    Abstract: Ein direktgeheizte Kathode mit Heizungsregelung in Elektronenstrahlgeräten soll über lange Zeiträume hinweg eine stabilisierte Temperatur(T) aufweisen. Erfindungsge mäß weist eine direktgeheizte Kathode Mittel (RS) zur Leistungsregelung der Kathodenheizung mit Hilfe von Mit teln (MV) zur Steuerung des Heizstromes (I) und der Heizspannung (U) auf. Erfindungsgemäß wird eine direktge heizte Kathode so betrieben, daß ihre Kathodentemperatur konstant ist.

    Abstract: 비디오 디스플레이 튜브용 전원은 제1 비디오 표준에 따른 신호를 디스플레이 할때 제1 값을 갖고, 제2 표준에 따른 비디오를 디스플레이할 때 제2 값을 갖는 스캔 전압으로 전원이 공급된 주 권선을 갖는 편향 트랜스포머를 포함한다. 트랜스포머의 제2 권선은 디스플레이 튜브용의 필라멘트 전압을 생성한다. 다양한 접속기는 필라멘트 전압을 제어 신호에 의해 설정된 양의 화상 튜브의 필라멘트에 접속한다. 메모리는 제1 스캔 전압에 응답하여 제1 제어 신호를, 제2 스캔 전압에 응답하여 제2 제어신호를 생성한다. 제1 및 제2 제어 신호들은 선택되어 트랜스포머으로부터 필라멘트로 접속된 전압이 양자의 스캔 전압에서 동일하도록 한다.

    Abstract: PROBLEM TO BE SOLVED: To provide a filament assembly for use in an X-ray emitting device or other filament-containing devices.
    SOLUTION: An X-ray tube includes a vacuum enclosure that houses both a positive electrode having a target surface, and a negative electrode positioned with respect to the positive electrode. The negative electrode includes the filament assembly for emitting a beam of electrons during tube operation. The filament assembly comprises a heat sink and a plurality of filament segments. The plurality of filament segments are configured to simultaneously emit electron beams to be impinged on the target surface of the positive electrode, and are electrically connected in series. Each filament segment includes first and second end portions that are thermally connected to the heat sink, and a central portion having its work function modified to preferentially emit electrons.

    Abstract: A vacuum tube optimization circuit can automatically ensuring that the preheating required for the thermionic effect to occur within the vacuum tubes within a vacuum tube device, has been sufficient to allow the vacuum tubes to reach their operating temperatures, before allowing signal voltage or current to be applied to their anodes, cathodes, and/or other thermionically-active components. This reduces the diffusion of component-specific surface material coatings onto the surfaces of other internal elements within the vacuum tube, functioning to extend the service life of the vacuum tubes.
