  • Patent number: 10974985
    Abstract: A glass panel unit manufacturing method includes a bonding step, a pressure reducing step, and a sealing step. The bonding step includes bonding together a first substrate and a second substrate with a first sealant to create an inner space. The pressure reducing step includes producing a reduced pressure in the inner space through an exhaust port that the first substrate has. The sealing step includes melting and expanding a second sealant, inserted into the exhaust port, by heating the second sealant and thereby sealing the exhaust port up with the second sealant expanded to the point of coming into contact with a dam arranged in the inner space.

  • Patent number: 10829984
    Abstract: A method for making a vacuum insulated glass window assembly is provided in which an amount of wet frit material is applied to a lower portion of a pump-out tube prior to insertion of the tube into a hole formed in a glass substrate of the VIG window assembly. The tube is then inserted into the hole, frit paste end first. An amount of frit may overflow the hole and form a bump/shoulder of frit material proximate the area of the hole on an outer surface of the glass substrate. Applying the fit to the tube prior to insertion and at a lower portion thereof reduces the amount of and/or avoids residual frit being deposited in an area of the tube that might significantly interfere with subsequent sealing processes, such as, for example, laser sealing of the pump-out tube.

  • Patent number: 10465433
    Abstract: Certain example embodiments of this invention relate to vacuum insulating glass (VIG) units having improved seals made using two different frit-based edge seal materials, and/or methods of making the same. In certain example embodiments, a first frit material is applied around peripheral edges of first and second glass substrates. The first frit material, which may be bismuth-based in certain example embodiments, is fired with a heat treatment (e.g., thermal tempering) process. A second frit material, which may be VBZ-based in certain example embodiments, is applied and at least partially overlaps with the fired first frit material. The first frit material acts as a primer, and the second frit material helps seal together the VIG unit. The second frit material is fired at a significantly lower temperature that enables the glass to retain the temper or other strength imparted by the heat treatment.

    Abstract: Vacuum-insulated glass (VIG) windows (10) that employ glass-bump spacers (50) and two or more glass panes (20) are disclosed. The glass-bump spacers are formed in the surface (24) of one of the glass panes (20) and consist of the glass material from the body portion (23) of the glass pane. Thus, the glass-bump spacers are integrally formed in the glass pane, as opposed to being discrete spacer elements that need to be added and fixed to the glass pane. Methods of forming VIG windows are also disclosed. The methods include forming the glass-bump spacers by irradiating a glass pane with a focused beam (112F) from a laser (110). Heating effects in the glass cause the glass to locally expand, thereby forming a glass-bump spacer. The process is repeated at different locations in the glass pane to form an array of glass-bump spacers. A second glass pane is brought into contact with the glass-bump spacers, and the edges (28F, 28B) sealed.

    Abstract: A method for constructing a mirror blank, including arranging hollow glass balls, on a front face sheet, and in close proximity to each other to permit fusing upon expansion; restricting the expansion of the hollow glass balls with a bounding structure during expansion of the hollow glass balls to force the hollow glass balls into a densely packed array of cells; applying heat to soften the hollow glass balls and increase the pressure within the hollow glass balls as the hollow glass balls fuse with each other during expansion, forming cells, wherein as a result of fusing, the hollow glass balls contact the front face sheet as a result of the increased pressure within the hollow glass balls; annealing and cooling the mirror blank to below annealing temperature associated with the hollow glass balls; and venting the cells.

  • Patent number: 6874335
    Abstract: Systems and methods for large scale synthesis of germanium selenide glass and germanium selenide glass compounds are provided. Up to about 750 grams of a germanium selenide glass or a glass compound can be synthesized at a time in about eight hours or less. Stoichiometrically proportional amounts of germanium and selenium are placed in an ampoule. A variable may also be placed in the ampoule. The ampoule is heated to above the softening temperature of the glass or glass compound being synthesized. The ampoule is then rocked for a period of time while the temperature is held constant. The temperature of the ampoule is then brought down to above the softening temperature of the glass or glass compound being synthesized and then quenched.

  • Patent number: 6623593
    Abstract: A funnel-shaped chip tube and a tubular-shaped press frit are prepared. After the chip tube is disposed on a major surface of a substrate so that the center axis of an exhaust hole provided in the substrate of a sealed container body and the center axis of the chip tube may substantially coincide with each other, the press frit is so disposed as to be located on a surface of an opening portion. After that, by heating the whole device, the press frit is heated and melted, to provide a sealing member contiguously from an outer-rim outside portion of the flare-shaped opening portion of the chip tube to a portion of a tubular portion beyond a boundary.
