摘要： A magnetostriction-type torque sensor has a rotating shaft having magnetostrictive properties and first and second coils which each constitute three or more closed loops. For each coil, the closed loop is disposed in a concentric relationship (a concentric circle located on a plane perpendicular to the rotating shaft) with the rotating shaft. Further, the direction of magnetostrictive properties of the rotating shaft detected by the first coil is made different from the direction of magnetostrictive properties of the rotating shaft detected by the second coil.

摘要： A power controller for a vehicle can operate electrical load upon stopping of engine or turning OFF of a key switch, without lowering of remaining capacity of a main battery. The control system has a control portion controlling operation of a power generator and an electrical load mounted on an automotive vehicle. The control system also includes remaining capacity measuring means for measuring a remaining capacity of a battery. The control portion energizes a predetermined power load when an engine is stopped or a key switch is held OFF, and operation of the power load is stopped when a remaining capacity of the battery measured by the remaining capacity measuring means becomes smaller than a predetermined value.
