摘要： To provide a magnetic position detecting device which is capable of extremely accurately detecting a reference position. In a magnetic position detecting device for detecting a position of a moving body 2 to a fixed body 1 on the basis of a change of a magnetic flux density that a Hall element 4 senses when the moving body 2 provided with a magnet 6 and the fixed body 1 provided with the Hall element 4 move relatively to each other. An S-pole and an N-pole of the magnet 6 are juxtaposed along a direction in which the magnet 6 and the Hall element 4 move relatively to each other. When the Hall element 4 passes a boundary position between the S-pole and the N-pole of the magnet 6, a magnetic flux density that the Hall element 4 senses is zero. The polarities of the magnetic field are completely inverted. Therefore, a variation of the position where the magnetic flux density sensed by the Hall element 4 is zero is completely eliminated. Only during a fixed period that the magnet 6 and the Hall element 4 mutually approach, a detect signal which depends on a magnetic flux density sensed by the Hall element 4 is compared with a reference signal. By detecting a position where both the signals are equal in level, a reference position is considerably accurately detected.

摘要： A rotation sensor functioning as both a rotation-angle sensor and a torque sensor is provided which, when applied to a steering sensor for an automobile, for example, permits reduction in the number of components and thus in the weight of the automobile and contributes to conservation of global environment. The rotation sensor has slip rings covered with conductive synthetic resin having small coefficient of friction, allowing the contact pressure of brushes disposed in sliding contact with the slip rings to be kept low and the life duration of the slip rings to be prolonged. Further, no metal powder is produced when the brushes slide on the respective slip rings, and it is therefore possible to prevent the formation of unwanted insulating film.

摘要： According to the invention, a magnetoresistive sensor for scanning a magnetic multipole wheel is proposed, which scans many uniformly disposed magnetic pole pairs. The sensor has four magnetoresistive resistors, which are connected electrically as a Wheatstone bridge with two half-bridges and which output a sine-wave and cosine-wave signal, respectively. To suppress the third and/or fifth harmonic of the scanning signal, it is proposed that the spacing between the two half-bridges be selected such that it is not equal to half the wavelength (lambda). For the third harmonic, the spacing dnulllambda/3 is preferably selected, so that the half-bridges are offset by a phase angle of 120null. To suppress the fifth semiharmonic, three identical sensors with a suitable spacing are connected together. The measured signals are averaged, so that the result is a field course with the third and fifth harmonics filtered out.
