IPC: G03G15/05
Filed: 1980-04-11
Abstract: PURPOSE: To accomplish charging uniformly and easily without depending on corona charging by contactually charging a photoreceptor having an insulation layer on the surface, exposing this and forming electrostatic latent images.  
     CONSTITUTION: A photoreceptor 1 has an insulation layer 4 on its surface, and a charger 5 provided for the purpose of charging is in contact therewith. Also, a charger 18 is in contact after the exposure by a focusing type optical transmission body 16. The surface of the charger 5 and destaticizer 18 are covered with soft contact body 12 made of fur of nylon or the like, so that the pholoreceptor 1 is contactually charged without being damaged. Since these soft contactors 12 of nylon or the like have electric resistance, the charging is uniformly accomplished.

Title: Dressing device of polishing pad for semiconductor wafer
Inventor: DOI TOSHIRO
IPC: B24B53/017
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To improve removal of polishing chips stored and accumulated in a polishing pad by setting a particle size of atomized cleaning liquid to a specific μm range, and colliding it with the polishing pad at a specific speed. SOLUTION: A distance between a nozzle 14 and a polishing pad 50 is set to about 200mm, and water is supplied to the nozzle 14 as a cleaning liquid at a pressure of about 25MPa. The cleaning liquid is atomized to have a particle size of 1μm to 3μm, and is collided with the polishing pad 50 at speed of 10m/s to 500m/s. The particle size is adjusted according to a construction material of the polishing pad 50. For example, when the construction material is porous polyurethane, it is set to 1μm to 300μm, preferably, 1μm to 100μm. Therefore, force to flow polishing chips is optimally secured, and the polishing chips can be rid out. When the flow speed is too small, sufficient kinetic energy is not obtained, and when it too large, there is a danger of damaging the polishing pad 50. The polishing chips can be reliably removed by this constitution.

Title: Bathtub water purifying device
Inventor: KANAZAWA KOTETSU
IPC: F24H9/00
Filed: 1989-02-28
Abstract: PURPOSE:To prevent initial backwash water from getting into the bathtub side by delaying the start of driving a backwash pump by the time required for the opening and closing operation of a valve after an ON-OFF switch of the valve is ON when the bathtub water purifying operation is switched over to the backwash operation of a purifier. CONSTITUTION:When a purifying operation switch 71 is ON, solenoid valves V1 and V2 are opened and water in a bathtub 10 is circulated as shown by a solid line arrow mark by a circulating pump P1 and purification is carried out by a hair collector 20 and a filter 30. When a backwash operation switch 72 is ON during said purifying operation, the circulating pump P1 is OFF and solenoid valves V1 and V2 are closed after time t1 required for closing operation is passed. At the same time, solenoid valves V3, V4 and V5 are opened after time t1 is passed similarly. A delay relay or the like, for example, is used in a manner to constitute the start of driving a backwash pump P2 delayed by the time t1. The backwash water using pure water is discharged, for example, like shown by a broken line arrow mark, passing through discharge lines 4 and 5 to prevent the backwash water from getting into the bathtub 10.

Abstract: PURPOSE:To form a thin-film without frequently exchanging an optical incident window while improving reproducibility by ejecting a gas inactive to incident light on the optical incident window. CONSTITUTION:Pressure in a reaction chamber 1 is held at fixed pressure by a pressure regulating valve 9. The inside of the reaction chamber 1 is irradiated with ultraviolet rays through an inert-gas introducing synthetic quartz window 10 from an ultraviolet lamp 6. Consequently, a material gas in the reaction chamber 1 is excited, and a substance decomposed onto a heated substrate 5 is shaped as a thin-film. Since an inert gas such as Ar, He, H, etc., is blown out of inert-gas exhaust nozzles 11 for the inert-gas introducing synthetic quartz window 10, through which ultraviolet rays are transmitted, when the thin-film formed, there is no decomposition product near the inert-gas introducing synthetic quartz window 10 when the quantity of blowout is adjusted optimally, thus preventing adhesion onto the inert-gas introducing synthetic quartz window 10 of decomposition products.

Abstract: PURPOSE:To prevent the stumbling of a mix door by a method wherein the opening of the mix door is corrected by the output of a temperature sensor installed in the downstream of a blower when a compressor is not operated; and by the output of a fixed resistor for adjusting the mix door when the compressor is operated. CONSTITUTION:When a compressor on-mode switch 40 is turned on, change-over contact points 451 and 453 are connected together and used to operate a temperature sensor 49 to detect the temperatures of a blower and an evaporator. The results detected are input to an input signal operator 47 so that the opening of a mix door 10 is corrected. When a thermostat 44 is turned on while the compressor on-mode switch 40 is being actuated, a relay 46 and the control portion 43 of the compressor operate. The compressor is thus operated through a contact point 431 that has been turned on, so that a fixed resistor 48 is connected to the input signal operator 47. As a result, the opening of the air mix door is corrected by the fixed resistor 48. With this construction, it prevent the stumbling of the mix door and the sudden change of the jetting temperature.

Abstract: PURPOSE:To decrease stray light production without forming a front curtain pattern into a strip shape by providing photodetecting and amplifying means which detect the reflected light from the front curtain provided with a high reflectance part in the center and making the light current under traveling of the front curtain equal to the stored value just before the traveling. CONSTITUTION:The light current of an SPD10 is amplified by the 1st, 2nd logarithmic amplifying circuits 1, 6, and integrated current is supplied to an integrating circuit 7. The switch 18 of the 1st sample holding circuit 2 is opened just before traveling of the front curtain, and the quantity of the light received in the central part of the front curtain is stored in a capacitor 22. During traveling of the front curtain, the difference between the quantity of the received light of that time and the stored value is detected by a subtractor 3 and the detected value is fed back to a constant current circuit 5, whereby the output current thereof is controlled and the integrated current is maintained constant. Just before the end of the traveling of the front curtain, a sample holding circuit 4 is made into the holding state as a switch 34 is opened, so that the output current of the constant current circuit is made constant. Thereafter, direct photometry takes place.
