Title: Abnormality detector for rotary electric machine
Inventor: KANEDA KICHIJI
IPC: G01R31/12
Filed: 1991-03-27
Abstract: PURPOSE:To always monitor abnormality in a stator coil high sensitively by detecting radiated electromagnetic waves based on the partial electrical discharge occurring together with the abnormality in the stator coil due to the electrostatic coupling occurring between the stator coil and an electrode. CONSTITUTION:While an electric generator 10 is operated, high voltage is generated in a stator coil 12. When abnormality occurs in the coil 12 during the operation of the generator, the high frequency current caused by the partial electrical discharge occurring in the coil 12 is propagated in the coil 12. This high frequency current is remarkably damped, but undamped current surely passes an end section 3 of the stator coil 12 within a range of one turn from the position where the electrical discharge occurs, and at this moment, electromagnetic waves are radiated to air from the end section 3. This radiated electromagnetic waves are detected by the cylindrical electrode 14 opposite to the end section 3 in the manner of electrostatic coupling and are led to an abnormality detector 20 to detect the abnormality. In the case of electrostatic coupling, the electromagnetic waves radiated from high frequency current is properly coupled with a high frequency signal, being detected sensitively in the range where the high frequency current based on partial electrical discharge does not damp.

Title: Home controller
Inventor: FUKUOKA ICHIRO
IPC: G06Q50/00
Filed: 1986-03-20
Abstract: PURPOSE:To inform a user that the storage contents are not normal by providing a backed-up code storage means to store the code showing a data writing mode and informing the abnormality of the written data while the code is stored in the storage means after the data is written. CONSTITUTION:A power supply is instantly turned off owing to a service interruption, etc., while a control means 2 is writing the data A received from a data input means 4 to a data storage means 6. Under such condition, the data A written before the power supply is turned off is stored in the memory 6 since the means 6 is backed up by a battery 11. Thus just a part of the data A to supplied is stored. Here a code C showing a data writing mode is delivered from a code generating means 7 and stored in a code storage means 8 via the means 2. A data abnormality informing means 10 checks whether or not the code C is stored continuously in the means 8 and displays the information showing that the power supply is turned off while the data A is written on a display means 1 as long as the code C is not reset.

Title: Optical control superconductive element
Inventor: HASEGAWA HARUHIRO
IPC: H01L39/22
Filed: 1987-03-20
Abstract: PURPOSE:To obtain an optical control superconductive element having high sensitivity and high speed optical response by providing a potential gradient to separate electron-hole pairs generated by light-irradiation without recombina tion, and increasing free carrier density. CONSTITUTION:A potential gradient is provided at a semiconductor for separat ing two superconductive electrodes, and carrier is effectively gathered at a channel in which a current in the semiconductor flows. That is, electron-hole pairs are generated at the time of irradiating a light, they are separated momen tarily by the provided potential gradient, and the separated electrons or holes are gathered in the channel in the semiconductor without recombination. Then, free carrier density of this region is increased, when it exceeds a predetermined threshold value, a superconductive current flows between superconductive electrodes 1 and 2, but the electrons and the holes are recombined upon interrup tion of the light to reduce the free carrier density. Accordingly, a superconduc tive current does not flow between the electrodes. Therefore, a semiconductor having small alleviating time can be used to perform a light control superconductive element having high sensitivity and high speed optical response.

Title: Reversal development type electrostatic recording device
Inventor: HASEGAWA YUJI
IPC: G03G15/22
Filed: 1986-03-20
Abstract: PURPOSE:To securely prevent toner from sticking unnecessary through simple constitution by operating an electrostatic charging means in an operation process, etc., which is not relevant directly to an electrostatic latent image forming process. CONSTITUTION:When a corotron 30 for electrostatic charging is turned on with a signal supplied from a CPU 104 to a high voltage unit 112, the surface of a rotating photosensitive drum is charged uniformly and positively. When the positively charged surface of the drum is positioned right below an LED head 28, all LED elements of the LED head 28 illuminate. Thus, the corotron 30 for electrostatic charging is turned on, and consequently even when the photosensitive drum surface which is not exposed to the LED head 28 passes right under a developing device, a repulsive force operates on toner which is charged positively because the drum surface is charged positively as well, so that no unnecessary toner is attracted to the photosensitive drum surface.
