  • Cathode ray tube device
    Patent number: 6489734
    Abstract: A cathode ray tube device includes: a cathode ray tube with an envelope including a panel having a phosphor screen on its inner face and a funnel having a neck portion including an electron gun; and a deflection unit disposed around an outer face of the funnel. An inductance-adjusting element is provided therein for reducing an inductance at a frequency in an audio frequency band of at least one of a plurality of coils included in the deflection unit, and thereby noise is reduced that is generated by the at least one of the plurality of coils whose inductance is thus reduced.
    Type: Grant
    Filed: April 25, 2001
    Date of Patent: December 3, 2002
    Assignee: Matsushita Electric Industrial Co., Ltd.
    Inventors: Shunsuke Matsuura, Asato Aoki, Kazuhiro Sugimoto
