摘要： A photocurable prepreg sheet for waterproofing includes (1) a fiber-reinforced resin layer which comprises a sheet-shaped inorganic or organic fibrous reinforcing material impregnated with a resin composition comprising: (A) an unsaturated polyester resin and/or vinyl ester resin: 100 parts by weight, and (B) at least two photopolymerization initiators having photosensitivity in different wavelength ranges from ultraviolet range to near infrared range: 0.01 to 10 parts by weight, and which is treated with light of a specific wavelength to thereby undergo prepolymerization which causes at least one of the polymerization initiators and radical-polymerizable unsaturated groups to remain partially intact; and (2) film which covers an upper surface and a back surface of the fiber-reinforced resin layer. The waterproofing material does not require resin impregnation work, can be installed within a short time with successful resin setting, is free form the risk and cumbersome procedure which are caused when a peroxide catalyst is directly handled, and permits adjustment of the pot life. Also disclosed are method and apparatus for production of the prepreg sheet, and waterproofing method using the sheet.

摘要： An optical disc device of the present invention comprises an insertion detection optical sensor which detects insertion of an optical disc based on light emitted from a first light emitting element to a first light receiving element being blocked, and an ejection detection optical sensor provided on the downstream side in the carry-in direction to the insertion detection optical sensor to detect ejection of the optical disc based on light emitted from a second light emitting element to a second light receiving element being blocked. The optical disc device is structured such that, in a state that the optical disc is attached onto the turntable, when the light of the first light emitting element is blocked and the light of the second light emitting element is not blocked, the optical disc device recognizes that a lens cleaner is attached onto the turntable as the optical disc, and the optical disc device performs a cleaning operation.
