Patent JP-S5732456-A (JP)
Title: Copy printing method
Inventor: IDE YOUJI
IPC: G03G13/00
Filed: 1980-08-04
Abstract: PURPOSE:To print many copies stably by using an organic photochromic compound as a photoreceptor and by charging it after light-image irradiation. CONSTITUTION:An organic photochromic polymer or organic photochromic compound is dissolved in a solvent together with a polymer, and the solution is applied over a drum-shaped conductive base 1, such as an Al plate 3, to provide a photosensitive layer 2, thus forming a photoreceptor 3. An exposure unit 4 is used to irradiate the photoreceptor 3 an optical image of ultraviolet rays. When corona discharge is performed by a charging corona charger 5 to charge the photoreceptor 3, its irradiated part is being energized, so its charge is lessened to be held on the surface at an unirradiated part, thereby forming an electrostatic latent image. This electrostatic latent image is developed by a developing unit 6 with toner to obtain a visible image. The visible image is transferred to transfer paper 7 by performing corona discharge of the opposite polarity to the toner from the reverse surface of the transfer paper 7 by using a transfer charger 8, thereby obtaining a clear picture printed body.

Filed: 1992-04-24
Abstract: PURPOSE:To reduce a memory capacity, and to attain a high speed conversion by providing a decoding circuit, enlarging/reducing circuit, and encoding circuit, and attaining a pipe line operation. CONSTITUTION:A decoding circuit 21 which is controlled by the first control means of a DMA controller 25 decodes encoded data. The decoded image data are reduced or enlarged by a main scanning direction enlarging/reducing circuit 22, and a subscanning direction enlarging/reducing circuit 23 which are controlled by the second control means of the DMA controller 25, and encoded by an encoding circuit 24 which is controlled by the third control means of the DMA controller 25. Thus, it is not necessary to provide circuits of plural systems by the pipe line operation which allows the first-third control means to synchronously operate in parallel, so that the memory capacity can be reduced, and the high speed image information conversion can be attained.

Title: Magnetic recording and reproducing device
Inventor: MASUDA EIJI
IPC: G11B5/09
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To simplify a circuit compensating the thermal asperity caused by the contact between an MR head and a recording medium in a magnetic recording/reproducing device using the MR head. SOLUTION: A bias current Ib is made to flow into the MR head 2 to detect the change of electrical resistance accompanying the change of magnetization as the change of voltage. When the thermal asperity is generated in a reproduced output (a) by the contact between the MR head 2 and a magnetic disk 3, a component signal (b) of thermal asperity is extracted by a low-pass filter 8. This signal is applied to a bias current setting resistor 13 through an adder 9, then the compensation is carried out by reducing the bias current Ib when the thermal asperity is generated.

Title: Cleaning device
Inventor: MURAKAMI SUSUMU
IPC: G03G21/10
Filed: 1993-05-07
Abstract: PURPOSE:To excellently clean a photosensitive body without increasing a burden imposed on a cleaning blade even when the mirror surface state of the photosensitive body is changed. CONSTITUTION:The mirror surface degree of the surface of the photosensitive body 1 is detected by a reflection type photosensor 9. When the surface of the photosensitive body is the mirror surface state, a high-density fogged toner image is formed at a non-image part on the surface of the photosensitive body 1 and toner is used as lubricant, so that frictional resistance between the photosensitive body 1 and the cleaning blade 7a is made low. When the surface of the photosensitive body 1 is a rough surface state, the frictional resistance is originally low, so that the frictional resistance is kept as the same degree by making the density of the fogged toner image low.

IPC: F01L9/10
Filed: 1984-05-25
Abstract: PURPOSE:To prevent a suction/exhaust valve from jumping by disposing an oil escape path on the end portion of an operating piston and using resistance produced by oil flowing from the oil escape path to a damper port for buffer action. CONSTITUTION:An oil escape path comprising a taper portion 30 is formed on the lower end portion of a hydraulic piston 8 for driving a suction/exhaust valve of an internal-combustion engine. The taper portion 30 is adapted to decrease an open area of a damper port 18 with the descent of the operating piston 8.

Title: Face output working method
Inventor: MIYATA MITSUTO
IPC: B23Q15/00
Filed: 1988-04-28
Abstract: PURPOSE:To enhance working accuracy by calculating the working path that is at a distance from the working path by a finishing allowance and an offset to carry out rough machining, and then carrying out finish machining by the finish. ing allowance by means of the same tool. CONSTITUTION:First, it is judged whether or not a finishing allowance TC is zero, and when it is zero, the cutting condition is set for finish machining. When it is not zero, the cutting condition is set for rough machining, and the sum of 1/2 of the tool diameter and the finishing allowance TC, or the offset in the case of rough machining is calculated, and then a rough machining path 5 is calculated for outputting. Further, whether or not the finishing is to be carried out by the same tool is judged, and when the finishing is not carried out, working is completed in rough machining; while, when the finishing is carried out, after completion of rough machining, the cutting condition is set for finish machining. And, the half of the tool diameter is calculated, and the finish machining path is calculated for outputting. Thus, since rough machining and finish machining can be separately carried out, the finish machining an be carried out in the optimum condition, enabling the finish surface accuracy to be enhanced.

Abstract: PURPOSE:To decrease crosstalk from an adjacent track or to obtain excellent S/N in the time aixs direction by arranging a diffractive means so that its diffracting directoin is in parallel or vertical to a track formed on a disc. CONSTITUTION:When a prescribes signal is recorded by frequency modulation, the diffracting direction by a diffracting grating 11 is made nearly in parallel with the direction of a track 12 in a disc 4. Thus, the spread of the beam of the semiconductor laser of the multi-mode is in the direction in parallel with the track 12 so as to prevent the crosstalk from the adjacent track from being increased. When a prescribed signal is subject to a digital modulation such as EFM modulation in the disc 4, the diffracting direction by the diffracting grating 11 is made nearly vertical in the direction of the track 12. Thus, the beam of the semiconductor laser of the multi-mode is spread in a direction vertical of the track 12 and not spread in the direction of the time axis of the same track, then the deterioration of the S/N in the time axis direction is prevented.
