Abstract: PURPOSE:To prevent the decrease in resolution caused by electron current control using a simple construction by arranging a fore electrode between an accelerating electrode and a focusing electrode, facing a back electrode constituting a part of the focussing electrode and interposing a secondary electron emitting layer between both the fore and back electrodes. CONSTITUTION:A fore electrode 13 is arranged between an accelerating electrode 3 and a focusing electrode 5 which a back electrode 14 constitutes the side part of. A secondary electron emitting layer 12 is interposed between both the electrodes 13 and 14 facing each other and formed into a cylindrical shape having a diameter nearly equal to each of the diameters of the beam passing holes 13a and 14a.

Abstract: PURPOSE: To allow a nonload operation regulation, regardless of an output signal of a regulator, by making a limit value signal of a throttle valve a value required for the nonload operation regulation when at least an electronic velocity control or control systems are interrupted. CONSTITUTION: When a control circuit 7 is normally operated, a switch 18 is closed, pulses supplied to an output stage 4 from an operation regulator 1 via a line 16 and pulses via a line 17 are operated in a direction closing a throttle valve and in a direction opening the throttle valve, respectively, by an operation element 2, and the opening of the valve is set according to the proportion of pulse width. At this stage, when a switch signal S becomes a regulating interruption level due to a braking operation and failures, a limit value signal G in a nonload operation regulation is supplied to a comparator 19 from a limit value circuit 20. When an actual value signal Xd is larger than G, the switch 18 remains closed and when the actual value signal Xd becomes higher than a maximum allowable opening degree, Xd<G is fixed and the switch 18 is opened.  By repeating this operation, a nonload operation regulation is performed. Thus, a safety circuit can be realized by a few components.
