  • Publication number: 20220170313
    Abstract: Provided are a glass panel unit and a method for manufacturing the glass panel unit, both of which are designed to overcome the problem of poor handleability of known glass panel units with no through holes. A glass panel unit includes a first panel, a second panel, a seal, and a boundary wall. The seal has a frame shape and hermetically bonds respective peripheral edge portions of the first panel and the second panel. The boundary wall partitions an internal space into a first space as a hermetically sealed evacuated space and a second space spatially separated from the first space. The first panel has a first through hole provided through a portion, corresponding to the second space, of the first panel. The second panel has a second through hole provided through a portion, corresponding to the second space and facing the first through hole, of the second panel.

  • Patent number: 11268317
    Abstract: A first substrate, having an evacuation port, and a second substrate are bonded together with a first sealing material in a frame shape interposed between them to create an internal space. The internal space is evacuated through the evacuation port, and the evacuation port is sealed up with the internal space kept evacuated. At this time, a second sealing material inserted into the evacuation port is heated and melted while being pressed toward the second substrate such that the evacuation port is sealed up with the second sealing material melted. The evacuation port and the second sealing material have dissimilar shapes when viewed along the center axis of the evacuation port in a state where the second sealing material has been inserted into the evacuation port but has not melted yet.

  • Patent number: 11148971
    Abstract: A gas adsorption unit includes a getter, a package encapsulating the getter, and a low-melting member. The low-melting member is heated, and thereby melted, at a temperature lower than a melting point of the package to bond a connector including the low-melting member onto the package. Next, the low-melting member that has melted is cooled and cured. Then, thermal stress resulting from a difference in thermal expansion coefficient between the package and the connector is caused to the package connected to the connector, thereby breaking the package open.

  • Publication number: 20210270084
    Abstract: A method for manufacturing a glass panel unit includes an assembling step, a bonding step, a gas exhausting step, a sealing step, and an activating step. The bonding step includes melting a peripheral wall in a baking furnace at a first predetermined temperature to hermetically bond a first glass pane and a second glass pane together with the peripheral wall thus melted. The gas exhausting step includes exhausting a gas from an internal space through an exhaust port in the baking furnace to turn the internal space into a vacuum space. The sealing step includes locally heating to a temperature higher than a second predetermined temperature, and thereby melting, either a port sealing material or an exhaust pipe to seal the exhaust port and thereby obtain a work in progress. The activating step includes activating a gas adsorbent after the sealing step to obtain a glass panel unit.
