    摘要： An outer cylindrical section is rotatable with a first shaft. Magnetic shielding portions are formed of a magnetic shielding or antimagnetic substance and arranged on a surface of a nonmagnetic and nonconductive cylindrical base. The magnetic shielding portions are spaced apart from each other by a predetermined interval in a circumferential direction of the cylindrical base so that non-magnetically-shielding portions are formed between the magnetic shielding portions. A plurality of coils are provided on a periphery of the outer cylindrical section and excitable by a predetermined A.C. signal. An inner cylindrical section is inserted in the outer cylindrical section and rotatable with a second shaft. The inner cylindrical section includes magnetic portions each provided to present a different characteristic with respect to an arrangement of the plurality of coils. Degree of overlap between the non-magnetically-shielding portions of the outer cylindrical section and the magnetic portions of the inner cylindrical section varies in response to a variation in the relative rotational position between the first shaft and the second shaft, and each of the coils presents impedance corresponding to the degree of overlap.

    摘要： Single coil to be excited by a predetermined A.C. signal is provided, with no secondary coil being provided. Magnetism-responsive member is movable relative to the coil so that a self-inductance of the coil progressively increases or decreases in response to displacement of an object to be detected within a predetermined range and a voltage of the coil corresponding to the self-inductance is produced. Predetermined reference voltage is generated and subjected to analog operations with the coil output voltage, to thereby generate first and second A.C. outputs having, as amplitude coefficients, first and second cyclic amplitude functions correlated to the position to be detected. The position is detected on the basis of the phase component of the amplitude coefficient functions. Combination of two coils and one reference voltage may be employed.
