Title:
METHOD FOR DETECTING CONSTITUENT MEMBER COMPRISING FERROMAGNETIC MATERIAL AND CIRCUIT DEVICE
Document Type and Number:
Japanese Patent JP2003042804
Kind Code:
A
Abstract:
To develop a method for detecting a constituent member comprising a ferromagnetic material and a circuit device, and to connect the advantage of an induction type sensor with the advantage of a digital sensor.
In the method for detecting the constituent member comprising the ferromagnetic material, a change in the inductance of a sensor caused by the constituent member is evaluated for detection.
