Inventor: DONALD STIMSON BECHUUN
IPC: H01L29/76
Filed: 1999-11-11
Abstract: PROBLEM TO BE SOLVED: To avoid fluctuation in a Coulomb barrier by applying a voltage between a source/drain region and a gate and receiving one electron from the source/drain region or a channel region for accumulating for the cage molecule of an insulation material layer.

Title: Transfer device
Inventor: YAMAGUCHI CHISEKI
IPC: G03G15/16
Filed: 1991-11-09
Abstract: PURPOSE:To improve the safety and the handleability by arranging a conducive fiber-like member opposite to an electrostatic latent image forming body, with a gap interposed, so as not to be in contact with a recording form, and opposite to an intermediate transfer body, with the gap interposed, on the rear side of the intermediate transfer body. CONSTITUTION:A conductive fiber-like member 3 is made into a roll, against a metallic shaft 12, and an insulation gap maintaining roller 14 maintaining the gap G between the electrostatic latent image forming body (photosensitive body) 5 and the surface of the conductive fiber-like member 3, is attached to both sides of the metallic shaft 12, in a state where the roller 14 is pressed against the photosensitive body 5. On the other hand, a power source for a transfer 4 is connected to the metallic shaft 12. Then, the insulation gap maintaining roller 14 and the metallic shaft 12 are rotated by interlocking to the rotation of the photosensitive body 5, and the conductive fiber-like member 3 is integrally rotated, as well, so that the surface of the member 3 is always changed, a transfer electric field can be stably formed, and an applied voltage can be fairly lowered in an absolute value, as well. Thus, the safety and handleability can be improved.

Title: Image sensor driving method
Inventor: KANO MITSUNARI
IPC: G06T1/00
Filed: 1987-12-21
Abstract: PURPOSE:To prevent a noise from being superimposed on a sensor output by inputting seizing signals to all the image sensor chips first and successively inputting a shift clock only to an image sensor chip selected so as to output a picture signal. CONSTITUTION:Seizing signals S1-S3 are simultaneously added to all the chips in the first timing of a driving. After that, while the shift clocks (a C1 continuous line part) proportional to the number of picture elements outputted from a chip 1 are given to the chip 1, the clocks of the other chips are kept stopped. When the output of a second chip is to be obtained, the shift clocks of the first chip and a third chip are stopped, and only the shift clocks of the second chip (a C2 continuous line part) are added. After the adding of the shift clocks of the third chip is completed in this manner, residual charges in a CCD are discharged by simultaneously adding shift clocks C'1, C'2, and C'3 to the chips 1-3 as needed. Thus, bad influence in which a driving signal ununiformly generates an offset in the picture signal, etc., can be eliminated, and picture quality can be improved.

Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To effectively make use of a voltage compensator which becomes impossible of control by extension of power supply, in an AC electric railway using a Scott transformer. SOLUTION: An inverter device (SVG) 3 is connected to the T seat and M seat of a Scott transformer 1A, and at normal time when the load of return feeders 2T and 2M from the Scoff transformer 1A, the control of the inverters 3T and 3M is made by equalizing the active power by detecting active power and reactive power of each seat, and compensating the reactive power on load side by voltage control of an inverter, and circulating half the difference of the active power of each seat by frequency control of an inverter.  At the time of extended power supply which supplies power from the Scott transformer 1B to load, the supplementation control of reactive power is performed from the seat whose voltage is higher than the specified voltage to the seat whose voltage is lower than it by the frequency control of the inverter, detecting the voltage of each seat, because the detection of power can not made, and the voltage compensation control of the seat whose voltage is lower than it is performed by the control of supply of reactive power by voltage control. In the case that both seats are at specified voltage or under, only the voltage compensation control is performed.
