摘要： A reluctance-type motor include a stator having a plurality of salient stator-poles, a rotor having a plurality of salient rotor-poles, a multi-phase coils mounted in the stator, and a driver circuit for driving said multi-phase coil. The driver circuit starts to supply drive current to the multi-phase coils when the salient rotor-poles and the salient stator-poles come across each other. In other words, the drive current is supplied to the multi-phase coils when the inductance thereof is zero.

摘要： In a spark plug voltage probe device, an electrically shield casing (301) is provided in which electrical circuit boards (302) are accommodated, the shield casing (301) having an electrically conductive wall (313) connected to the ground. An insulator base (303) is securely attached to an outer bottom of the electrical shield casing (301) and has an electrode plate (332) embedded in the insulator base to be connected to the electrical circuit boards (302). A rubber plate (342) is securely attached to a lower surface of the insulator base (303). A plurality of grooves (333, 341) are provided between the insulator base (303) and the rubber plate (342) to locate the corresponding cables (305) in the grooves (333,341) so as to form a static capacity (C1) between the electrode plate (332) and the cables (305). This makes it possible to reduce a noise level by the ratio of the static capacity (C1) to a static capacity (C2) between the electrically conductive wall (313) and the electrode plate (332). An electrical shield sheet (343) is fixedly attached to the lower surface of the rubber plate (342).
