摘要： A coil section (10) includes a primary coil (11) which is magnetically excitable by an AC signal, and secondary coils (12 - 15) which are provided so as to generate an inductive output in response to excitation of the primary coil. A self-oscillation circuit (20), including an inductance element and a capacitor, has incorporated therein the primary coil (11) as the inductance element for self-oscillation. A target section (1) is provided in such a manner that its relative position to the coil section (10) varies according to a position of a target of detection, and the target section includes a magnetically responsive member disposed so that inductance of the secondary coils (12 - 15) is varied according to the relative position. Amplitude levels of the output signals of the secondary coils (12 - 15) are extracted, and position data of the position of the target of detection is obtained on the basis of these amplitude levels.

摘要： A phase detector is provided. The phase detector includes a signal selector, a bias level generator, and a phase information detector. The signal selector selects, as a selected sensor signal, one of a plurality of sensor signals each having a signal level corresponding to a phase of a rotor. The bias level generator divides a signal level difference between a pair of sensor signals, including the selected sensor signal and other sensor signal of the plurality of sensor signals other than the selected sensor signal, at a first ratio, to generate a first bias level. The phase information detector generates a threshold level corresponding to the phase of the rotor based on the first bias level, and detects the signal level of the selected sensor signal reaching the threshold level.

摘要： Improving reducing or eliminating the effects of variation in characteristics of the resonance circuit in a resonance type displacement detection apparatus, so as to improve displacement detection accuracy. In a displacement detection system 10, the resonance frequency range assumable by the resonance circuit 21 is estimated in advance, there is determined a drive frequency variation range f1 -f2 such that the estimated resonance frequency range is included therein, and by means of a variable oscillator 30, drive frequency is repeatedly varied between the first frequency f1 and the second frequency f2. Accordingly, where the resonance frequency of the resonance circuit 21 is fr1, when the drive frequency has changed to fr1, resonance voltage Vgl1 may be obtained in the case of large gap G. Where the resonance frequency of the resonance circuit 21 is fr2, when the drive frequency has changed to fr2, resonance voltage Vgl2 may be obtained in the case of large gap G.

摘要： A position detector that magnetically detects the position of a cylinder rod of construction machinery or industrial machinery, the position of the piston of an automobile, or the position of the scaler of a magnetic scale. This detector reduces the delay in response of a low-pass active filter. For this purpose, an average value operation circuit (22) is provided to determine the average value of the output voltage of a detector circuit (10) and supply a comparator (32) with the average value as a reference voltage. The detector includes an active low-pass filter in which diodes (D1, D2) are provided in parallel with resistors (R1, R2) filter to electrically charge the capacitors (C1, C2).
