Abstract
A deflection yoke for a CRT including a horizontal deflection coil having an axial length in an axial direction of the CRT in an installed position that is not less than 60 mm and not more than 80 mm, a vertical deflection coil having an axial length in an axial direction that ranges from 45 mm to 65 mm, and a core having an axial length in the axial direction that ranges from 25 mm to 45 mm. The subject deflection yoke prevents deterioration in horizontal and vertical deflection sensitivity in CRTs having a neck diameter that is greater than 22 mm and less than 26 mm with a deflection angle that ranges from 95 to 110 degrees. In an alternate embodiment a deflection yoke for a CRT including a horizontal deflection coil, a vertical deflection coil disposed outside of the horizontal deflection coil, and a core disposed outside of the vertical deflection coil wherein in an installed position of the yoke, an inner surface of the deflection yoke is circumscribed around a circle having a diameter of 56.5 mm and the horizontal deflection coil has a length thereof extending from the tube axial position to an opening end of the horizontal deflection coil ranges from 20.5 mm to 24.5 mm and a…
