摘要： A device for measuring torque in a shaft without contacting the latter. A torque transmitting shaft is formed with at least one detecting magnetically anisotropic region inclined to form an angle with respect to the axis of rotation of this shaft. A detecting coil is disposed on the periphery of the detecting magnetically anisotropic region. When the detecting voltage for the detecting coil changes owing to temperature changes and time-dependent changes, the changes in the detection sensitivity and in the zero point take place, leading to errors during torque measurement. Correct measured values can be obtained by having a device for correcting such changes in sensitivity and zero point.

摘要： A stator coil for a rotating electrical machine having a ground wall insulation of a stator coil impregnated with a resin, maintaining a releasing characteristic between the ground wall insulation and a slot of a stator core, preventing surface corona and exhibiting excellent characteristics for a long time. The stator coil of the rotating electrical machine has a conductor covered with an insulating layer and a surface-corona preventive layer, the stator coil being accommodated in the slot of a stator core and, together with the stator core, impregnated with a thermosetting resin so that the stator coil is integrated with the stator core. The surface-corona preventive layer has a wound semiconductive tape and a composite tape including a fluorine-containing non-bonding material layer on a second semiconductive tape. The slot of a stator core and the insulating layer contact the semiconductive tapes and the non-bonding material is disposed between the semiconductive tapes, forming a gap in a widthwise direction of the non-bonding material layer.

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.
