Moreover, two or more spaces partitioned by a partitioning plate are provided inside the container, at least one of the spaces is an agent dissolving chamber, at least one thereof is a cleaning water flow rate regulating-chamber, an opening part for connecting said chambers may be provided in a part of the partitioning plate, and a guiding plate for cleaning water may be provided in the cleaning water inlet.

Abstract: An object of the present invention is to provide a composition containing a biologically active substance, which has such an excellent moldability that it can give a favorable granular formulation even when it is not cut with a water-cooled cutter, and which can fulfill the performance required of a rumen-bypassing formulation and the like. The composition containing a biologically active substance of the present invention comprises 10 to 50% by mass of a protective substance comprising a linear or branched, saturated or unsaturated aliphatic C8-24 monocarboxylic acid (1a) having a melting point of lower than 50° C., a linear or branched, saturated or unsaturated aliphatic C8-24 monocarboxylic acid having a melting point of 50° C. or higher, and a calcium salt of a linear or branched, saturated or unsaturated aliphatic C12-24 monocarboxylic acid (2) having a calcium content of 8 to 12% by mass, and 50 to 90% by mass of a biologically active substance dispersed in the protective substance.

Abstract: An antifungal composition comprising 3-iodo-2-propynyl butylcarbamate, 4,5-dichloro-2-octyl-isothiazolin-3-one and methyl 2-benzimidazolylcarbamate is useful as industrial antifungal composition, particularly for wood protection.

Abstract: Application of an alkaline earth metal salt selected from calcium and strontium salts can steadily denature the allergens those exist in the environment without any coloring trouble on the treated material.

Abstract: There is disclosed a tongue depressor which has a light function to visually examine or clean the inside of a mouth easily and effectively, and which can be operated even by one hand, and light deep teeth or a throat part without any reductions in the amount of a light. Because of a structure in which a hole is bored in the main body of the tongue depressor, and a lighting fixture such as a commercially available penlight can be inserted/pulled out, two functions, i.e., a tongue depressor and lighting, can be provided. A shape is simple, fabrication costs are low, and sanitary supervision is easy. Since the tongue depressor can be operated by one hand, mouth cleaning can be carried out by the other hand.

Abstract: A polymer emulsion with good film forming property, which is mixed a synthetic polymer emulsion containing the polymer having the particle size of 0.15 &mgr;m or longer in diameter and a synthetic polymer emulsion containing the polymer having particle size of 0.10 &mgr;m or shorter in diameter, wherein the glass transition temperature of the latter polymer is at least 20 degree lower than that of the former emulsion and the particle size ratio between the former polymer and the latter polymer is 2 or more. The polymer emulsion is used for making moisture-proof coated paper and/or recyclable-coated paper.

Abstract: The present invention provides use of a composition containing 2-n-octyl-4-isothiazolin-3-one and N-n-butyl-1,2-benzisothiazolin-3-one for providing antifungal efficacy to a wood preservative containing copper oxide or a copper salt and a fungicidal azole. It also provides a wood preservative which comprises 2-n-octyl-4-isothiazolin-3-one, N-n-butyl-1,2-benzisothiazolin-3-one, copper oxide or a copper salt, and a fungicidal azole as active ingredients.

Abstract: A method for denaturing allergens with an effective amount of a rare earth metal salt.

Abstract: A method of producing a fine particle dispersion characterized by having a dispersing step where, after fine particles have been sucked into a dispersing medium to prepare a suspension by a suction type stirring machine and bubbles have been removed from the suspension by a bubble removing means, the suspension is pressurized and introduced from the opposite directions so as to collide with each other, thereby dispersing the suspension.

Abstract: The present invention provides a high pressure pump (1), which comprises an electric motor (2) having a through-hole in axial direction on a rotation shaft (5), a thrust transmission shaft (8) engaged with threads of a rotation nut (6) operated by rotation of the motor, passing through the through-hole and performing linear reciprocal movement, plungers (9a, 9b) performing reciprocal movement in cylinders and connected to at least one end of the thrust transmission shaft (8), and a stress-strain sensor (16) provided on at least one of the plunger or the thrust transmission shaft.
