Abstract: The present invention relates to a gelled fluoride resin fine particle dispersion for use as a coating, to a method of production thereof, and to a method using this gelled fluoride resin fine dispersion to protect an alkaline inorganic hardened body.The objective of the present invention is to provide an aqueous resin for use as a coating, this aqueous resin being able to form a high performance coating film that is superior in its ability to inhibit the leaching out of the alkaline substance from the alkaline inorganic hardened body, which has excellent weatherability, water resistance, alkaline resistance, and dirt picking resistance.The present invention accomplishes the stated objective through the utilization of gelled fine particles of a fluorine containing resin.The present invention may be used in the coating field.

Abstract: Breaker units (3, 4) of three-phases are enclosed in a common container (25). The three-phase breaker units and lead conductors (27a, 28a) connected to both ends of the breaker units are arranged on imaginary straight lines that are in parallel each other nearly passing through vertexes of an equilateral triangle. A common operation unit (7) for driving the three-phase breaker units is accommodated outside the container (25) and juxtaposed at a position opposed to one side (28b-28c) of the equilateral triangle. A zero-phase sequence current transformer (ZCT) is provided surrounding the lead conductors of three phases outside the container.

Abstract: A cement dispersing agent comprising as an essential component a copolymer obtained by copolymerizing (a) 40 to 90% by weight, calculated as an alpha,beta-ethylenically unsaturated carboxylic acid, of the alpha,beta-ethylenically unsaturated carboxylic acid and/or its salt and (b) 60 to 10% by weight of an acrylic ester and/or a methacrylic ester of an alkyl alcohol having 1 to 4 carbon atoms, or a copolymer obtained by copolymerizing (a) 40 to 89% by weight, calculated as an alpha,beta-ethylenically unsaturated carboxylic acid, of the alpha,beta-ethylenically unsaturated carboxylic acid and/or its salt, (b) 51 to 10% by weight of an acrylic ester and/or a methacrylic ester of an alkyl alcohol having 1 to 4 carbon atoms and (c) 1 to 9% by weight of the other copolymerizable unsaturated monomer.
