Patent number: 8820729Abstract: When a rare earth magnet block is cut or ground by a cutting or grinding tool, a jig is used for holding the magnet block in place. The jig comprises a base, a pair of metal support members disposed on opposite sides of the base and provided with grooves, and rubber rods received in the support member grooves such that the rubber rod partially protrudes from the groove and abuts on the groove bottom. The magnet block is rested on the base and clamped between the rubber rods. The volume of the groove is larger than the volume of the rubber rod.Type: GrantFiled: June 22, 2012Date of Patent: September 2, 2014Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Yuhito Doi, Takayuki Hasegawa, Takaharu Yamaguchi, Takehisa Minowa

Patent number: 8753174Abstract: In a method for multiple cutoff machining a rare earth magnet block, a cutting fluid feed nozzle having a plurality of slits is combined with a plurality of cutoff abrasive blades coaxially mounted on a rotating shaft, each said blade comprising a base disk and a peripheral cutting part. The slits in the feed nozzle into which the outer peripheral portions of cutoff abrasive blades are inserted serve to restrict any axial run-out of the cutoff abrasive blades during rotation. Cutting fluid is fed from the feed nozzle through slits to the rotating cutoff abrasive blades and eventually to points of cutoff machining on the magnet block.Type: GrantFiled: January 30, 2013Date of Patent: June 17, 2014Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Koji Sato, Takehisa Minowa, Takaharu Yamaguchi, Takayuki Hasegawa, Kazuhito Akada

Patent number: 8739372Abstract: The invention provides a fastener stringer for a hidden slide fastener. Each of the fastener tapes includes a main tape body, a folded tape portion which is folded into a U-shape, and an element attaching portion. The folded tape portion includes at least two multiple-weave portions in which warp yarn forms a multiple-weave structure, and a single-weave portion arranged at least at one location of an intermediate portion of the folded tape portion. According to this, it is possible to enhance rigidity of the folded tape portion in a lateral direction of a tape, and to prevent a position of the warp yarn from being misaligned at the multiple-weave portion. Therefore, hiding performance of the hidden slide fastener can be enhanced.Type: GrantFiled: September 4, 2009Date of Patent: June 3, 2014Assignee: YKK CorporationInventors: Takayuki Hasegawa, Akira Takano, Masashi Doi

Patent number: 8702084Abstract: A magnet holding jig comprises a platform and first and second holders disposed on opposite sides of the platform. The platform is provided with channels, the holders are comb-shaped to define digits and slits, the channels and the slits being aligned to define guide paths for permitting entry of a cutting tool therein, and the holders are also configured as digitate hooks. The holder hooks are in contact with a rare earth magnet block resting on the platform. The holders are pushed inward at their lower portions so as to bring each hook digit of the second holder in pressure abutment with the magnet block at a higher level than each hook digit of the first holder for thereby holding the magnet block in place on the platform.Type: GrantFiled: January 5, 2011Date of Patent: April 22, 2014Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Yuhito Doi, Takehisa Minowa, Takayuki Hasegawa, Takaharu Yamaguchi, Koji Sato
