Title: Thin-film field-effect transistor and manufacture thereof
Inventor: ANDO DAIZO
IPC: H01L27/12
Filed: 1985-02-14
Abstract: PURPOSE:To reduce leakage currents while decreasing the wirings of source electrode wirings and drain electrode wirings by burying a thin-film field-effect transistor section except source and drain electrodes into a light-transmitting insulating film. CONSTITUTION:A gate electrode 2, a gate insulating film 3, a semiconductor thin-board 4 and a passivation film 5 are deposited on a light-transmitting insulating substrate 1. A photosensitive resin film 9 is formed selectively, and the passivation film 5, the semiconductor thin-film 4, the gate insulating film 3 and the gate electrode 2 are wet-etched in succession while using the film 9 as a mask. An silicon nitride film 8 is deposited while leaving the photosensitive resin film 9 and lifted off, the passivation film 5 is etched selectively and a contact hole is bored, ITO is applied and shaped onto the whole surface, and a source electrode 6 and a drain electrode 7 are formed through selective etching. Accordingly, no stepped section is generated even when the gate electrode is thickened and the insulating film is thinned, thus preventing the disconnection of source-drain electrode wirings.

Abstract: PURPOSE: To make the degradation of image quality obsolete and make possible the freedom from maintenance by providing an elastic material scraper plate in the direction opposite from the moving direction of a developer support means and in contact with the surface of the support means.  
     CONSTITUTION: A scraper plate 5 which is fixed by means of a support member 6 in the direction opposite from the turning direction of a sleeve through utilization of its elasticity is so disposed as to position in a hopper 3 and exist in the front position of a thickness defining plate 7. This scraper plate 5 is provided with multiple window holes to permit falling of the scraped toner into the hopper and its reuse. Thereby, the toner particles having firmly stuck on the sleeve 2 may be forcefully removed and the supply of the toner having become larger in grain size to development is obviated, thus the degradation in image quality may be prevented.

Title: Manufacture of semiconductor device
Inventor: YASUDA YASUMICHI
IPC: H01L21/56
Filed: 1978-03-08
Abstract: PURPOSE: To increase the reliability of the device characteristics by avoiding the attachment of the unnecessary glass and also removing the extra glass when the glass powder is sticked onto the surface of the Si substrate via the migration method.  
     CONSTITUTION: Si substrate 3 and opposite electrode 4 are set into the adjusted migration solution 2, and then the DC voltage is applied to make the glass particle migrate to substrate 3. Thus, the glass particle sticks selectively to the mesa groove of the substrate. Then the substrate is taken out of the solution and then immediately soaked into the 1st cleansing solution, and thus the glass fine grain flowing on the SiO 2  mask on the substrate disperses into the 1st cleansing solution featuring a larger specific inductivity than the migration solution and thus with no sticking of the unnecessary glass. The 1st cleansing solution includes acetone, methanol and the like. After this, the substrate is soaked into the 2nd cleansing solution of xylene, trichloroethylene and the like featuring a smallest specific inductitity than the migration solution. Thus, the glass particle condenses in the solution of a small specific inductivity to be then condensed to the glass layer of the mesa groove or precipitated. Thus, the sticking of the unnecessary glass can be avoided.

Title: Air cleaning device
Inventor: KAMIYAMA KAZUMI
IPC: F24F7/00
Filed: 1988-02-05
Abstract: PURPOSE:To prevent deterioration of the life of a high-voltage generation part circuit due to heat and thereby increase the safety of a device by providing a timer means which receives a signal from an abnormality detection means and controls a power supply switching means for the high voltage generation part and a frequency measuring means which measures the frequency of abnormal detection signal. CONSTITUTION:High voltage between electrodes decreases by the load characteristics of a transformer, when abnormality occurs due to a reduction in a distance between the electrodes caused by the penetration of foreign matter into a charge part 3. This reduction is detected by an abnormality detection means 4, and a timer means 5a of a control part 5 is actuated by the abnormality detection signal. Consequently, a relay contact (power supply switching means) 6 is set OFF by a set time to stop the action of a high-voltage generation part 2 and thereby equipment is protected against any accident. In addition, after the lapse of a prearranged time, the relay contact 6 is turned ON to determine whether or not any abnormal state continues. If any abnormality continues as a result of the determination, the relay point 6 is turned OFF to detect an abnormality twice in succession. These abnormalities are checked by a frequency measuring means 5b and at the same time, a display means is caused to flash as a warning to a user.

The beam going out of the wedge base 3 enters a second wedge base 10 rotated by a motor 8 through a gear 9 at the different rotating speed from the first wedge base 3, and the optical axis is bent in the same way. The laser beams are then converged by a lens 13 and focused on a piston 16 so as to generate plasma light 17, thus igniting and burning methanol 19 jetted from an injection nozzle 18.

Filed: 1991-02-20
Abstract: PURPOSE:To maintain the whole ability of a compressor device under the condition that the rotating number is constant at the time of lowering of the performance after the intermediate cooling by automatically changing angle of a stationary blade of an axial-flow compressor at the time of lowering of the performance of a high pressure stage of a compressor device to maintain the discharge pressure or discharge capacity of the compressor device constant.

Title: Television receiver with automatic setting function
Inventor: TSUTSUI TOSHIAKI
IPC: H04N5/44
Filed: 1987-02-06
Abstract: PURPOSE:To prevent a program from being missed and to prevent a power source from being forgotten to be switched off by providing a control part equipped with a timer function and a sequence control function, and executing channel reservation and automatic power source cut off by means of the control part. CONSTITUTION:A numerical input key 2 inputs a reserved time, a channel or a time until an automatic power source is turned off. A microcomputer 4 transmits a channel switching instruction for a tuner 7 to set a channel which has been reserved when it comes to a time stored in a memory 3, and said computer turns on the power source. If it is already conducted, the computer transmits only the channel switching instruction. If the automatic power source off function is set, the microcomputer 4 transmits the power source off instruc tion for a power source part 8. Thus, the channel which has been set is received if it comes to a set time, and the power source is turned off when it comes to other set time.
