Abstract: This windshield comprises: a first glass panel having a first surface and a second surface; a second glass panel having a third surface and a fourth surface; and an intermediate film that is disposed between the first glass panel and the second glass panel, and that joins the second surface of the first glass panel to the third surface of the second glass panel. The failure stress of at least one region of the glass panel which is the inner panel is configured so as to be less than the failure stress of another region.

Abstract: The present invention is a method for reducing warpage of a glass sheet produced by a float process. This warpage occurs due to chemical strengthening treatment of the glass sheet. In the method of the present invention, a glass sheet produced by a float process is maintained in a temperature range from a temperature 70° C. lower than a strain point of the glass to a temperature 20° C. higher than the strain point for at least 10 minutes before the glass sheet is subjected to chemical strengthening treatment.

Abstract: The present invention is directed to a windshield including a first glass plate that includes a first surface and a second surface, a second glass plate that includes a first surface and a second surface and is arranged such that the first surface of the second glass plate faces the second surface of the first glass plate; and an intermediate film that includes a first surface and a second surface and is sandwiched between the first glass plate and the second glass plate. The first glass plate and the second glass plate each include a first end portion and a second end portion that is opposite to the first end portion. The intermediate film includes a first end portion and a second end portion that is opposite to the first end portion.

Abstract: The glass sheet of the present invention is a glass sheet with a thickness of 1.6 mm or less produced by a float process in which a molten glass material is formed into a sheet on a molten metal. When one surface of the glass sheet kept in contact with the molten metal during the formation of the molten glass material into the glass sheet is defined as a first surface and the other surface of the glass sheet opposite to the first surface is defined as a second surface, at least the first surface has been subjected to a treatment for forming a densified dealkalized layer therein. An etching rate ER1 (nm/min) of the first surface and an etching rate ER2 (nm/min) of the second surface satisfy a relation of ER2/ER1≦0.8 when the first surface and the second surface are etched using 0.1 mass % hydrofluoric acid at 50° C. as an etching liquid.
Abstract translation: 本发明的玻璃板是将熔融玻璃材料形成为熔融金属的片材的浮法法制成的厚度为1.6mm以下的玻璃板。 在将熔融玻璃材料形成玻璃板期间保持与熔融金属接触的一个表面定义为第一表面，将与第一表面相对的玻璃板的另一个表面定义为第二表面 至少第一表面已经被处理以在其中形成致密化的脱碱层。 当第一表面和第二表面被蚀刻时，第一表面的蚀刻速率ER1（nm / min）和第二表面的蚀刻速率ER2（nm / min）满足关系ER2 / ER1＆nlE; 0.8， 氢氟酸在50℃作为蚀刻液。
