Title: Cleaning device of electronic copying machine
Inventor: HASHIZUME SEIZOU
IPC: G03G21/00
Filed: 1977-11-18
Abstract: PURPOSE: To recover the toner securely in a simple constitution, by sealing the toner in uncleaned part with filled seal member while removing the toner by means of magnetic brush, cleaning blade and others.  
     CONSTITUTION: As the copying unit starts to operate, a solenoid 27 is excited, and due to the elastic force of metal piece 17, 18 through links 24, 21 and a lever 20, a cleaning blade 12 is pressed against a photosensitive drum 6 without damaging the drum 6, so that an excess toner on the drum 6 is removed by said blade 12 and a spirally filled magnetic brush 13, thus cleaning. On the other hand, on the uncleaned position on the drum 6 is pressed a seal member 14, which directs towards the tangential direction of the drum 6, having nylon fibers 30 filled in a material such as polyurethane 29. This member 14 not only removes carriers but also seals external falling of toner removed by the brush 13 and blade 12, so that secure recovery and re-use of excess toner may be realized in a simple constitution not requiring, for instance, vacuum suction.

Title: Brushing roll machine
Inventor: HOTANI SETSUO
IPC: B24B29/00
Filed: 1986-06-13
Abstract: PURPOSE:To achieve the demand for the device in reasonable ways by allowing a brushing roller to be transferred between the contact position with an article to be brushed and the position keeping a space from said position, by a motor. CONSTITUTION:A brushing roll 1 is transferred between the first position (brushing operation position) and the second position keeping a space in 50-80mm from the first position, by the operation of a variable electrode quantity motor as motor 3 or an air cylinder plunger 31. The displacement of the brushing roll between the first position and the third position keeping 1-3mm from the first position is carried out by a motor 3. The transfer of the roll 1 between the first and the second positions serves to bring the roll 1 to a prescribed position when the machine is put into stop or the machine starts operation from the stop state. Further, the displacement of the roll 1 between the first and the third positions serves to bring the roll 1 to a prescribed position when the traveling of a material (a) to be brushed is stopped or said traveling is restarted from the stop state.

Title: Insulated-gate type semiconductor device
Inventor: YOSHIDA ISAO
IPC: H01L27/088
Filed: 1988-06-08
Abstract: PURPOSE:To enhance a gate breakdown-strength yield and the reliability of a vertical type MOSFET by a method wherein a composite film of a different dielectric constant such as a composite film of a tantalum oxide film and a silicon oxide film is used as a gate insulating film of the vertical type MOSFET. CONSTITUTION:A gate insulating film is constituted of a composite film composed of a silicon oxide film 5, a tantalum oxide film 6 and a silicon nitride film 7; a low-concentration drain region 2 is formed under the gate insulating film. A p-type base region 3 and an n-type base region 4 are formed; after that, the gate insulating films 5, 6, 7 are formed. Accordingly, it is not required to execute a high-temperature heat-treatment process such as, e.g., a base diffusion process or the like after the gate insulating film has been formed. In addition, when a gate region is formed to be a U-shaped groove, it is difficult to keep the gate insulating film in a uniform thickness; when the insulating film is thin, a pinhole or the like is produced easily; accordingly, it is necessary to make s film thickness large.

Filed: 1982-08-10
Abstract: PURPOSE:To prevent the supply of high-temperature exhaust gas into a housing tank by controlling the opening and closing of a valve provided to an exhaust tube leading to a combustion chamber and an inlet tube. CONSTITUTION:When the pressure-sending and discharging time of powdery granules is elongated, the temperature of water in a water scrubber 10 is raised, and thereby the temperature of exhaust gas coming through the inlet tube 7 to an outlet 4 is raised. In this case, the temperature of the exhaust gas is detected by a detector 24, and when the temperature rises beyond a given one, it is sent out to a control circuit 21. By the control circuit 21, an alarm device 25 is operated or a signal is sent out to solenoids SOLA and SOLB to switch the valves 22 and 23. In short, the valve 22 is opened, the valve 23 is closed, the engine 5 is switched to no-load operation, and at the same time the inlet tube 7 is closed. Consequently, the supply of exhaust gas to the water scrubber 10 is interrupted.
