摘要： In a magnetic recording medium wherein a magnetic coating composition comprising a binder and a magnetic powder is applied to the surface of a substrate, the dispersion of magnetic powder in binder is improved for enhanced physical and electromagnetic properties by using a vinyl chloride/hydroxyl group-containing vinyl monomer/polar group-containing monomer copolymer or a vinyl chloride/vinyl acetate/hydroxyl group-containing vinyl monomer/polar group-containing monomer copolymer having not been subjected to saponification, the polar group-containing monomer preferably containing an epoxy group as an additional polar group. Electromagnetic properties are further improved with a metal magnetic powder having a BET value of up to 60 m.sup.2 /g and a pH value of at least 7.

摘要： An exhaust-gas purifying apparatus includes an outer cylinder, a plurality of cylinder-shaped supports, and a catalytic layer. The cylinder-shaped supports are disposed in the outer cylinder, and have an outer peripheral surface and an inner peripheral surface. At least two of the neighboring cylinder-shaped supports contact with each other with the outer peripheral surfaces. The catalytic layer is loaded on at least one of the outer peripheral surface and inner peripheral surface of the cylinder-shaped supports. At least one of the cylinder-shaped supports has a ring-shaped cross-section with a cut-off, and is disposed in the outer cylinder in such an elastically deformed state that it expands in the centrifugal direction. Thus, the exhaust-gas purifying apparatus not only shows a high exhaust-gas purifying ability, but also is good in terms of the assemblage easiness. Moreover, the exhaust-gas purifying apparatus exhibits improved misfire resistance.
