摘要： A displacement transducer is comprised of an magnetoresistive element, or an elongated semiconductor member having the magnetoresistive effect. A pair of electrodes are affixed at both ends of this magnetoresistive element, and a third electrode at the center. While an electric current is made to flow therethrough from each of the pair of electrodes to the third electrode, an applied magnetic field is moved thereon toward either side of the third electrode to obtain an output voltage due to the magnetoresistive effect of the element. In another embodiment of the invention, wherein a plurality of metal boundaries are formed at intervals between a pair of electrodes at both ends of an magnetoresistive element, a leading end of an applied magnetic field is inclined to such a degree as to extend between at least two adjoining ones of the metal boundaries.

摘要： Disclosed herein is a detector of local magnetic field, in which metallic electrodes are connected to the both ends and central part of at least one semiconductor having a magneto resistive characteristic thereby to form at least one magneto resistive element having three terminals, said element being arranged on a plane, whereby presence of a local magnetic field in said element can be detected from a voltage appearing across each of the central electrodes of said elements and a predetermined reference point. In addition, a semiconductor displacement transducer is also disclosed, which serves to produce an output voltage having any of the polarity, positive or negative, corresponding to a magnetic field displacement, by displacing the magnetic field applied to a part of the magnetoc resistive element with three terminals.
