摘要： The present invention is directed to diadenosine tetraphosphate (AP4A) tetrasodium salt dodecahydrate crystals represented by the following structure: Compared with the conventional amorphous anhydride of AP4A tetrasodium salt, the AP4A tetrasodium salt dodecahydrate crystals of the present invention have a low hygroscopicity and very stable physical properties. During storage, they are scarcely affected by environmental humidity. Thus, the present crystals can be easily handled as a medicine or a starting material for preparing a medicine, which broadens their application range.

摘要： A method of enzymatic analysis utilizing color-development signal amplification system associated with enzymatic cycling of NAD-NADH interconversion in the presence of dehydrogenase and its substrate, wherein the dehydrogenase is selected from the group consisting of alcohol dehydrogenase derived from Zymomonas and amino acid dehydrogenase derived from thermophilic microorganisms is disclosed. The use of alcohol dehydrogenase derived from Zymomonas provides an extremely higher detection sensitivity than that in the conventional method. The use of amino acid dehydrogenase derived from thermophilic microorganisms improves reliability of the method for longer period of time than that in the conventional method.

摘要： A polyester resin laminated plate which has a smooth surface, has less anisotropy of mechanical properties, is inexpensive, has no restriction in size, thickness, etc., and has a good cutting workability is produced by a process including the steps of melt-extruding a composition including 100 parts by weight of a thermoplastic polyester resin compounded with from 5 to 40 parts by weight of a fibrous reinforcing material and from 5 to 50 parts by weight of a granular inorganic compound to form sheets, forcibly cooling the sheets to a temperature lower than the glass transition point of the polyester resin to provide plural sheets having a surface crystallinity of less than 10%, laminating these plural sheets, and hot-pressing them at a pressure of from 15 to 150 kg/cm and at a temperature of from 80 to 260 DEG C, with the rate of temperature increase of 3 DEG C/minute or more to reach the temperature.

摘要： A method of analyzing a solution eluted from a metal pickled and an apparatus for the same are provided. A reagent is added to the solution to analyze a temperature titration and a change of ionic dissociations of reaction products. A temperature and an electrical conductibilitY of the solution during the reaction are measured to obtain a differential temperature curve and an electrical conductibility curve. The pseudoequivalent points of the reactions of the respective dissolved substances are determined from the differential temperature curve and kinds of the substances are identified from peak values of measured values on the electrical conductibility curve.
