Title: Sputtering target
Inventor: TAKAHASHI KOUICHI
IPC: C23C14/34
Filed: 1978-04-20
Abstract: PURPOSE:To enable the resistance value, e.g. of a resistance thin film formed to be made constant independently of the no. of uses of a target and a position in a sputtering face by applying one of the exposed faces of a laminate, as a sputtering face, formed by superposing two or more kinds of different sheets. CONSTITUTION:Sheets 1 of resistance material such as Ta and sheets 2 of insulating material such as SiO2 are alternately superposed to a height B. Sheets 1,2 are equal in length a and width H, and different in thickness D1, D2. The resistance value is set according to the ratio of areas which are occupied by sheets 1, 2 in sputtering face 3, respectively, that is, the ratio of the total area of the resistance materials sheets=AXD1Xthe no. of the sheets and the total area of the insulating material sheets=AXD2Xthe no. of the sheets. In order to change this ratio to obtain a desired resistance value, the thickness D1, D2 of the no. of the sheets is varied. When reduction ratio is different after repeated uses, this laminate can be disjointed to exchange consumed sheets, and hence the properties of the resulting  thin film can be made uniform.

Title: Vibration diaphragm
Inventor: TSUCHIYA KAZUO
IPC: H04R7/02
Filed: 1981-03-31
Abstract: PURPOSE:To obtain a vibration diaphragm which excles in the dynamic characteristics plus the water resistance and the heat resistance, by applying the pressure and heating process to a diaphragm made by mixing the natural fiber and the glass fiber with use of the thermosetting resin. CONSTITUTION:A mixture of 71.4wt% wood pulp and 8.6wt% bast fiber is beaten for 60min by a beating machine to be controlled to 25 deg. SR-28 deg. SR beating degree. Then 20wt% glass fiber having 2.45g/cm<3> density, a round section  and 5mm. length  is thrown into the beating machine to be split without imparing  the structure of the glass fiber. The beaten material is formed into a conical  shape by a paper making machine, and the paper is made through the paper making net. Then the pressing and heat drying are carried out at one time with  about 2kg/cm<2> pressing pressure to obtain a diaphragm cone. This cone is dipped into a binder made of thermosetting resin to ensure 30wt% content of resin and  then receives the pressure and heating process. In such way, a diaphragm having  a large E/P and excellent (f) properties is obtained.

Title: Wiper blade containing luminous material
Inventor: ZUKOSHI YASUHITO
IPC: B60S1/38
Filed: 1998-02-11
Abstract: PROBLEM TO BE SOLVED: To improve the safety of a vehicular running or stopping time by a light emitting operation by containing a luminous pigment to a composition whose main body is a silicone rubber. SOLUTION: A wiper blade 2 is molded by dispersing and kneading a filling material such as silica and a luminous pigment to the mixture of a vulcanization agent to a silicone rubber whose main component is a vulcanized silicone polymer, for example polyorganosiloxane. As the friction coefficient of the silicone rubber is higher than that of a natural rubber, the friction coefficient equal to the natural rubber is obtained by adjusting the kind and amount of an inorganic filling material. When a natural light and an artificial light is applied to the wiper blade 2, the luminous paint in the blade absorbs the light and the wiper blade 2 is floated up at the poor light amount place of the absorbed light.  By informing an inter-vehicle distance to a succeeding vehicle by a bright rear wiper and the position of a stopped vehicle whose light is turned off to an opposing vehicle by the lightening of a front wiper, the safety of a vehicular traffic at the running or stopping time can be contributed.

Title: Paper feed roller
Inventor: YOSHIURA TADASHI
IPC: B31B50/02
Filed: 1986-03-03
Abstract: PURPOSE:To obtain reliable transport force with good accuracy without slip by providing a rubber portion which is lined in a groove portion and ground with a metallic portion in such a manner as to project over the metallic portion. CONSTITUTION:A rubber portion 12 is formed by rubber line in a groove portion 13 of a roller 11. The rubber portion 12 is ground with a metallic portion of the roller 11. Therefore, the rubber portion 12 is deformed due to elasticity to have a large relief at the central part and have a small relief at a portion adhering to the metal, so that after grinding, the rubber portion is formed like a drum. As the rubber portion is thus pressed at the time of grinding and deformed to have a relief, the rubber portion is projected over the metallic surface 11a at the time of restoration. Accordingly, when a paper sheet is fed by the roller, the rubber portion is deformed to be in the same level with the metallic surface by pressing force to conduct paper feeding operation with high frictional force, and the paper feed is determined by the outside diameter of the metallic portion.

IPC: C21D9/28
Filed: 1988-02-29
Abstract: PURPOSE:To uniformly subject an uneven part to high frequency hardening and to prevent the deformation by hardening the uneven part by moving in the longitudinal direction of a shaft class by reducing the moving speed and rotary speed of a high frequency hardening unit or the shaft class. CONSTITUTION:The shaft class having the part on which a groove, recessed part, projecting part, etc., are formed in the longitudinal direction of a serration, spline, etc., and the part not formed is hardened by moving with its rotating. The moving speed and number of rotations of a high frequency hardening coil unit or the shaft class are reduced respectively compared with the moving speed and number of rotations of the part having no such parts at the part on which said groove, recessed part, projecting part, etc., are formed in said shaft class high frequency hardening method. The side face of the groove, recessed part, projecting part, etc., are thus hardened enough as well. As a result the shaft class is subjected to high frequency hardening without generating the variation in an over-pin diameter, the fall of a tooth, etc., on the serration, spline, etc., of the shaft class.
