    摘要： An electric power steering apparatus for a vehicle comprises a steering shaft (12), an electric motor (5) operable to generate an auxiliary steering force having a magnitude corresponding to a value of electric current supplied thereto, a steering torque sensor (8) for detecting a steering torque applied to the steering shaft (12), a vehicle weight sensor (9) for detecting a vehicle weight, and a control device (10). The control device is constituted to increase and decrease the value of electric current to be supplied to the electric motor in accordance with not only the increase and decrease of the value detected by the steering torque sensor but also the increase and decrease of the value detected by the vehicle weight sensor.

    摘要： A magnetic sensor has a elongate sensor region formed by an elongate magneto-resistive element (2) and an overlapping elongate conductive element (3). The ends of the magneto-resistive element (2) and the conductive element (3) are connected to terminals (T1,T2,T3,T4,T5) which are arranged in an array (10) which is spaced in a predetermined direction from the elongate sensor region. The array (10) may be at one side or one end of the elongate sensor region, and the terminals (T1,T2,T3,T4,T5) may have a linear arrangement within the array. The two terminals (T1,T2) connected to the magneto-resistive element (2) are preferably adjacent, and preferably the terminals (T1,T3) connected to the ends of the magneto-resistive element (2) and the conductive element (3) closer to the array (10) are also adjacent. A common terminal (T5) may be provided. Two such sensors may form a sensor array which is particularly suitable for use in a position sensor in e.g. a torque sensor of a power steering system.

    摘要： The object of the present invention is to provide a small size precise insulating type current sensor system.
    A sensing portion is composed of a magnetoresistance element, a bias conductor, and a current conductor, all of which are arranged on an insulating substrate. resistance change of the magnetoresistance element is taken into an amplifier, and an output of the amplifier flows an bias current to the bias conductor. When a current flows in the current conductor, the current causes a magnetic field and the resistance of the magnetoresistance element must be changed, but because a feedback of the resistance change by the amplifier changes the bias current and controls the bias current for keeping the magnetic field of the magnetoresistance element at a constant. Accordingly, the insulating type current sensing with a wide range and preferable preciseness without affected with hysteresis of the magnetoresistance element and Barkhausen noise became possible.
