摘要： A novel photoacid generator containing a structure of the following formula (I), wherein R is a monovalent organic group with a fluorine content of 50 wt % or less, a nitro group, a cyano group, or a hydrogen atom, and Z1 and Z2 are individually a fluorine atom or a linear or branched perfluoroalkyl group having 1-10 carbon atoms, is provided. When used in a chemically amplified radiation-sensitive resin composition, the photoacid generator exhibits high transparency, comparatively high combustibility, and no bioaccumulation, and produces an acid exhibiting high acidity, high boiling point, moderately short diffusion length in the resist coating, and low dependency to mask pattern density.

摘要： A welding apparatus for welding an end plug on the end of a pellet filled nuclear fuel rod includes a holding mechanism, an abutting member, a torch and a pressing mechanism. The holding mechanism is for holding the external periphery of the fuel rod with the end plug attached thereto. The abutting member is disposed opposite to the holding mechanism, and the end plug of the fuel rod butts up against the abutting member. The torch is disposed between the holding mechanism and the abutting member, and is placed diametrically opposite to the external surface of the fuel rod. The holding mechanism and the abutting member are made so that the distance therebetween can be adjusted, and the pressing mechanism is provided on one of the holding mechanism or the abutting member, and operates to move the holding mechanism and the abutting member to approach each other. In a welding apparatus of such a design, the fuel rod is held by the holding mechanism, and the pressing mechanism pushes the holding mechanism toward the abutting member, and while retaining such a position at a constant compressive force, welding of the end plug is performed. Therefore, the welding is performed without being affected by the variations in the compressive force caused by welding heat distortions, thereby providing a weld of high integrity and quality.
