    摘要: A magnetic recording medium includes a substrate, an underlayer provided on the substrate, a Co alloy magnetic film formed through the underlayer, and a protective film for protecting the magnetic film, wherein the underlayer has a two-layer structure of an lower underlayer contacted with the substrate and an upper underlayer contacted with the Co alloy magnetic film, the upper underlayer is a Co—Crx—My alloy film having a hexagonal close-packed structure, where 25 atomic %≦x+y≦50 atomic %, 0.5 atomic %≦y, nonmagnetic element M is one selected from the group of elements B, Si, Ge, C, Al, P, Ti, V, Nb, Zr, Hf, Mn, Rh, Os, Ir, Re, Pd, Pt, Mo, Ta, W, Ag and Au. Thereby the medium can be increased in its coercive force and can be improved in its thermal stability characteristics.

    摘要: A laminated capacitor that can be made small in size, that can prevent flashover, has excellent dielectric strength performance and a large capacitance is disclosed. Each gap between internal electrodes in the same plane is set at 2.7 to 20 times a thickness (element thickness) of a dielectric layer positioned between first and second internal electrode groups which face each other and a distance between an edge of the external terminal and an edge of the floating internal electrode closest to the external terminal among floating internal electrodes of the internal electrode group of the outermost layer is set at 0.4 mm to 1.4 mm.

    摘要: With a view to reduce vibrations generated by a motor and improve resistance to heat, reliability and vibration isolation properties without increasing the cost or the number of manufacturing steps in a rotor for a permanent-magnet motor, a rotor core is formed of an outer peripheral portion by which the permanent magnet is fixed, and a central portion by which a shaft is fixed, a clearance is provided between the outer peripheral portion and the central portion, and the outer peripheral portion is connected to the central portion by means of a plurality of fastening members. Thus, a rotor having excellent vibration isolation properties can be obtained. Since the rotor core is formed of laminated iron plates on which the outer peripheral portion, the central portion and the fastening members are all formed as one piece, resistance to heat, reliability and the vibration isolation properties can be enhanced without increasing the cost or the number of manufacturing steps.
