  • Patent number: 10947146
    Abstract: Known heating burners for producing a welded joint between components of quartz glass include a burner head in which at least one burner nozzle is formed, a burner-head cooling system for the temperature control of the burner head and a supply line connected to the burner nozzle for a fuel gas. Starting from this, to modify a heating burner in such a way that impurities in the weld seam between quartz-glass components to be connected are largely avoided, it is suggested that the burner head should include a base body of silver or of a silver-based alloy.

  • 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: 10796926
    Abstract: In a method of manufacturing a glass interposer, first, stacked bodies formed on a front surface and a back surface of a glass substrate are processed along division lines (streets) to form first grooves having a first width and such a depth as not to reach the glass substrate, while leaving a residual resin portion at bottoms of the first grooves. Thereafter, the residual resin portion is subjected to ablation processing to expose the front surface and the back surface of the glass substrate, thereby forming second grooves having a second width narrower than the first width. A laser beam is applied along the division lines through the second grooves to form modified layers in the inside of the glass substrate, and an external force is exerted on the glass substrate to divide the glass substrate, with the modified layers as division starting points.
