Abstract: To provide an ultraviolet light irradiation device capable of inactivating bacteria, viruses, and the like with increased efficiency while ensuring safety. An ultraviolet light irradiation device according to the present invention includes a light source to emit ultraviolet light having a wavelength within a range of 190 nm or more and less than 240 nm, a housing to house the light source, a light extraction part to extract the ultraviolet light emitted from the light source out of the housing, and a diffusion transmission member to diffuse and transmit the ultraviolet light.

Abstract: A fastener stringer has a fastener tape provided with a tape main body portion and an element attaching portion and a plurality of fastener elements fixed by weaving to the element attaching portion of the fastener tape at the same time of weaving of the fastener tape, and is provided with a weaving structure with one pitch per one-rotation. A weft yarn of the fastener tape has a fineness larger than that of at least a part of a warp yarns disposed in the tape main body portion. Thereby, the productivity of the fastener stringer can be increased to reduce the cost. Further, the density of the weft yarn in the fastener tape can be increased, and the fastener tape can be less likely to be misaligned.

Abstract: In a woven fastener stringer, a weft thread is folded back while interlacing with a upper direction converting portion configured by an upper fixing warp thread and a lower direction converting portion configured by a lower fixing warp thread on a side close to engaging head portions of fastener elements. An upper extension portion configured by the upper fixing warp thread is placed in adjacent to a tape main body side of the upper direction converting portion. A lower extension portion configured by the lower fixing warp thread is placed in adjacent to the tape main body side of the lower direction converting portion. According to this, when a slide fastener is used in an inside out manner, it is possible to make it difficult to see the coupled fastener elements.

Abstract: An amidine-carboxylic acid complex in accordance with an aspect of the invention has an amidine ligand and a carboxylic acid ligand that are coordinated to one metal atom or a plurality of metal atoms of the same element. A multiple-complex-containing compound, i.e. a bridged polynuclear complex, in accordance with the aspect of the invention is formally derived from two or more such amidine-carboxylic acid complexes, linked by a polyvalent carboxylic acid ligand. The bridged polynuclear complex may be used in a production method to support metal (oxide) clusters on a porous support by impregnating these with a solution thereof, followed by drying and firing.

Abstract: A woven slide fastener in which displacements of element anchoring warps in a width direction of a fastener tape does not occur, flexibility of the fastener and smooth operation of a slider are ensured, and anchoring of a fastener element row is stable. Two anchoring warps disposed closest to coupling heads out of a plurality of element anchoring warps running over upper leg portions of the fastener element row run with and parallel to a double-picked foundation weft running under lower leg portions of adjacent elements and are woven in a width direction of a fastener tape body portion while interlacing with other element anchoring warps and foundation warps. Therefore, the element row can be anchored firmly, and the two anchoring warps do not fall off the elements, and other element anchoring warps also do not fall off of the elements.
