Title: Transfer paper separating device
Inventor: SHIMOZAKA HISANORI
IPC: G03G15/14
Filed: 1993-11-01
Abstract: PURPOSE:To reduce the electric charge transfer amount between a separating roller and a photoreceptor without lowering separation ability of the transfer paper and to prevent the photoreceptor from deteriorating in an early stage by positioning the part of minimum electric resistance value in the radial direction of the separating roller at the least passing zone of the transfer paper to be used. CONSTITUTION:As the roller part 112 of the separating roller 110 is formed so as to be thicker in diameter at the center part and to gradually become thinner in diameter corresponding to the axial direction toward the both end, the thickness of the roller part 114 fitted to the roller shaft 112 is thinner at the central part and gradually becomes thicker corresponding to the axial direction toward the both end. The electric resistance value in the radial direction of the separating roller 110 is smaller at the central part and the electric resistance value is gradually increased corresponding to the axial direction toward the both end. Therefore, on the surface of the roller part 114, the potential becomes smaller corresponding to the direction toward the end part and the movement of the electric charge between the roller part 114 and the photoreceptor 2 is reduced at the end part. Thus, the deterioration speed of the photoreceptor 2, due to the movement of the electric charge when the transfer paper passes through, is reduced and the service life of the photoreceptor 2 can be prolonged.

IPC: H02J1/00
Filed: 1993-10-04
Abstract: PURPOSE:To dispense with a DC-DC converter, reduce a cost, and energy loss by providing a controller which so controls an inverter that the generating voltage of a rotary electric machine and a turbine generator are substantially a battery voltage. CONSTITUTION:A rotary electric machine 11 is arranged on a turbocharger 7 and driven as a generator or a motor. A turbine generator 16 of an inductor is driven by exhaust gas. A first flat circuit 36 is connected to a dc side of a first inverter 19. A second flat circuit 37 is connected to a dc side of a second inverter 33. A circuit switcher 38 is provided for switching the connection between the first and second flat circuits 36, 37 and a battery 29.

Title: Method for heating and cooling metal and device therefor
Inventor: AZAMI MASUTAROU
IPC: C21D9/52
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To restrain the rapid lowering of heat transmission under mutually contacting condition of solids caused by the development of air gap by holding a heating material or a cooling material and a heating source or a cooling source under press-contacting condition or to have the interval of <= a specific size and filling gaseous hydrogen into the gap between both materials. SOLUTION: The interval is set to <=2 mm and the gap between both materials is filled up with the gaseous hydrogen. For example, molten steel 11 is cast into a mold 12 for continuous casting and the outer shell 14 of a cast slab 13 is formed and becomes the solidified shell 15 by rapidly growing with the contact-cooling having large heat transmission at the upper part of the mold 12, but a part of the outer shell 14 is separated from the surface of the mold 12 due to the shrinkage caused by solidification and the thermal deformation caused by cooling in about few sec to develop the air gap 16. As a result, the cooling capacity at this position is quickly and largely lowered causing to unevenness of the solidified shell thickness. Then, at the time of injecting the gaseous hydrogen having large thermal conductivity into the air gap 16 from gas introducing holes 17, the heat insulation of the air gap 16 is broken and the heat transmission is drastically improved.

Title: Protection apparatus for endoscope
Inventor: TANAKA KO
IPC: G02B23/24
Filed: 1993-11-01
Abstract: PURPOSE:To block flare and ghost in an observation optical system by a method wherein a stepped part side of an emission window and an incident window with the external surfaces thereof made to flush and thicknesses thereof mutually different is arranged as a light shielding part to prevent eclipse. CONSTITUTION:Light directing toward an objective lens 19 in the light reflected from an internal surface 33e of a transparent window part 33a is shielded with a light shielding projection 22 provided on the surface of a tip structure part 13. The transmission light directs to an internal surface 33g of a transparent window part 33b facing the objective lens 19 but is shielded with a side light shielding surface 34 involved of a stepped part. As a result, the reflected light on the side of the internal surface 33g of the transparent window part 33b can be shielded effectively, which facilitates the prevention of the generation of flare or ghost caused by the reflected light. As the external surface of a transparent window 33 makes a continuous flat shape, a humor and a mucosa can be removed easily by a jetting of water to block the generation of the flare and ghost caused by reflection. Moreover, this constitution enables the transmission of all illumination light effectively and eliminates possibility of causing a loss in the quantity of the illumination light and eclipse in a visual field thereby obtaining a very good observation image.

Title: Dynamic brake circuit for electric railway car
Inventor: SENZAKI FUMIO
IPC: B60L7/04
Filed: 1985-12-05
Abstract: PURPOSE:To prevent the re-skid of a wheel positively by limiting traking force on the readhesion of the wheel to the adhesion braking force or less of the wheel. CONSTITUTION:When a spotting command is set at speed of 100km/hr on the starting of dynamic braking during idle operation, a cam-shaft normal-rotation relay 2 is operated through a contact 7a for a spotting relay and contacts 8a, 9a, 10b for a speed relay. Consequently, a cam-shaft operating motor 1 turns a cam shaft 12 up to the position of braking corresponding to speed of 10km/hr in the forward direction. Braking currents are restricted to a predetermined value or less by a current-limiting relay contact 11a at that time. When a contact 4a or 5a for a skid detecting relay is closed, a cam-shaft reverse-rotation relay 3 is operated and the cam-shaft operating motor 1 is rotated in the opposite direction, thus lowering braking force.

IPC: G02F1/1337
Filed: 1988-10-29
Abstract: PURPOSE:To prevent the deterioration in display quality even in environment where the display device is subjected to mechanical and electrical stresses by applying a thermoplastic material to spacers, spraying the spacers onto one substrate and heat-treating the spacers, thereby fixing the same. CONSTITUTION:A transparent electrode 4 is formed on one substrate 2 of an LCD 1 and an oriented film 7 consisting of a polyimide film is provided thereon and is subjected to a prescribed orientation treatment. The thermoplastic resin, such as, for example, polyethylene resin, is applied on hard plastic beads 8 which are the spacers and the beads are sprayed on the substrate by using a freon dispersant. The beads 8 are thereafter subjected to the heat treatment for about one hour at 170 deg.C and are fixed to the oriented film 7, following which the LCD 1 is completed. Since the pacers are fixed to one substrate, the undesirable movement of the beads 8 is obviated even when the device is subjected to bending, rolling, etc. The uniform layer thickness is thus maintained.
