    Abstract: A connecting structure for medical use includes a male assembly (1) and a female connector (2) having a cylindrical configuration. The male assembly (1) includes a male connector (10) having a cylindrical configuration and a threadedly engageable cylinder (20) rotatably coupled to the male connector (10). A male luer portion (11) of the male connector (10) and a female luer portion (2a) of the female connector (2) are joined by turning the threadedly engageable cylinder (20) in a tightening direction when a female screw (21a) of the threadedly engageable cylinder (20) and an engageable protrusion (2c) of the female connector (2) are threadedly engaged with each other. The connecting structure for medical use further includes a loosening prevention mechanism (30) that prohibits rotation of the threadedly engageable cylinder (20) in a loosening direction with respect to the male connector (10) when the male luer portion (11) and the female luer portion (2a) are joined.

  • Publication number: 20130316127
    Abstract: A bamboo board of the present invention is produced by preparing a plurality of square tubular bodies fabricated by cutting a surface layer of tubes that form bamboo rods so that the cross sectional surfaces that are orthogonal to the longitudinal direction of the bamboo rods have two groups of two parallel facing surfaces, aligning the plurality of square tubular bodies parallel to one another, and gluing facing cut surfaces of the plurality of square tubular bodies in place by means of a first adhesive agent. The bamboo board is produced as a tube without splitting bamboo rods or cutting and shaping an arc-shaped bamboo material into a planar shape in a conventional method is a light-weight board having a sufficient strength, due to less deformation such as warping when using bamboo shaped into a planar configuration and use of a natural hollow structure of bamboo.

  • Patent number: 8268427
    Abstract: A display sheet includes a substrate; front-side and rear-side synthetic resin composition layers formed on front and rear surfaces, respectively, of the substrate; and an ink layer formed by ink-jet on the front-side synthetic resin composition layer. The substrate is made of sailcloth having projections and depressions on front and rear surfaces thereof. A surface of the front-side synthetic resin composition layer is formed on an irregular surface having projections and depressions attributed to the projections and depressions of the surface of the substrate. The ink layer is formed by causing a fine ink to cover the projections and permeate the depressions.

  • Patent number: 5769998
    Abstract: A workpiece comprising an aggregation body of platelike articles, sheet-like whose fibers have been opened by rolling, stick-like articles formed by finely tearing them from a single plate, flake-like articles, strand-like articles or the like is inserted between an upper heat plate 12 and a lower heat plate 13 of a heating press apparatus 10. A spacer 14 for surrounding the workpiece and determining the final thickness of the product is arranged on one or both of the heat plates before or after the insertion of the workpiece 11. The workpiece is compressed by the upper heat plate 12 and the lower heat plate 13 to thereby form an air tight compartment made of the upper heat plate 12, the lower the plate 13 and the spacer 14, and containing the workpiece. The air tight compartment is decompressed by vacuum for a predetermined period, then steam or heated gas is jetted onto the workpiece in the compressed air tight compartment.

  • Patent number: 5456964
    Abstract: A laminated material comprises a plurality of straight portions of vegetable stalks, each having an epidermis mainly of lignocellulose and a porous core. These vegetable stalks straight portions are impregnated with a thermal hardener solution of high-molecularizable liquid compound, resinified liquid, or mixtures thereof, arranged in parallel to form a layer of a sheet-like material, piling these sheet-like materials and pressing them to make these layers come to contact closely in flat condition. It is possible to make the directions of vegetable stalks in the sheet-like material different from the neighboring layers in order to strengthen a bending strength and other physical strength of the piled multi-layer laminated material, such as a pillar-like laminated material. Such pillar-like material is made by using a pair of pressing female mold and male mold, vegetable stalks being placed in the female mold and hot-pressed.
