  • Patent number: 11065943
    Abstract: Provided are a vehicle windshield equipped with a transparent film at a visual field area, where a negative effect on a driving visibility due to a boundary line between a forming area and a non-forming area of the transparent film is improved, and a vehicle component having the vehicle windshield. The vehicle windshield includes: a window plate; and a transparent film provided at a surface on a vehicle-interior side of the window plate, wherein the vehicle windshield includes a first area where the transparent film is not provided and a second area where the transparent film is provided, at a central area when viewed from a front side, and a boundary between the first area and the second area has no perspective distortion and is constituted by a boundary line having line width visually recognized by scattering of irradiated light of 10 ?m to 200 ?m.

  • Patent number: 9296649
    Abstract: 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.

  • Publication number: 20140363685
    Abstract: 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.

  • Patent number: 5671569
    Abstract: 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.
