Patent number: 5372903Abstract: Respective phosphor layers (3R), (3G) and (3B) and a light absorption layer (2) are formed on the inner surface of a panel. An intermediate layer (11) is selectively formed on the surfaces of the respective phosphor layers by using a water soluble liquid having photosensitivity and containing water dispersion vinyl polymer emulsion and partial saponification polyvinyl acetate-system photosensitizer and then a metal-backing layer (12) is formed. A color purity of a phosphor screen can be increased and a brightness thereof can be improved.Type: GrantFiled: February 3, 1993Date of Patent: December 13, 1994Assignees: Sony Corporation, Oji Kako, Co., Ltd.Inventors: Norihiro Tateyama, Katsutoshi Ohno, Tsuneo Kusunoki, Hiroshi Itoh, Shuichi Nakazato, Naoki Isobe

Patent number: 5360860Abstract: A water-soluble resin emulsion comprising at least two incompatible water-soluble polymers, wherein said incompatible water-soluble polymers are stably compatibilized with each other by emulsion-polymerizing a monomer having a reactive unsaturated group in the presence of said incompatible water-soluble polymers as the protecting colloid. The emulsion is useful for a topcoating, prime-coating, material for a synthetic leather, photosensitive material for the preparation of a color filter, material for silver salt photography, and photosensitive material for screen printing.Type: GrantFiled: June 26, 1992Date of Patent: November 1, 1994Assignee: Oji Kako Co., Ltd.Inventors: Hiroshi Itoh, Naoki Isobe, Tadashi Asazuma

Patent number: 5268286Abstract: A biocatalyst is immobilized with a graft product of a polymer and saponified polyvinyl acetate containing a stilbazolium group as a photo-crosslinking group. The polymer is preferably gelatin, collagen, starch, cellulose, gum arabic, tragacanth gum, carrageenan, mannan, dextrin or alginic acid. The graft product is prepared by bonding the polymer to the polyvinyl acetate, either directly through functional groups of the polymer and polyvinyl acetate or through a crosslinking agent. The polymer provides affinity for the biocatalyst and by grafting the polymer to the saponified polyvinyl acetate, damage to cells upon immobilization is reduced. A liquid composition containing a biocatalyst and the graft product is added to an aqueous solution of an inorganic salt or an organic salt to form a granular gel and the gel is irradiated with actinic rays to cure the gel.Type: GrantFiled: March 6, 1991Date of Patent: December 7, 1993Assignees: Ojo Kako Co., Ltd., Kansai Paint Co., Ltd.Inventors: Takeshi Kobayashi, Shinji Iijima, Masamichi Kamihira, Mikiko Hata, Takamitsu Iida, Masahiro Sakamoto, Hiroshi Itoh, Naoki Isobe

Patent number: 4799310Abstract: A method of manufacturing a bar antenna having a magnetic core incorporated therein includes removing a covering material from each end portion of parallel covered cords, the parallel covered cords being separated from each other by a length required for winding on the magnetic core, the portions wherefrom the covering material is removed being connected together. A winding start position is set beforehand so that an end portion of the magnetic core can be matched in position with the winding end of a coil. One cord, a connecting portion and the other cord are wound in sequence consecutively from the start position to the end portion of the magnetic core, starting from the base of the separated portions of the cords, so as to form the coil, and thereafter the coil thus formed is transferred to a prescribed position, while the portions of the parallel covered cords not separated from each other are used as an extension cord as they are.Type: GrantFiled: December 30, 1986Date of Patent: January 24, 1989Inventors: Atsushi Isobe, Masahiko Isobe, Naoki Isobe
