Abstract: PROBLEM TO BE SOLVED: To provide a pilfer-proof cap made of a metal which has no possibility of remaining a burr on a skirt part of the cap when it is unsealed and exhibits excellent safety, and to provide a method for manufacturing the cap. SOLUTION: In the pilfer-proof cap, the rolling direction of a base material in a broad bridge part 7a connecting a pilfer-proof band 5 is made to be 60-90° to the rotating direction of a cap body. In addition, in a method for manufacturing the cap, after a plate-like base material 21a rolled in a specified direction is press-processed to mold a cylindrical cap shell 1a with a top plate part 2, this cap shell 1a is positioned so that the rolling direction of a metal in the broad bridge part 7a becomes in the direction of 60-90° to the rotating direction of the cap body 1 to perform sewing a machine processing.

Abstract: PROBLEM TO BE SOLVED: To provide a new secondary optical system glass member homogenizer for condensing solar power generation of which the installation is simple and which can suppress the decrease in an optical efficiency and a power generating efficiency. SOLUTION: In the secondary optical system glass member homogenizer 10 for condensing solar power generation which uniformly radiates sunlight L condensed with a primary condensing member 51 to a power generation element 52, an upper or lower surfaces are constituted of a glass material 11 in a shape of a horizontal block, an inner peripheral surface 16 has a hollow section 15 formed in an inverted truncated pyramid shape or an inverted truncated cone shape, and a reflective film 20 for reflecting the sunlight L is formed in the inner peripheral surface 16 of the hollow section 15.
