Title: Discharging time constant setting device for envelope exchange
Inventor: TAKAZAWA ATSUYUKI
IPC: H03D1/10
Filed: 1989-12-12
Abstract: PURPOSE:To easily set a time constant by controlling the discharging time constant of a time constant circuit by a clock signal. CONSTITUTION:For a capacitor CD of a switched capacitor (SC)6, one electrode of a capacitor C is rotationally connected through a switch SW to the ground by the clock signal of a frequency (f). Therefore, at a certain moment, the potential of the capacitor CD is charged at the same potential as that of the capacitor C and at the next moment, the potential is connected to the ground and discharged to the zero potential. According to how many times this switch SW is rotated by the clock signal, the amount of electric charges to be charged/ discharged is determined. Accordingly, the discharging time constant of the capacitor C can be controlled by the frequency (f) of the clock signal. Thus, the time constant can be set by simple configuration.

Title: Electron gun
Inventor: YASUI SUKEYUKI
IPC: H01J37/077
Filed: 1990-11-28
Abstract: PURPOSE:To perform easy adjustment of the intensity of an electron beam and reduce the capacity of a power supply connected to a cathode, by providing a magnetic field generating device for generating a magnetic field parallel to the longitudinal direction of a wire placed in an ionization chamber. CONSTITUTION:When a pulsive voltage is applied between an anode wire 1 provided in an ionization chamber 3 and the wall 4 of the ionization chamber, and also applying the same voltage to a magnetic field generating device 20 synchronously, a gas in the ionization chamber 3 is ionized by a pulsive discharge to generate electrons and the resulting electrons move in spiral motion in the longitudinal direction of the anode wire 1. As the result, collisions with gas atoms are so promoted that ionization efficiency is increased as well as a plasma density. Thus, even if the same electron beam intensity is required as in a conventional device, ionic current can be increased by generating a magnetic field parallel to the longitudinal direction of the anode wire 1 by the magnetic field generating device 20. Consequently a negative biasing voltage V applied to a cathode 7 and a pulsive voltage applied to the anode wire 1 can be reduced so that a power supply capacity can be reduced.
