    Abstract: A cathode-ray tube has a faceplate panel joined to a funnel. An internal magnetic shield is disposed within the tube and is connected to a bottom surface of a flange of a shadow mask frame. The flange of the shadow mask frame has a plurality of integral shield-retaining clips formed therein. Each of the clips overlaps at least a portion of the shield, to retain it in contact with the flange of the frame.

    Abstract: An apparatus for electron beam deflection in a cathode ray tube, in particular in a picture tube of a television set, comprises a deflection coil arrangement for horizontal and vertical deflection of the electron beam, an auxiliary deflection coil arrangement, by means of which the electron beam can be influenced for the purpose of convergence correction, and a compensation coil arrangement for producing a magnetic compensation field. The compensation coil arrangement is arranged and designed such that the compensation field essentially compensates for the stray magnetic field of the deflection coil arrangement in the physical region of the auxiliary deflection coil arrangement.

    Abstract: An improved microelectromechanical device includes an upper plate, a lower plate, and a spacing structure. The upper plate includes a first surface and an opposite second surface. The lower plate is spaced from the upper plate. The lower plate includes a third surface that faces the first surface of the upper plate and a fourth surface that is opposite of the third surface. The lower plate also includes a series of structures disposed with the third surface of the lower plate. The spacing structure is coupled to the upper and lower plate. The spacing structure includes a base portion that is sealed to the first surface of the upper plate and the third surface of the lower plate. The spacing structure further includes a protrusion that extends from the base portion between the upper and lower plates.

    Abstract: A method of degaussing a cathode ray tube where two pairs of degaussing coils are arranged with one pair located at the top and bottom and the other to the right and left of the cathode ray tube after impaired color purity correction process of an electron beam has been carried out for the cathode ray tube using a magnetization process with a magnetization including an anticipated amount of degaussing for the cathode ray tube when the cathode ray tube is incorporated in a display device. The degaussing of a magnetic material within the cathode ray tube is then carried out with the anticipated amount of degaussing using the degaussing coils. In this way, a color cathode ray tub with no impaired color purity can be provided because the cathode ray trajectories corrected by magnetization in the magnetization process is not easily changed during use after incorporation in the display device.
