Abstract: A glass panel unit includes: a first substrate including a first glass panel; a second substrate including a second glass panel; and a frame-shaped sealing portion that is hermetically bonded to the first substrate and the second substrate. The sealing portion creates an evacuated space between the first substrate and the second substrate. When viewed from a region where the second substrate is positioned with respect to the first substrate, the first substrate includes a part arranged to stick out of an edge of the second substrate. The part includes a mounting portion used to mount the glass panel unit onto a vehicle.

Abstract: A method for manufacturing a glass panel unit includes an assembling step, a gas exhausting step, and a sealing step. At least one of a first glass pane or a second glass pane includes a low-emissivity film. In a situation where the low-emissivity film is heated at a temperature increase rate of 4° C./min before a peripheral wall is melted, a ratio of an emission quantity of a rare gas emitted from the low-emissivity film at a deformation temperature of the partition to an emission quantity of the rare gas emitted from the low-emissivity film at 100° C. is equal to or less than 2.0.

Abstract: A glass panel unit manufacturing method includes a bonding step, an insertion step, an evacuation step, and a sealing step. The bonding step includes bonding a first substrate having an evacuation port and a second substrate with a bonding material having a frame shape to form an internal space. The insertion step includes inserting a sealing material into the evacuation port. The evacuation step includes evacuating the internal space by connecting an exhaust device to the evacuation port and driving the exhaust device. The sealing step includes sealing the evacuation port with the sealing material while an evacuated state in the internal space is maintained. In the sealing step, a measured value by a pressure gauge is monitored while the sealing material is heated, softening of the sealing material is detected based on the transition of the measured value, and heating of the sealing material is stopped.

Abstract: A pillar delivery method is a method for delivering a plurality of pillars onto a substrate, including a glass panel, to manufacture a glass panel unit. The pillar delivery method includes an irradiation step, a holding step, and a mounting step. The irradiation step includes setting, over a holder, a sheet for use to form pillars and irradiating the sheet with a laser beam to punch out the plurality of pillars. The holding step includes having the plurality of pillars, which have been punched out of the sheet, held by the holder. The mounting step includes picking up some or all of the plurality of pillars from the holder and mounting the pillars onto the substrate.

Abstract: A method for manufacturing a glass panel unit includes an adhesive disposing step, a glass composite generation step, an internal space forming step, an evacuation step, and an evacuated space forming step. The adhesive disposing step includes disposing a thermal adhesive on a second panel. The glass composite generation step includes generating a glass composite including a first panel, the second panel, and the thermal adhesive. The internal space forming step includes heating the glass composite to melt the thermal adhesive to form internal spaces (a first space and a second space). The evacuation step includes exhausting gas from the internal space to evacuate the internal space. The evacuated space forming step includes heating and applying force to part of a first portion or a second portion to deform the part to close an evacuation path to form an evacuated space hermetically closed.

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 including a wired glass pane and a second substrate including a non-wired glass pane with a first sealant in a frame shape 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 irradiating the second sealant with an infrared ray externally incident through the second substrate to seal the exhaust port up with the second sealant that has melted.

Abstract: A glass panel unit assembly includes: glass substrates; a peripheral wall having a frame shape and disposed between the glass substrates; a partition; an evacuation port; and a plurality of air passages. The partition partitions an internal space into an evacuation space, a ventilation space, and a coupling space. The evacuation port connects the ventilation space to an external environment. The plurality of air passages includes: a first air passage connecting the evacuation space to the coupling space; and a second air passage connecting the coupling space to the ventilation space. The second air passage includes a particular air passage having a larger dimension than any of the first air passage.

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.

Abstract: A glass panel unit includes a first panel, a second panel, a sealing portion in a frame shape, a plurality of pillars, and a gas adsorbent. The sealing portion in the frame shape hermetically bonds respective peripheral edges of the first panel and the second panel together so as to create an evacuated, hermetically sealed space between the first panel and the second panel. The plurality of pillars and the gas adsorbent are arranged in the hermetically sealed space. The gas adsorbent contains: a non-metallic getter material having a porous structure with the ability to adsorb gas molecules; and a metallic getter material having a metallic surface with the ability to adsorb gas molecules.
