摘要： A deflection yoke includes a bobbin having a cavity formed in the longitudinal direction of the bobbin, and an adjusting coil having a magnetic core on which a thread is cut. The core inserted into the cavity is slidable in the longitudinal direction of the bobbin. The core has a marker formed on only one of ends of the core in the longitudinal direction. The core has been inserted into the cavity from the one end formed with the marker or the other end. The marker is formed on only one of ends of the core before or after the thread is cut thereon.

摘要： A projection type cathode ray tube device includes a panel, a neck, a funnel connecting the panel to one end of the neck, and a stem closing the other end of the neck. An electron gun is housed in the neck for projecting an electron beam toward a phosphor screen on the panel. The neck includes a small-diameter neck portion disposed on its funnel side, a large-diameter neck portion disposed on its stem side, and a neck junction region connecting the small-diameter neck portion and the large-diameter neck portion. A deflection yoke is disposed in a vicinity of a transition region between the funnel and the small-diameter neck portion. A convergence yoke for generating a beam-convergence magnetic field is disposed to extend from the large-diameter neck portion and surround at least a portion of the neck junction region.

摘要： A display tube having a deflection coil support with a field deflection coil system at its outer side and a line deflection coil system at its inner side. The gun-sided end of the line deflection coil system is situated in a plane parallel to the wall of the display tube. The outer side of the coil support is surrounded by an auxiliary deflection coil system, preferably in a printed form, against the inner and for outer surface of a synthetic material supporting cylinder. This assembly, which can be used particularly for scan velocity modulation purposes, is at least partly arranged between the field deflection coil system and the wall of the display tube, while it partly overlaps the gun-sided end of the line deflection coil system.

摘要： In a color cathode ray apparatus, three electron beams emitted from electron gun assembly are correctly converged on a peripheral region of a peripheral region of a phosphor screen and are weakly converged on a center region of the phosphor screen by static convergence means. The electron beams are also converged by dynamic convergence means so as to correct the weak convergence in accordance with a horizontal deflection of the electron beams. Thus, the electron beams can be correctly converged all over the phosphor screen.

摘要： A color picture tube comprises the vacuumed tube envelope formed by a face plate having a plurailty of phosphor strips regularly formed on the inner surface, a funnel section having an enlarged end opening on which the face plate is mounted a skirt section on which deflection yoke is mounted and neck integrally formed with the funnel section and having located therein an electron gun assembly for emitting electron beams. A shadow mask having a plurality of slits therein is disposed to face to the inner surface of the face plate. The shadow mask is provided on an integral mask frame by which the shadow mask is secured to the inner surface of the tube envelope. The mask frame has an inner shield secured thereto along the inner circumference of the envelope. The inner shield is coupled to a permanent magnet member faced to the inner surface of the envelope. The member is to be preliminarily strongly magnetized and each section thereof is demagnetized and adjusted to a determined value to present a determined intensity of magnetism. The plate serves to change the path of the electron beams, thereby appropriately directing the electron beams toward the determined phosphor strips.
