IPC: H01J23/18
Filed: 1989-10-03
Abstract: PURPOSE:To achieve high conversion efficiency by composing a high frequency circuit with a hollow resonator part and a travelling wave transmitting waveguide tube part directly connected with down stream beam of the resonator part and operating the circuit while oscillated high frequency power level in the hollow resonator part is suppressed to sufficiently low against the high frequency electric power level which is a final output of the travelling wave transmitting waveguide tube part. CONSTITUTION:In a self resonating peniotron oscillator tube, distribution of behavior of each electron is within a narrow range when interaction of electron beam (e) and TE mode electromagnetic field proceeding to the electron beam (e) under the self resonating conditions of the hollow resonating part 13 is relatively weak. Then, previous oscillation with comparatively low electric power is carried out and an electron beam which passes the resonating part and resonation output are led to a signal wave transmitting waveguide tube part 14 so as to amplify them. In this waveguide tube part 14, in the same way in the oscillator tube, travelling wave and electron beam are interacted each other while self resonating conditions is maintained. By this method, not only rotation kinetic energy of electrons but also kinetic energy in axis direction contribute for amplification of the electromagnetic field and convedrsion efficiency at the whole of the resonating tube is heightened.

Abstract: PURPOSE:To attain to enhance the efficiency of a magnetic circuit and to increase the speed of a printing head by reducing leak magnetic flux without damaging the effect of a core-type magnetic circuit, by providing a magnetic leak part for leaking magnetic flux flowing to an armature and a yoke to the circumferential direction of a core with respect to the inner peripheral surface thereof. CONSTITUTION:A magnetic leak part 12a for reducing a demagnetizing current is provided to the inner peripheral surface of a core 12 constituting a magnetic circuit in opposed relation to a yoke 11 and an armature 3 so as to generate magnetic leak (a) to the circumferential direction of the core. By this constitution, the generated magnetic leak (a) is originally different from leak magnetic flux and this leak magnetic flux is suppressed as low as possible and, in its turn, the enhancement of suction force is achieved. Because the magnetic leak (a) opens a driving leaf spring 5, a current is made to flow to a demagnetizing coil 8 and an open current necessary for negating the energy possessed by a permanent magnet 10 is reduced. If the quantity of the magnetic leak (a) becomes too large, the suction force characteristic of the magnetic circuit is lowered and, therefore, otpimum magnetic leak quantity is set by adjusting the distance (l) between the leak part 12a and the yoke 11/armature 13 and the opposed area (s) of the leak part 12a.
