  • Publication number: 20080305282
    Abstract: An antireflection film including a polyester base 10 and an antireflection layer that is disposed on a side 10a of one principal surface of the polyester base 10 by the wet coating method. The antireflection layer includes, from a side of the polyester base 10, a hard coat layer 11 and a low-refractive index layer 12 that is disposed above the hard coat layer. The hard coat layer is provided directly on the polyester base 10, the hard coat layer contains a metal oxide, and the metal oxide is contained in a ratio of 20 vol % to 42 vol %. The present invention provides an antireflection film in which a primer layer for improving adhesion is not provided between a polyester base and a hard coat layer and the occurrence of interference fringes is suppressed, and that delivers excellent antireflection performance and exhibits high scratch resistance, and a display front plate using the antireflection film.

  • Patent number: 7172817
    Abstract: An aqueous solution of a tin salt and an indium salt is added to an aqueous alkaline solution to form a hydroxide or a hydrate comprising tin and indium, the hydroxide or hydrate is heated at a temperature of 110 to 300° C. in the presence of water, filtered and dried, and then the hydroxide or hydrate is heated at a temperature of 200 to 1000° C. to form the tin-containing indium oxide particles. Thereby, tin-containing indium oxide particles which have a plate-form shape and an average particle size in the plane direction of 10 to 200 nm are obtained. The tin-containing indium oxide particles are suitable for forming an electrically conductive transparent coating film.

  • Publication number: 20070020470
    Abstract: The present invention provides an optical film including: a base; a first functional layer provided on one principal plane of the base via a first adhesion-improving layer; and a second functional layer that is different from the first functional layer and is provided on the other principal plane of the base via a second adhesion-improving layer. The first adhesion-improving layer contains a resin that is different from a resin contained in the second adhesion-improving layer, and the second functional layer contains a resin of the same type as the resin contained in the second adhesion-improving layer. The optical film according to the present invention achieves excellent adhesion between the respective functional layers and the base as well as excellent reflectance spectral characteristics.

  • Patent number: 5661090
    Abstract: Ceramic semiconductor packages which comprise a lead frame (1) having registering holes (4, 5) and a ceramic substrate (2) having a thermally fusible bonding material such as a resin or glass applied to the sealing surface (6) of the substrate are manufactured by positioning the lead frame, using a transfer device (14), on a lead frame-supporting plate (11) having holes (20, 21), through which positioning pins (22) formed on a positioning base (12) are made to protrude by lifting the base (12) by a driving mechanism (13), in such a manner that the positioning pins pass through the registering holes (4, 5) of the lead frame. The substrate is then centered and positioned on the lead frame using a transfer device (15) having chuck hands (33). Thereafter, the bonding material is fused by heating in a heating furnace (16) to bond the lead frame and the substrate.
