摘要： PURPOSE:To measure the sample characterized by quick reaction highly accurately by rotating a rotary table twice or more for one conveying measurement. CONSTITUTION:When a measurement starting signal is inputted from a control part 114, a sample 101, a first reaction reagent 104 and a diluent liquid 106 are added into a reaction container 101 at a position (a) through a sample distributing device 105 and a diluent-liquid distributing device 107. Thus the first distribution is performed. Then, the control part 114 rotates a rotary table 102 by one container. The first distribution is performed on the container 101 which is moved to the position (a). A second reaction reagent 108 is added into the container 101 which is moved to a position (b), and the second distribution is performed. Then, the control part 114 rotates the table 102 at least two or more rotations. The chemical change of the sample is measured by two or more times through optical detecting means 110 and 111. The conveying measurement such as this is performed. The distribution and the conveying measurement are alternately repeated by the same way, the measuring time interval can be shortened without the restriction on the distributing time and the measuring time interval can be adjusted by the rotating speed of the table.

摘要： PURPOSE:To obtain a film-forming material capable of imparting sufficiently high adhesive force even by the use in wet state, and free from the problems such as polymerization shrinkage, etc., by compounding a polymer having phosphorus-containing group with a specific metal alkoxide and optionally a chelating agent. CONSTITUTION:The objective material can be produced by compounding (A) the polymer having the phosphorus-containing group of formula I (Z1 and Z2 are O or S), preferably the group of formula II [Z3 is O, S or NR' (R' is H, alkyl or aryl); R is H, alkyl, aryl or group of formula III (R'' is R'); n is 0 or 1] with (B) the alkoxide of one or more metals selected from Ti, Zr, Al, Sn, Ca and Fe, and if necessary (C) a chelating agent such as a benzoic acid derivative, catechol, etc. The addition of the component C enables the long-term storage of the film-forming material. The amount of the component B is 0.02-1.0mol per 1mol of the phosphorus-containing group of the component A and that of the component C is 0.1-4mol per 1mol of the component B.

摘要： PURPOSE:The titled composition causing no reduction in mechanical strength, having low decay properties, obtained by blending powder prepared by mixing fluoride-containing aluminosilicate glass powder with a specific soluble polymer with a solution of a polymer of an unsaturated carboxylic acid. CONSTITUTION:A solution component comprising a polymer of copolymer of an unsaturated carboxylic acid such as methacrylic acid, maleic acid, etc. is blended with a powdery component obtained by covering aluminosilicate glass powder comprising silica and alumina as main components and a fluoride with a polymer (e.g., polyvinyl pyrrolidone, polyethylene glycol, polyethylene-imine, etc.) of an aprotic polar monomer containing nitrogen and/or oxygen, to give a dental cement composition. EFFECT:Having good workability in blending, capable of preventing second decay.
