Abstract: An optical device according to one embodiment includes: a light-emitting element; first and second lenses optically coupled with the light-emitting element; an optical component provided between the light-emitting element and the second lens, optically coupling each of the light-emitting element and the second lens, and multiplexing input lights; and a base having a lower plate having a plurality of convex mounting surfaces with each of the light-emitting element, the first lens, the second lens, and the optical component being mounted thereon and a side wall with a receptacle being connected thereto.

Abstract: A composition for lowering a blood uric acid level is characterized by comprising taurine as an active ingredient.

Abstract: A tablet which comprises solid particles, especially magnesium oxide particles as the main component and has excellent shape retentivity with extremely low susceptibility to wearing and chipping. The tablet has a domed shape on each of the upper and lower horizontal surfaces of a cylindrical plate shape, wherein the domed shape on each of the upper and lower horizontal surfaces satisfies the following requirements (a), (b) and (c) in the cross-sectional shape including the center line of the cylindrical plate shape: (a) each corner has an angle of 25 to 45°, (b) each corner has a horizontal length of 0.30 to 1.0 mm, and (c) the cup has a depth of 0.6 to 1.2 mm.

Abstract: A blasting cartridge includes a generally cylindrical blasting container, a blasting substance filled in the blasting container, a pair of leadwires contained in the blasting container, and a single thin metal wire connected to tip portions of the pair of leadwires. The leadwires and the thin metal wire are positioned within the blasting substance within the blasting container. The blasting substance is nitromethane, and the thin metal wire is formed of tungsten. With an electric discharge impact blasting apparatus, since the thin metal wire has a higher heating value than a copper wire because of its higher resistance and vaporizes at higher temperatures, it is possible to obtain a greater blasting force at lower voltages than with a blasting apparatus using a copper wire.
