Abstract:
A minute magnetic body detecting sensor includes: a magnetic impedance element, with two magneto-sensitive bodies disposed in substantially two-dimensional directions such that an angle formed by respective sensitive axes is substantially 90 degrees; and a signal processing device, including a signal processing circuit, processing and amplifying damped oscillating voltages output by the two magneto-sensitive bodies that detected a local magnetic field due to a minute magnetic body that is a foreign substance, two square operating elements, squaring output signals, an adder, adding the squared signals, and a square root operating element, performing square root computation on the addition output and outputting a square root output, and enables high-precision detection of existence or non-existence of a minute magnetic body without detection overlooking.

Claim (Index 8):
A foreign substance detecting device comprising\n a magnetic detecting element for outputting a voltage in response to a local magnetic field generated by a magnetized minute magnetic body positioned around a magneto-sensitive body of an amorphous material to which an electrical pulse current or an alternate current is applied, a signal processing device for processing the voltage to output an output signal, and a display device for displaying on a display portion based on an output signal of said signal processing device, wherein said magnetic detecting element comprises at least two magneto-sensitive bodies which are disposed on a plane such that sensitive axes of maximum sensitivity directions thereof are mutually different directions, and a plurality of said magnetic detecting elements are disposed with distances in a detection region in the same plane, and wherein said foreign substance detecting device is configured such that said signal processing device obtains the amplitude of the local magnetic field generated by the minute magnetic body by processing based on the voltage output in response to the local magnetic field of the minute magnetic body detected by said magnetic detecting element in case of a foreign substance of a magnetized minute magnetic body entering in inspected object placed on said detection region, and said display device displays the foreign substance of the magnetized minute magnetic body entering in the inspected object placed on said detection region on said display portion.
