    • PROBLEM TO BE SOLVED: To enable an eddy current type conductor detecting apparatus which detects a rotation number and a positional relation between itself and a conductor of a turbocharger or the like, to precisely detect the conductor by reducing output variations due to changes in temperature.
      SOLUTION: The eddy current type conductor detecting apparatus is equipped with a signal processing circuit which detects positional information of the conductor in relation to a coil based on a signal voltage output from an LC parallel connected circuit of the eddy current type conductor detecting apparatus. In the eddy current type conductor detecting apparatus, an output difference between outputs in high-temperature and low-temperature conditions has two identity points on a frequency axis, and a considerably large output difference can be ensured at frequencies of the two identity points in the high-temperature and low-temperature conditions. Therefore, if AC current having a frequency equal to one of the frequencies of the two identity points is applied to the LC parallel connected circuit, at least an output variation occurring between a prescribed low-temperature condition and a prescribed high-temperature condition can be canceled, thereby enabling any output error due to temperature changes to be canceled, and enabling the rotation number to be detected precisely regardless of the temperature changes.

    • PURPOSE:To make it possible to detect and judge a member to be detected even when two members to be detected are continued, by comparing the detection signal from the detection circuit based on a detection coil with the reference signal level and reference signal width set to a judge circuit. CONSTITUTION:When a member 4 to be detected is one, detection voltage V2 is smaller than upper limit set voltage VH and a lower limit pulse width TPL, wherein lower limit set voltage VL is a slice level, is smaller than an upper limit pulse width TPH and, therefore, a microcomputer 5 judges that the member 4 to be detected is one and outputs a pulse signal P8a showing one pulse to a passing output terminal 8 from an output circuit 7. When two members 4 to be detected are continued, because the lower limit pulse width TPL, wherein the lower limit set voltage VL in detection voltage V2 is the slice level, becomes larger than the upper limit pulse width TPH, the microcomputer 5 judges that two members 4 are continued and allows the output circuit 7 to output not only a pulse signal P8b to the passing output terminal 8 but also a high level continuous signal S10 to a continuous output terminal 10.

    • PURPOSE:To detect a metal body only by a transmission coil, in a series resonance circuit equipped with the transmission coil, a condenser and an oscillation circuit, by setting the frequency of an oscillator to resonance frequency generated when the metal body approached the transmission coil. CONSTITUTION:A series resonance circuit is formed of an oscillator 1, a condenser 2, a transmission coil 3 and a current detection resistor 13. This resonance circuit has a resonance curve B when the metal body is close to the transmission coil and has a resonance curve A when the metal body is not close. The frequency (f) of the oscillator 1 is set to the resonance frequency f1 of the resonance curve B. The metal body detection apparatus having this resonance circuit is embedded in the ground and, when a vehicle approaches said apparatus, an eddy current is generated to the vehicle by an AC magnetic field and the inductance of the resonance circuit is reduced to change a current from I1 to I2. As a result, voltage generated in the resistor 13 becomes large and the output of a rectifier 6 becomes larger than reference voltage 8 and a comparator 7 outputs the approach signal of the vehicle.

An eddy current loss in a metal detection body approaching the detection coil is detected depending on a high frequency magnetic field generated with the detection coil 1 as change in the oscillation amplitude. A detection head section is made up of a coil 9 buried direct into a metal pipe 10 thereby enabling reduction in the diameter.
