Abstract: A glass panel unit manufacturing method includes a punching step and a pillar mounting step. In the punching step, a punch punches at least one of a plurality of portions from a base material of a sheet to form at least one pillar. Each of the plurality of portions is surrounded by a corresponding one of a plurality of loop-shaped grooves in the base material. In the pillar mounting step, the at least one pillar is mounted on a surface of a first substrate including a glass pane.

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: 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; subsequently dividing the space by a region forming member disposed inside the space to form a partial region which do not include the outlet; and subsequently cutting out the partial regions by cutting the pair of glass panels.

Abstract: An object of the disclosure is to provide a glass panel and a glass window which are configured to stably maintain a depressurized space therein even when their spacers contain a resin. A glass panel unit of an aspect of the disclosure includes: a first glass pane; a second glass pane facing the first glass pane; a frame member which has a frame shape and which the first and second glass panes are bound together through; and spacers containing a resin and disposed between the first and second glass panes. A depressurized space is provided between the first glass pane and the second glass pane. The first and second glass panes are respectively to be exterior and interior panes. The first glass pane has lower ultraviolet transmittance than the second glass pane.

Abstract: The panel unit includes a first panel, a second panel facing the first panel with a space provided therebetween the first panel and the second panel, a partition separating the space from a surrounding space, and a switching mechanism. The switching mechanism is located in the space for allowing a change in thermal conductivity between the first panel and the second panel. The switching mechanism includes at least one connector which is thermally conductive, and is switchable between a first state in which the at least one connector is out of contact with the first panel or the second panel and a second state in which the at least one connector is in contact with both the first panel and the second panel.

Abstract: The glass panel unit includes a first glass panel, a second glass panel, a seal, an evacuated space, and at least one spacer. The second glass panel is placed opposite the first glass panel. The seal with a frame shape hermetically bonds the first glass panel and the second glass panel to each other. The evacuated space is enclosed by the first glass panel, the second glass panel, and the seal. The at least one spacer is placed between the first glass panel and the second glass panel. The at least one spacer has a height H1 smaller than a height H2 of the seal between the first glass panel and the second glass panel.

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.
