Abstract: An assembly includes a plurality of partitions to partition an internal space, surrounded with a pair of glass substrates arranged to face each other and a the peripheral wall having a frame shape and provided between the pair of glass substrates, into an evacuation space and a ventilation space. The plurality of partitions includes a first partition and a second partition, of which lengths are defined in two different directions. An end of the second partition faces a side portion of the first partition with a predetermined gap left between them. A space between the end of the second partition and the side portion of the first partition constitutes an air passage to evacuate the evacuation space through an evacuation port. The second partition includes, at the end thereof, a swollen portion protruding toward the evacuation space at least along the width of the second partition.

Abstract: A glass panel unit assembly includes: a pair of glass substrates arranged to face each other; a peripheral wall; a partition; an air passage; and an evacuation port. The peripheral wall has a frame shape and is disposed between the pair of glass substrates. The partition partitions an internal space, surrounded with the pair of glass substrates and the peripheral wall, into a first space and a second space. The air passage connects the first space and the second space together. The evacuation port connects the second space to an external environment. The partition is lower in height than the peripheral wall.

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 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 irradiating a second sealant, inserted into the exhaust port, with an infrared ray through a region, where a low emissivity film is nonexistent, of the second substrate.

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.

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 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.
