  • Publication number: 20230266655
    Abstract: A reflective screen including a lens layer having a Fresnel lens shape with a plurality of unit lenses and a reflective layer formed on the unit lenses to reflect light. The unit lenses protrude from a video source side to a back surface side in the thickness direction of the lens layer, the lens layer has a flat edge section where a portion of the back surface side serves as a flat surface, and h1min-h2 > 0 is satisfied, where h1min is the minimum height distance in the thickness direction of the lens layer from a position of the lens layer most on the video source side to a position of the unit lenses most on the back surface side, and h2 is the height which is the distance from the flat surface of the flat section to the position of the unit lenses most on the back surface side.

  • Publication number: 20230130094
    Abstract: A reflective screen including a Fresnel lens-shaped lens layer having unit lenses and a reflective layer formed on the unit lenses for reflecting light. The unit lens protrudes from a video source side to a back surface side in the thickness direction of the lens layer. In the lens layer, a flat part having a flat surface f on the back surface side is formed at at least one end edge. In the thickness direction of the lens layer, a maximum lens height h1max of a lens height h1 that is the distance from a position closest to the video source side to a position closest to the back surface side, and a flat surface height h2 that is the distance from the position closest to the video source side of the unit lens to the flat surface f of the flat part 114 satisfy h2?h1max.

  • Patent number: 9746588
    Abstract: Disclosed is a method for manufacturing a visibility improvement sheet that comprises light absorbing portions having a substantially rectangular cross-section and can realize a high contrast while maintaining a view angle. The visibility improvement sheet is manufactured by forming light transparent portions juxtaposed to each other at predetermined intervals to form grooves having a substantially rectangular cross section juxtaposed to each other between the light transparent portions, filling the grooves with an ink composition comprising a transparent ionizing radiation curable resin composition and colored fine particles, and curing the ink composition in such a state that fine air bubbles are randomly dispersed in the filled ink composition.

  • Publication number: 20130252133
    Abstract: A membrane-catalyst layer assembly with reinforcing films including a solid polymer electrolyte membrane 2, a catalyst layer 3 formed on each surface of the electrolyte membrane 2, and a reinforcing film 4 located on each surface of a membrane-catalyst layer assembly having the electrolyte membrane and the catalyst layers. Each of the reinforcing films 4 has a frame shape with a central opening 41. Each of the catalyst layers 3, except for an outer edge portion 31, is exposed through the opening 41. Each reinforcing film 4 has a first bonding layer 43 bonded to a membrane-catalyst layer assembly 10, and a gas barrier layer 42 formed on the first bonding layer 43 to prevent passage of a fuel gas and an oxidant gas.

  • Patent number: 8518597
    Abstract: The present invention provides a catalytic layer-electrolytic membrane laminate for an unhumidified-type fuel cell, comprising an electrolytic membrane containing a strong acid; a conductive layer formed on one surface or both surfaces of the electrolytic membrane; and a catalytic layer formed on the conductive layer; wherein the conductive layer is formed of a fluorine-containing resin and carbon powder, and the conductive layer is thinner than the electrolytic membrane. The present invention provides a catalytic layer-electrolytic membrane laminate for an unhumidified-type fuel cell that can be practically used.

  • Patent number: 7485393
    Abstract: The present invention relates to a laminate for battery encasement comprising aluminum foil and an inner layer, wherein a resin film layer that comprises an aminated phenol polymer (A), an acrylic polymer (B), a phosphorus compound (C), and a zirconium compound (D) lies between the aluminum foil and the inner layer. The laminate for battery encasement of the present invention is excellent in adhesiveness, gas impermeability, etc., and therefore can be suitably used as a material for encasing a secondary battery, particularly a lithium ion polymer secondary battery.
