WIPO Patent Application WO/1999/048127

Kind Code:

A1

Abstract:

A yoke portion (Y) fitted with a deflection yoke (20) has a cross section vertical to the tube axis (Z) of which the shape is generally rectangular and non-circular. A core portion (24) of the deflection yoke (20) has a cross section vertical to the tube axis (Z) of which the shape satisfies: (M+N)/(2*(M?2¿+N?2¿)?1/2¿)$m(f)(SB+LB)/(2DB)$m(F)0.90 where M and N are the numerator and denominator of the aspect ratio, SB is the inner diameter along the vertical axis, LB is the inner diameter along the horizontal axis, and DB is the maximum diameter.
