記載のパルス発生装置。[Claims for Utility Model Registration] (1) Only the magnetization direction of the portion with relatively small coercive force can be shifted in the negative direction when the auxiliary magnet approaches and moves away, and this can be transferred to the negative direction of the next main magnet. This occurs based on the action of the auxiliary magnet and the main magnet, and a magneto-sensitive element made of a composite magnetic material that is treated to undergo extremely rapid dislocation when magnetized in the same positive direction as a portion with a large coercive force due to proximity. What is claimed is: 1. A pulse generator comprising a pulse detection coil for detecting pulses, characterized in that a bypass magnetic path for fine adjustment of a ferromagnetic material is provided near the auxiliary magnet. (2) In a pulse generator comprising a plurality of magnetically sensitive elements arranged around a rotor, and the auxiliary magnet, main magnet, and detection coil fixed to the stator side, a bypass magnetic path for fine adjustment of the ferromagnetic material is provided. The pulse generator according to claim 1 of the utility model registration claim, characterized in that the pulse generator is provided with: (3) arranging the auxiliary magnet and the main magnet on the rotor;
A pulse generator comprising a plurality of magnetic sensing elements and detection coils arranged around a stator,
2. The pulse generator according to claim 1, further comprising a bypass magnetic path for fine adjustment of the ferromagnetic material.
