    摘要: Method for producing a magnetostrictive torque sensor shaft and a torque sensor shaft made according to the method. Knurl grooves are formed on the surface of shaft base material in oblique relation to the axis thereof, which are then subjected to heat treatment. Subsequently, material having less crystallomagnetic anisotropy and a large magnetostriction constant is deposited by plating, thermal spraying or otherwise at least on the surface of the knurl grooves included in the outer periphery of the shaft base material thereby to form a magnetostrictive layer. Preferably, the magnetostrictive layer is comprised of an FeNi alloy plated layer whose Fe component content is more than 0% but less than 25%. Thus, a sensor shaft is obtained which can be suitably used in constructing a magnetostrictive torque sensor having high performance characteristics. In order to improve the bond between the shaft base material and the magnetostrictive layer, it is preferable to subject the surface of the shaft base material to surface treatment such as shot peening and/or nickel strike plating, prior to the step of magnetostrictive layer forming. This surface treatment makes it possible to obtain a torque sensor having good service durability.

    摘要: A torque sensor shaft for a non-contacting torque sensor including magnetically anisotropic portions formed on the surface of the shaft. Absolute value of angle of inclination of the anisotropic directions of the magnetically anisotropic portions is set lower than 40 degree so as to permit reduction of stress components in the anisotropic directions from their level in the case where the absolute value of the angle is 45 degree. By such angle setting it is possible to prevent possible decrease in sensor sensitivity and, in addition, to obtain good improvement in the point of magnetic saturation due to torque applied, thereby to obtain an improved dynamic range.

    摘要: This invention relates to a vernier drive mechanism, in which a vernier shaft always being subjected to the elasticity of a coil spring is put into a hollow part of a main shaft in a freely rotatable manner, a housing is put outside the main shaft also in the freely rotatable manner, a part having a hexagonal section or a shape causing the similar effect is made at the center of the main shaft, holes open to the hollow part of the main shaft are made on the three planes placed radially at the same angle of the six peripheral planes, balls are put into the holes and are made to contact with a small diameter part of the vernier shaft and the inner surface of the housing by the elasticity of the spring so as to rotate planetarily by the rotation of the vernier shaft and to turn the main shaft at a speed slower than that of the vernier shaft.

    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: Whether a pixel of interest contained in applied image data exhibits color bleed (a false color or purple fringe) is determined. If the pixel of interest is determined to exhibit color bleed, a direction along which luminance is monotonically decreasing in the vicinity of the pixel of interest is discriminated using the pixel of interest as a starting point. A search is performed in the direction of monotonically decreasing luminance to find a pixel where the monotonic decrease in luminance ends. The found pixel where the monotonic decrease in luminance ends is decided upon as a target pixel and a correction value for causing the color of the pixel of interest to match the color of the target pixel is calculated. The color of the pixel of interest is corrected using the calculated color correction value.
