  • Publication number: 20240174845
    Abstract: The present invention provides: a resin pellet composition excellent in terms of low-classification property, kneadability with liquid ingredients, and transportability; a method for producing the resin pellet composition; and a method for producing a microporous polyolefin film from the resin pellet composition. The resin pellet composition comprises first pellets, which comprise a polyolefin, and 0.1-99.0 mass % liquid component. The first pellets are porous objects, some of which contain some of the liquid component infiltrated thereinto. In another embodiment, the resin pellet composition includes second pellets, which include a polyolefin. The second pellets are non-porous objects each comprising a portion made of a resin comprising the polyolefin and a portion made of a liquid component. The mass of the liquid component present on the outer surfaces of the second pellets is 20 mass % or less with respect to the total mass of the second pellets.

  • Publication number: 20240159605
    Abstract: This pressure sensor is configured to detect pressure. The pressure sensor comprises a first sheet member and a second sheet member. The second sheet member is disposed so as to overlie the first sheet member. First and second electrodes are formed on the first sheet member. A third electrode which is covered by a pressure-sensitive electroconductive layer is formed on the second sheet member. When the pressure sensor is being used, a voltage is applied between the first and second electrodes. Regardless of whether the pressure sensor is being used, the first and second electrodes are each in contact with the pressure-sensitive electroconductive layer.

  • Patent number: 10323453
    Abstract: A multiple-glazed glass unit of the present invention is adapted to separate an indoor space and an outdoor space and includes a pair of glass panes opposed across a gap layer to be spaced at a predetermined distance from each other. Low-emissivity (Low-E) films are formed on both principal surfaces of one of the pair of glass panes that is located closer to the indoor space. The low-emissivity film formed on one of the two principal surfaces that faces the indoor space has an arithmetic average surface roughness Ra of 14 nm or less. This multiple-glazed glass unit is configurable to have a higher SHGC value ever than before as well as keeping a low U-value.
