Title: Process for roughening surface of electrophotographic sensitive body
Inventor: MIYAZAWA MAKOTO
IPC: G03G5/08
Filed: 1987-09-17
Abstract: PURPOSE:To prevent a grindstone from loading and to permit execution of uniform roughening of the surface of an electrophotographic sensitive body by rotating a cylindrical grindstone around a central axis inclined to a face vertical to an axis of rotation of the photosensitive body, and pressing thereby an end face of the grindstone to the photosensitive body. CONSTITUTION:A photosensitive body 1 is rotated around a central axis 11, and plural numbers of cylindrical grindstone 21, 22 are revolved around central axes 41, 42 which makes <=45 deg. angle to a plane vertical to an axis of rotation 11 of the photosensitive body, respectively. Thus, the surface of the photosensitive layer of the photosensitive body 1 is ground by the end surface of the grindstone 21, 23 by sending the grindstones in the axial direction 11 of the photosensitive body 1. A contact area of the grindstone with the photosensitive body is lessened because a rotating cylindrical photosensitive body 1 is allowed to contact with cylindrical grindstone 21, 22, and a contact part of the end surface of the grindstone 6 is altered always in accordance with the rotation of the grindstones 21, 22, Thus, the grindstones are prevented from loading, and fallen abrasive grains are removed smoothly, without fear for generating scratches or partial unevenness on the surface of the photosensitived layer.

Title: Method for reducing amount of sludge
Inventor: UCHIYAMA NAOAKI
IPC: C02F11/06
Filed: 1988-09-20
Abstract: PURPOSE:To markedly reduce the amount of sludge difficult in disposal by effectively decomposing org. substances in sludge by together using treatment with a medium stirring type mill and oxidation treatment with hydrogen peroxide. CONSTITUTION:The solid concn. of org. sludge such as sewage sludge is intensified to about 5-6%. About 30-35% aqueous hydrogen peroxide is supplied to a medium stirring type mill along with the conc. sludge so that hydrogen peroxide in sludge is concentrated at about 3-10% to apply grinding treatment to the sludge.

Title: Production of electronic parts
Inventor: OKABE NORIO
IPC: H01G13/00
Filed: 1988-09-19
Abstract: PURPOSE:To improve tarnish resistance, solderability and bondability and to prevent the occurrence of voids and dewedding at the time of heat melting by forming bright tin or solder plating layer on electronic parts with a plating soln. contg. an org. brightener and by heat-treating the electronic parts at a specified temp. CONSTITUTION:When a printed circuit board, a lead frame for a semiconductor and other electronic parts are produced, prescribed metal substrates are subjected to bright tin or solder plating. Since a plating soln. used contains an org. brightener, org. matter deposits as eutectoid in the resulting bright tin or solder plating films. At the time of soldering or bonding to a semiconductor device, the org. matter vaporizes by thermal decomposition to generate bubbles and these bubbles cause the occurrence of voids and ununiform wetting called dewedding. In order to prevent the occurrence of such defects, the org. matter in the plating layers is deformed and degenerated by heating the electronic parts to a temp. of 80-120 deg.C below the m.p. of the plating metal.

Abstract: PURPOSE:To accurately uniformize the feed speed of a paper on a platen by adjusting and controlling respective rotation driving means based on respective feed speed computed by a platen feed speed computing means and a preset reference feed speed. CONSTITUTION:When the set value (i) of a variable area (i) is 4, a standby state is set until a test paper is fed again. When the test paper is fed again, the times t1-t4 from the time when the test paper is sensed to the time when its rear end is sensed by all of a first paper sensor to a fourth paper sensor are measured respectively. Whether the times t1-t4 thus measured are equal to the reference time (t) corresponding to all the preset reference feed speed (v) or not is judged. When any one or more of the measured times t1-t4 are not equal to the reference lapse of time (t), the process should be back to the step 1 again. When the measured times t1-t4 are all equal to the reference lapse of time (t), the correction is completed and the pulse memory correction process is all complete.
