Picture tube with an electron gun having an improved potential supplying means

A picture tube device comprising:

• an evacuated envelope comprising a panel, a funnel portion extending from said panel, and a neck portion extending from said funnel portion and terminating in a stem portion;
• an anode disposed on an inner wall of said funnel portion, an anode terminal positioned on said funnel portion, and a plurality of stem pins disposed on said stem portion;
• an electrode gun positioned within said neck portion, said electron gun comprising a cathode generating an electron beam and a plurality of grids for focusing and accelerating said electron beam, and potential means for supplying potentials to said anode through said anode terminal and to said cathode and grids through at least one of said stem pins;
• and,
• at least one glass supporting means for securely supporting said cathode and grids, said glass supporting means comprising a solid homogenous resistance glass body and at least one of said grids being embedded in and in direct connection with said resistance glass body, said resistance glass body being coupled to said anode and to another of said stem pins, whereby a potential is divided by said resistance glass body and is supplied directly to said one grid.
