摘要： A demagnetizer for removing residual magnetism in vehicles includes a single coil which is adapted to surround a portion or the whole of the body of a vehicle. A direct current and alternating current are supplied to the single coil simultaneously to produce a d.c. magnetic field and an a.c. magnetic field. The direction and magnitude of the d.c. magnetic field are so arranged, that the d.c. magnetic field cancels the external magnetic field. The magnitude of the a.c. magnetic field is varied within a predetermined range periodically to remove the residual magnetism.

摘要： A demagnetizing apparatus for removing residual magnetism in the body of an automobile which is equipped with a magnetic bearing indicator. A first and a second coil are wound around a substantially flat frame of a non-magnetic material to produce respectively a fixed d.c. magnetic field and a controllable a.c. magnetic field in orthogonal directions with each other and along flat surfaces of the substantially flat frame. The substantially flat frame with coils is positioned adjacent to but spaced from a body portion such as a roof, door or floor of the automobile, so that the d.c. magnetic field produced by the first coil cancel the external magnetic field caused by the terrestrial magnetism. The a.c. magnetic field is controlled to be intensified and weakened alternately thereby to remove the residual magnetism of the body portion without being influenced by the external magnetic field.

摘要： A vehicle's heading indicating apparatus includes a direction-finding sensor having a pair of external field sensing windings wound perpendicular to each other, a sensor exciting oscillator circuit, a signal sampling timing circuit, sample-and-hold circuits, comparators, a logic circuit and an indicator circuit. The output of each of the sensor windings is divided into predetermined (N+1) signal levels such that the heading or direction of travel of a vehicle is detected and indicated in accordance with the combination of each two signal levels sensing the heading, and also large disturbance of the earth's magnetic field is sensed such that the just preceding direction of travel obtained is indicated when the earth's magnetic field is excessively low or high. The apparatus further comprises an abnormal field sensing circuit for generating an abnormal field signal upon detecting that the heading sensing signals from the direction-finding sensor have exceeded a predetermined range of levels and an indicator gives an abnormal field indication in response to the abnormal field signal.
