Title: Gas insulated switchgear
Inventor: YASUE KAZUAKI
IPC: H02B13/02
Filed: 1993-12-28
Abstract: PURPOSE:To provide a gas insulated switchgear the size of which can be reduced by modifying the arrangement or the constitution of compositional members. CONSTITUTION:In a gas insulated switchgear where first and second main buses 1, 2 are split into four interconnected buses, the bus section lines BS1, BS2 connecting the split buses and the lines BCa, BCb linking the first and second buses are constituted as two sets of continuous lines arranged perpendicularly to the axis in the center of the main bus. This structure saves the width of gas insulated switchgear in the direction of main buses 1, 2 thus realizing reduction in the installation space. When the bus section lines and the bus linking lines are arranged while utilizing the space between the machines effectively, the gas insulated switchgear can be reduced in size.

Title: Starting device for diesel engine
Inventor: YAMA HAJIME
IPC: F02N11/08
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To prevent the suction coil of an engine suspension solenoid from being damaged by fire even when it takes time to start engine revolution, and dissolve faulty starting caused by the cold starting of an engine, or the delay of the suspension release of the engine suspension solenoid. SOLUTION: A timer circuit 17 is adapted to a control means 4, and concurrently a relay circuit 10 is provided for a suction circuit 5b. Based on the detection of the progress for the starting time T of an engine suspension solenoid 2 by the aforesaid timer circuit 17, before the engine revolution arrives at a starting engine revolution N after an engine has been started, the relay circuit 10 is turned off via a control means 4 so as to allow the suction circuit 5b to be isolated, and a suction coil 22 is thereby prevented from being damaged by fire. Energizing a starter 7 is still continued until the engine revolution arrives at the starting engine revolution N, and faulty starting is thereby dissolved, which is caused by the delay of the suspension release of the engine suspension solenoid.

Title: Storage device and underflow processing method
Inventor: HARUMOTO HIDEAKI
IPC: G06F5/06
Filed: 1990-11-30
Abstract: PURPOSE:To reduce the overhead for operating system(OS) operation and to speed up processing by forming saving addresses for data saved to a secondary storage area in a storage block. CONSTITUTION:When data 2b generates a write request to a storage block 1a, a mechanism MMU for calculating a saving address calculates the saving address and ejected data 2a are saved in the secondary storage area 3. At that time, a saving address 6 written in a saving address storing area 5 in the storage block 1a are also saved in the secondary storage area 3 as a part of the data. The storage address 6 of the data 2a is stored in the area 5 of a storage block 1 to generate an underflow by popping the block 1. Consequently the overhead for the OS operation can be reduced and underflow processing can rapidly be executed.

IPC: B64G1/36
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To realize uniform measurement and improve sensor performance by forming an electrode having a comb-like part on a solar light incident face of a pair of juxtaposed light detectors and placing a slit of a mask plate with respect to the incident face. SOLUTION: Light detectors 10, 11 formed with a solar light incident face in an approximate trapezoid are juxtaposed so that hypotenuses of the solar light incident faces face each other. Electrodes 12, 13 having comb-like parts 12a, 13a are formed on peripheries of the incident faces. Thus the solar incident faces are set with an entirely uniform resistance value. A slit 3a of a mask plate 3 is oppositely placed over the light detectors 10, 11 at a predetermined distance so that they cross with the slit 3a. When solar light passes through the slit 3a and is incident to the solar light incident faces entirely having a uniform resistance value to form a solar image 4, the light detectors 10, 11 output A, B outputs to a signal processing part 5 according to an image formed position.  The signal processing part 5 calculates a solar angle signal C based on the outputs, so that a solar direction can be detected highly accurately without being influenced by incident positions.
