Full Title
Full titles differ between systems:
IPC:
Cathode-ray tubes; Electron-beam tubes > having one or more output electrodes which may be impacted selectively by the ray or beam, and onto, from, or over which the ray or beam may be deflected or de-focused
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 one or more output electrodes which may be impacted selectively by the ray or beam, and onto, from, or over which the ray or beam may be deflected or de-focused
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
