  • Publication number: 20240059832
    Abstract: Provided is a transparent conducting film laminate suitable for three-dimensional molding having a curved surface. A transparent conducting film laminate comprising: a transparent substrate made of a transparent thermoplastic resin film, a transparent conducting film formed on at least one main face of the transparent substrate, and containing a binder resin and a metal nanowire, and a protection film formed on the transparent conducting film, and containing a resin component, wherein the binder resin contains at least on kind of poly-N-vinylacetamide, a copolymer containing 70 mol % or more of N-vinylacetamide (NVA) as a monomer unit, and a cellulose-based resin, and 94% by mass or more of the resin component constituting the protection film is derived from a thermoplastic resin.

  • Patent number: 11802535
    Abstract: Power can be efficiently generated in accordance with the amount of water in a channel by including: a first headrace channel positioned on an upstream side; a second headrace channel positioned on a downstream side; a water wheel on a most downstream side of the first headrace channel and the second headrace channel, the water wheel having a rotation shaft in a direction orthogonally intersecting with a water flow; a lateral movement apparatus that enables the second headrace channel to be moved in an upstream direction or a downstream direction; and a vertical movement apparatus that enables the water wheel to be moved in a vertical direction.
