摘要： A magnetic recording medium is coated, over its magnetic layer, with a thin film of a siloxane-linkage-containing polymer. The magnetic layer consists of a thin film formed by vacuum evaporation or sputtering or by dispersion of a ferromagnetic metal powder in a binder. The polymer having the siloxane linkage is prepared by polymerizing an organo-silicon compound which either inherently possesses the linkage or is capable of producing it. The polymerization is preferably effected by the plasma polymerization technique.

摘要： A magnetic recording medium is provided comprising a flexible substrate and a ferromagnetic metal thin film layer on the substrate primarily comprising cobalt. When coercive force is measured by changing the measuring direction in a plane defined by a longitudinal direction of the substrate and a direction normal to the major surface of the substrate, the following relationship is met:(Hc.sub.max -Hc.sub.min)/Hc(O).ltoreq.0.9where Hc.sub.max is the maximum of the coercive force, Hc.sub.min is the minimum of the coercive force, and Hc(O) is a coercive force in the longitudinal direction of the substrate. The medium has in average at least 10.sup.5 /a.sup.2 protrusions per square millimeter of the surface, the protrusions having a height of 30 to 300 .ANG., where a is the distance as expressed in .mu.m of a gap in a magnetic head across which the medium is passed for recording and reproducing operation. The filling ratio of the ferromagnetic metal thin film layer is at least 0.7.

摘要： A transformer apparatus whose transformer and a plurality of circuit-breakers are individually accommodated in a plurality of different casings. The casings are stacked one above each other in a plurality of stages with gaps between two subsequent casings and between the casing in the lowermost stage and the floor surface on which the apparatus is mounted. When a specific casing among the plurality of casings which is in an intermediate stage is to be dismounted, support columns are disposed on the outside of the specific casing with their respective ends inserted into the relevant gaps in such a manner that the support columns support the upper subsequent casing, thereby enabling the intermediate casing to be dismounted and remounted.
