摘要:
A bent glass sheet shaping method which is capable of reducing occurrence of visibility distortions and a bent glass sheet with reduced visibility distortions. A glass sheet is heated to a shapeable temperature, a cover material is mounted onto a press die such that a direction of waves in the cover material is diagonal to a direction of distortions in the glass sheet, and the heated glass sheet with the press die is pressed.

摘要:
A metal fixture-joined glass article which has on at least part of the surface of the glass article a conductive film formed by baking silver paste containing Ag particles and glass frit, wherein metal-fixture joined surfaces are fixed to the conductive film by an unleaded solder alloy mainly containing Sn, and the unleaded solder alloy contains at least 1.5 mass% of Ag, whereby lowering in the appearance and the joint strength of the conductive film is restricted. When a metal fixture having at least two joined surfaces is used, a total area of joined surfaces is at least 37 mm2 and up to 50 mm2 to provide a high joining strength between the glass article and the metal fixture even if unleaded solder alloy is used. A volume of unleaded solder alloy at each joined surface set to 1.0-2.0 times the product of the applicable joined surface area and a unleaded solder alloy thickness can restrict cracks from occurring in a glass article.
摘要:
A ceramic paste is applied to a first glass sheet (11), and a ceramic paste is applied to a second glass sheet (13) with a lower solar absorptivity than that of the first glass sheet (11). In this case, the amount per unit area of the ceramic paste to be applied to the first glass sheet (11) is allowed to be smaller than that of the ceramic paste to be applied to the second glass sheet (13). Alternatively, a first ceramic paste and a second ceramic paste are allowed to have different compositions from each other. The first glass sheet (11) and the second glass sheet (13) are bent so that the surfaces onto which the ceramic pastes have been applied are shaped as concave surfaces. The applied ceramic paste is fired using the heating used for bending. Thus maskings (12) and (14) are formed. The first glass sheet (11) and the second glass sheet (13) are bonded to each other, with a resin interlayer film (15) being interposed therebetween.
