  • Patent number: 8414964
    Abstract: An electrically conductive film has an electrically conductive layer on at least one side, which is a thermoplastic resin film in which the electrically conductive layer contains a carbon nanotube (A), a carbon nanotube dispersant (B) and a binder resin (C), the total of contents of (A), (B) and (C) in the electrically conductive layer is 90% by weight or more relative to the entire electrically conductive layer, and weight rates of (A), (B) and (C) satisfy the following, and a weight ratio of (B) and (A) ((B)/(A)) is 0.5 or more and 15.0 or less: (A) 1.0 to 40.0% by weight, (B) 0.5 to 90.0% by weight, and (C) 4.0 to 98.5% by weight (provided that the total of contents of (A), (B) and (C) is let to be 100% by weight).

  • Publication number: 20130011613
    Abstract: A laminated film includes a resin layer provided on at least one surface of a thermoplastic resin film substrate, wherein the resin layer comprises an acrylic-modified polyester whose acrylic resin component has a glass-transition temperature of not lower than 67° C. and a sugar alcohol and/or a sugar alcohol derivative; the mass ratio of the acrylic-modified polyester to the sugar alcohol and the sugar alcohol derivative (the mass of the acrylic-modified polyester/the total mass of the sugar alcohol and the sugar alcohol derivative) is from 75/25 to 97/3; the total content of the acrylic-modified polyester and the sugar alcohol and sugar alcohol derivative is 65% by mass or more based on the total resin layer; and the haze value of the laminated film is not more than 2.0%.

  • Publication number: 20050223555
    Abstract: A method for forming small holes in a workpiece with a press tool (punch) and a female mold (die) of a press machine. The workpiece is positioned on the female mold such that the workpiece is positioned in the horizontal direction. The workpiece is then restrained only in the horizontal direction and is not pressed in the thickness direction of the workpiece. Since the holes are formed while the workpiece is supported without being pressed, reduction in the pitch accuracy due to the relief of the material, generation of burrs in regions around the holes, deformation such as sags, sticking of the material to the punch, etc., are avoided, and high-aspect-ratio, high-pitch-accuracy small holes are formed.
