the switching device being a vacuum tube

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Circuits for generating electric pulses; Monostable, bistable or multistable circuits > Generators characterised by the type of circuit or by the means used for producing pulses > by the use of an energy-accumulating element discharged through the load by a switching device controlled by an external signal and not incorporating positive feedback > the switching device being a vacuum tube

CPC:

Circuits for generating electric pulses; Monostable, bistable or multistable circuits (H03K4/00 takes precedence; for digital function generators in computers G06F1/02) > Generators characterised by the type of circuit or by the means used for producing pulses (H03K3/64 - H03K3/84 take precedence) > by the use of an energy-accumulating element discharged through the load by a switching device controlled by an external signal and not incorporating positive feedback (H03K3/335 takes precedence) > the switching device being a vacuum tube

No child classifications to compare. This is a leaf node in both IPC and CPC.
