Title: Pulse generator
Inventor: MOURI KANEO
IPC: H02N11/00
Filed: 1981-12-30
Abstract: PURPOSE:To save an electric coil generating electric pulses, to attain small size and to improve the S/N, by using the Mathieu's effect. CONSTITUTION:Terminals 6a, 6b are fixed to permanent magnets 21, 22 fixed to a rotor 1, and a thin amorphous magnetic substance 5 is pressed to the terminals 6a, 6b in the state that the substance 5 is twisted twice and pulled in forcedly. As the rotor 1 turns, the permanent magnets 21, 22 are turned and an alternating magnetic field is applied to the lengthwise direction of the substance 5. Since a potential difference is caused between the twisted ferromagnetic substances in a magnetic field (Mathieu's effect), a sharp pulse voltage is generated every time the magnetic field is inverted.
