Publication number: 20210087744Abstract: A dyeing method in which a transparent resin body having a surface applied with a dye is heated to fix the dye to the transparent resin body comprises a heating step of irradiating a laser beam having a wavelength less likely to be absorbed by the dye toward the transparent resin body applied with the dye on the surface while relatively scanning the laser beam with respect to the transparent resin body to heat a to-be-dyed region of the transparent resin body to fix the dye, wherein the laser beam is irradiation to heat by changing a laser beam irradiating condition with respect to a portion of the transparent resin body to be heated so that a heating temperature on the transparent resin body by irradiation of the laser beam is substantially equal throughout an entire area of the to-be-dyed region.Type: ApplicationFiled: December 3, 2020Publication date: March 25, 2021Applicants: NIDEK CO., LTD., SHIZUOKA PREFECTURAL GOVERNMENTInventors: Minoru INUZUKA, Hiroyasu UETA, Hiroyasu ATSUMI

Patent number: 9534344Abstract: Disclosed is a dyeing method using a laser beam. The method can dye transparent resins such as plastic lens well. Also disclosed is a dyeing apparatus. The dyeing method comprises heating a plastic lens having a dye-coated surface to fix the dye on the surface of the plastic lens. The method comprises the step of applying a laser beam with a wavelength, which is less likely to be absorbed in the dye but it absorbed in the plastic lens, onto the surface of the plastic lens through the dye.Type: GrantFiled: March 23, 2009Date of Patent: January 3, 2017Assignees: NIDEK CO., LTD., SHIZUOKA PREFECTURAL GOVERNMENTInventors: Minoru Inuzuka, Hiroyasu Ueta

Patent number: 7189418Abstract: The present invention provides a method for extracting a lipid mixture having a high percentage of phospholipids comprising polyunsaturated fatty acids. The method comprises the steps of (a) heating the viscera of fish with hot water or steam; and (b) extracting from the heated viscera of fish, using a solvent, the lipid mixture containing phospholipids comprising polyunsaturated fatty acids. The lipid mixture obtained by the present method contains phosphatidylserine comprising docosahexaenoic acid and phosphatidylethanolamine comprising docosahexaenoic acid in high concentration.Type: GrantFiled: February 12, 2003Date of Patent: March 13, 2007Assignees: Kabushikikaisha Maruhachi Muramatsu, Shizuoka Prefectural GovernmentInventors: Seiichi Hiratsuka, Toshihiro Suzuki, Masayuki Hashidume, Youko Matsue, Tomoko Kitagawa, Masaaki Yokoyama, Masami Tamura, Tatsuya Fujii, Noriyuki Muramatsu

Patent number: 4883196Abstract: A packaging box is used for packaging frozen food with an improved heat-insulating property. The movement of air surrounded by a corrugated core of a conventional corrugated card-board is interrupted, thereby enhancing the heat-insulating property. The air is prevented from permeating through the corrugated property. Further in order to improve the heat-insulating property, laminated aluminum foil is used.Type: GrantFiled: September 12, 1988Date of Patent: November 28, 1989Assignees: Shizuoka Prefectural Government, Nihon Dimple Carton Co., Ltd.Inventors: Eiji Kato, Katsumi Kuboshima, Tomoyuki Kaneko
