Title: Method of alkylation
Inventor: YOSHIDA ZENICHI
IPC: B01J27/18
Filed: 1985-02-18
Abstract: PURPOSE:To obtain an alkylcyclopentadiene useful as an additive for synthetic rubber, a resin raw material, industrial chemical, etc., by reacting a cyclopentadiene with an aliphatic lower alcohol in the presence of an alkaline (earth) metallic salt catalyst in a gaseous phase. CONSTITUTION:A cyclopentadiene (e.g., cyclopentadiene, or monomethylcyclo pentadiene) is reacted with an aliphatic lower alcohol (e.g., methanol, or butanol) in the presence of an alkaline (earth) metallic salt catalyst (with the proviso that alkaline earth metal carbonate is omitted) in a gaseous phase, so one alkyl group is introduced into the cyclopentadiene. The reaction temperature is preferably 400-550 deg.C. The catalyst can be highly active in the reaction by calcining it in an inert gas atmosphere at 400-800 deg.C. When a carbide is attached to the catalyst after long-time use, it can be regenerated by calcining it in an air or oxygen-containing atmosphere at 400-800 deg.C.

Title: Cleaning device of copying machine
Inventor: ASAHINA YASUO
IPC: G03G21/00
Filed: 1982-02-26
Abstract: PURPOSE:To prevent effectively a one side contact of a cleaning blade against the surface of a photosensitive body, by forming one of a holder and a bracket for holding the cleaning brade, by the surface of a low friction coefficient. CONSTITUTION:The lower step of a holder 2 is stuck to the base part of a cleaning blade 1, and a resin plate of a low friction coefficient is stuck to an upper face 2a of the upper step. The holder 2 and a bracket 4 are supported by one point through a screw hole 3, a bush 6 and a set-screw 7. The bracket 4 is supported rotatably by a shaft 8, and is energized by a spring 9, but the holder 2 contacts with the bracket 4 by small friction resistance, therefore, the tip of the blade 1 contacts uniformly in its axial direction, against the surface of a photosensitive body 10, and good cleaning which generates no one side contact is executed. Also, even if a removed toner adheres onto the upper face 2a of the holder, it does not adhere as it is since it has a good parting property, and a motion of the blade is not obstructed either.

CONSTITUTION:On a face H of the second optical integrator (hereinafter OP) 11, many secondary light source images which are formed on a face D of an OP4 are all superposed, therefore, a light intensity distribution (h) of the face H becomes flat. Also, on the emitting face of each element lens of the second OP11 positioned in the rear side, a reduced image of the face D of the OP4 is formed, and on a face I, the secondary light source image of the secondary light source is formed. Accordingly, on the face I, its reduced image is formed by the number of element lenses, a light intensity distribution (i) of the face I has a flat characteristic as a whole although there is a fine intensity difference, does not become like a ring-band as a light intensity distribution (d) of the face D, and a light intensity distribution (e) on a reticle R has a flat characteristic since light emitted from each element lens of the second OP11 is all superposed.

Title: Confocal disk
Inventor: ISHIHARA MITSUHIRO
IPC: G02B21/00
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To reduce stray light by increasing lighting efficiency by providing reflecting surfaces, which are coaxial with pinholes on the confocal disk and gradually expand from the pinhole openings in the direction where illumination light is made incident, by the pinholes. SOLUTION: On the confocal disk 1, fine light guide parts 2 are arranged spirally. Each light guide part 2 is structured by cutting the pointed part of a cone so that the diameter of the cross section becomes equal to pinhole size needed for confocal constitution and in a tapered cylinder shape whose top and bottom surfaces are not covered, and the internal surface is a mirror surface. Parallel luminous flux which is parallel to the center axis of the cone is made incident as illumination light. The incident luminous flux is reflected repeatedly by the reflecting internal surface of the cone or not reflected at all to travel toward the pointed part of the cone, so that it is emitted from the tip hole finally at a large divergence angle.  The illumination light never returns from the reflecting surface of the cone when the angle of the slanting surface of the cone is not very large, and the illumination light which entering the cone is all emitted from the hole.

Title: Magnetoresistance element
Inventor: WATANABE TOORU
IPC: G01R33/09
Filed: 1983-02-28
Abstract: PURPOSE:To obtain the subject element of high reliability, offset voltage thereof is adjusted easily and an adjustment thereof is unnecessitated, by arranging a resistor so that the quantity of a bridge offset is not related with temperature distribution in a substrate. CONSTITUTION:Resistors are disposed so that the quantity of offset of a bridge in a magnetoresistance element, which is formed in a plurality of resistance substances having a magnetoresistance effect and in which these resistors are constituted to a bridge shape and used, is not connected with temperature distribution in the substrates. For example, the pitches (a) of hairpin loops M'1-M'8 consisting of linear patterns 3 of ferromagnetic substance films are shaped at the equal pitches of lambda/4, 3lambda/4, 5lambda/4, 7lambda/4, 11lambda/4, and the loops are connected externally as shown in the figure. Accordingly, a magnetoresistance element, offset voltage thereof hardly varies, can be prepared even when temperature distribution is generated in a chip by the generation of heat of the element and the temperature of atmospheric air because the positions of each group are arranged approximately alternately in a group A' consisting of the loops M'1-M'4 and a group B consisting of the loops M'5-M'8.
