摘要： A torque measuring system can detect the magnitude of a torque applied to a torque sensing shaft and output a torque signal with respect to the torque. A torque sensor of the system has a measurement mode for producing torque signals and a correction mode for correction of its detection characteristics. An external signal for selection of one of the two modes is supplied to the torque sensor by a characteristic check device. The correction mode enables the correction of the torque sensor characteristics to be effected accurately and in a short time period without requiring manual labor.

摘要： A method for zero correction in torque sensors, such as magnetostrictive torque sensor and strain gauge type torque sensor. Torque measurement is initiated when absolute values of torque signals are greater than a first set value, sampling measurement is carried out at predetermined intervals after the initiation. After absolute values of the measured torque signal values become lower than a second set value, an average value for a predetermined number of torque signal values whose absolute values are lower than a third set value is set as a new zero. The method permits proper measurement and correction of zero signals from torque sensors employed succesively at locations subject to impulse-like action of a torque load.

摘要： A sound attenuating system for attenuating sound from a sound source. The system comprises a main conduit through which the sound from the sound source propagates; a first device for defining in the conduit at least one passive acoustic reflecting surface; and a second device for defining in the conduit a plurality of active acoustic reflecting surfaces. The active acoustic reflecting surfaces are of a type which permits a partial permeation of sound therethrough.

摘要： An acoustic conductance is formed with oscillatory planes parallel to a duct and disposed on an identical circumference of the duct along a plane intersecting at right angles the duct so that the total area of the oscillatory planes will be substantially more than twice as large as a sectional area of the duct. The acoustic conductance is thereby made less affective on a fluid and provides a pertinent disposition of the acoustic conductance.
