Patent number: 9067756Abstract: A filament winding apparatus prevents a fiber bundle supplied to a liner from interfering with other fiber bundles and fiber supplying guides. First and second guide units include a plurality of fiber supplying guides arranged radially and extending and contracting in a direction approximately perpendicular to a liner central axis. When a fiber bundle supplied from a first supplying guide of the first guide unit crosses between a second supplying guide of the second guide unit and the liner, the distance from the second supplying guide to the liner central axis is made larger than the distance from the first supplying guide to the liner central axis, and in the reverse case, the distance from the first supplying guide to the liner central axis is made larger than the distance from the second supplying guide to the liner central axis.Type: GrantFiled: September 21, 2011Date of Patent: June 30, 2015Assignees: MURATA MACHINERY, LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Motohiro Tanigawa, Tadashi Uozumi, Daigoro Nakamura, Ken Hatta

Publication number: 20030116671Abstract: A drum type core comprises: a flanged cylinder including a cylinder portion with a coil wound thereon, and a flange portion connected integrally with one end of the cylinder portion; and a flange piece having on its one side an engaging hole, into which the other end of the cylinder portion of the flanged cylinder is inserted. The flanged cylinder and the flange piece are made of respective different materials. The flanged cylinder has a higher permeability and saturation flux density than the flange piece, while the flange piece has a higher surface electrical resistance than the flanged cylinder. The flanged cylinder is entirely coated with a heat-resisting epoxy resin except an outer side of the flange portion. The flange piece is provided with terminal pins, around which lead wires of the coil passing by the circumference of the flange piece are bound.Type: ApplicationFiled: December 9, 2002Publication date: June 26, 2003Applicant: MINEBEA CO., LTD.Inventor: Toshinori Okamoto
