摘要:
An optical apparatus includes: a focusing lens that focuses light which is one of recording light being irradiated to an optical recording medium with reference light for recording a hologram and reference light being irradiated to an optical recording medium for reading out a hologram; and a focal position-shifting unit that refracts the light while moving in accordance with a moving speed of the optical recording medium, so as to shift a focal position of the light in the optical recording medium a distance in a thickness direction of the optical recording medium.
摘要:
An optical device for holographic recording or reading is provided and includes: a light emission unit that emits light to be irradiated on an optical recording medium, the light being recording or reading light; a first prism unit that moves in accordance with a moving speed of the optical recording medium and refracts the light to move the light irradiated on the optical recording medium over a distance in a moving direction of the optical recording medium so that the light is irradiated on substantially the same position on the optical recording medium for a period of time; and a second prism unit that moves in accordance with the moving speed of the first prism unit to compensate for an optical path length of the light.
摘要:
A resin material used for a member for an image forming apparatus includes a polymer formed by polymerization of at least one acrylic resin in which a content ratio (molar ratio) of hydroxyl groups of side chains each containing 10 or more carbon atoms to hydroxyl groups of side chains each containing less than 10 carbon atoms is less than 1/3; at least one polyol that contains plural hydroxyl groups in which all the hydroxyl groups are connected together through a chain containing 6 or more carbon atoms; and an isocyanate, with a polymerization ratio of about 0.1 or more and about 10 or less, the polymerization ratio being a ratio (B/A) of a total molar amount (B) of hydroxyl groups contained in all the polyols used for the polymerization to a total molar amount (A) of hydroxyl groups contained in all the acrylic resins used for the polymerization.

Provided is a transparent plate for a platen which is used in a document scanning apparatus, including a transparent supporting member, and a transparent protective layer that has a self-repairability and has a surface coefficient of kinetic friction with respect to copy paper of 0.7 or less on the transparent supporting member.
摘要:
A urethane resin laminate includes a substrate material having a contact angle of water in the surface of the substrate material being from 0 degree to 90 degrees, an inner urethane resin layer, and an outer urethane resin layer in this order. The inner urethane resin layer contains urethane resin that does not have a fluorine atom in a molecular structure, and has self-repairability. The outer urethane resin layer contains urethane resin containing a fluorine atom in a molecular structure, and has self-repairability.
