Patent number: 8104385Abstract: The brittle workpiece splitting system 1 includes a substrate holding mechanism 10 for holding a substrate 51, and a processing unit 5 for splitting the substrate 51 held by the substrate holding mechanism 10 by a splitting process. The substrate holding mechanism 10 has an edge damper 12 adapted to clamp an edge part of the substrate 51 from the sides of the opposite surfaces of the edge part, and support members 19 for supporting the substrate 51 thereon at a predetermined height. The support members 19 are disposed on the side opposite the side of the edge damper 12 with respect to the intended split line 61 parallel to the edge part of the substrate 51. The edge damper 12 has an edge holder 15 on which the substrate 51 is seated, and a pressure bar 14 for pressing the substrate 51 against the edge holder 15 to hold the substrate 51 between the edge holder 15 and the pressure bar 14.Type: GrantFiled: October 7, 2005Date of Patent: January 31, 2012Assignees: Shibaura Mechatronics Corporation, Kabushiki Kaisha ToshibaInventors: Masakazu Hayashi, Shinji Nakata, Susumu Yahagi

Patent number: 5038950Abstract: A laser beam type working apparatus and method are disclosed which join together metal conductors formed as an alternate layer structure over a surface side of a light-transmitting substrate with an interposing electrical insulator provided therebetween. The joining together of these metal conductors in achieved by directing a laser beam from a rear-surface side of the substrate to an underlying metal conductor to melt it so that it flows out upwardly in a molten state so that the underlying metal conductor is connected to an overlying metal conductor.Type: GrantFiled: July 10, 1990Date of Patent: August 13, 1991Assignee: Kabushiki Kaisha ToshibaInventor: Susumu Yahagi

Patent number: 5017755Abstract: An apparatus for repairing a liquid crystal display comprises a common electrode, pixel electrodes facing the common electrode, and a liquid crystal sealed between the common and pixel electrodes. If the liquid crystal contains foreign matter which short-circuits the common and pixel electrodes to each other, a pixel electrode is irradiated with a laser beam such that at least a ring line region completely surrounding a portion touching the foreign matter is burnt away, whereby a region inside of the ring line region and a region outside of the ring line region are electrically insulated from each other.Type: GrantFiled: October 20, 1989Date of Patent: May 21, 1991Assignee: Kabushiki Kaisha ToshibaInventors: Susumu Yahagi, Shuichi Ishida, Shigeru Fujimoto
