  • Publication number: 20200306801
    Abstract: A method for regenerating an adhesive surface by removing a foreign matter adhering to the adhesive surface of a component holding jig. The method includes: disposing, on the adhesive surface, a mask member having: a surface which is in contact with the adhesive surface and has an arithmetic mean roughness of 1.0 ?m or less; and an opening through which the adhesive surface is exposed; disposing a curable resin composition on the adhesive surface and on the mask member and curing the curable resin composition; and simultaneously peeling off the mask member and a cured product of the curable resin composition.

  • Patent number: 10772213
    Abstract: An adhesive substrate is disclosed, which includes a base substrate and a heat-resistant elastomer layer formed on the base substrate, wherein the base substrate is flexible and has a thickness of 0.2 mm or more and 2 mm or less, wherein the adhesive substrate is used as part of a method for physically separating an object that has been held immovable in such a manner that the object has been adhered to by the heat-resistant elastomer layer and the object is anchored from the upper side, and wherein by starting to physically separate the end portion of the adhesive substrate downward the object is able to be separated.

  • Patent number: 4307320
    Abstract: Pigment coated phosphors comprising a europium activated yttrium oxysulfide phosphor having a europium activator value within a range of 0.04 gram atom to 0.066 gram atom per 1 mol of yttrium oxysulfide having adhered thereto red colored pigment particles such as cadmium sulfoselenide pigment particles, rouge pigment particles or red lead pigment particles, in respective amounts of 0.1 to 2.0 wt %, 0.05 to 2.0 wt % or 0.1 to 12 wt %, based upon the europium activated yttrium oxysulfide phosphor; and a cathode ray tube for high contrast color television using as a red emitting phosphor at least one of the three pigment coated phosphors.

  • Patent number: 4152483
    Abstract: On the surface of a phosphor, pigment particles are uniformly adhered by a layer of a gelatin-gum arabic mixture. A process for manufacturing such a pigment coated phosphor includes the steps of preparing an aqueous solution of gelatin and an aqueous solution of gum arabic, allowing the phosphor to disperse homogeneously into one of these aqueous solutions, allowing the pigment particles to disperse homogeneously into the other aqueous solution, and mixing the so obtained phosphor and pigment dispersions.
