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 method for manufacturing a pillar supply sheet is a method for manufacturing a pillar supply sheet including a plurality of pillars, a carrier sheet, and an adhesion layer between each of the pillars and the carrier sheet, the method including a pillar forming step. The pillar forming step is a step of forming the plurality of pillars by subjecting the base member to an etching process or a laser irradiation process and removing an unnecessary portion from the base member after the process.

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.

Abstract: The objective is to propose a production method of multiple panes which can be simple and nevertheless produce a multiple pane in its finished state which does not include any undesired protrusion from an external surface of a glass panel. The production method includes: hermetically bonding, with a sealing member, peripheries of paired glass panels disposed facing each other at a predetermined distance to form a space to be hermetically enclosed between the glass panels; evacuating air from the space through an outlet to make the space be in a reduced pressure state; and dividing, after the space is made be in the reduced pressure state, the space by a region forming member into an outlet region including the outlet and a reduced pressure region other than the outlet region.
