Title: Production of conductive sheet
Inventor: TAMURA SHIYOUHEI
IPC: H01B1/20
Filed: 1982-12-07
Abstract: PURPOSE:To facilitate the production of a conductive sheet having high resistance locally, by subjecting a fluorocarbon resin conductive sheet to a local alkali metal treatment, and then subjecting the sheet to an acid or oxidation treatment. CONSTITUTION:A fluorocarbon resin conductive sheet is prepared, for example, by a method comprising mixing polytetrafluoroethylene resin powder with a conductive powder (e.g., graphite), a molding aid, etc., and forming the mixture into a sheet. The obtained sheet is treated partially with an ammonical solution containing an alkali metal to effect partial defluorination and to produce saturated or unsaturated hydrocarbon skeletons, carbonyl groups, and carbonyl groups. A conductive sheet having high resistance partially is obtained by immersing the sheet in an oxidation treatment solution such as sulfuric acid solution containing potassium permanganate and sodium nitrate to oxidize the areas subjected to the alkali metal treatment and heighten resistance values of the areas.

Title: Molding flask for molding spacer made of fiber-reinforced cement
Inventor: NANAMA KIYOTAKA
IPC: B28B7/34
Filed: 1987-08-28
Abstract: PURPOSE:To improve the mold parting property of a molding flask and reduce the manufacturing cost as well as the charge for the packing of the same, by forming the molding flask by the heat molding of a thermoplastic resin sheet, having a specified thickness and smooth surfaces. CONSTITUTION:A molding flask 1 is manufactured by forming recesses 2 (and projections 4) on a thermoplastic resin sheet through heat forming. The thickness of the sheet should be less than 5mm and preferably less than 5mm and more than 0.5mm, heat forming becomes difficult when the thickness exceeds 5mm. When the thickness is less than 0.5mm, the molding flask is readily deformed upon carrying it, while incorporating spacers therein and the handling thereof becomes difficult. When the thermoplastic resin sheet is a foamed sheet, the magnification of foaming is preferably less than 50 times and especially less than 30 times. When the magnification exceeds 50 times, the strength of the sheet is reduced and the handling thereof becomes difficult since the sheet becomes too soft. When the foamed sheet is employed, it is preferable to have a skin layer on the surface thereof since the sheet is prominent in the smoothness of the surface.

Title: Cleaner
Inventor: ONO MOTOKO
IPC: H01L21/304
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To provide a silicon wafer cleaner capable of preventing metal contamination. SOLUTION: A contamination metal remover 20 receiving an adsorbent 22 composed of silicon is provided across a circulation passage 13 of an alkali detergent 4. When the alkali detergent 4 which cleaned a silicon wafer 1 comes into contact with silicon composed of the adsorbent 22 of the contamination metal remover 20, silicon is oxidized to form an oxide film. At this time, aluminum or iron which is a contamination metal 5 for the alkali detergent with large oxide film entropy is captured by a silicon oxide film and adsorbed. As the adsorbed contamination metal 5 is not released to the detergent 4, the contamination metal 5 is removed from the detergent 4. Accordingly, as accumulation of contamination metal in the alkali detergent can be prevented, metal contamination of silicon wafers when cleaned can be prevented. The adsorbent can be regenerated by etching the oxide film.

Title: Rotary anode type x-ray tube apparatus
Inventor: OOSUGI YASUSHI
IPC: H01J35/10
Filed: 1985-09-28
Abstract: PURPOSE:To greatly increase the rotation torque of the rotor of a rotary anode without deteriorating the electric insulation between the rotary anode and an induction motor by installing the induction motor between the inner and the outer cylindrical rotors of a rotor with a double cylindrical structure. CONSTITUTION:A target 12 is integrated with a rotor 11 which rotates by receiving the induction field of an induction motor 15. The rotor 11 consists of an inner and an outer cylindrical rotor 11b and 11a. Since the induction motor 15 is located between the rotors 11a and 11b, the rotor 11 completely receives the inner and the outer induction fields of the induction motor 15 and therefore great rotation torque is applied to the rotor 11. Due to a ferromagnetic cylinder 21 and a shaft box 14 which together with the rotor 11 constitute a magnetic path, the permeability of the magnetic path is increased and greater rotation torque is applied to the rotor 11.

IPC: G03G21/10
Filed: 1986-09-16
Abstract: PURPOSE:To prevent the occurrence of color deviation by abutting a cleaning blade to a transfer belt after each color is reciplocatingly transferred and isorating said blade from the belt at the time of transfer. CONSTITUTION:The cleaning blade 40 is fitted to a turnable shaft 41 on the side of discharging a transfer sheet, and normally energized in the direction in which a spring 45 isorates it from the transfer belt 45. A solenoid 44 is linked to the arm lever 43 of the shaft 41. In order to copy plural colors, the transfer belt 1 is rotated normally and reversely three times. After the reciplocating transfer, the solenoid 44 is excited to attract the arm lever 43, and the blade 40 is abutted on the belt 1. Since the belt 1 receives no load from the blade 40 during the transfer, no slip occurs, and the color deviation due to slip can be prevented accordingly.

Title: Voltage regulator for permanent magnet generator
Inventor: ENDO KENJI
IPC: H02K21/12
Filed: 1990-08-16
Abstract: PURPOSE:To stabilize the voltage induced in each phase armature winding of a permanent magnet generator by inserting a magnetic sheet between a pole and a bind covering the outer circumferential face thereof over the outer face of the pole and regulating the flux of each pole to interlink uniformly with each phase armature winding. CONSTITUTION:A transformer electromotive force is induced in an armature winding by the flux of pole where a different voltage is induced for each of the rightmost pole 2, the central pole 6 and the leftmost pole 7 because the flux is disturbed by the dispersion of magnetic circuit due to complex structure of split pole as well as the dispersion of the permanent magnet material itself. A magnetic sheet 12 is inserted between a bind 11 covering the outer circumferential face of the pole and the split pole, i.e. the rightmost pole 2, while spreading to the outer face thereof. Consequently, the rightmost pole 2 inserted with the magnetic sheet 12 increases flux to be interlinked with the armature winding opposing thereto.
