摘要： A beam-index tube apparatus comprising a beam-index picture tube provided with an electron gun to generate an electron beam of an oval cross-section, a deflecting device having a deflecting yoke for deflecting the electron beam, and correcting elements provided in the proximity of a front end of the deflecting yoke and positioned corresponding to the horizontal axis and the diagonal axes of the picture tube. The correcting elements act upon the electron beam in a manner such that the rotating of the diagonally deflected electron beam and widening of the horizontally deflected electron beam are thereby corrected.

摘要： A beam-indexing color image-presentation cathode ray tube comprises color-phosphor stripes arranged in a regular order and differently responsive to impingement by electron beams to produce light of different colors and index-phosphor stripes arranged to have a predetermined geometric relation to the color-phosphor stripes and responsive to impingement by the electron beams to produce index signals, in which the index-phosphor stripes comprises a first index-phosphor stripe, a second index-phosphor stripe and a third index-phosphor stripe, the pitch of the second index-phosphor stripe is three times as large as the pitch of the third index-phosphor stripe, and the first index-phosphor stripe is wider in its width than the second index-phosphor stripe.
