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: 9415463Abstract: This invention provides a laser marking method that can form a very minute mark of a predetermined shape, such as a letter or pattern, with clarity and high solidity, on the surface of a substrate. The laser marking method of the invention comprises the steps of (1) depositing a coloring material on the surface of a substrate of thermoplastic material to form a thin film of the coloring material, and (2) applying a laser beam to the thin film of the coloring material in conformity with a predetermined marking shape to cause the portions of the substrate irradiated with the laser beam to soften and to cause the thus softened portions to mix with the coloring material, thereby developing the predetermined marking shape on the surface of the substrate.Type: GrantFiled: January 26, 2010Date of Patent: August 16, 2016Assignees: Shizuoka Prefecture, Shikibo Ltd., Nidek Co., Ltd.Inventors: Hiroyasu Ueta, Minoru Inuzuka, Yutaka Tsujimoto
