Title: Image forming device
Inventor: ISHII HIROSHI
IPC: G03G15/04
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device where scattering of carrier in a photoreceptor can be suppressed as much as possible. SOLUTION: In this device, an electric field forming member 10 generating an electric field where the carrier of a reverse polarity as electrified polarity of a surface of the photoreceptor among the carrier generated in the photoreceptor is accelerated in a direction of thickness of a film of the photoreceptor is provided in a position faced to the surface of the photoreceptor drum 1 that is irradiated by image beam by an exposure device 3 of an image forming part. Since the carrier that is the reverse polarity to the surface of the photoreceptor among the carrier generated in the photoreceptor is accelerated in the direction of the film of the photoreceptor, the diffusion of the carrier in a horizontal direction due to repulsive force of Coulomb's force between the generated carrier can be kept down.  Therefore, an electrostatic latent image can be formed in a position of exposure on a surface of the photoreceptor at a resolution that is extremely close to a spot diameter of the radiated beam.

IPC: H02M3/28
Filed: 1984-11-27
Abstract: PURPOSE:To increase the efficiency of a switching regulator by determining an overdrive period and a reverse bias period proportional to a pulse width, and deciding an amplitude proportional to a load current, thereby decreasing a switching loss. CONSTITUTION:A switching regulator has an input circuit 1, an inverter 2, a rectifier 3 and a filter 4, and supplies a desired DC output. This pulse width controller synchronously operates the first third pulse width converters 71-73, compares the output voltage with the reference voltage of a reference voltage generator 6 by an error voltage amplifier 5 to convert to a pulse width. The outputs of the converters 71-73 are combined by a pulse width output composite unit 11, and applied to a gain control amplifier 13. The output current is detected by a detector 12, and the amplifier 13 is controlled to the gain proportional to it. Thus, the drive waveform of the inverter 2 can be controlled in response to the switching width and a load current to minimize the rising and falling times in response to the amplitude of the load current.

Abstract: PROBLEM TO BE SOLVED: To easily adjust an installing position of a shaft coupling, and attain working safety and cost reduction by arranging an adjusting ring device having a length-adjusting function at least in one coupling part of the shaft coupling. SOLUTION: An inner cylinder 42 and an outer cylinder 44 of an adjusting ring mechanism 40 are previously relatively rotated to contract in the lengthwise direction, these are installed between the shaft nut 28 end surface of the pump shaft 18 end part and the coupling part 24a end surface installed on a pump shaft 18, and the coupling part 24a is temporarily attached to a proper member. The outer cylinder 44 is rotated, and the inner cylinder 42 is extended up to the collating position with the coupling part 24a end surface along the pump shaft 18 to adjust the length L1 between the inner cylinder 42 end surface and the outer cylinder 44 end surface. After eliminating looseness by additionally fastening, the inner cylinder 42 and the outer cylinder 44 are fixed by a set screw 58.
