摘要: In an exemplary embodiment, a metal capillary cathode for electric discharge vessels with an emission substance carrier disk porous on its front face and comprised of metal melting at a high temperature is constructed to prevent lateral emission of electrons (interfering emission). To this end, the disclosure provides that the emission substance carrier disk has a nonporous outer casing surface with a higher electron work function than the outer, active surface of the emission substance carrier disk. Such a dispenser cathode is employed as a metal capillary cathode in traveling wave tubes.

摘要: A watch, and more particularly a wristwatch is disclosed in which the hours are only displayed in an analog manner and the minutes are only displayed in a digital manner. In the suggested display concept, the time of day is not illustrated in multiple fashion, but rather in a partially analog and partially digital manner. An analog hour display immediately provides a first overview completely sufficing in many cases, whereas a precise display for minutes and, if necessary, for seconds in digital form supplements the feeling for time provided by the hour display with effortless precision. The analog display is advantageously formed by chronologically, consecutively actuated, luminescence elements normally grouped in the shape of a wreath ("quasi-analog display").
