摘要：Disclosed is a rectangular-shaped deflection yoke (what is called RTC (RoundCore Tetra Coil Combined Deflection Yoke) for enhancing deflection sensitivity of acathode-ray tube. More specifically, the present invention relates to a deflection yokestructure for the cathode-ray tube that is mounted with rectangular shaped deflection
coils and circular shaped ferrite cores, and the difference between a maximum gap and aminimum gap for the deflection coil and the ferrite core is biggest at an end section on ascreen side of the ferrite core
