  • Ion conductive polymers and imide monomers
    Patent number: 7592375
    Abstract: Disclosed herein is an ion conductive polymer comprising a unit represented by Formula (1) below: —SO2[N?SO2(M+)]X1-??(1) wherein X1 is an integer greater than 1, and M+ is H+ or Li+. Further disclosed is an imide monomer represented by Formula (A) below: Z1-SO2[N?SO2M+]Y-Z2 ??(A) wherein Y is an integer of 2 or greater, Z1 is OH, F, Cl, Br, I or NZ3Z4 (in which Z3 and Z4 are each independently H, M or SiMe3, and M is a metal element), Z2 is OH, F, Cl, Br, I or NZ3Z4 (in which Z3 and Z4 are each independently H, M or SiMe3, and M is a metal element), and M+ is H+ or Li+.

  • Dilation/erosion conversion circuit
    Patent number: 4980923
    Abstract: A circuit for processing a dilation conversion and erosion conversion of a digital image data to extract the feature of the image. A range N.times.N of the image data is processed by a simple circuit construction which a horizontal row extraction circuit holding N data and a conversion stage for converting N data are disposed in a crisscross arrangement.
