Patent number: 9296649Abstract: A laminate which contains a transparent substrate, a unit layer formed on the transparent substrate, and a tin zinc oxide layer formed on the unit layer. The unit layer contains a dielectric layer, a metal layer, a barrier layer, and a dielectric layer in this order starting from the transparent substrate side, and the dielectric layers contain substantially no carbon. The tin zinc oxide layer contains an oxide of tin and zinc as the main component and further contains carbon in an amount of at least 0.1 atomic % to the total amount of tin and zinc.Type: GrantFiled: August 28, 2014Date of Patent: March 29, 2016Assignee: Asahi Glass Company, LimitedInventors: Jun Okawa, Kazuya Yaoita

Publication number: 20140363685Abstract: To provide a production process to produce a laminate having excellent moisture resistance and abrasion resistance, and a laminate. The process for producing a laminate 1 comprises a first step of forming a dielectric layer 121, a metal layer 122 and a dielectric layer 121 in this order on a transparent substrate, and a second step of, after the first step, forming a tin zinc oxide layer 13 containing an oxide of tin and zinc as the main component. Formation of the tin zinc oxide layer 13 in the second step is carried out by sputtering using a metal target containing tin and zinc as the main component in a gas atmosphere in which a gas containing carbon atoms substantially functions as an oxidizing gas. Formation of the dielectric layer 121 in the first step is carried out in a gas atmosphere in which a gas containing no carbon atom substantially functions as an oxidizing gas.Type: ApplicationFiled: August 28, 2014Publication date: December 11, 2014Applicant: ASAHI GLASS COMPANY, LIMITEDInventors: Jun OKAWA, Kazuya Yaoita

Patent number: 5671569Abstract: In a multi-storied frame building, a controlled frame member having means to damp seismic forces of deformation. A first vertical wall column has a top connected to a horizontal wall girder overhanging the wall column. A second wall column is erected in vertical alignment beneath the tip end of the wall girder co-planar with, but spaced from, the first wall column. A seismic response control apparatus connected between the tip end of the wall girder and the top of the second wall column generates damping force when the tip end of the wall girder and the top of the second wall column are displaced relative to each other. Additional girders are arranged on lower stories of the building as required to further strengthen the building against seismic deformation.Type: GrantFiled: November 29, 1995Date of Patent: September 30, 1997Assignee: Kajima CorporationInventors: Takuji Kobori, Yukihiro Omika, Masayuki Nagata, Jun Okawa, Yukimasa Yamamoto
