An adhesive agent is layered on the outer periphery of the protective sheath front end so as to cover the filamentous member. A ring member is fitted to the protective sheath front end so as to cover the adhesive agent. The inner surface of the ring member is bonded to the filamentous member with the adhesive agent therebetween.Type: GrantFiled: September 14, 2010Date of Patent: June 10, 2014Assignee: Hoya CorporationInventor: Tsuyoshi Furuta

Publication number: 20140138947Abstract: A method of manufacturing at least one flange (1a, 1b) by first rotating a tubular element (30) and two sheet elements (10, 20) with respect to one another until a radially enlarged portion (11) and adjacent hub section (21a,b) have been formed on the tubular element. The sheet element is impregnated by a thermosetting resin. When the resin has cured, the radially enlarged portion (11) is cut along a cut line (S), thereby also dividing the tubular element (30) in two parts (30a, 30b) and generating at least a first flange (1a) having a first flange section (11a) and a first hub section (21a). Optionally, a second flange (1b) having a second flange section (11b) and a second hub section (21b), is generated. In a preferred embodiment, the cut line (S) is arranged in the middle of the radially enlarged portion (11), whereby two similar flanges (1a, 1b) are generated.Type: ApplicationFiled: November 21, 2013Publication date: May 22, 2014Applicant: Flowtite Technology ASInventors: Gudmundur PALSSON, Tomas ANDERSSON

Publication number: 20140131365Abstract: This high pressure gas tank is a tank in which a fiber-reinforced resin layer is formed around an outer periphery of a tank liner by fibers impregnated with thermosetting resin being wound around the outer periphery of the tank liner. The fiber-reinforced resin layer includes an inside layer formed on the tank liner side, and an outside layer formed on an outer periphery of the inside layer. The inside layer is formed as a dense layer, while the outside layer is formed as a layer that is less dense than the inside layer by forming a larger number of airspaces in the outside layer than there are in the inside layer.Type: ApplicationFiled: June 28, 2012Publication date: May 15, 2014Applicants: NIPPON SOKEN, INC., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shinji Miyoshi, Kentaroh Hioki
