Abstract: An improved deflection yoke for a cathode ray tube includes a cone-shaped separator, a ferrite core on an outer surface of the separator, vertical deflection coils wound around the ferrite core, and horizontal deflection coils on an inner surface of the separator, wherein the separator is an anisotropic plastic magnetic body that shields harmful magnetic flux generated in deflection coils and prevents distortion of the magnetic flux so that electron beams can be effectively deflected.

Abstract: Disclosure relates to a cathode ray tube formed in the neck portion of a funnel, which comprises an electron gun including a cathode, a control electrode and a screen electrode constituting a triode, and a magnetic substance formed between the cathode and the control electrode to focus the electron beam on the control electrode, so that the electron beam emitted from the cathode ray tube is focused toward an electron beam passing hole of the control electrode to improve the focussing characteristics and current density of the electron beam.

Abstract: A color cathode ray tube is taught having an improved spring type contactor. The spring type contactor effects electrical connection between a frame and a conductive coating deposited on the inner surface of the funnel, and comprises an `.OMEGA.` shaped fitting portion for being inserted into holes respectively perforated on the shield and the frame to be locked therein, a pair of legs abutting the edge of the hole of the shield, and a `C` shaped contact portion extended from one of the legs to contact with the conductive coating on the inner surface of the funnel. According to the present invention, the inner magnetic shield is conveniently affixed to the frame, and the electrical resistance between the frame and the conductive coating is diminished so remarkably that the residual electrons in the cathodoluminescent screen and the shadow mask can effectively by-pass to the conductive coating.
