摘要： A cathode ray tube has a vacuum enclosure including a panel (1) having a screen (1a), a funnel (2) connected to the panel (1), and a neck (3) connected to the narrow part of the funnel (2). The funnel (2) has a yoke-mounting portion (5) on which a deflection yoke (7) is mounted. The sectional shape of the yoke-mounting portion (5), cut by a plane perpendicular to the tube axis of the funnel (2), varies from a circular shape to a substantially barrel shape having a maximum dimension at least in a direction of the horizontal axis or the vertical axis, as the position shifts from the neck (3) side to the panel (1) side of the yoke-mounting portion (5). With such an arrangement, the resistance to the external pressure can be improved, and the deflection power consumption can be reduced.

摘要： A color CRT device having a cathode ray tube and a deflection coil. The cathode ray tube includes a panel provided with a phosphor surface which has a diagonal diameter of 45 cm or more and has an aspect ratio greater than 4/3 and an electron gun having a high-voltage electrode and a focusing electrode which is disposed in proximity to the high-voltage electrode across a gap. The deflection yoke includes a core which cross-section perpendicular to a tube axis of the cathode ray tube is approximately annular; a saddle type first deflection coil for deflecting in a horizontal direction an electron beam, and a toroidal type second deflection coil for deflecting in a vertical direction the electron beam. The color CRT device satisfies a following relational expression: ##EQU1## where L mm denotes a distance between a central position of the gap and an end surface of the core on a side of the stem, D mm denotes an inner diameter of the core on the side of the stem, .theta. denotes a maximum deflection angle of the cathode ray tube, and K denotes the aspect ratio.
