  • Patent number: 5367230
    Abstract: A cathode-ray tube has an electron gun disposed in its neck in confronting relationship to a phosphor screen through a deflection yoke mounted on the funnel. The electron gun has a cathode assembly for emitting three electron beams, and a main lens for passing the electron beams therethrough. The main lens includes a quadruple lens system responsive to focusing voltages for canceling an astigmatic effect produced on the electron beams when the electron beams are deflected by the deflection yoke, at a peripheral edge of the phosphor screen.

  • Patent number: 5361407
    Abstract: A superheterodyne receiver comprises a variable frequency oscillator of PLL (phase-locked loop) type for implementing a first local oscillator and a variable frequency oscillator not of PLL type for implementing a second local oscillator. At least the frequency of a first locally generated signal is varied at reception to vary a received frequency, the frequency of the first locally generated signal is set at frequency calibration to a level equal to the frequency of a first intermediate-frequency signal, the second intermediate-frequency signal is frequency-converted by a BFO signal to a signal having a frequency of voice band, and the frequency of a second locally generated signal is calibrated to set the frequency of the frequency-converted signal to a specified level.

  • Patent number: 5359265
    Abstract: A display apparatus for displaying a video image operates with plural horizontal scanning frequencies. The apparatus includes a horizontal scanning frequency oscillator for generating a signal in synchronism with a horizontal synchronous signal of an input video signal; and a control unit for controlling a frequency of an output of the horizontal scanning frequency oscillator corresponding to the horizontal synchronous signal of the input video signal. A multi-scan video monitor may be provided for displaying the image relative to any of the plural horizontal scanning frequencies without any turbulence.

  • Patent number: 5359421
    Abstract: A bezel which minimizes possible production of powder by rubbing thereof with a cathode ray tube to prevent possible deterioration of an appearance of a display unit in which the bezel and the cathode ray tube are assembled. The bezel has, around a substantially rectangular opening thereof, a contact area at which it is to contact with a cathode ray tube to which the bezel is to be assembled. The contact area is provided by a plurality of ribs formed in a suitably spaced relationship from each other on the bezel along an inner periphery of the opening in such a manner as to extend perpendicularly to the inner periphery of the opening. Some of the ribs which are provided along a pair or two pairs of opposing edges of the inner periphery of the opening may be replaced by different ribs which individually extend in parallel to the edges of the inner periphery of the opening.

  • Patent number: 5357545
    Abstract: When supplied with an external synchronizing signal from an input terminal (2), a synchronizing separating circuit (6) separates and detects a horizontal synchronizing signal from the input signal and generates an HD pulse. When supplied with the HD pulse, a flip-flop (9) is set to generate a pulse. This output pulse is integrated by an integrating circuit (8) and an integrated output from the integrating circuit (8) is used to adjust a width of an output pulse from the flip-flop (9) to a value corresponding to a horizontal scanning frequency. The flip-flop (9) can be set only when supplied with the HD pulse, thereby preventing the flip-flop (9) from outputting a pulse whose width is longer than the width of the HD pulse. Therefore, the length of the back porch can be prevented from being reduced more than it is needed.
