PCT No. PCT/JP96/02795 Sec. 371 Date May 27, 1997 Sec. 102(e) Date May 27, 1997 PCT Filed Sep. 27, 1996 PCT Pub. No. WO97/12213 PCT Pub. Date Apr. 3, 1997Drawing two virtual lines passing through the center of a rectangular thin plate, made of a ferromagnetic material such as a permalloy, in directions deflected 45 degrees to the right and left relative to the horizontal/vertical lines, right, left, upper and lower edge areas between the two virtual lines of the thin plate are cut out to form notches. Edges of the notches do not contact the virtual lines. A coil wire is wound utilizing bottom lines of the individual pairs of opposing notches across the center to form an excitation coil and an output coil. With this construction, coil winding can be easily achieved by a robot rather than manually. This thereby considerably reduces the production cost and provides improved product quality and measurement accuracy. |
