Publication number: 20230293859Abstract: A guide wire includes a core shaft and a twisted wire coil body having a plurality of wires twisted together and arranged along an outer periphery of the core shaft. The twisted wire coil body includes a distal end portion including a distal end and a feature portion, and a proximal end portion, and has a smaller outer diameter in the feature portion than at the proximal end portion. Among the plurality of wires, an outermost wire having a longest distance to a center point of the core shaft in a transverse cross section of the twisted wire coil body in the feature portion, has a smaller cross-sectional area than a wire having a longest distance to the center point in a transverse cross section of the twisted wire coil body at the proximal end portion. An inner diameter of the twisted wire coil body is constant.Type: ApplicationFiled: May 24, 2023Publication date: September 21, 2023Applicant: Asahi Intecc Co., Ltd.Inventor: Fumitaka SATOH

Patent number: 5441312Abstract: A pipe joint for connecting a flexible corrugated tube includes a joint body, a sleeve received in an axial through bore in the joint body for holding a free end of the flexible corrugated tube, and a nut threadedly fitted in a threaded portion of the joint body. A shoulder is formed on an inner surface of the through bore, and has an air-tight surface directed toward one end of the through bore. A tapering surface, decreasing in diameter progressively toward the shoulder, is formed on the inner surface of the through bore in adjacent relation to the shoulder. An annular groove of a generally channel-shaped cross-section is formed in the inner surface of the through bore in adjacent relation to the tapering surface. The sleeve has projections extending radially inwardly from one end thereof facing said shoulder, the sleeve having an end surface at the other end thereof.Type: GrantFiled: September 30, 1994Date of Patent: August 15, 1995Assignees: Hitachi Metals, Ltd., Tokyo Gas Co., Sanko Gas Seiki, Ltd.Inventors: Minoru Fujiyoshi, Michio Hasegawa, Shinichi Kanomata, Takashi Anamizu, Morio Saito, Fumitaka Satoh

Patent number: 4306056Abstract: Processes for producing an oligoester and producing unsaturated polyester resin by use of the oligoester using unsaturated dibasic acid or its anhydride and isophthalic acid as dibasic acid components, and propylene oxide as a polyol component, characterized by (a) the step of reacting isophthalic acid with propylene oxide in the presence of an amine compound catalyst to form an oligoester, (b) the step of removing volatile components from the oligoester by heating it at a temperature range of 180.degree.-300.degree. C., (c) the step of treating the resulting oligoester with silica-alumina compound having adsorbing property, and (d) the step of reacting the oligoester so treated with the unsaturated dibasic acid or its anhydride.Type: GrantFiled: May 16, 1980Date of Patent: December 15, 1981Assignee: Mitsubishi Gas Chemical Company, Inc.Inventors: Akira Miyamoto, Senzo Shimizu, Fumitaka Satoh, Yasumitsu Higuchi, Toshiyuki Abe, Kohji Yamamoto
