  • Patent number: 8778116
    Abstract: A method for producing a carbon nanotube-containing conductor having a conductive layer on the surface of an objective substrate, the method including: pressing a carbon nanotube network layer, via a release substrate having the carbon nanotube network layer thereon, against a transparent objective substrate coated with an electron beam-curable liquid resin composition to infiltrate the liquid resin composition into the carbon nanotube network layer; irradiating it with electron beams to cure the liquid resin composition; and peeling away the release substrate to obtain an objective substrate having a resin composition layer with carbon nanotubes embedded in the surface thereof.
    Type: Grant
    Filed: December 2, 2008
    Date of Patent: July 15, 2014
    Assignee: Meijyo Nano Carbon Co., Ltd.
    Inventors: Yoshiyuki Morimoto, Nobuo Kubosaki, Noriyuki Nakamura, Yuzo Sumita
  • Publication number: 20100252184
    Abstract: The invention is to provide a method for producing an inexpensive carbon nanotube-containing conductor having high transparency and high conductivity as well as excellent durability. The invention is a method for producing a carbon nanotube-containing conductor having a conductive layer on the surface of an objective substrate, and the method includes the steps of pressing a release substrate having a carbon nanotube network layer, via the carbon nanotube network layer thereon, against a transparent objective substrate coated with an electron beam-curable liquid resin composition to infiltrate the liquid resin composition into the carbon nanotube network layer; irradiating it with electron beams to cure the liquid resin composition; and peeling away the release substrate to obtain an objective substrate having a resin composition layer with carbon nanotubes embedded in the surface thereof.

  • Patent number: 3945552
    Abstract: A method and apparatus for forming a corrugated waveguide which has pairs of sub-blocks for forming the corrugated metal tube into the desired shape repeatedly by mating the sub-blocks, separating and advancing them intermittently so that the desired elliptic section or predetermined shape of section of the corrugated tube may be gradually approximated.
