  • Patent number: 10627258
    Abstract: In a related-art resolver, a front and a back of a stator core cannot be distinguished, and it is difficult to mass-produce the resolver while matching directions of shear drops and burrs. Thus, assembly accuracy of the resolver is degraded. Further, productivity and assembling ability are degraded because electromagnetic steel sheets are laminated by rotary lamination. The present invention provides a resolver including: a resolver stator including: a stator core formed of electromagnetic steel sheets, which have teeth, and are laminated without rotary lamination; a one-phase excitation winding; and two-phase output windings; and a resolver rotor arranged to be opposed to the resolver stator, in which the stator core has marks which enable distinction of a rolling direction of the stator core and distinction of a front and a back of the stator core.

  • Patent number: 10192811
    Abstract: When a power semiconductor device is energized, heat generated from upper-side power semiconductor chips mounted on a P-potential electrode transfers to a first heat mass portion and a second heat mass portion, and heat generated from lower-side power semiconductor chips mounted on a intermediate potential electrode transfers to a resistor. A lead frame, the power semiconductor chip, an inner lead and the resistor are placed in symmetry with respect to a centerline, which can reduce the difference among the temperature increases of the power semiconductor chips when energized. In this way, transient temperature increase of the power semiconductor chip can be suppressed without adding a new member, such as a heat diffusion plate.
