Abstract: In a manufacturing method for manufacturing a dispersion body, a plurality of types of solid particles, water, and a liquid other than water are mixed. The solid particles and the liquid are selected such that Hansen spheres of at least two types of the solid particles and a Hansen sphere of at least one type of the liquid mutually overlap, and a Hansen solubility parameter distance to water of at least one type of the solid particles of which the Hansen spheres overlap that of the liquid is greatest among all solid particles used in manufacturing of the dispersion body, and used to manufacture the dispersion body.

Abstract: A honeycomb structure body is comprised of a honeycomb body, a pair of electrodes, a pair of electrode terminals and one or more slit sections. The honeycomb body is comprised of a cell formation section and an outer skin section. The outer skin section has a cylindrical shape and covers the cell formation section. The electrodes are formed on an outer peripheral surface of the outer skin section so that the electrodes face with to each other in a radial direction of the honeycomb structure body. Each electrode terminal is formed in an electrode terminal formation section on the corresponding electrode. One or more the slit sections are formed in at least one of an electrode terminal formation section and a circumferential outside section of the electrode terminal formation section.

Abstract: An exhaust gas filter purifies exhaust gas containing particulate matter emitted from an engine. The filter has cell walls and cells surrounded by the cell walls. Through pores formed in the cell walls, adjacent cells are communicated. The cells have open cells opening along an axial direction of the filter, and plugged cells. An upstream end part of the plugged cell is plugged by a plug member. On a cross section perpendicular to the axial direction, a flow-passage sectional area of the plugged cells is larger than a flow-passage sectional area of the open cells. A total length of the filter is not less than a first standard value and is not more than a critical length Lm determined by respective predetermined equations.

Abstract: An exhaust gas purification filter comprises: a casing; a porous dividing wall which partitions the inside of the casing into a honeycomb shape; and cells enclosed by the dividing wall. A pore path length distribution of the dividing wall, when expressed by a frequency histogram per 10 μm of the pore path length of the dividing wall, has an integrated frequency of at least 58%. The integrated frequency is a maximum value of a value obtained by summing the frequencies of a total of three adjacent levels which include the maximum peak frequency. The dividing wall preferably has a gas permeability coefficient k of at least 0.8×10−12 m2.

Abstract: An exhaust gas filter for purifying exhaust gases including particulate matter discharged from an internal combustion engine includes a honeycomb structure whose axial direction matches an exhaust gas flow, a plug portion which selectively plugs upstream end faces of the honeycomb structure which faces the exhaust gas flow, and catalyst carried on the honeycomb structure.The honeycomb structure has a plurality of partition walls and cells surrounded by the partition walls, and pores formed inside partition walls between adjacent cells communicating with each other. The plurality of the cells have open cells which are penetrated in the axial direction and plugged cells having one upstream end which face the exhaust gas flow plugged by the plug portion. The honeycomb structure has a first region which does not carry the catalyst on the partition walls and a second region which carries the catalyst on the partition walls.

Abstract: An exhaust gas purification filter collects PM contained in and purifies exhaust gas emitted from a gasoline direct injection engine. The exhaust gas purification filter has a honeycomb structural body which has a plurality of cells, partition walls and plug members. Each of the cells is surrounded by the partition walls. An opening section of one end of each of the cells is plugged by a plug member. The plug members satisfies a relationship of L/D≤50 and L≤3, where L is an average length (mm) of the plug members and D is an average pore size mm of the plug members. The honeycomb structural body and the plug members are made of cordierite. The cordierite contains silica, talc, kaolin, alumina and/or aluminum hydroxide, etc.
