Title: Reagent for quantitative measurement
Inventor: HAYASHI TOSHIHIRO
IPC: G01N31/22
Filed: 1993-11-30
Abstract: PURPOSE:To obtain a reagent used for the quantitatively measuring compounds of aromatic peimary amines by mixing 2-aminoanthracene and its derivative or 2-aminonaphthalene and its derivative in the reagent. CONSTITUTION:When a reagent for quantitatively measuring compounds of peimary aromatic amines, the basicity of an object to be measured is reduced. Therefore, when, for example, sulfanilic acid which is one of sulfa drugs or p-aminobenzoic acid which is a representative compound of aromatic primary amines, hippuric acid, etc., is a compound to be tested, the compound is not extracted with an organic solvent when 1-aminonaphthalene derivative is used under an acidic condition or basis condition, but the compound can be extracted with the organic solvent under an acidic condition when this reagent is used. Since this reagent has a different position for coupling reaction from that in a conventional reagent, a reaction product can be extracted with the organic solvent. Therefore, this reagent can be applied to high performance liquid chromatography (HPLC) and the measurement sensitivity can be improved.

Title: Production of carbon material for sliding current collection
Inventor: FUJIMOTO KENICHIRO
IPC: C04B35/52
Filed: 1990-11-30
Abstract: PURPOSE:To obtain a highly strong carbon series sliding current collecting material having low electric resistant and high resistance to brittle fracture by a method wherein a carbonaceous powder material is added with specific quantity of metallic fibers and admixed and then it is molded or subjected to hydrostatic press and sintered followed by impregnation with a metal having melting point lower than that of the admixed metallic fibers. CONSTITUTION:Metallic fibers are admixed by 5vol.%-60vol.%, preferably, 10-45vol.%, for the total of carbonaceous powder material and the metallic fibers. When it is lower than 5vol.% electric resistance does not decrease sufficiently whereas when it is higher than 60vol.% the carbonaceous material is not sintered sufficiently thus causing drop of strength. Thus obtained mixture material is then molded or subjected to hydrostatic press and sintered at a temperature lower than the melting point of the metallic fiber under environment of inert gas such as argon or nitrogen thus carbonizing the mixture material. It is then subjected to metal impregnation. The impregnating metal must have melting point lower than that of the admixed metallic fiber.

Also, the diameter of the laser beam on the surface of the sample 4b becomes 3.58 times of the case in which the laser beam is made incident in vertical direction. As a result, the width of a single-crystal region when Si is used can be doubled approximately.
