摘要： An optical fiber bundle unit is provided for transmitting ultraviolet light in which the increase of the transmission loss caused by radicals generated in the optical fiber by irradiation or transmission of ultraviolet light is suppressed and a stable energy state is maintained even after the irradiation or transmission of ultraviolet light. The optical fiber bundle unit for transmitting ultraviolet light includes an optical fiber bundle and a sealed container in which the optical fiber bundle is held. A diffusion of hydrogen gas is suppressed by putting the optical fiber bundle pretreated in a hydrogen atmosphere into the sealed container, followed by filling the sealed container with a mixed gas including a hydrogen gas and a gas which is not combustible, will not support combustion, and will not explode.

摘要： A thermoplastic skin sheet constituted by (a) a thermoplastic polyolefin or elastomer sheet; (b) a primer layer coated on the sheet, the primer being based on a modified polyolefin resin containing 2 mg-equivalent/g or less of a hydroxyl group or a carboxyl group; and (c) a topcoat layer coated on the primer layer. The topcoat layer may be mainly composed of (a) 100 parts by weight of a polycarbonate polyurethane resin having a number-average molecular weight of 8,000 or more and a 100% modulus of 20 kg/cm2 or more, and (b) 0.1-40 parts by weight of a (meth)acrylate-butadiene-styrene resin. The surface of the topcoat layer may be subjected to embossing.
