摘要： 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.

摘要： Disclosed is a deflection yoke (24) mounted around a glass bulb (20) of a CRT (10) so as to cover a predetermined area of the glass bulb. The predetermined area is where an outer shape of the glass bulb smoothly goes from circular to substantially rectangular along a tube axis of the CRT. The deflection yoke includes a horizontal deflection coil (40) disposed in a shape to fit with the outer shape of the glass bulb, and a funnel-shaped ferrite core (38) disposed to surround the horizontal deflection coil. The inner shape of the ferrite core is circular throughout a length of the ferrite core.
