Title: Image forming method by photoconductive toner
Inventor: FUSHIDA AKIRA
IPC: G03G15/05
Filed: 1983-01-31
Abstract: PURPOSE:To apply toner to uniform thickness by establishing an alternating electric field between a conductive substrate which has a constant-polarity potential and a coating mechanism which holds toner charged electrostatically to the opposite polarity, and oscillating the toner. CONSTITUTION:The conductive substrate 2 on the surface of a driving drum 1 and the photoconductive toner 6 in the coating mechanism 4 are charged to the opposite polarities, and the toner flows out of a screen 5 through its pores. A DC power source 3 and an AC power source 8 are connected in series between the conductive substrate 2 and screen 5, and a constant DC voltage V1 and an AC voltage V2 are added together, so toner particles between the conductive substrate 2 and screen 5 is oscillated corresponding to the alternating electric field to move the substrate side and screen side alternately. Therefore, all oscillated toner particles are applied to uniform thickness without sticking the substrate 2 owing to factors other than Coulomb force, and the DC voltage is adjusted to control the coating thickness.

Title: Hydraulic pressure generating device
Inventor: WACHI YUJI
IPC: B60T13/12
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To set stroke of an input means to extremely short stroke and surely perform an output by the input means by a simple structure also when hydraulic pressure falls. SOLUTION: In this device, when a rotor valve 8 is rotated by the stepping of a brake pedal 2, a rotary valve 5 generates power hydraulic pressure according to stepping force of the pedal 2. This power hydraulic pressure is introduced into a power hydraulic pressure chamber 20 of an actuator 6, a first piston 22 of a master cylinder 4 generates hydraulic pressure by power hydraulic pressure of this power hydraulic pressure chamber 20 and a second piston 23 generates hydraulic pressure by this hydraulic pressure. Because a rotation amount of the rotor valve 8 in operation in a little amount and pedal stroke is suppressed by power hydraulic pressure acting on an actuator piston 19, pedal stroke becomes ultrashort stroke. Because the first piston 22 is directly operated via the actuator piston 19 by the stepping of the brake pedal 2 when a pump 15 is out of order, the master cylinder 4 is capable of generating hydraulic pressure also when the pump 15 is out of order.

Title: Fixing structure for dielectic resonator
Inventor: INOUE JUN
IPC: H01P7/10
Filed: 1990-01-22
Abstract: PURPOSE:To reduce the cost and to simplify the production process by arranging a dielectric resonator so that its plane parts do not face the surface of a microwave circuit board and the axial line passing these plane parts facing each other intersects a micro strip line and directly attaching the dielectric resonator to the micro wave circuit board. CONSTITUTION:A magnetic field is generated in the direction of the axial line passing plane parts 1a and 1b of a dielectric resonator 1. A magnetic flux F forming this magnetic field crosses a micro strip line 3. Since planes 1a and 1b do not face the surface of a micro wave circuit board 2 in this case, the Q value of a resonance circuit is not very much reduced though the dielectric resonator 1 approaches the microwave circuit substrate 2. Since the dielectric resonator 1 is semicylindrical and its flat part 1d where an electrode film 1e is formed is directed upward, the magnetic flux is scarcely formed above the flat part 1d, and the Q value is not very much reduced though a metallic case covering the microwave circuit substrate is close to the dielectric resonator 1.

Title: Mold for molding of optical reflector and molding method
Inventor: SUGA TETSUO
IPC: B29C45/00
Filed: 1990-01-23
Abstract: PURPOSE:To transfer highly accurately by neither applying unreasonable force to an optical surface nor generating a sink in the same, by a method wherein a core molding an optical reflective surface of a molded product is formed of a magnetic substance, a core molding a nonoptical reflective surface of a molded product is formed of a nonmagnetic substance, and the core of the magnetic substance is magnetized with a magnetic field generating device. CONSTITUTION:A stationary core 7 formed of a nonmagnetic substance and a hollow sleeve 8 formed of a nonmagnetic substance are laid respectively into a retainer plate 4 and movable retainer plate 5. A movable core 9 formed of a magnetic substance is fitted into the hollow part and fixed and the side 9a is mirror-finished for optical reflective surface and a coil 19 is wound round the opposite side. When a magnetic field is generated on a movable core 9 by applying a current to the coil 10 after completion of filling of molten resin 15 mixed with the magnetic substance 14 into a cavity 11, the molten resin 15 is stuck uniformly to the movable core 9 with attractive force. After cooling of the resin, a molded product is taken out after elimination of the magnetic field by turning off the current. Therefore, transfer is performed highly accurately by neither applying unreasonable force to the molded product nor deforming an optical surface since shrinking force during cooling is absorbed by a deformation of nonoptical surface.
