Title: Polyamic acid and production of imide polymer
Inventor: YASUDA YOSHITOMO
IPC: G02F1/1337
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To produce an imide polymer which can form a liquid crystal alignment film having excellent aligning characteristics and which can give liquid crystal displays shortened in the time taken for residual image extinction by reacting a specified tetracarboxylic dianhydride with a specified diamine compound. SOLUTION: 1,3-Divinylbenzene and/or 1,4-divinylbenzene and maleic anhydride are subjected to the Diels-Alder reaction at 80-150 deg.C to obtain a tetracarboxylic dianhydride. A tetracarboxylic dianhydride containing 0.1-100mol% obtained dianhydride is reacted with a diamine compound represented by the formula: H2 N-R<1> -NH2 (wherein R<1> is a divalent organic group) in such a ratio that 0.2-2.0 equivalents of the acid anhydride groups of the tetracarboxylic dianhydride are present per equivalent of the amino groups of the diamine compound at 0-150 deg.C in an organic solvent to obtain a polyamic acid. This acid is cyclized through dehydration at 0-180 deg.C in the presence of a dehydrating agent and a dehydrative cyclization catalyst in an organic solvent to obtain an imide polymer.

Title: Developing device
Inventor: YAMASHITA HIROSHI
IPC: G03G15/08
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a high quality image by forming a thin toner layer stable for a long period of time, and prevent contamination of the inside of a developing device resulting from sputter of a toner. SOLUTION: The thickness of a toner 14 attached to the surface of a developing roller 22 is restricted by a resilient member 30. The toner 14 stagnating or sputtered around the resilient member 30 because of insufficient charging is adsorbed to the surface of the developing roller 22 due to a potential gradient generated between a conductive member 32 and the roller 22. That is, the absolute of a bias voltage impressed on the conductive member 32 is set greater than the absolute of the developing bias voltage to be impressed on the roller 22 so that s potential gradient is generated which causes the toner 14 to transfer to the developing roller 22. Therefor the toner 14 stagnating or sputtered is drawn toward the surface of the roller 22, and a stable thin layer of toner is established.

Filed: 1991-03-06
Abstract: PURPOSE:To perform good connection in order to obtain a highly reliable semiconductor device by performing surface treatment having good mounting ability such as soldering on the part to be mounted with an outer lead while performing surface treatment having poor mounting ability on the part excepting the mounting part of the outer lead. CONSTITUTION:A surface treatment part 1 subjected to surface treatment (for instance, eutectic crystal solder plating of tin : lead=7:3) having a good mounting characteristic is formed in the range to be actually mounted with a lead frame raw material 3 of a surface mounting package. Further, in the range to be not actually mounted, a surface treatment, part 2, where surface treatment having no special consideration of a mounting characteristic, for instance, such as surface treatment not less than tin 90% or nickel plating is performed, is formed. Thereby, siphoning of solder at the time of mounting such as an IR reflow or VPS is stopped thus to prevent generation of a bridge phenomen can be prevented and to exclude scraps of surface treatment generated at the time of molding an outer lead.

Filed: 1984-03-01
Abstract: PURPOSE:To ensure stable tracking draw-in control within a fan-shaped area by setting the different depth of a circumferential track from the track of another area within the prescribed fan-shaped area. CONSTITUTION:The depth of a circumferential guide track of an optical disk 1 is set at lambda/8 in a fan-shaped area OAB and at lambda/5 in other areas. A still jumping action is carried out between points D and E of the area OAB. A jumping drive signal is applied to an actuator at the point D, and a brake signal is applied to a middle point G and reaches a point E. Thus a tracking action is performed. In this case, the track depth is set at lambda/8 within the area OAB and at the different value in other areas. Thus a tracking error signal is delivered at a high level to ensure the stable tracking draw-in control.

Abstract: PURPOSE:To prevent the generation of cracks in an insulating film, and to improve moisture resistance by forming an air gap between a metallic film for a barrier in the periphery of an opening section and an insulating film for a cover. CONSTITUTION:In a semiconductor device with a metallic film 7 for a wiring, an insulating film 8 for a cover formed onto the metallic film 7 for the wiring, a metallic film 11 for a barrier shaped so as to be brought into contact with the metallic film 7 for the wiring through an opening section 10 for an insulating film, and a barrier metallic film formed onto the metallic film 11 for the barrier, an air gap 14 is shaped between the metallic film 11 for the barrier and the insulating film 8 for the cover in the periphery of the opening section 10.
