  • Radio wave absorber composition
    Patent number: 6797744
    Abstract: There is disclosed a composition which is layered in a reflective board to constitute a radio wave absorber. In this composition, an electroconductive titanium oxide is compounded with a substrate. With regard to the substrate, there may be used thermoplastic resin, thermosetting resin, rubber or elastomer.
    Type: Grant
    Filed: January 28, 2002
    Date of Patent: September 28, 2004

    Inventors: Osamu Hashimoto, Tetsu Soh, Masato Tadokoro
  • Electric-wave absorber
    Patent number: 6683246
    Abstract: The radio wave absorber of the present invention has a radio wave reflector and at least two radio wave absorbing layers disposed on a surface of the radio wave reflector, the at least two radio wave absorbing layers being formed of a base material and electroconductive titanium oxide mixed with the base material. The radio wave absorbing layers have different blend ratios of the electroconductive titanium oxide so as to make their radio wave absorption property different.
