Patent JP-S5724486-A (JP)
Title: Scroll compressor
Inventor: NAKAMURA TOSHIYUKI
IPC: F04C23/02
Filed: 1980-07-21
Abstract: PURPOSE: To prevent burning of a bearing shaft by providing an excentric hole passing through a driving shaft and by allowing a boss for a scroll member to pass through the excentric hole, supporting and connecting.  
     CONSTITUTION: The length of a boss 5 for an oscillating scroll 2 is extended until the boss passes a crank shaft 6. The boss 5 is supported with a bearing liner 7a pressed into the upper end of the crank shaft 6 and a bearing liner 7b which is pressed into the lower end of the crank shaft 6. With this construction, a radial direction force applied to the oscillating scroll 2 is dispersed, thereby preventing burning of the bearing due to an excentric motion.

Title: Electrophotographic copier
Inventor: SAITOU TSUNEO
IPC: G03G15/00
Filed: 1979-08-08
Abstract: PURPOSE:To correct unevenness of photoreceptor sensitivity and to enable always superior images to be obtained, by rotating a photoreceptor with illuminating it in the range of warming up in a fixing. CONSTITUTION:Turning on a power supply button lights heater lamp 17 and destaticizing lamp 11, rotates the drive motor of photoreceptor 3, and keeps shutter S open. In a warming up state until the atmospheric temperature of fixing unit 16 reaches a given temperature, photoreceptor 3 is illuminated with lamps 17, 11. Since photoreceptor 3 is rotated by turning on the drive motor, it is illuminated with lamps 17, 11 uniformly on the circumference, thus permitting residual potential on the surface of photoreceptor 3 to be uniformly removed and light fatigue to be made uniform, and therefore sensitivity change due to initial characteristics to be minimized.

Title: Oil pressure control valve
Inventor: AIKAWA HIROSHI
IPC: G05D16/10
Filed: 1988-04-22
Abstract: PURPOSE:To steeply change output oil pressure only within a fixed range of signal oil pressure by attaching a plunger which can move relatively to a spool as far as a fixed distance and partially receive signal oil pressure to a signal oil pressure port, and providing a spring to energize the plunger in a direction opposite to the signal oil pressure. CONSTITUTION:In the case where signal oil pressure Ps is below a certain value, the motion of a plunger 4 is checked by a spring force of a spring 5. The signal oil pressure Ps acting on a pressure face of a spool 2 therefore balances with output oil pressure returned to an output oil pressure return port 11, and the ascending slope of the output oil pressure P to the signal oil pressure Ps is gentle. In the case where the signal oil pressure Ps exceeds the certain value, the plunger 4 moves to abut on the spool 2, and the signal oil pressure Ps acts on the sum of the pressure areas of the plunger 4 and of the spool 2, and the ascending slope of the output oil pressure P to the signal oil pressure Ps becomes steeper to increase the output oil pressure.

Title: Faraday element for optical current transformer and optical current transformer using the same element
Inventor: KUROSAWA KIYOSHI
IPC: G01R15/24
Filed: 1993-04-27
Abstract: PURPOSE:To provide the Faraday element for the optical current transformer stable to a temp. change and the optical current transformer by using glass having a specific compsn. and an optical elastic constant within a specific range. CONSTITUTION:This Faraday element consists of the glass having the compsn. consisting, by weight %, 70 to 82% PbO, 16 to 28% SiO2, 0.1 to 2.0% Na2O+K2 O and 0 to 5% B2O3+Al2O3 and having the optical elastic constant within the + or -0.01 (nm/cm)/(kgf/cm<2>) range. The compsn. of the glass medium is so devised as to make the optical elastic effect small. The optical elastic effect is a result obtd. after two factors are synthesized. The lattice effect is generated as the atom position is shifted by a stress, by which the negative optical elasticity is induced. The atom effect is generated by deviation of the atoms from the equil. position by the stress, by which anisotropy is generated in the polarizability of the atom and the positive optical elastic effect is induced. The magnitude of the such effects of the opposite polarities depends on the kinds and contents of the oxides constituting the glass and the glass having the small optical elastic effect is obtd. by adequately selecting these oxides.

Abstract: PURPOSE:To operate a crew protection device more accurately, by judging abnormality of a backup capacitor and an operating unit based on the discharge condition of the backup capacitor when power is interrupted through a switch. CONSTITUTION:When an ignition switch 2 is opened, a backup capacitor 9 is discharged through a discharge path comprising resistors 17, 18 and an ignition circuit 200 thus lowering the recharge voltage gradually. When the voltage Vc at the joint between the resistors 17, 18 drops below a predetermined value V1, a comparator 12 produces a detection signal S1, while when the voltage Vc drops below a predetermined level V2 a comparator 13 produces a detection signal S2. A microcomputor 19 receives the signals S1, S2 and a signal S3 indicating opening/closing of the switch 2. Upon judgement of abnormal circuit, a transistor 20 is turned ON and an indicator lamp 3 is lighted when the switch 2 is closed next time.

Filed: 1981-06-30
Abstract: PURPOSE:To reduce a minor lobe to improve a direrctional pattern, by winding an eddy current generating coil so that the windig density is high in the inside and is low in the outside. CONSTITUTION:When a DC is flowed to a magnetic field generating coil 2 wound around an iron core 1, a magnetic field B is generated near the surface of a material 4 to be examined. A gnerating coil 3a arranged on the lower face of the iron core 1 is wound spirally so that the winding density is high in the inside and is low in the outside. When a current (i) is flowed to the eddy current generating coil 3a, an inside density II of the eddy current is higher than an outside density Iphi, and an inside force FI of a force F generated on the surface of the material to be examined is larger than an outside force Fphi. It is known that a minor lobe is suppressed when the peripheral part is oscillated more weakly than the center in the field of the ultrasonic oscillator, and thus, the minor lobe becomes smaller than conventional lobes.
