Abstract: A vacuum glass panel includes a first glass plate, a second glass plate facing the first glass plate, a frame member having a frame shape and bonding the first glass plate to the second glass plate, and a heat reflective film disposed on an inner surface of the first glass plate. A vacuum space is provided between the first glass plate and the second glass plate. The heat reflective film separates the first glass plate from the vacuum space without a gap. The frame member is in contact with the first glass plate.

Abstract: A first glass substrate, a die including a penetrating space, a seat member, and a punching member are set so as to be arranged in this order. Subsequently, the seat member is punched by the punching member to remove part from the seat member through the penetrating space of the die. The part removed, is placed on the first glass substrate by the punching member so as to allow the part to serve as at least one spacer. Thereafter, the second glass substrate is placed on the first glass substrate with the at least one spacer in-between to form a glass panel unit.

Abstract: The glass panel unit includes a first glass panel, a second glass panel, a seal, an evacuated space, and a 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 spacer is placed between the first glass panel and the second glass panel. The spacer contains polyimide represented by chemical formula (1):

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: A work in progress includes: a pair of glass substrates arranged to face each other; a peripheral wall having a frame shape and disposed between the pair of glass substrates; a boundary wall; and an evacuation port. The boundary wall hermetically separates an internal space, surrounded with the pair of glass substrates and the peripheral wall, into an evacuation space, a buffer space, and a ventilation space. The evacuation port connects the ventilation space to an external environment. The evacuation space and the buffer space have a lower internal pressure than the ventilation space. A predetermined part, including the evacuation space but excluding parts covering the buffer space and the ventilation space, of the work in progress, forms the glass panel unit.

Abstract: A method for manufacturing a glass panel unit includes an assembling step, a bonding step, a gas exhausting step, a sealing step, and an activating step. The bonding step includes melting a peripheral wall in a baking furnace at a first predetermined temperature to hermetically bond a first glass pane and a second glass pane together with the peripheral wall thus melted. The gas exhausting step includes exhausting a gas from an internal space through an exhaust port in the baking furnace to turn the internal space into a vacuum space. The sealing step includes locally heating to a temperature higher than a second predetermined temperature, and thereby melting, either a port sealing material or an exhaust pipe to seal the exhaust port and thereby obtain a work in progress. The activating step includes activating a gas adsorbent after the sealing step to obtain a glass panel unit.

Abstract: An assembly includes: a pair of glass substrates; a peripheral wall disposed between the glass substrates; partitions; an evacuation port; and air passages. The partitions are provided to partition an internal space, surrounded with the glass substrates and the peripheral wall, into an evacuation space and a ventilation space. The evacuation port connects the ventilation space to an external environment. The air passages are used to evacuate the evacuation space through the evacuation port. The air passages include particular air passages arranged in a second direction perpendicular to a first direction, in which the glass substrates face each other, to constitute a ventilation path running through the internal space in the second direction.
