Patent number: 9957187Abstract: A brittle plate processing method includes having a first portion of a brittle plate supported flat on a flat part of a support member that supports a first surface of the brittle plate, pressing a cutter against a second surface of the brittle plate opposite to the first surface, and forming a scribe line in the second surface of the brittle plate by moving the cutter and the support member relative to each other. In pressing the cutter, the cutter is pressed to a predetermined position on a second portion of the brittle plate other than the first portion. When the cutter is pressed to the predetermined position on the second portion of the brittle plate, the shape of the brittle plate due to bending deformation is defined by a defining part of the support member.Type: GrantFiled: June 8, 2016Date of Patent: May 1, 2018Assignee: Ashi Glass Company, LimitedInventors: Takashi Yamamoto, Toshiyuki Ishibashi, Mitsuhiko Endo, Masashi Kasajima

Patent number: 9822029Abstract: A method for processing a brittle plate includes a breaking step in which a pressing member for pressing a surface of the brittle plate and a support member for supporting a back face of the brittle plate are used to bend and deform the brittle plate and break the brittle plate along a score line formed on the surface of the brittle plate. The support member includes a flat portion that is arranged flat against one portion of the brittle plate to support the brittle plate, and a regulating portion that regulates a bending deformation shape of the brittle plate when the pressing member is pressed against a predetermined position of a remaining portion of the brittle plate. The breaking step includes breaking the brittle plate along the score line that is within the remaining portion of the brittle plate.Type: GrantFiled: June 14, 2016Date of Patent: November 21, 2017Assignee: Asahi Glass Company, LimitedInventors: Takashi Yamamoto, Toshiyuki Ishibashi, Mitsuhiko Endo, Masashi Kasajima

Patent number: 6136099Abstract: A rare earth-iron series magnet formed from an alloy ingot using a one-step hot working process is provided. The alloy ingot includes between about 8 and 30 atomic percent of at least one rare earth element, between about 2 and 28 atomic percent of boron, less than about 50 atomic percent of cobalt, less than about 15 atomic percent of aluminum and the balance of iron and other impurities that are inevitably included during the preparation process. The alloy is cast to obtain a cast ingot and the hot working is performed on the cast ingot at a temperature of greater than about 500.degree. C. in order to make the crystal grains of the ingot fine and to align the axis of the grains in a desired direction.Type: GrantFiled: March 19, 1993Date of Patent: October 24, 2000Assignee: Seiko Epson CorporationInventors: Koji Akioka, Tatsuya Shimoda, Toshiyuki Ishibashi, Ryuichi Ozaki, Osamu Kobayashi

Patent number: 5888416Abstract: The addition of a chelating agent or a chelating agent and an antioxidant in combination to a rare-earth bonded magnet composition and a rare-earth bonded magnet comprising a rare-earth magnetic powder and a resin component can provide improved moldability and magnets having high performance and high corrosion resistance. Further, the regulation of property values of the magnet composition enables the occurrence of troubles to be avoided during molding, resulting in improved productivity. Furthermore, the use of at least two resins as a resin component in an extruding composition contributes to improvement in moldability and consequently increase in throughput. Furthermore, the use of extrusion, involving setting by cooling, and not compression molding in the production of magnets can provide high-density, high-performance magnets.Type: GrantFiled: February 13, 1995Date of Patent: March 30, 1999Assignee: Seiko Epson CorporationInventors: Ken Ikuma, Toshiyuki Ishibashi, Koji Akioka
