  • Apparatus for suspension polymerization
    Patent number: 6264357
    Abstract: A method of suspension polymerization of a monomeric composition to produce a polymer or a polymer composition is disclosed which method comprises the steps of retaining a disperse phase component composed of the monomeric composition and a continuous phase component composed of a medium in independent vessels, supplying the disperse phase component and the continuous phase component from their respective vessels into a disperser simultaneously and continuously through associated independent passageways, applying shear force in the disperser to form a dispersion having droplets of a desired size, subsequently introducing the dispersion into a polymerization vessel, and completing a polymerizating reaction to produce a polymer or a polymer composition.
    Type: Grant
    Filed: December 27, 1993
    Date of Patent: July 24, 2001
    Assignee: Tomoegawa Paper Co., Ltd.
    Inventors: Masafumi Kamiyama, Haruhiko Yano, Minoru Tsuchida, Eiji O'Shima

  • Photo-fixing heat-sensitive recording media with photosensitive diazonium salt, coupler, and organic boron salt
    Patent number: 4511642
    Abstract: Photo-fixing heat-sensitive recording media which comprise diazonium salts, couplers and/or basic materials, all of these components being insoluble or sparingly soluble in water. At least one of these components is present in the media in the form of a fine powder. The coupler may be a coupler which has a basic group therein and serves as both a coupler and a basic material.
