and then only the S34, S35 are turned on. A 2VIN-VR of residue output is obtained in this case.

Title: Installation of lightening arrester in transmission system
Inventor: NAKAMURA TAKAO
IPC: H02H6/00
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To shorten the length of an insulation device by determining such an installation position as the restraint of switching surge is effective at a simulation test, and installing a gap-less lightening arrester on the insulation device at the determined position for restraint of the swithcing surge. SOLUTION: The length of a prescribed transmission line is divided into 100 equal parts. A gap-less lightening arrester is fitted between the (n)th-divided point (n=1, 2 to 100) of the transmission line and the ground point, and is connected to the divided point of n=1 from an electric power source through a coil L and a switch. The switch is turned on or off to apply switching surge to the transmission line. In installing an electricity protection insulator on an insulation set disposed in the transmission line, an installation position is determined, which causes the restraint of the switching surge to be effective at simulation test, and the gap-less lightening arrester is installed on the insulation device positioned at the determined insulation to restrain switching surge. It is thus possible to shorten the length of the insulation device.
