Document Type and Number:
Japanese Patent JP2840614
Kind Code:
B2
Abstract:
The problems are resolved of temperature holding in both the anode (2) and the cathode (1) by making a flat cathode (7) engraved in a device (8) for running focusing. It is shown that, depending on the shape of this device, the heat flow at the anode is constant whatever the charge of the tube.
