Title: Creasing cutter blade for plastic sheet
Inventor: HASHIMOTO TADASHI
IPC: B29C53/06
Filed: 1990-11-17
Abstract: PURPOSE:To prevent plastic sheet from bending and the width of a creasing line from widening by a method wherein a cutting edge consists of a plurality of parallel projecting strips and tire angle made between an outside face connecting with an outside cutting tip and the center line of the cutting edge is set to be 15 deg. or less and, at the same time, a recess is made between both the outside cutting tips. CONSTITUTION:By setting the angle (alpha), which is made between the outside face 4 connecting with an outside cutting tip 3 and the center line C of a cutting edge 1 consisting of a plurality of parallel projecting strips 2, to be smaller than 15 deg.C, at the time of intrusion of the cutting edge into plastic sheet 6 under pressing, the horizontal. widening action of the plastic sheet at both the sides of a creasing line 61 by the cutting edge becomes smaller. The cutting edge having the outside face 4, which is over perpendicular or divergent downwards, may be allowable and, in this case, the angle alpha2 made between the outside face and the center line C is preferably set to be smaller than 15 deg.. Further, the cutting edge having the outside face 4, which is parallel to tire center line C, may also be allowable. Furthermore, since a recess 5 is made between both outside cutting tips 3 and the plastic sheet, which is overflooded by the pressing of the cutting edge, flows in the recess 5, resulting in allowing to smoothly produce the creasing line 61 without widening the width of the creasing line 61.

Title: Production of stabilized sodium percarbonate
Inventor: ITO YOSHIRO
IPC: C01B15/10
Filed: 1987-12-11
Abstract: PURPOSE:To obtain sodium percarbonate granules capable of exhibiting high- degree stability even in an atmosphere at a high temperature and humidity, by adding respective specific stabilizers to reaction and granulation in reacting Na2CO3 with H2O2, producing and granulating sodium percarbonate. CONSTITUTION:Sodium carbonate is reacted with hydrogen peroxide in an aqueous medium in the coexistence of an aminopolycarboxylate (e.g., pen tasodium diethylenetriaminepentaacetate or tetrasodium ethylenediamin etetraacetate) to produce sodium percarbonate, which is then separated from the aqueous medium. A polymer (e.g., sodium poly-alpha-hydroxyacrylate) derived from alpha-hydroxyacrylic acid or silicate (e.g., powdery sodium silicate No.1) or both are added, kneaded and granulated to afford the aimed stabilized sodium percarbonate.

Title: Production of capacitor
Inventor: YOSHIIE MASANOBU
IPC: H01L27/04
Filed: 1987-12-11
Abstract: PURPOSE:To minimize leakage current while increasing a capacity value, by heat-treating a metallic layer formed by depositing at least one of TA, Ti, Hf, Zr and Nb, within oxidizable atmosphere while applying ultraviolet rays thereto for oxidizing the same and forming a dielectric layer. CONSTITUTION:A Ta layer 2 is formed on a surface of a silicon substrate 1 serving as a lower electrode by means of the sputtering or CVD process. While irradiated with ultraviolet rays, the Ta layer 2 is thermally treated at 200-300 deg.C within oxidizable atmosphere of oxygen or the like so that the Ta layer 2 is oxidized and formed with a TaO5 layer 21. When oxygen is irradiated with ultraviolet rays, oxygen gas is decomposed to produce oxygen radicals, which help the oxidation of Ta. Thus, the oxidation of Ta can be carried out at a temperature lower than an ordinary thermal oxidation temperature of 400-600 deg.C as required by prior arts, by 100-200 deg.C. Thereby, ununiform reaction as would be caused between the Ta and the silicon substrate is minimized and the Ta2O5 film can be produced without defects such as pin holes or the like and with a thickness by which the Ta2O5 film has good electrical insulating properties.

Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To contrive a color projector having high luminance and of a low cost while utilizing existing light bulbs and also to enable the color projector to perform sufficient gradation expression. SOLUTION: Light from an incandescent light source 1 is split into luminous fluxes of red, green and blue by means of a dichroic mirror 4, these split luminous fluxes are made incident on a lenticular lens 5. This lens works such that it converts the luminous flux of each color entering a rough-pitch lenticular lens to a color band set consisting of sub-bands split into luminous fluxes of 1/3 or less diameter, and emits it from a fine pitch lenticular lens. This outgoing color band set is image-formed on a DMD panel 8 through a galvano-mirror 6a and a coupling lens 7. Then, the color band set is scanned vertically in a reciprocating manner by that pitch on the DMD panel through the turning of the galvano-mirror, while the DMD panel is simultaneously driven, the modulated light is projected from the DMD panel onto a screen by means of a projection lens 9.

Title: Breaker wherein generation of metal particle is prevented
Inventor: OONO MASATOMO
IPC: H01H33/91
Filed: 1988-12-14
Abstract: PURPOSE:To shorten the insulation distance between a grounded container and an electrode so as to make the breaker smaller, by providing a fixed contact and a movable contact, both of which are silverplated, in the contact portion of an electricity transmitting portion, and providing a clearance between arc-resistant metal and the silverplated portion. CONSTITUTION:An electricity transmitting portion is formed from a copper alloy and is soldered at its end with an arc-resistant metal 14, and the contact portion 3 of the electricity transmitting portion is silverplated 15 adjacent the arc-resisting metal 14. If some acids produced by the silverplating remain, adhesion of the silverplating 15 becomes worse, but the silverplated 15 portion can be prevented from flaking when impact is caused by the collision between contacts during switching of the breaker, by providing a clearance 16 between the arc-resisting metal 14 and the silverplated 15 portion to the extent that transmission of electricity between opposite contacts 3 may not be affected thereby. It is thus enabled to prevent narrow and long metal particles from being produced, and the diameter of a gas tank is reduced to enable a gas-blast circuit-breaker to be made smaller and less heavy.
