    摘要: An aerial display apparatus includes: a display device which displays an image; a mirror device which includes a plurality of optical elements each including two reflective surfaces that are orthogonally disposed, which reflects display light from the display device, and which forms an aerial image at a position that is plane-symmetrical to the display device; and a light shielding member which is disposed on an optical path between the display device and the aerial image, which includes an opening that allows a portion of incident light to pass through, and which shields light incident on a region other than the opening.

    摘要: A steam-releasing pouch includes two laminated sheets forming an accommodation compartment that accommodates a content, a sealing portion that seals the two sheets to form an opening that opens part of the accommodation compartment, and a steam-releasing sealing portion formed in the sealing portion to open as pressure of the accommodation compartment increases in a state in which the opening is sealed. The steam-releasing sealing portion includes a first sealant layer having at least a first base layer that faces the accommodation compartment and a second base layer laminated with the first base layer and a second sealant layer having at least a third base layer that faces the accommodation compartment and a fourth base layer laminated with the third base layer. The first base layer and the third base layer are joined together.

    摘要: A fuel cell membrane electrode assembly and a polymer electrolyte fuel cell, which improve drainage in a high current range where a large amount of water is produced, without hindering water retention under low humidification conditions, and exhibit high power generation performance and durability even under high humidification conditions. A fuel cell membrane electrode assembly according to a first embodiment of the present invention includes a polyelectrolyte film, and two electrocatalyst layers sandwiching the polyelectrolyte film. At least one of the two electrocatalyst layers includes catalyst support particles with a hydrophobic coating, a polyelectrolyte, and a fibrous material having an average fiber diameter that is 10 nm or more and 300 nm or less. The fibrous material has a mass that is 0.2 times or more and 1.0 times or less the mass of the carrier in the catalyst support particles.
