  • Thin-film laminate type conductor
    Patent number: 6215077
    Abstract: A thin-film laminate type conductor is provided which includes a first conductor that is a metal thin film formed of Al or Al alloy, and a second conductor that is a transparent conductive thin film formed of a metal oxide. The first and second conductors are formed in respective patterns on a transparent substrate, such that at least a part of the second conductor is laminated on at least a part of the first conductor. The transparent conductive thin film is composed of an amorphous film. In another embodiment, the first conductor is composed of laminated metal thin films one of which is formed of Al or Al alloy, and the other of which is formed of a high-melting-point metal. The Al or Al-alloy film is sandwiched between the substrate and the high-melting-point metal film.

  • Organic light-emitting device and method of manufacturing the same
    Patent number: 6133581
    Abstract: An organic light-emitting device is formed of a transparent substrate, anodes in a stripe pattern formed on the transparent substrate, an organic film layer formed on the anodes, and cathodes formed on the organic film layer. Each of the anode includes a first conductor formed of a transparent and electrically conductive film containing a metal oxide as a main component, and a second conductor extending along the first conductor. The second conductor is formed of metal with a resistivity of 1/10 or less than a resistivity of a constituent material of the first conductor. Thus, the organic light-emitting device emits light efficiently with a low power consumption.

  • Multi-layer film
    Patent number: 4574104
    Abstract: The present invention relates to a multi-layer film comprising at least three layers of two outer layers and an intermediate layer sandwiched therebetween wherein the intermediate layer is formed of a resin composition of a high density polyethylene and an ethylene .alpha.-olefin copolymer, and the outer layers are formed of an ethylene .alpha.-olefin copolymer and at least one of the outer layers is formed of a resin composition of an ethylene .alpha.-olefin copolymer and a low density polyethylene.The object of the present invention is to provide a multi-layer film having a high mechanical strength and superior in properties such as heat sealability, anti-blocking, and suitability for automatic packaging.
