    摘要: An improved traveling magnetic field-type apparatus for crushing, mixing, polishing, deburring and the like is provided, comprising a container containing working substances and a quantity of material to be crushed operatively arranged between first and second traveling magnetic field generators. The generators are selectively shiftable between a first orientation and a second orientation, in which like polarity and dissimilar polarities face each other across the container. The field generators may be circular and concentrically arranged, or in the shape of a circular arc. Diaphragms also may be provided in the container to distribute more uniformly the working substances and the material to be crushed. It has been determined that the working substances are more readily magnetized, resulting in a higher magnetic torque, if they are relatively longer in the axial direction than in the cross sectional direction. Weighted portions may also be provided at each axial end of the pieces of the working substance to further concentrate the mass at each axial end, and thereby further increase the torque.

    摘要: A porous membrane of vinylidene fluoride resin, having two major surfaces, including a dense layer which governs filtration performance on one major surface side and a sparse layer which contributes to reinforcement on the other opposite major surface side, and having an asymmetrical gradient network texture including pore sizes which increase continuously from the one major surface to the other opposite major surface, wherein the dense layer includes a 7 μm-thick portion contiguous to the one major surface showing a porosity A1 of at least 50%, and the one major surface shows a pore size of at most 0.30 μm. The vinylidene-fluoride-resin porous membrane is useful as a porous membrane for separation and particularly exhibits good water-permeation-rate retentivity even in continuous filtration of cloudy water.
