Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To disconnect a ground fault section quickly and to recover the sound section in the upstream thereof by providing means for opening a section switch before a circuit breaker is reclosed upon decision of fault in its own section. SOLUTION: A backup power supply 24 is operated during power interruption based on the ground fault of a distribution line 4 and when a decision is made that if its own section is faulty based on the measurements of a sensor 17, overcurrent information is stored in its own section and not stored in the adjacent section on the load side. A decision is made whether its own section is faulty or not based on the combination of presence and absence of overcurrent information for both sections through communication with a switch controller 15 between adjacent sections on the load side. If its own section is faulty, the section switch 14 of the relevant section is opened before the circuit breaker 3 in a substation 1 is reclosed to disconnect the faulty section, and the sound section in the upstream is recovered quickly when the circuit breaker 3 is reclosed.  This system eliminates a large scale base station facility or a communication facility.

Title: Electromagnetic clutch controlling device for car
Inventor: SAKAKIYAMA RIYUUZOU
IPC: B60W10/10
Filed: 1984-01-30
Abstract: PURPOSE:To obtain sufficient and adequit engine brake effect by reducing the clutch-released car speed in a Ds range compared with that in a D range and extending the directly connecting area of a clutch in said Ds range toward a low car speed side. CONSTITUTION:When a Ds range is selected, a Ds-range switch 51 is turned on and a voltage dividing circuit is earthed midway, reducing a reference voltage. Thereby, a clutch-engaged car speed V1H and a clutch-released car speed V1L, which operate equally as in the case of the D range, are moved uniformly to the low car speed side. Thus, an effect due to hysteresis similar to one in the case of the D range can be obtained while the clutch-released car speed V1L is reduced, extending a directly connecting area toward a low car speed side. Accordingly, an engine brake works sufficiently to a low car speed.

Title: Electric water boiler
Inventor: KOBAYASHI HIDEAKI
IPC: A47J31/00
Filed: 1989-01-25
Abstract: PURPOSE:To invariably feed a fixed quantity of hot water by detecting the water level of a fixed-quantity tank with a water level detecting section, stopping a pump, and opening an opening/closing valve with a driving section to drip hot water. CONSTITUTION:A pump 37 is operated and a solenoid 48 is excited by a control circuit 52, and a pouring out port 45 is closed by an opening/closing valve 47 via a lever 46. Hot water is guided to a fixed-quantity tank 39 in sequence by the pump 37 to raise the water level. A float 41 in a water level pipe 40 is raised and enters between the photo-diode 42 and the photo-transistor 43 of a water level detecting section 44 and shields the light. The control circuit 52 stops the operation of the pump 37 based on this light shield signal and concurrently cuts off the excitation of the solenoid 48. The suction force of the solenoid 48 is lost, thus the lever 46 is rotated counterclockwise by the spring force of an exciting spring 49, and the opening/closing valve 47 opens the pouring out port 45. As a result, hot water in the fixed-quantity tank 39 flows out to a drip section 50 and drips into a basket 57 through a dripping port 51.

Title: Magneto-resistance effect type head
Inventor: KANAI HITOSHI
IPC: G11B5/39
Filed: 1994-02-09
Abstract: PURPOSE:To set directions of magnetization opposite in a signal detection region and to prevent fluctuation output by reducing the thickness of the intermediate film between an MR film and a bias film and acting antiferromagnetic bond between the MR film and the bias film. CONSTITUTION:The magnetization of the MR film 3 and the magnetization of the bias film 1 are magnetostatically coupled to each other in a direction (y). The magnetization of the MR film 3 is inclined by receiving a bias magnetic field from the bias film 1 in such a manner that the resistance (electric resistance) of the MR film 3 changes linearly with respect to the signal magnetic field from a recording medium. The thickness of the intermediate film 2 is set sufficiently small in such a manner that the magnetization of the MR film 3 and the magnetization of the bias film 1 make antiferromagnetic coupling via the intermediate film. In such a case, the antiferromagnetic coupling arises between the MR film 3 and the bias film 1 and the magnetization of both films is stably made into the opposite state. The fluctuation in the output of the MR head is thus prevented.
