摘要： Magnetic poles are provided continuously with a pitch .lambda. on the peripheral portion of a drum rotated in accordance with a movement of a moving body. A magnetic sensor is provided in opposition to these poles. The sensor is formed of two magnetoresistive element pairs which are spaced from each other at .lambda./6, and the two elements in each pair are arranged in positions spaced from each other at .lambda./2. The two elements in each pair are connected in series to form a bridge circuit. The signals obtained from the nodes of the series-connected elements in the two element pairs are differentially amplified so that third harmonic wave components are eliminated, and a signal having no distortion and representative of the position or speed of the moving body can be obtained.

摘要： A device for detecting a load torque using angle detectors fitted with a certain spacing on a shaft which is rotated by a drive source and on the basis of a relative angular difference of angles detected by the angle detectors. The device includes two rotary drums or discs fitted with a certain spacing on the drive side and load side of the shaft, with a plurality of magnetic poles for generating magnetic signals being formed on the surface thereof, and a magnetic sensor disposed to confront the surface of the rotary drums or discs, with magnetic resistance effect elements which vary in internal resistance in response to the magnetism of the magnetic poles being provided thereon. The amount of torsion created by the load on the load side of the rotary shaft is measured as a phase difference of outputs of the magnetic sensor, and the torque is detected in terms of the angular difference between the magnetic drums or discs. The device is operative to detect a torque in both storage and rotation, and capable of detection within a period of magnetic signal, whereby high-accuracy, high-resolution torque detection is made possible.

The rotary magnetic recording medium is divided into plural channels, each of which includes two tracks. A magnetic sensor is disposed to face the magnetic recording medium with a predetermined air gap therebetween and includes two sets of magnetoresistive elements spaced by a predetermined distance for each channel. Each set of magnetoresistive elements includes two elements wherein the first elements of the two sets face one of the tracks of a channel and the second elements of the other of the two sets faces the other track and the first and second elements of the two sets are formed as one body with adjacent ends of the first and second elements being coupled with each other. The coupled adjacent ends are connected to either one of first terminals for deriving output voltages from the magnetoresistive elements or to second terminals for supplying the magnetoresistive elements with source voltage. The non-adjacent ends of the first and second elements which are opposite to the coupled ends are connected to the other of the first and second terminals. In this manner, the sensor can be made small in size and the resistivity against noise is enhanced.

摘要： In a gate pulse generator for a thyristor converter of the type in which in order to fire thyristors of the thyristor converter in which each arm is comprised of a plurality of series-connected thyristors, the gate pulses are generated in response to the gate command signal and the thyristor forward voltage signal and are converted into the light signals which in turn are transmitted to the thyristor converter, whether or not the forward voltage signal exists when the gate command signal is generated is detected and when the forward voltage signal is generated prior to the generation of the gate command signal, the pulse duration is narrowed to a minimum required for firing the thyristor. When the forward voltage signal is generated during the time interval in which the gate command signal continues, the differences in time point when the forward voltage signals are generated among the thyristors due to the storage carrier differences therebetween are taken into consideration so that the pulse duration is increased. Therefore, from the standpoint of the frequency of occurrence, the thyristors can be fired in response to the pulse signal with a narrow pulse duration in almost all cases.
