Title: Short-circuit protector of 3-level power converter
Inventor: DOBASHI HIDEYOSHI
IPC: H02M7/483
Filed: 1996-08-15
Abstract: PROBLEM TO BE SOLVED: To protect IGBT's(insulated gate bipolar transistors) of which a power converter outputting voltage of 3 levels, i.e., positive, negative and zero, from an overcurrent caused by a short-circuit, etc. SOLUTION: IGBT's 1a-1d are turned on and off by a gate controller 6 through gate drivers 2a-2d. When a short-circuit failure is detected by a short- circuit detector in the gate driver (2a, 2b, 2c or 2d), if the fact is transmitted to the gate controller 6 through a signal line (5a, 5b, 5c or 5d), the gate controller 6 controls an order in which the gate drivers are put into protective operations through a logic circuit 6A so as to avoid a prohibiting mode. With this constitution, the IGBT's are protected from excessive voltage burdens.

Title: Electronic filing device
Inventor: OKU YOSHITAKA
IPC: G06F21/62
Filed: 1990-08-17
Abstract: PURPOSE:To improve the secret holing performance by ciphering the data themselves that are recorded into an external storage. CONSTITUTION:A data processor DP 11 produces the digital data including the image data, etc., which are stored in an external storage EM 12. A ciphering means MD 13 ciphers these digital data with a due command. The DP 11 records the digital data ciphered by the MD 13 into the EM 12. Thus the digital data can be automatically ciphered and recorded into the EM 12 by the DP 11 and the MD 13 respectively with no consciousness of ciphering required to a user. Thus it is impossible to understand the contents of the EM 12 unless the deciphering method is unknown even though the contents of the EM 12 are illicitly drawn out as long as the data themselves to be recorded into the EM 12 are ciphered.

Title: Standby operation method for gas turbine fuel gas compressor
Inventor: KUROEDA KOUJI
IPC: F02C9/40
Filed: 1997-08-11
Abstract: PROBLEM TO BE SOLVED: To suppress a fuel gas pressure rise of the suction side of a compressor to such pressure or more as causing the deficiency of facilities in the standby operation of the compressor by detecting the fuel gas pressure change of a compressor discharge side, and controlling the opening of a pressure adjustment valve through a predetermined program. SOLUTION: In the case of the supply of pressurized fuel gas from a fuel gas compressor 1 to a gas turbine 2, the temperature rise of the fuel gas in the standby operation of the compressor 1 lags behind pressure rise, and further pressure rise resulting from the lag causes the deficiency of the compressor 1. When discharge side fuel gas pressure is taken as Pd max determined by suction side fuel gas pressure Ps max permissible to the compressor 1 and this time discharge side fuel gas temperature is taken as Ts max, the opening of a pressure adjustment valve 8 is controlled based on a program function when fuel gas pressure rises and reaches Pd max in the standby operation, and thereafter the pressure adjustment valve 8 is fully closed when the discharge side fuel gas temperature reaches Ts max.

Title: Coin distributor
Inventor: MIYAZAWA KENICHI
IPC: G07F1/04
Filed: 1987-09-01
Abstract: PURPOSE: To surely exclude the coins staying on a flapper by stopping temporarily the flapper at its open position and then keeping this stop state for a prescribed time. CONSTITUTION: A storage motor starts via a storage flapper start key, and a storage flapper 5 starts to open toward its open position. When a storage flapper open sensor 17 detects the shading of light, the revolution of the storage motor is stopped. Thus, the flapper 5 stops at a prescribed open position. A timer starts its operation concurrently with stoppage of the storage motor. When the count value of the timer reaches a prescribed level, the drive of the storage motor is started again. As a result, the flapper 5 is kept inactive at an open position for a prescribed time. Thus, all coins remaining at a temporary holding part 16 drop and are stored in a coin storage box.

Abstract: PURPOSE:To increase the coupling strength between a cylinder for underground pile and the ground by a method in which when the cylinder for underground pile is lowered again, it is lowered integrally with an earth auger in such a way that a solidifying agent is pushed outwards by the cylinder and the earth auger. CONSTITUTION:The ground is excavated by an earth auger 2, during which period a cylinder 1 for underground pile is penetrated to a given depth into the ground. The cylinder 1 and the auger 2 are both drawn out and a solidifying agent 4 is injected into the hole so formed when drawing them out. The cylinder 1 and the auger 2 are both lowered into the hole with the agent 4 while operating the cylinder 1 and the auger 2 in a piston-like manner to press the agent 4, thereby strongly pushing out the agent 4. The coupling strength between the cylinder 1 and the ground can thus be sufficiently increased.
