摘要： An electron emissive material of the formula (Y.sub.1.sub.-x EU.sub.x)B.sub.6 having the calcium hexaboride type crystal structure can easily produce hexaborides of the single phase. These borides have a number of merits such as small work function, high mechanical properties and low vapor pressure, and they are far more excellent than prior-art materials when used in a thermionic emission cathode and a field emission type cold cathode.

摘要： An electron tube cathode has a composite suppression layer structure interposed between the base metal and the electron-emitting material to suppress an interface layer formed through the reaction of the base metal with the electron emissive material. The composite layer structure includes a thin layer of Pt or Re and a layer of oxide of Zr and/or Hf. As a result, the formation of the interface layer is prevented so that the useful life of the electron tube cathode is prolonged.

摘要： A pair of superconducting electrodes are so formed as to interpose a semiconductor therebetween, and a control electrode is formed on the semiconductor through an insulator film so as to control the superconductive weak coupling state in the semiconductor between the superconducting electrodes. The distance between the superconducting electrodes is determined by the thickness of the superconductor interposed between the two electrodes, whereby the interelectrode distance is settled with a high precision to improve the uniformity of the device characteristic.And in an arrangement where two superconducting electrodes are formed on a semiconductor layer and the superconductive weak coupling state between such two electrodes is controlled by a third electrode, the gain is increadable by furnishing a varied impurity distribution in the semiconductor layer.
