Glass () for vehicles includes a light blocking region (A) in which a far-infrared ray transmission region (B) provided with an opening and a far-infrared ray transmission member arranged in the opening, and a visible light transmission region (C) transmitting visible light are formed. The opening is formed between an upper edge part () of the glass () and a first position (P) in a first direction from the upper edge part () toward a lower edge part () of the glass (), the first position (P) is a position at which a distance from the upper edge part () is 30% of a length from the upper edge part () to the lower edge part (), and between a second position (P) and a third position (P) in a second direction from a side edge part () toward a side edge part () of the glass () for vehicles. A length (L) in the second direction from the second position (P) to the third position (P) is 55% of a length (L) from the side edge part () to the side edge part (), and a length of the longest straight line among straight lines connecting optional two points within a surface on a vehicle exterior side is equal to or smaller than 80 mm.

Glass for vehicles and camera unit

To provide laminated glass excellent in the quality and the cost, in which two glass plates differing in the plate thickness can easily be bent with good accuracy. Laminated glasscomprising a plurality of glass platesandbent into a predetermined shape, and an interlayerinterposed between the plurality of glass platesand, at least two glass platesandamong the plurality of glass platesanddiffering in the plate thickness, wherein the two glass platesanddiffering in the plate thickness have different glass compositions, and at an optional temperature between the annealing point and the softening point of the thick glass plate, the thick glass platehas a lower viscosity than the thin glass plate

Laminated glass and its production process

In a preliminary forming step, positioning of a glass sheet is facilitated, and generation of a hinge mark by a flapping mechanism and generation of excessively bent portions, are prevented at the same time.

Bending method for a glass plate and bending apparatus for a glass plate

The present invention relates to an apparatus for bending a glass sheet and a method for bending a glass sheet including an apparatus and a method for conveying a glass sheet, and it aims at producing with good efficiency a glass sheet of high quality, having complicated configuration. The method for bending a glass sheet comprises a step of placing a heated glass sheet on an inner mold with a tilting mechanism arranged at an inner side of a forming ring with a tilting mechanism, the forming ring being provided with a fixed frame and a movable frame, to thereby preform the glass sheet, a step of transferring the glass sheet preformed on the inner mold with a tilting mechanism onto the forming ring with a tilting mechanism and a step of pressing the glass sheet with a predetermined forming plane of the forming ring and tilting the movable frame, wherein the step of preforming the glass sheet includes a step of preforming the glass sheet placed on the inner mold by tilting a movable frame of inner mold pivoted at an end of a fixed frame of inner mold provided in the inner mold.

Method for bending a glass sheet and apparatus for bending a glass sheet

An air-cooling/tempering apparatus and method, which can properly temper a glass sheet bent to have a complexly curved surface, without increasing the heating temperature of the glass sheet or increasing a wind pressure from air-blowing openings. A lower blowing member of the air-cooling/tempering apparatus includes a plurality of blade-shaped members arranged into a combtooth shape each having a front end face provided with a plurality of arranged air-blowing openings. Each blade-shaped member has a front end face with a concave curve so that a gap from the plurality of airblowing openings to the bent glass sheet becomes substantially uniform. The arrangement of air-blowing openings provided on the front end face of each blade-shaped member is turned with a predetermined angle and extends in one direction in each side portion in plan view.

Air-cooling/tempering apparatus for glass sheet, and air-cooling/tempering method

It is an object of the present invention to provide a method for bending a glass sheet which can appropriately prevent cloth mark due to suctioning. The present invention is characterized by a method for bending a glass sheet comprising a heating step for heating a glass sheet to soften the glass sheet, and a bending step for bending the heated and softened glass sheet to have a predetermined shape, wherein the bending step comprises a step of pressing the heated and softened glass sheet, whose edges are supported by a supporting frame, against a forming surface of a bending mold opposed to the supporting frame, and a vacuum forming step for providing a negative pressure through a plurality of suction holes formed on the forming surface so that the shape of the pressed glass sheet is bent along the forming surface of the mold, and wherein in the vacuum forming step, the plurality of suction holes are grouped into at least two groups, and the raised negative pressures for the respective groups are lowered at different timings.
