Abstract
Method for vaporizing getter material from a container inside a vacuum electron tube comprises (a) sensing the location of the container from outside the tube, (b) generating signals indicating that location, (c) positioning an induction heating coil outside the tube opposite the container, (d) energizing the positioned heating coil and (e) using the generated signals to control the energizing step.
Claims8
In a method for vaporizing getter material from a getter container located inside and adjacent the inner surface of the envelope of a vacuum electron tube, said method including
- (i) positioning an induction coil adjacent the outer surface of said envelope opposite said getter container
- (ii) and energizing the positioned induction coil so as to heat said getter container and to vaporize said getter material therefrom,
- the improvement comprising
- (a) sensing the location of the getter container from outside said envelope,
- (b) generating signals which indicate the location of said container
- (c) and using said signals to control said energizing step.
