  • Patent number: 11814729
    Abstract: A method for manufacturing a glass article includes a heating step that heats a heating object made of glass. The heating step includes heating the heating object by converting, by a converter arranged between the heating object and a radiant heat source that radiates infrared light, a spectrum of the infrared light radiated from the radiant heat source and causing the heating object to absorb the infrared light radiated from the converter. The converter includes: an infrared light absorber that generates heat by absorbing the infrared light radiated from the radiant heat source; and an infrared light radiator made of a silicon-containing material. The infrared light radiator is heated through thermal conduction from the infrared light absorber. At least part of a surface of the converter facing the heating object includes at least part of a surface of the infrared light radiator.

  • Publication number: 20220043184
    Abstract: In order to achieve both an anti-glare effect and a sparkle-suppressing effect in a transparent article having an anti-glare surface having a recess and protrusion structure, the transparent article has an anti-glare surface having a recess and protrusion structure. The recess and protrusion structure of the anti-glare surface has a 6-20 ?m cycle length obtained from the autocorrelation function.

  • Patent number: 9995852
    Abstract: Provided is a cover member for an exhibit or display element which makes an exhibit or display element visible as if nothing existed between the exhibit or display element and the viewer and can protect the exhibit or display element. The cover member (3) for an exhibit or display element includes a transparent substrate (31a) and an antireflection film (31b) formed on at least one surface of the transparent substrate. The cover member (3) for an exhibit or display element has a luminous reflectance of 0.5% or less.

  • Patent number: 9463998
    Abstract: A method for manufacturing a film-coated glass film includes heating a cylindrical body made of glass or ceramic with a heater provided in an interior of the cylindrical body, heating a glass film by feeding the glass film over the heated cylindrical body, and forming a film made of an oxide, a nitride, or a metal on the glass film while the film is on and being heated by the cylindrical body.

  • Patent number: 8910845
    Abstract: Provided is a method for cutting a glass sheet whereby even a thin glass sheet having a thickness of 1 mm or less can be suitably cut. A nick (20a) is formed on a section of a planned cutting line (L) of a glass sheet (20). The glass sheet (20) is placed on a surface (10a) of a jig (10) in which an uneven portion (10b) having a shape corresponding to the planned cutting line (L) is formed. The glass sheet (20) is cut by deforming a portion thereof located above the uneven portion (10b) and developing a crack originating from the nick (20a).
