Title: Inverter controller, inverter control method, recording medium, and program
Inventor: SATO EIJI
IPC: H02P6/28
Filed: 2001-10-23
Abstract: PROBLEM TO BE SOLVED: To adjust phase differences among carrier waves used in control of two inverter circuits, without outputting unexpected torque from a motor. SOLUTION: When the phase difference between the carrier waves of two inverter circuits INV1 and INV2 is adjusted from a state of 0 deg. to a state of 90 deg., the frequency of the carrier wave of the inverter circuit INV2 is controlled so as to be three-quarters the frequency of the carrier wave of the inverter circuit INV1 by one cycle. When the phase difference between the carrier waves of the two inverters INV1 and INV2 from a state of 90 deg. to a state of 0 deg., the frequency of the carrier wave of the inverter circuit INV2 is controlled so as to be three-quarters the frequency of the carrier wave of the inverter circuit INV1 by one cycle. Hereby, it is possible to adjust the phase difference between the carrier waves, while maintaining continuity of the carrier waves.  As a result, it is possible to prevent unexpected torque from being outputted from the motor, based on discontinuous carrier waves.

Filed: 2001-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a control signal part which has a structure reducing wire breaking and its manufacturing method, and a liquid crystal display including it and its manufacturing method. SOLUTION: A contact hole 270 which exposes a signal wire 220 is so formed that the length of a side bordering on the signal wire 220 is larger than the width of the signal wire 220. On the signal wire 220 exposed through this contact hole 270, a control signal auxiliary pad 280 is formed. Thus, the length of the side of the contact hole 270 is made larger than the width of the contact hole 270 to reduce the Joule's heat quantity due to a voltage drop at the border part between the contact hole and wire caused while static electricity accumulated in the wire is discharged, which is advantageous to prevent wire breaking.

Title: Transformer cooling method
Inventor: IWAMOTO MASATOSHI
IPC: H02B1/56
Filed: 2001-11-07
Abstract: PROBLEM TO BE SOLVED: To safely and efficiently cool a transformer to avoid its deterioration and extend its operation life. SOLUTION: It is difficult to control the temperature rise of a transformer which is used for a long time. As one of countermeasures for this problem, an expensive and large size amorphous transformer which has a smaller no-load loss than a conventional transformer is employed. However, sometimes an ambient temperature of an installation site itself may be high. This transformer cooling method includes a transformer, a thermosensor, a pressure fan, and a water-proof gallery which are provided as one set and are relatively expensive (in a receiving chamber, a transformer, a thermosensor, and a pressure fan are supplied as one set and one suction water-proof gallery and one exhaust water-proof gallery are separately provided, which save the cost to some extent) but the cost is substantially lower than the installation cost of the amorphous transformer. Further, by this method, the problem of the temperature rise of the transformer can be solved. The water-proof galleries may be used in ventilation (exhaust) equipment of a machine chamber and an electric chamber, in which energies such as a thermal power and an electric power, etc., are consumed. However, in such a case, galleries are simply replaced by weather covers and the weather covers are further simply replaced by the water-proof galleries, so that the concept is completely different from the concept of the former one and can not be the object of comparison.
