    摘要: An optronic observation device including a detector having a photocathode and a sensor arranged to receive an incident light beam. The device also including a switch to position an optical element opposite the detector in the pathway of the incident beam or to retract the optical element and a focusing element to focus an incident ray on the photocathode when the optical element is in a retracted position. When the optical element is positioned opposite the detector, it is able to focus the beam on the sensor and to filter the beam spectrally to block all or part of the wavelengths for which the responsiveness of the photocathode is greater than a given threshold.

    摘要: A socket assembly for a CRT includes a socket mounted on a printed circuit board having a plurality of spark gaps interposed between an open grounding ring and the terminals of the socket. The spark gaps associated with the cathode and heater socket terminals have larger width dimensions than those associated with the other electrode terminals and are positioned adjacent to the portion of the open grounding ring farthest from the connection to the CRT "dag".

    摘要: A radio-frequency amplifier includes at least two double-ended electron discharge devices in coaxial-type, radio-frequency cavity-resonator circuits. Each discharge device has a discharge region so that the amplifier comprises a plurality of longitudinally spaced-apart, electrically connected discharge regions. Each of the discharge regions has a cathode with an anode circumscribing the cathode. At least one grid electrode is disposed between the cathode and the anode. A coaxial input transmission line is loop-coupled to an input cavity-resonator circuit and a coaxial output transmission line is loop-coupled to an output cavity-resonator circuit.

    摘要: A electron-beam tube comprises a cathode (2) made as individual tapes (6) disposed throughout the length of the tube, whose surfaces are the emitting portions of the cathode (2). Each tape (6) of the cathode (2) is provided with a near-cathode focusing electrode (9) electrically connected to the cathode (2) and disposed in the immediate vicinity of the tape (6), and with a pair of rods (10) of the control electrode (3) disposed in relation to the tape (6) so that the whole electron flow focused by the near-cathode electrode (9) passes between said rods (10). The following relations are observed in the tube:a/b=c/d; 1
