  • Active energy ray curable resin composition, resin molded article, and method for producing resin molded article
    Patent number: 10040945
    Abstract: An active energy ray curable resin composition comprising: urethane poly(meth)acrylate (A) synthesized from a raw material including a polyisocyanate and a hydroxy group-containing (meth)acrylate; (meth)acrylate (B) having five or more functional groups; a photopolymerization initiator (C1) having an absorption coefficient per unit weight of 50000 ml/g·cm or more when measured in methanol at 254 nm; a photopolymerization initiator (C2) other than the (C1) having an absorption coefficient per unit weight of 50000 ml/g·cm or more when measured in methanol at 302 nm; a photopolymerization initiator (C3) other than the (C1) and the (C2) having an absorption coefficient per unit weight of 100 ml/g·cm or more when measured in methanol at 405 nm; and an ultraviolet absorbing agent (D).

  • Ceramic multilayer helical antenna for portable radio or microwave communication apparatus
    Patent number: 6046707
    Abstract: A small and durable antenna for use with radio and microwave communications is formed as a helical conductor contained in a multilayered non-ferrite ceramic chip. The dielectric constant of the ceramic is selected to match the antenna to its operating frequency, which may be in the range of 0.5 to 10.0 Gigahertz. A process for making such antennas is also disclosed. The antenna may be used in portable terminals and other devices requiring small, durable and inexpensive antennae.
