Title: Image forming method
Inventor: KAWAMURA TAKAO
IPC: G03G15/05
Filed: 1991-04-24
Abstract: PURPOSE:To provide an image forming method in which corona charging is unnecessitated and sufficient image density and excellent image quality are obtained. CONSTITUTION:Developing bias voltage is impressed on a photosensitive body 2 constituted by successively laminating a light transmissive conductive layer, a carrier injection preventing layer, an amorphous silicon-based photoconductive layer, and a photoconductive amorphous silicon carbide surface layer on a light transmissive supporting body 3 through conductive magnetic toner. Then, the photosensitive body is exposed from the light transmissive supporting body side with the light of specified wavelength which is substantially absorbed by the layer thickness equal to or under that of the photoconductive layer, and optical carrier is temporarily trapped in an area corresponding to a bright part just under a surface insulating layer, then the toner is made to adhere to the surface of the photosensitive body with electric field generated with the optical carrier by interposing the surface layer. While the toner is moved to a transfer part, the charge of the toner and the trapped optical carrier are neutralized through the surface layer and the toner is transferred to a recording paper.

Title: Control of step motor
Inventor: TAKANO AKIHISA
IPC: F24F11/02
Filed: 1979-07-24
Abstract: PURPOSE:To enable control of a rotary angle of a step motor without using a reference position detecting switch by rotating the rotary shaft of the step motor toward a stopper at a predetermined angle to collide a damper with the stopper. CONSTITUTION:When wind blowing angle is regulated by rotating elevationally a shaft 6 connected at a damper 4 to a step motor as a center to cause the damper 4 to collide with a stopper, the damper 4 is stopped rotating. The step motor for driving the damper 4 is controlled by a program stored in a microcomputer 26 to supply a drive signal through a driver 25 to motor windings 16a-16d. The reference position of the damper is set in an internal counter for the microcomputer 26. When the rotating damper 4 collides with the stopper 11 to complete predetermined energization of the predetermined number by the microcomputer 26, the motor becomes one-phase energization to stop the motor 1.

The computer 3 confirms the instructed loading ways of disks and these disk numbers based on the contents of disks. In such a constitution, the function of only a disabled extracting means when detected is stopped and another extracting means is actuated.

Abstract: PURPOSE:To supply cold or hot air quietly and comfortably which is cool at the head level and warm at the foot level by disposing an air outlet for the evaporator in the upper part of the unit main body and an air outlet for the condenser in the lower part of the rear panel, incorporating a heater unit in the condenser air duct, and providing the evaporator and the condenser respectively with a dedicated fan motor. CONSTITUTION:For cool air mode operation in the summer season, the evaporator fan 10 and the condenser fan 11 are operated to cool the air in the evaporator 2, the cool air being blown out of the cool air outlet 17 disposed in the upper part toward the upper parts such as face or chest of occupants staying in the room so they may feel cool. The heat absorbed in the condenser 3 is released to the rear out of a warm air outlet 18 disposed in the lower part so that the warm air may not be blown to the occupants. In the winter season, the unit main body 1 is turned on its caster wheels 16 to direct the warm air outlet 18 disposed in the lower part in the rear panel toward the occupants. Because the evaporator fan motor 19 is stopped, the operation is quiet without noise from the evaporator fan 10.

IPC: G11B5/55
Filed: 1984-05-14
Abstract: PURPOSE:To shorten the access time to operate a magnetic disc device at a high speed by varying a preload quantity to two stages at least in the magnetic disc device having a preloaded rack and pinion mechanism. CONSTITUTION:The magnetic disc device is provided with a carriage 1 for access motion where a magnetic head is mounted, a guide shaft 2 of the carriage 1, and a pinion 3. A rack 4 is engaged with the pinion 3 to convert the rotation to a rectilinear motion, and a preloading mechanism 5 gives two stages of preload to the rack. In the preloading mechanism 5, the preload quantity is determined by balance between springs 15 and 11 when power is not supplied to a solenoid 14, and the preload quantity is reduced to reduce the load of a driving source because the force which compresses the spring 15 and expands the spring 11 is applied when power is supplied to the solenoid 14. Consequently, the access time is shortened to operate the magnetic disc device at a high speed.
