    摘要: Provided is an electric motor driven by an inverter of PWM method, and devised to retard electrolytic corrosion in a bearing. A rotating body of a rotor comprises an outer iron core configuring an outer peripheral portion of the rotating body, an inner iron core configuring an inner peripheral portion connected to a shaft, a dielectric layer disposed between the outer iron core and the inner iron core, a plurality of insertion holes penetrating the outer iron core in the axial direction, and permanent magnets inserted individually in the plurality of insertion holes. It thus becomes possible to increase impedance of the rotor side (inner ring side of bearing) to approximate it to impedance of the stator side (outer ring side of the bearing) to thereby bring high frequency potentials balanced between the inner ring side and the outer ring side of the bearing, so as to provide the electric motor that retards electrolytic corrosion liable to occur in the bearing, and an electric device equipped with the same.

    摘要: A black resin composition capable of forming a black matrix having high OD value and high adhesion as well as high resistance is disclosed. The black resin composition is a black resin composition comprising at least a light shielding agent, a resin and a solvent, which light shielding agent contains at least titanium nitride compound particles, wherein the angle of diffraction 2θ of the peak originated from (200) plane of the titanium nitride compound particles when CuKα line is used as the X-ray source is not less than 42.5° and not more than 42.8°. Using this black resin composition allows a thin resin black matrix having a high light shielding property and high resistance to be readily attained.
