Title: Color picture tube
Inventor: FUJIWARA TAKESHI
IPC: H01J29/76
Filed: 1989-08-04
Abstract: PURPOSE:To improve the focusing performance at end sections on the vertical axis of a fluorescent screen by correcting the distortion on a spot beam due to the barrel-shaped magnetic field generated by a vertical deflecting coil with the pin cushion-shaped magnetic fields generated by three pairs of two-pole permanent magnets. CONSTITUTION:Three pairs of two-pole permanent magnets 25a, 25b, 26a and 26b generate strong pin cushion-shaped magnetic fields 31 and 32 protruded on the center axis of a deflecting device 9, i.e., the path of an electron beam. The spot of the electron beam passing the magnetic field 31 generated by a pair of two-pole permanent magnets arranged in the vertical direction and reaching a fluorescent screen receives the Lorentz force distorted in an elliptic shape with a major axis in the vertical direction contrary to the Lorentz force received from the barrel-shaped deflection magnetic field 30, and phenomena that an ellipse is formed with the major axis in the horizontal direction of the beam spot based on the magnetic field 30 and a pair of side beams are inclined are corrected. A correcting device can be simplified and miniaturized with mass productivity due to the correcting effect of the beam spot by a pair of upper and lower magnets 25a and 25b.

Filed: 1985-09-17
Abstract: PURPOSE:To enable the titled device to stably evaporate the substance to be vapor- deposited by a method wherein an electron bombardment, divided into two parts on the outer circumference and the bottom part of the cylinder part of a crucible, is provided as the heating source of the crucible, and the temperature on the bottom side of the crucible is made higher than that of the other part. CONSTITUTION:The heating energy generated by the electrons, emitted from the filaments 7 and 28 to be used for the first and the second electron bombardment, is controlled in such a manner that the temperature of the liquid phase of the substance 4 to be vapor-deposited located in a crucible 5 is always maintained higher than that of the other part by giving an electron impact to the cylinder face side and the bottom face side of the crucible 5 at the ratio computed in advance. Accordingly, a liquid-phase substance, including the material with which the crucible 5 is formed, is coexisted in the substance 4 to be vapor-deposited by dissolution is circulated by convection. As a result, the formation of a film floating on the surface of the liquid-phase substance in the crucible 5 can be prevented even when the specific gravity of the material with which the crucible 5 is formed is lighter in weight than that of the substance 4 to be vapor-deposited, thereby enabling the substance to be vapor-deposited to evaporate in a fixed quantity at all times.
