    Abstract: A semiconductor device configures a protection element that protects a protection target element connected between a cathode electrode and an anode electrode when a parasitic transistor configured by a cathode region, a first conductivity type well layer, and a second conductivity type well is turned on and electrical continuity is established between the cathode electrode and the anode electrode. The semiconductor device includes a plurality of body regions in one cell of the protection element, and the plurality of body regions is brought in contact with the cathode electrode.

    Abstract: A control apparatus controls the operation of a starter such that, after an idling stop is executed and before a request for starting an engine is subsequently issued, the control apparatus executes a preset which causes a pinion to engage a ring gear. A control apparatus controls the operation of a starter such that, after an idling stop is executed and before a request for starting an engine is subsequently issued, the control apparatus executes a preset which causes a pinion to engage a ring gear. It is determined that the preset condition has been cancelled, and the preset is again executed. In that case, the pinion is already engaged with the ring gear at the time point when a request for starting the engine is issued. In that way it is unnecessary for the control apparatus to push out the pinion after a start request is issued.
