Abstract:
A method for manufacturing a dye-attached substrate to be used in a dying process for dyeing a resin body by heating a sublimable dye to cause the dye to sublimate toward the resin body includes an arranging step of arranging a to-be dyed substrate, to which the dye is to be adhered, that is formed in a roll shape, and of which a surface on the side to which the dye is to be adhered is formed on an outside surface of the roll-shaped to-be-dyed substrate, in a printing device, such that the outside surface of the roll-shaped to-be-dyed substrate faces an ink head of the printing device, when printing the dye on the to-be-dyed substrate using the printing device, and a printing step of printing the dye on the to-be-dyed substrate, by discharging ink that includes the dye to be deposited on the resin body, toward the to-be-dyed substrate using the ink head of the printing device.
Abstract:
A dyeing device dyes a resin body by vaporizing and depositing a sublimation dye adhered to a dyeing base to a resin body provided in an installing unit and fixing the dye to the resin body. The dyeing device lowers the pressure inside a closed chamber that closes the periphery of the resin body by a pump (S27). In the state where the adhesion surface of the dyeing base to which the dye is adhered faces the resin body without contact, by heating the dye adhered to the dyeing base inside the closed chamber of which the pressure is lowered, the dye is sublimated, vaporized, and deposited on the resin body (S28). The pressure inside the closed chamber is raised higher than the pressure at the vaporizing and depositing time (S30). By irradiating the resin body on which the dye is vaporized and deposited with electromagnetic wave, the resin body is heated and the dye is and fixed (S36).
Abstract:
A method for manufacturing an optical lens includes a preparation step (S1) in which coating solution application conditions for an optical lens substrate are satisfied, and a coating step (S2) in which a coating solution is applied to the lens surface of the optical lens substrate. The coating solution application conditions with reference to the convex surface side include a first condition and a second condition. The first condition is a condition that the angle of the axis of an optical lens substrate (1) with respect to the horizontal direction falls within a predetermined angle range. The second condition is a condition that the optical lens substrate rotates around the axis at a predetermined rotational speed. The predetermined angle range is an angle range between a maximum inclination angle of the axis at which the peripheral edge of a lens surface is positioned at the highest position of the lens surface, and a maximum inclination angle of the axis at which the peripheral edge of the lens surface is positioned at the lowest position of the lens surface. The predetermined rotational speed is a rotational speed at which the coating solution applied to the lens surface is held in a coating position.
Abstract:
Provided is a method for producing an optical lens in which a processed pattern can be accurately formed on a lens surface at a predetermined position of a lens substrate without limiting the material. A mark adapted to perform position alignment is formed outside a lens region set in a lens substrate (11). A masking layer (21) is pattern-formed above one principal surface of the lens substrate (11) by an inkjet method while formation position of the masking layer (21) is controlled with the mark as a reference, wherein the masking layer (21) has an aperture pattern (21a) at a predetermined position in the lens region. A selective process with respect to a surface exposed from the aperture pattern (21a) of the masking layer (21) is performed by performing a process from above the masking layer (21). The masking layer (21) is removed from above the lens substrate (11) to form a transparent pattern (19a), as the processed pattern, by the selective process on the side of the one principal surface of the lens substrate (11).
Abstract:
A coating device (42) for a coating solution and a light beam radiating device (151) which cures the coating solution are arranged in a clean room (7). Spectacle lenses (2) include a set of two lenses and are stored in a coating container (50). The coating device (42) applies the coating solution to coating target surfaces of the spectacle lenses (2) in the coating container (50). When the set of two spectacle lenses (2) coated with the coating solution are extracted from the coating container (50), they are stored in a lens rack (120) and sealed by a transparent plate of the light beam radiating device (151). After air in the lens rack (120) is purged with nitrogen gas, curing treatment for the coating solution is performed by the light beam radiating device (151).
