摘要： A television camera tube with electrostatic focusing and magnetic deflection comprises in an cylindrical envelope a beam current control, a main lens section and a sixth grid in the form of a mesh electrode. The beam current control section includes a cathode, a first grid and a second grid with an electron beam limiting diaphragm in this order. The main lens section includes third, fourth and fifth grids in the form of cylindrical electrodes disposed in this order. Around the cylindrical envelope is mounted a magnetic deflection coil whose length along the envelope axis is 0.18 to 0.40 times the distance from the beam limiting diaphragm to the mesh electrode.

摘要： A flat display panel uses a DC gas-discharge and has flat discharge display elements, which elements have three electrodes composed of a cathode, a grid and an anode and a discharge stabilizing resistor. An auxiliary discharge is formed by using the discharge stabilizing resistor, the cathode and the grid in an auxiliary discharge space defined between the grid and the cathode. A main gas discharge is formed in a main discharge space defined between the anode and the grid by mainly using electrons in a plasma, produced in the auxiliary discharge space, which are diffused and accelerated into the main discharge space. The flat discharge panel, in order to provide a memory function in the main discharge is driven by the use of pulse voltage applied between the anode and the grid.

摘要： A system for driving a display device having photo elements driven by pulsed current from pulsed current sources in which the firing voltage or operating voltage of the photo elements differs from the extinction voltage thereof. The system includes apparatus for setting the voltage applied to the photo elements to a value less than the extinction voltage at a time near the trailing edge of the pulsed current.
