摘要： The invention provides a novel color cathode ray tube apparatus incorporating an eight-pole permanent magnet means, and thereby deflective aberration of electron beams caused by deflected magnetic field can securely be minimized. Integral structure of a plurality of magnetic poles permits the concerned to easily form up the eight-pole permanent magnet ring.

摘要： In a cathode ray tube, a first pair of permanent magnet pieces are arranged along a horizontal direction and fixed on an end portion of a deflection unit at an electron gun side in such a manner that poles of one of the magnet pieces face the other poles of the other magnet piece. A second pair of permanent magnet pieces are arranged along a vertical direction, separated from the first pair of permanent magnet pieces by being fixed on a neck portion, forward of the electron gun assembly, and in such a manner that poles of one of the, magnet pieces face the other poles of the other magnet piece.

摘要： A color picture tube has: an envelope; a phosphor screen formed on the inner surface of the envelope; a shadow mask which is disposed in the envelope and in a vicinity of the phosphor screen and which has a main surface portion with a number of apertures; and an electron gun for emitting electron beams which are selectively transmitted through the apertures and are bombarded on the phosphor screen so as to emit multi-color light. A layer having a ceramic material as a major constituent is chemically bonded to that surface of the main surface portion of the shadow mask which is located at the side of the electron gun, and a conductive layer is formed on the layer. The charge-up phenomenon of the layer having a ceramic material is prevented by the conductive layer.

摘要： An inner shield made of a magnetic material for shielding the earth magnetism is provided in a color picture tube for preventing the mislanding of the electron beams on phosphor stripes that might otherwise result from the bending of the electron beams caused by the earth magnetism. The inner shield is formed by securing a pair of short side sections and a pair of long side sections to a mask frame such as to define a substantially rectangular space through which the electron beams pass. Gaps offering increased magnetic reluctance are provided between the short side sections on one hand and the long side sections on the other hand, whereby the components of the horizontal earth magnetic field vector are adjusted to cancel electromagnetic forces acting upon the electron beams.
摘要翻译：由用于屏蔽地磁的磁性材料制成的内屏蔽件设置在彩色显象管中，用于防止电子束在由地磁引起的电子束的弯曲所导致的磷光体条纹上的错落。内屏蔽件通过将一对短边部分和一对长边部分固定到掩模框架而形成，以限定电子束通过的大致矩形的空间。另一方面，在短边部分和长边部分之间提供增加的磁阻的间隙，由此调整水平地球磁场矢量的分量以消除作用在电子束上的电磁力。
