    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.

    摘要: Disclosed is an in-line type color picture tube apparatus which comprises an in-line type color picture tube including a phosphor screen for displaying a substantially rectangular picture with horizontal, vertical, and diagonal axes and an in-line electron gun arranged in parallel with the horizontal axis so as to be allowed to cast electron beams on the phosphor screen to reproduce a color image, a deflection yoke disposed around the outer periphery of the tube and generating such a magnetic field that may give positive isotropic astigmatism to the electron beams when the electron beams are deflected along the horizontal axis, may give negative isotropic astigmatism to the electron beams when the electron beams are deflected along the vertical axis, and may give negative anisotropic astigmatism to the electron beams when the electron beams are deflected along the diagonal axes, and a correction deflection element formed of a plurality of permanent magnets arranged in the vicinity of the end portion of the deflection yoke on the phosphor screen side, generating such a magnetic field that may diagonally constrict the end portions of the diagonal axes of a raster formed of the electron beams by means of an action of the deflection yoke and give positive anisotropic astigmatism to the electron beams when the electron beams are deflected along the diagonal axes. According to this in-line type color picture tube apparatus, raster distortion may be corrected practically completely without using a correction circuit, and self-convergence system may be realized.
