Abstract: A manufacturing method of a glass panel unit of the present invention includes a bonding step, a pressure reduction step, and a sealing step. In the bonding step, a first substrate and a second substrate are hermetically bonded together with a seal having a frame shape. In the pressure reduction step, a pressure in an inside space formed between the first substrate and the second substrate is reduced through an exhaust port. In the sealing step, sealant disposed between the first substrate and the second substrate is deformed, and the sealant thus deformed seals an opening of the exhaust port.

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: In s glass panel unit, a pitch of pillars is determined such that a distortion of a first panel and second panel is smaller than an interval between the first panel and the second panel. The distortion is calculated based on the interval between the first panel and the second panel, load loading compression fracture per one pillar of the multiple pillars, Young's moduli of the first panel and the second panel, thicknesses of the first panel and the second panel, and Poisson's ratios of the first panel and the second panel.

Abstract: An object of the disclosure is to provide a manufacturing method of a glass panel unit which is simply performable. A manufacturing method of a glass panel unit of an aspect of the disclosure includes housing a preassembled component including a first glass panel, a second glass panel, and a frame member disposed between the first and second glass panels to hermetically bond the first glass panel to the second glass panel in a chamber and evacuating the chamber to achieve a reduced pressure state. The frame member has an exhaust port communicating with inside and outside spaces. The chamber has a thermally conductive pressing part movable to press the first and second glass panels in a direction in which the first and second glass panels approach each other. The manufacturing method includes heating the frame member by a heater to deform the frame member to close the exhaust port.

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.

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.

Abstract: The glass panel unit is a predetermined part separated from a completed assembly obtained by subjecting a temporary assembly to a predetermined process. In the temporary assembly, the inside space (500) enclosed by the first and second glass substrates and the frame is divided into the first space and the second space with the partition and the gas adsorbent is inside the first space. The predetermined process includes: converting the first space into the evacuated space by evacuating the first space through the gas passage, the second space, and the outlet; and changing a shape of the partition to close the gas passage to form the seal enclosing the evacuated space. The predetermined part includes: a first and second glass panels being parts of the first and second glass substrates; the seal; the evacuated space; and the gas adsorbent.

Abstract: A glass panel unit includes: a first glass pane; a second glass pane facing the first glass pane; a frame member; an evacuated space; and a gas adsorbent. The frame member hermetically bonds the first glass pane and the second glass pane. The evacuated space is surrounded with the first glass pane, the second glass pane, and the frame member. The gas adsorbent is placed in the evacuated space. The gas adsorbent contains a getter material. The getter material contains a plurality of particles of a zeolite crystal. At least one particle accounting for a half or more of a total weight of the plurality of particles has a particle size equal to or greater than 200 nm. An activable temperature of the at least one particle is equal to or lower than 400° C.

Abstract: A glass panel unit includes: a first panel including a glass pane; a second panel including another glass pane; a sealing portion; an exhaust port; and a printed portion. The second panel is arranged to face the first panel. The sealing portion is formed in a frame shape and hermetically bonds respective peripheral edge portions of the first and second panels to create an evacuated, hermetically sealed space between the first panel and the second panel. The exhaust port is provided for one panel selected from the first and second panels. A port sealing member hermetically seals the exhaust port. The printed portion is provided for the other panel selected from the first and second panels. The printed portion is located in an area, facing the exhaust port, of one surface of the other panel. The one surface either faces toward, or faces away from, the hermetically sealed space.
