Method of and apparatus for generating a pulse signal |
摘要 |
A pulse signal generator comprising a magnetic element (1) able to cause a large Barkhausen jump; a detection member (2) for detecting a magnetic change in the magnetic element (1) to generate a pulse signal; and a pair of magnets (3, 4) provided on both sides of the magnetic element (1) such that their poles are opposed to each other; a magnetic circuit formation adjusting member (8, 9) attached to at least one of the magnets (3) so that when an object (5A) passes a pair of poles (3A, 4A) on one end of the magnets (3, 4), a magnetic field applied to the magnetic element changes to cause a large Barkhausen jump in the magnetic element (1), thus causing the detection member (2) to generate a pulse signal.
