Patent JP-S6036796-A (JP)
Title: Rotary blade pump
Inventor: UAANAA POSU
IPC: F04C2/344
Filed: 1984-07-11
Abstract: A rotary vaned pump has solid vanes of fixed length sliding in a boss mounted for rotation about a longitudinal axis eccentrically displaced from the longitudinal axis of the pump chamber, so as to provide respective pump compartments in the pump chamber which vary cyclically in volume and are arranged to pressurize fluid entering the pump chamber through an inlet opening and discharging from the chamber through an outlet opening. Each leading vane edge that passes over the inlet opening is formed as a shearing knife edge that shear-cuts any cuttable solid material in the entering fluid that is engaged by the edge as it enters the pump chamber through the inlet. Such solid material is thereby cut into pieces which can be handled by the pump without jamming rotation of the rotor. The leading edge of the inlet opening is also formed as a knife edge that cooperates with the vane edge to shear the solid material. The vanes slide radially in the rotor boss and their tips engage the rotor chamber cylindrical interior surface surrounding the longitudinal axis, this surface being formed as a specially calculated face cam permitting the use of the solid constant length vanes.

Title: One side mirror surface polishing of semiconductor wafer
Inventor: MATSUSHITA HIROYUKI
IPC: B24B37/10
Filed: 1985-07-01
Abstract: PURPOSE:To facilitate mirror surface polishing of the upper surface only of a semiconductor wafer by a method wherein an upper surface plate is turned to the same direction as the direction of revolution of a carrier and a lower surface plate is turned to the opposite direction to make the difference between respective relative speeds large. CONSTITUTION:Both a sun gear 22 and an internal gear 23 turn clockwise. If the rotation speed Ns of the gear 22 the rotation speed Ni of the gear 23, a carrier 21 makes rotation clockwise and makes revolution clockwise with the speed corresponding to the difference between Ns and Ni. Under this condition, an upper surface plate 24 is turned coutner-clockwise with the rotation speed NA and lower surface plate 25 is turned clockwise with the rotation speed NB. If the revolution speed of the carrier 21 is NC, the polishing speed is approximately proportional to (NA+NC) on the upper surface of a semiconductor wafer 11 and approximately proportional to (NBC-NC) on the lower surface of the semiconductor wafer 11. Therefore, by selecting NA, NB and NC properly, the upper surface of the wafer 11 can be finished into a mirror surface where no deteriorated layer produced by processing remains.

Title: Cold cathode fluorescent lamp
Inventor: TAKAHASHI KAZUO
IPC: H01J61/72
Filed: 1990-05-31
Abstract: PURPOSE:To provide a uniform brightness by coating a cylindrical anode with a fluores cent substance over its inner surface, locating a wire-shaped cathode inside the cylindri cal anode, and thereby utilizing ultraviolet rays emitted from neg. glow discharge for energization of the fluorescent substance. CONSTITUTION:Electric discharge is generated by impressing a voltage between an anode 2 and a cathode 4. Because a fluorescent substance film 3 on the anode 2 is charged electrically by this electric discharging, a discharge pause period is provided for canceling it, and voltage is impressed intermittently. When cancel of electric charges on the fluorescent substance film 3 is to be made actively, reverse direction voltage is impressed during the missing periods of this intermittent impression of the voltage. If sufficient discharge current is allowed to flow, neg. glow spreads over the surface of the cathode 4 and its surrounding, and ultraviolet ray emission from the neg. glow is made uniformly form the whole discharge bulb. Thus the fluorescent substance is energized effectively, and efficient light emission is made. Even in a small-sized cold cathode fluorescent lamp. therefore, a vigorous ultraviolet ray emission from the neg. glow, which takes place in the neighborhood of the cathode located on the center axis of a cylindrical anode, can be obtained uniformly form the whole discharge tube, to allow achieving a small-sized cold cathode fluorescent lamp equipped with high brightness.
