Abstract: PURPOSE:To hold the surface potential of the peripheral surface of a photosensitive drum constant and to obtain a copy image with invariably stable density by varying the quantity of exposure of a pre-exposing device according to the frequency of use of an image carrier. CONSTITUTION:The copying machine controls the rotating speed of the photosensitive drum 2 according to the signal of a counter detected by a pulse detector 30, and a control part controls a voltage converter with a predetermined program to control the voltage applied to a light source 20. Namely, a high voltage is applied to the light source 20 in the beginning of repetitive image formation cycles of the same original D to increase its brightness and the applied voltage is decreased gradually as the image formation cycles advance to the end to decrease the brightness, thereby reducing the quantity of exposure of the photosensitive body 2a. Consequently, the surface potential of the peripheral surface of the photosensitive body is held constant and a copy image having invariably stable density is obtained.

Title: Polishing tool
Inventor: ANDO MANABU
IPC: B24B13/01
Filed: 1987-03-19
Abstract: PURPOSE:To enable highly precision finishing accuracy attainable, by using polymeric gelatinized material for a polishing tool. CONSTITUTION:As for hydrophilic gel, a bridge structure is given to a hydrophilic polymer. And, it is set down to a hydrophilic polymer gel tool 6. Since this polymeric gel tool is uniform within three dimensions in the bridge formation and that it is sparsely distributed, it has uniform abrasive grain holding power wherever it may be, thus it will not locally have the large abrasive grain holding power that is caused for a micro-scratch. And, repeatability of this abrasive holding power is adjusted by concentration of a monomeric aqueous solution before polymerization, and a monomer type is altered whereby the abrasive grain holding power is adjustable so that it can be set down to such a tool that has the abrasive holding power suitable for the characteristic of a workpiece. In addition, since rigidity is not so large as pitch, conformability to an aspherical form is large enough, so that it will do not to reduce the tool size in particular. Therefore, the form of a polishing surface is not restricted and thereby the polishing surface of a continuous-discontinuous free curved surface is polishable accurately.
