  • Patent number: 9884740
    Abstract: A fiber bundle which has a pieced part formed by jetting a pressurized fluid against a fiber-bundle overlap is formed either by directly superposing the ending part of a fiber bundle composed of many fibers on the beginning part of another fiber bundle composed of many fibers or by superposing the end part and the beginning part on a jointing fiber bundle composed of many fibers, whereby the many fibers of the fiber bundles are interlaced with one another to thereby piece up the fiber bundles. The pieced part comprises an opened-fiber part in which the fibers have been opened and interlaced-fiber parts respectively located on both sides thereof, each interlaced-fiber part being composed of a plurality of constituent interlaced parts located apart in the width direction for the fiber bundle.

  • Publication number: 20130142948
    Abstract: A photochromic lens manufacturing system has an orderer side computer (101) and a manufacturer side computer (201) connected with each other through a communication line (300), and is adapted to manufacture a photochromic lens with an optical surface forming device (204), a photochromic film forming device (202) and a hard film forming device (204) under control of the manufacturer side computer (201). The orderer side computer (101) transmits lens substrate data related to a substrate material of the lens, optical surface data related to optical surfaces of the lens, data related to the photochromic film and data related to a hard film to the manufacturer side computer (201) through the communication line (300).

  • Publication number: 20120101617
    Abstract: An object of the present invention is to make it possible to manufacture a photochromic lens on made-to-order basis within short time, without keeping a stack of the photochromic lens. A photochromic lens manufacturing system has an orderer side computer (101) and a manufacturer side computer (201) connected with each other through a communication line (300), and is adapted to manufacture a photochromic lens under control of the manufacturer side computer (201). The orderer side computer (101) transmits lens substrate data related to a substrate material of the lens, optical surface data related to optical surfaces of the lens, data related to the photochromic film and data related to a hard film to the manufacturer side computer (201) through the communication line (300).

  • Publication number: 20100255193
    Abstract: A coating liquid manufacturing step for manufacturing a coating liquid for being coated on a lens substrate includes a step for filtering an original coating liquid with a filter having a fiber structure, the original coating liquid being prepared by mixing coating materials. The filter has an organic fiber layer (2) and an inorganic fiber layer (1). The original coating liquid is filtered with the organic fiber layer side as primary side.

  • Publication number: 20100239776
    Abstract: The present invention relates to a method of manufacturing a plastic lens comprising a cured film on at least one of a pair of opposing surfaces of a plastic lens substrate. The method of manufacturing a plastic lens of the present invention comprises heating the plastic lens substrate to a temperature greater than or equal to a glass transition temperature of the substrate; coating a photocurable composition on at least one of a pair of opposing surfaces of the lens substrate following the heating; forming a cured film by irradiating the photocurable composition that has been coated on the substrate with light to cure at least a portion of the composition; and conducting a heat treatment of the plastic lens on which the cured film has been formed at a temperature, the temperature being lower than the glass transition temperature of the substrate but greater than or equal to a glass transition temperature of the cured film.
