Title: Faulty section isolating system for distribution line
Inventor: ISHIGURO TAKASHI
IPC: H02H7/26
Filed: 1991-09-17
Abstract: PURPOSE:To eliminate service interruption in the sound sections closer to the power supply than a faulty section by individually deciding a faulty section based on a signal fed from a section controller for sectioning the power supply and the load side and opening a section switch when a device sections a faulty section thereby isolating only the faulty section.

Controllers 11-14 have fault detecting functions similar to that of the substation 1 or functions for detecting a load side fault earlier. When a decision is made that the section switch is sectioning a fault section, the section switches 3-6 are opened and 'close prohibition' is stored. According to the system, faulty section can be isolated without causing service interruption in power supply side sound sections.

Title: Signal superimposing circuit
Inventor: SAITO TOSHIO
IPC: H04J1/00
Filed: 1985-11-26
Abstract: PURPOSE:To decrease the circuit scale and power consumption without increasing the amplitude of a superimposing signal by providing a current source comprising a transistor (TR) in place of a resistor deciding an idling current of an emitter follower circuit and using the superimposing signal so as to drive the current source TR. CONSTITUTION:A TR 9 acts like an emitter follower form and a signal to be superimposed from a signal source 1 is given to an output terminal 1 through an output impedance deciding resistor 10. On the other hand, a TR 11 uses resistors 7, 8 and 12 and acts like a constant current source. In applying the superimposing signal of a signal source 2 to a base of the TR 11, the current value of the constant current source is changed slightly by the signal amplitude and the result appears as a change in the output voltage and the amplitude of the signal source 2 is superimposed on said signal source 1. In changing the selection of the resistors 12 and 10 in this case, the transmission from the signal source 2 to an output terminal 14 is selected in a direction to increase the gain. Thus, no large amplitude is required for the signal source 2.

Title: Power supply control circuit
Inventor: MIYAZAKI SADAO
IPC: G06F1/00
Filed: 1985-11-26
Abstract: PURPOSE:To improve the reliability of a power supply control circuit by energizing an interface part only in a waiting mode for application of a power supply and therefore attaining the reduction of power consumption as well as the reduction of wear of parts. CONSTITUTION:The power is supplied to an interface power supply part 9 by the make of a primary power supply switch 1 and an interface part 3 conducts. Other circuit component parts, however, are not energized. Then the part 3 transmits the power supply signal to a power supply switch control part 8 with input of the power supply make signal of a control panel or the external control signal. The part 8 supplies the power to a fan 6, a sequence processing pat 4, etc. by the power supply signal. The part 4 starts automatically with supply of power and sends the start signal to a power supply unit 7. As a result, only an interface part 9 is energized in a waiting mode for make of the power supply of a power supply control circuit. While no power is supplied to other circuit component parts. This attains the reduction of both the power consumption and the wear of parts and improves the reliability of the power supply control circuit.
