    摘要： An electron tube provided with a semiconductor cathode for emitting electrons, which semiconductor cathode is arranged on a support, a source being arranged in the vicinity of the cathode, in particular, so as to face the free (Si) surface of the cathode, which source is capable of evolving, at the increased temperatures occurring during evacuation of the tube in the manufacturing process, a reducing agent such as F2 or HF, which passivates the free (Si) surface of the cathode.

    摘要： A semiconductor cathode (11) in a semiconductor structure, in which the sturdiness of the cathode is increased by covering the emitting surface (4) with a layer of a semiconductor material (7) having a larger bandgap than the semiconductor material of the semiconductor cathode. Various measures for increasing the electron-mission efficiency are indicated.

    摘要： In an electron tube based on a cold cathode, a cesium source (17) containing Csx—Auy or Csx—Sby is provided near the cold cathode (7), preferably in contact with the first grid (9). Cesium is introduced into the source during activation of the tube. The vapor pressure of the cesium compounds is such that proper delivery of cesium is guaranteed throughout the life-time of the cathode.

    摘要： The invention relates to an electrical stimulation device (10) and to a method of locating an electrical stimulation point (132s, 138s) of a human or animal. The electrical stimulation device comprises:—a matrix of electrodes (120 . . . 140) distributed on an electrode pad (20) being configured to be applied on the human or animal body, the distribution of the electrodes in the matrix being arranged for covering a plurality of the stimulation points of the human or animal,—an electronic circuit (30) being connected to the electrodes of the matrix, and being configured for applying an electrical stimulation signal (TS, PSS, FES) to the electrodes of the matrix, and—feedback means (20, 40, 42) for providing a feedback signal (FS1, FS2, FS3) to the electrical stimulation device in response to the applied electrical stimulation signal. The electrical stimulation device being configured for sequentially applying the electrical stimulation signal to subsets of electrodes of the matrix, and for receiving the feedback signal in response to the applying of the electrical stimulation signal to the subsets of electrodes. The effect of the electrical stimulation device is that the electrical stimulation signal generates some kind of feedback signal which is used in assessing the suitability of the subset of electrodes as an electrical stimulation point of the human or animal. By sequentially applying the electrical stimulation signal to the subsets of electrodes, the suitability of the electrodes of the matrix of electrodes as electrical stimulation point is tested by the electrical stimulation device.
