Title: Developing device
Inventor: KIN HIDENORI
IPC: G03G15/08
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To prevent the leakage of a developer and to reduce the occurrence of the flocculation and solidification of the developer by sealing only a remote region from a latent image carrier with a seal member, on the side surface of a developing roller arranged by bringing it in opposite contact with a supplying roller for supplying the developer. SOLUTION: Four divided areas 14A-14D are assumed on the side surface of a developing roller 10 divided by a first straight line L1 that links the center point O2 of the rotation of the developing roller 10 and the center point O1 of the rotation of a photoreceptor 80 and a second straight line L2 that orthogonally crosses the first straight line L1 and passes through the center point O2 of the rotation. Then, a seal member is arranged in a position without participating in the divided areas 14A and 14B located on the side of the photoreceptor 80 within the limits of the second straight line L2 in the divided areas 14A-14D. Therefore, the seal member participates only in a part of the divided areas 14C and 14D to seal the developer.  Consequently, the infiltration and back flow of the developer, its aggregate, etc., are safely prevented and the generation of a defect in an image can be prevented as well.

Filed: 1994-12-30
Abstract: PURPOSE: To obtain a magnetic display erasing device which is small in size and is enhanced in the erasing efficiency of a magnetic display by arranging a magnet pair disposed with the same poles opposite to each other in position across a magnetic display medium. CONSTITUTION: This magnetic erasing device executes the erasing of the magnetic display obtd. by acting a vertical magnetic field on the magnetic display medium (magnetic display sheet 4) by acting a horizontal magnetic field (ϕh) thereon and is arranged with of the magnet pair 6A, 6B disposed with the same poles opposite with each other in the positions across the magnetic display medium 4. Since the poles across the front and rear surfaces of the magnetic display medium 4 are the same, the magnetic lines of force emitted from the magnetic pole surfaces facing each other of the magnet pair 6A, 6b repulse against each other between the magnet pair 6A and 6B and eventually the plane magnetic field, i.e., horizontal magnetic field, parallel with the magnetic display medium 4, is formed.  The magnetic display formed by the vertical magnetic field is erased by the horizontal magnetic field formed by the magnet pair 6A, 6B by changing the relative positional relations between the magnets 6A, 6B and the magnetic display medium 4.

IPC: G06T3/40
Filed: 1992-12-18
Abstract: PURPOSE:To obtain a reduced image without generating density change at an arbitrary reduction ratio even from a pseudo halftone image obtained by any kind of method. CONSTITUTION:The amount W of white pixel data and the amount B of black pixel data in one reduction target area read out from image memory 12 are detected by a pixel number detecting means 19.

The correct amount H of white pixel data is compared with the amount B of black pixel data, and the pixel data having larger amount is decided as the reduction pixel data S in the reduction target area. An error value detecting means 24 stores a value in which the amount of all pixels in the area is subtracted from W when the data S are shown as the white pixel data in the error memory, and stores the amount W as the error value E when the data S are shown as the black pixel data.

Abstract: PROBLEM TO BE SOLVED: To prevent the bonding of cut faces of piano wire of semicured panels generated in curing by covering the whole mold with a heat-insulation sheet during the period from the pouring of the slurry into the mold to the end of cutting of the semicured material with a piano wire. SOLUTION: A kneaded raw material slurry is poured into a mold and cured with steam by covering the whole mold with a heat-insulation sheet to keep the surface temperature of the slurry or the semicured material in the mold to 70-80 deg.C. As an alternative, the mold is stored at 70-80 deg.C to cure the semicured material. The raw material slurry is converted to a semicured material after pouring the slurry into the mold by this process and the mutual bonding of semicured panels occuring in the curing can be prevented even by shortening the starting time of the high temperature and pressure steam curing with autoclave to about <5.5 hr. The size and shape of the heat-insulation sheet are adjusted to the shape of the mold and the sheet is made of a material resistant to air-permeation and shielding the heat dissipation.

IPC: G05B23/02
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To suppress the down time when control equipment is unable to operate by performing control by an old control unit which has actual results to at least some extent and shortening the use time of the control equipment which is already in operation by test operation of a new control unit. SOLUTION: In a test operation mode, the input signal of a 1st input/output port is transferred to the output signal of a 2nd input/output port where the old control unit 12 is connected and the old control unit 12 is operated first to make it possible to perform normal operation. Furthermore, in the test operation mode, the input signal of the 1st input/output port is transferred to the new control unit 52 as well. The facilities are therefore not stopped during the normal operation of the old control unit 12 and the new control unit 52 can be placed in test operation, thereby suppressing the down time.
