PURPOSE:To enable to obtain the pulse great in the output voltage and less in the dispersion, by giving a tension to the wire of ferromagnetic substance having positive magnetostriction and generating pulse voltage to the coil surrounding this wire through the magnetic change. CONSTITUTION:A tension is given to the wire of ferromagnetic substance having positive magnetostriction and coil is wound at the external side of the wire of ferromagnetic substance and they are placed at a magnetic field. The magnetization is changed at a given magnetic field and pulsative voltage is produced in the coil. In this case, since the dependancy of voltage on the speed of magnetic field change is very small, the pulses having great output voltage and less dispersion can be obtained. |
