摘要： Herein disclosed is a four-way valve for switching the cooling and heating modes of an air conditioner. The four-way valve includes: a first valve body of a cup shape having its closed wall formed with an outlet port and two circuit ports. A second valve body is provided having its root fitted fixedly on the first valve body and an inlet port formed at the side opposite to the body root. A cylindrical valve member is fitted rotatably in the first valve body having its one half formed in its end portion with an arcuate groove for providing alternate communication between the outlet port and the circuit ports and its other half formed with two communication ports. A member is provided for restricting the rotations of the cylindrical valve member. A magnetic member is provided for magnetically rotating the valve member when energized. A collar is disposed on the valve member and made irrotational but movable in the axial direction. A retainer is disposed on the open end of the first valve body for retaining the valve member. An urging member urges the valve member toward the first valve body through the collar.

摘要： Disclosed is a magnetic recording medium which comprises a film of an aromatic polyamide having at least 50 mole % of recurring units represented by the following general formula: ##STR1## wherein m and n are integers of from 0 to 4, with the proviso that the case where both of m and n are 0 is excluded,and at least one high performance magnetic layer of a metal or metal compound vacuum-deposited on the aromatic polyamide film. This magnetic recording medium shows a reduced dimensional change and is substantially free of curling or breakage due to elongation, and is excellent in flatness and adhesive strength between the base film and the magnetic layer. Accordingly, this magnetic recording medium is suitable for high-density magnetic recording.
