Patent number: 8381547Abstract: An air-cooling/tempering apparatus and method, which can properly temper a glass sheet bent to have a complexly curved surface, without increasing the heating temperature of the glass sheet or increasing a wind pressure from air-blowing openings. A lower blowing member of the air-cooling/tempering apparatus includes a plurality of blade-shaped members arranged into a combtooth shape each having a front end face provided with a plurality of arranged air-blowing openings. Each blade-shaped member has a front end face with a concave curve so that a gap from the plurality of airblowing openings to the bent glass sheet becomes substantially uniform. The arrangement of air-blowing openings provided on the front end face of each blade-shaped member is turned with a predetermined angle and extends in one direction in each side portion in plan view.Type: GrantFiled: March 9, 2011Date of Patent: February 26, 2013Assignee: Asahi Glass Company, LimitedInventors: Masao Fukami, Shinya Ota, Yutaka Kitajima

Patent number: 5152857Abstract: In a method for preparing a substrate for semiconductor device, the substrate is prepared either by directly bonding a bonding wafer to a base wafer or by bonding the bonding wafer to the base wafer with an oxide film formed on at least the bonding surface of the bonding wafer or the bonding surface of the base wafer to make finished semiconductor devices with an SOI structure. Prior to the bonding operation, the bonding wafer and the base wafer are subjected to the steps of (1) making the diameter of the bonding wafer smaller than the diameter of the base wafer, (2) setting the beveling width of the back side (bonding side) of the bonding wafer at 50 microns or less, and (3) beveling the front side of said base wafer so that the bonding surface of the base wafer is equal in size to the bonding surface of the bonding wafer.Type: GrantFiled: March 21, 1991Date of Patent: October 6, 1992Assignee: Shin-Etsu Handotai Co., Ltd.Inventors: Tatsuo Ito, Atsuo Uchiyama, Masao Fukami
