Abstract: A system converts a first input idea vector representing an idea into a first contracted vector. The system generates one or more second contracted vectors in a multivariate space to which the first contracted vector belongs, based on a value of a first predetermined component of the first contracted vector in the multivariate space. The system generates, respectively from the one or more second contracted vectors, one or more first output idea vectors representing a candidate idea to be proposed to a user. The multivariate space is configured to maintain a similarity between an input idea vector for generating a contracted vector and an output idea vector generated from the contracted vector and a similarity between the first predetermined component of the contracted vector and a first predetermined index value.

Abstract: The present invention provides a coating method including: a step of supplying a coating agent to a surface of a lens base material; a spreading step of spreading the coating agent supplied to the surface by rotation of the lens base material; a first removal step of removing at least a part of a liquid pool of the coating agent generated on a peripheral edge portion and/or a side surface portion of the lens base material by rotation of the lens base material after the spreading step; and a second removal step of removing the liquid pool remaining on the peripheral edge portion and/or the side surface portion of the lens base material by bringing an adsorption member into contact with at least the side surface of the lens base material after the first removal step.

Abstract: A method of producing a plastic lens having a cured coating layer, comprising the steps of: forming an uncured coating layer from a photocurable coating composition comprising at least a) a photochromic compound, b) a radically polymerizable monomer and c) a photopolymerization initiator on one surface of a plastic lens; and irradiating the plastic lens having the uncured coating layer with light from an LED having an emission peak wavelength of 350 nm or more to less than 450 nm from above the outer surface of the uncured coating layer to cure the uncured coating layer.

Abstract: A cured coating layer can be provided to plastic lenses having various shapes with high productivity without causing deformation by providing a plastic lens for light exposure having an uncured coating layer composed of a photocurable composition on one surface and hydrogel adhered to the other surface, curing the uncured coating layer by exposing the uncured coating layer to light, and removing the hydrogel.

Abstract: A photopolymerization device (20) has: a workpiece holding part (1) that holds a workpiece (W); and a photoirradiation device (6) that is arranged above the workpiece holding part (1) and that radiates light toward the workpiece (W). The photopolymerization device (20) is configured such that a reflecting plate (3) that has a reflecting surface that has a specular gloss at angles of 60° of 10-200 is arranged below the workpiece holding part (1) and such that light that arrives at the reflecting surface of the reflecting plate (3) is radiated toward the workpiece (W).

Abstract: A photopolymerization device includes a base to which a shaft insertion hole is formed; a workpiece retaining and rotating shaft section which passes through the shaft insertion hole; cover member which has an opening closable by the base and forms workpiece accomodation chamber, accomodating the workpiece, by contacting the base with a peripheral part of the opening; light irradiation device; and controller which controls relative movement of the base and the cover member. The controller controls formation of the workpiece accomodation chamber by contacting the base with the peripheral part and rotation of the workpiece in a first region of the workpiece accomodation chamber, subsequently, the workpiece placement in a second region by relative movement of the workpiece retaining and rotating shaft section to the base, and light irradiation toward the workpiece placed in the second region by the light irradiation device.
