  • Low consumption cathode structure for cathode ray tubes
    Patent number: 7439664
    Abstract: Cathode structure for cathode ray tube comprising an eyelet in two separate parts positioned such that one of the parts covers, in the longitudinal direction and at least partially, the second part. The two parts are linked to each other at the shouldered ends. This structure reduces the heat losses of the cathode and reduces its consumption while it is operating.
    Type: Grant

  • Cathode structure and electron gun for cathode ray tubes
    Patent number: 6369494
    Abstract: The invention relates to a cathode structure intended to be inserted into an electron gun for a cathode-ray tube. The cathode comprises a cathode body on the end of which is placed an emissive pellet, the cathode body being held in place inside a sheath by supporting means which comprise: a first series of branches, each branch being connected on one side to the cathode body and on the other side to an intermediate piece 30; and a second series of branches, each branch being connected on one side to the sheath and on the other side to the same intermediate piece.
