Publication number: 20150030789Abstract: A vacuum insulating glazing includes first and second glass substrates that are stacked with a gap set at a pressure less than an atmospheric pressure, and the gap is sealed peripherally by a sealing. The sealing includes a metal component and a glass layer that bonds the metal component and the glass substrates. A material for the metal component is selected from materials whose tensile strength X (N/mm2) and breaking elongation Y (%) satisfy a relationship Y?0.10X by a room temperature tensile test (tensile speed: 1 mm/min) that is performed after the materials are kept at 490° C. for 40 minutes in an atmosphere.Type: ApplicationFiled: October 13, 2014Publication date: January 29, 2015Applicant: ASAHI GLASS COMPANY, LIMITEDInventors: Syuji MATSUMOTO, Mika Yokoyama

Patent number: 7712333Abstract: To provide a method for smoothing a surface of a glass substrate having a concave defect, such as a pit or a scratch. A method for smoothing a surface of a glass substrate having a concave defect thereon, comprising: forming a film on the surface of the glass substrate having the concave defect by a dry deposition method, the film comprising a glass material having a fluid point Tf of 150° C. or above and of not higher than a strain point Ts (° C.) of the glass substrate; and heating the film of the glass material at a temperature of not lower than Tf and not higher than Ts to put the film in such state that the film of the glass material can flow so as to bury the concave defect, followed by cooling the film of the glass material, thereby to smooth the surface of the glass substrate having the concave defect.Type: GrantFiled: March 29, 2006Date of Patent: May 11, 2010Assignee: Asahi Glass Company, LimitedInventors: Toshiyuki Uno, Yoshiaki Ikuta, Mika Yokoyama, Ken Ebihara
