    • A synchronous machine comprises a stator and a rotor that faces the stator and rotates on a shaft thereof in a circumferential direction. The rotor has magnetic salient poles that generate reluctance torque and magnet-originating magnetic poles that generate magnet torque by using permanent magnets embedded in the rotor. The machine comprises means for shifting a magnetically substantial central position of magnetic flux emanating from the permanent magnets in the circumferential direction, by an electrical angle π/2 plus a predetermined angle Δθ, from a reference position taken as a central position between paired magnetic salient poles composing each magnetic pole of the machine among the magnetic salient poles. Hence a maximum amplitude of a sum between a harmonic component of the magnet torque and the reluctance torque is changed from that obtained at the reference position without the shift.

    • An electro-optic device includes a substrate body (transparent substrate) of a second substrate. The substrate body is provided with a first groove opened to a space (inter-pixel area) between pixel electrodes adjacent to each other. A transparent film is formed on one side face of the substrate body and side faces of the first groove, a second groove deeper than the first groove narrower than the first groove is formed at an area overlapped with the first groove in plan view in the transparent film. For this reason, light which tends to be directed to the inter-pixel area is directed to the pixel electrodes using the side faces of the second groove as reflection faces.
