A backlight unit, with a parallel configuration of plural lamps, having improved reliability is disclosed. The backlight unit driver includes: first and second lamps connected parallel to each other; a DC/AC inversion portion inverting a DC voltage into an AC voltage to apply the AC voltage to the lamps; a transformer transforming the AC voltage from the DC/AC inversion portion; a positive polarity AC signal compensator compensating an electric current difference between the first and second lamps using positive polarity AC signals from the first and second lamps; and a negative polarity AC signal compensator compensating the electric current difference between the first and second lamps using negative polarity AC signals from the first and second lamps.

A deflection yoke is provided for a CRT, which includes horizontal and vertical deflection coils that deflect electron beams emitted from an electron gun in a horizontal or vertical direction, a ferrite core that reduces a loss of magnetic force caused by the horizontal and vertical deflection coils thereby enhancing magnetic efficiency, and a holder that holds the horizontal deflection coils, the vertical deflection coils, and the ferrite core at required positions, and provides insulation between the horizontal deflection coils and the vertical deflection coils. The horizontal and/or vertical deflection coils have a substantially rectangular shape on a screen side, and the ferrite core is circular or elliptical. This reduces material costs and reduces convergence and distortion errors, because a dimensional distribution of an inside surface area of the ferrite core is reduced with respect to related art deflection yokes, and polishing of an inside surface becomes easier. This significantly improves production yield and the dimensional distribution of the ferrite core.

Deflection yoke for a CRT

In a deflection yoke for a braun tube deflecting an electron beam radiated from an electron gun to a screen and including a horizontal deflection coil, a vertical deflection coil and a ferrite core, the horizontal deflection coil is installed inside a funnel, the ferrite core is installed outside of the funnel, the vertical deflection coil is installed inside or outside of the funnel, accordingly the convergence and deflection sensitivity of an electron beam can be easily compensated, the deflection sensitivity of a braun tube can improve, and the degree of freedom in designing the deflection yoke and an electron gun related to enlarging a diameter of the electron gun can increase.

Deflection yoke for braun tube

A deflection yoke of Braun tube having a horizontal deflection coil for horizontally deflecting electron beams radiated from an electron gun, a vertical deflection coil for vertically deflecting the electron beams, and a holder inserted between the horizontal and the vertical deflection coils for mechanically fixing them and electrically insulating them, including: an auxiliary coil having a first deflection portion coil extendedly formed from a '3-o'clock' position of a neck side to a '3-o'clock' direction of a screen side on the basis of the lengthy direction of the deflection coil; a first flange coil extendedly formed for a predetermined length from a &lsquo;3-o'clock&rsquo; position of the screen side to a &lsquo;12-o'clock&rsquo; direction of the screen side; a second deflection portion coil extendedly formed for a predetermined length from a &lsquo;12-o'clock&rsquo; position of the screen side to a &lsquo;12-o'clock&rsquo; direction of the neck side; a second flange coil extendedly formed for a predetermined length from a &lsquo;12-o'clock&rsquo; position of the neck side to a &lsquo;9-o'clock&rsquo; direction of the neck side; a third deflection portion coil extendedly formed for a predetermined length from a &lsquo;9-o'clock&rsquo; position of the neck side to a &lsquo;9-o'clock&rsquo; direction of the screen side; a third flange coil extendedly formed from a &lsquo;9-o'clock&rsquo; position of the screen side to a &lsquo;6-o'clock&rsquo; direction of the screen side; a fourth deflection portion coil extendedly formed for a predetermined length from a &lsquo;6-o'clock&rsquo; position of the screen side to a &lsquo;6-o'clock&rsquo; direction of the neck side; and a fourth flange coil extendedly formed from a &lsquo;6-o'clock&rsquo; position of the neck side to a &lsquo;3-o'clock&rsquo; direction of the neck side. Accordingly, misconvergence of a deflection yoke of Braun tube can be complemented without using an additional circuit and power consumption is reduced.

Cooling device of a magnetron for a microwave oven, which includes a plurality of radiation fins disposed between an outer periphery of an anode cylinder and an inner surface of a yoke serving as a frame for radiating heat of a high temperature produced during osicillating operation of the magnetron for generating an electromagnetic wave. The temperature of the fins disposed centrally in substantially the same as the temperature of the fins disposed at both ends of the anode cylinder. This is accomplished by, the fins disposed centrally on the outer peripherey being arranged at a diffeent distance from the distance between the fins disposed on both ends of the anode cylinder or by the fins disposed centrally being made of different materials from the materials of the end.
