with image screen generating a composite electron beam which is deflected as a whole past a stationary probe to simulate a scanning effect, e.g. Farnsworth pick-up tube

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Cathode-ray tubes; Electron-beam tubes > having a screen on or from which an image or pattern is formed, picked-up, converted, or stored > Image pick-up tubes having an input of visible light and electric output > with image screen generating a composite electron beam which is deflected as a whole past a stationary probe to simulate a scanning effect, e.g. Farnsworth pick-up tube

CPC:

Cathode ray tubes; Electron beam tubes (H01J25/00, H01J33/00, H01J35/00, H01J37/00 take precedence; details of cathode ray tubes or of electron beam tubes H01J29/00) > having a screen on or from which an image or pattern is formed, picked up, converted, or stored > Image pick-up tubes having an input of visible light and electric output (tubes without defined electron beams and having a light ray scanning photo-emissive screen H01J40/20) > with image screen generating a composite electron beam which is deflected as a whole past a stationary probe to simulate a scanning effect, e.g. Farnsworth pick-up tube

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
