摘要： The goal is to provide a medical suture needle having, as the material, austenite stainless steel with a structure that is elongated in a fiber form while improving the hardness and flexural strength of the cutting portion. A medical suture needle is made of austenite stainless steel having a structure that is elongated in fiber form, and has a cutting portion and a body portion with a triangular cross-sectional shape that is continuous with said cutting portion. The cutting portion has cutting edges, at least one surface of which is formed by a pressed surface, and which are formed by the intersection of said pressed surface with two sharpened surfaces, and a cutting edge that is formed by the intersection of the two sharpened surfaces. The tip where the various cutting edges and converge is positioned in the center of the pressed surface. Moreover, the cutting edges formed by the intersection of the above pressed surface with the two sharpened surfaces are longer than the cutting edge that is formed by the intersection of the two sharpened surfaces.

摘要： An economic hydrogenation process is provided which significantly suppresses palladium catalyzer activity loss, for obtaining very high purity 1,4-CHDA through a simple operation. The process includes bringing the solution containing the hydrogenation reaction product of interest into contact with steam. The resultant products may include resins having excellent weather resistance or physical properties or high purity medical drugs. The process for preparing 1,4-cyclohexandicarboxylic acid is characterized by two consecutive steps. The first step includes the hydrogenation of a solution containing terephthalic acid in the presence of a palladium catalyzer in an acid resistant vessel or in a vessel layered with acid resistant material for preparing 1,4-cyclohexandicarboxylic acid. The second step includes contacting the solution containing 1,4-cyclohexandicarboxylic acid obtained in the first step with the steam, and extracting impurities moved to the steam.

摘要： There is disclosed a current-limiting arcing horn comprising a current-limiting unit and a ring horn. The current-limiting unit is composed of lower and upper electrodes, at least one nonlinear resistor element mounted between the electrodes, and an insulating member made of an insulation. The insulating member encloses the electrodes and the nonlinear resistor element. The insulating member has a certain length which is 1.5 to 3.0 times as long as the length of the nonlinear resistor element. The creepage distance of the surface of the insulating means is 1.5 to 3.0 times as long as the length of the insulating member. The grounding electrode of the current-limiting unit is fixed to the earthside base of an insulator that holds an insulated wire. The ring horn is mounted to the upper electrode. An air gap is formed between the ring horn and the insulated wire to permit a flashover by lightning surge across the gap.

摘要： [Problem] To provide a medical cutting tool with low impalement resistance. [Solution] The edged medical cutting tool comprising a knife, trocar or cutting suture needle has a sharp edge (1) for incising living tissue and a flat part (2) that configures the edge, and the color of the portion of the flat part (2a) along the edge (1) differs from the color of the rest of the flat part (2b). The difference in color results from a difference in the thickness of an oxide film. Another edged medical cutting tool is configured of austenite stainless steel and has a sharp edge (1) for incising living tissue and a flat part (2) that configures the edge. The chrome content of the portion of the flat part (2a) along the edge is higher than the chrome content of the rest of the flat part (2b).

摘要： To provide an economically advantageous process for manufacturing crystalline maltitol and crystalline mixture solid containing crystalline maltitol. The process of this invention uses the syrup having a maltose purity of 81 to 90% as the starting material. The syrup is hydrogenated under the existence of catalyst, and then subjected to a chromatographic separation by using cation-exchange resin, resulting in an aqueous solution of maltitol having a maltitol purity of 94 to 99.9%. The aqueous solution, is further crystallized in the presence of a seed crystal, subjected to a separation, cooled and kneaded so as to manufacture both crystalline maltitol and crystalline mixture solid containing crystalline maltitol at the same time.
