Description
Im Patent 950 873 ist eine Vakuumröhre zur Messung und Anzeige elektrischer Spannungen, bei der auf einem Leuchtschirm ein Leuchtsektor erzeugt wird, dessen Größe ein Maß für die Spannung ist, und bei der eine einzige Leuchtkante über d-en Leuchtschirm bewegt wird, beschrieben. Ferner sieht das Hauptpatent Anordnungen vor, bei denen die zur Steuerung des Anzeigesystems verwendeten Verstärkersysteme innerhalb des Kolbens untergebracht sind.In patent 950 873 a vacuum tube for measuring and displaying electrical voltages is at which creates a luminous sector on a luminescent screen, the size of which is a measure of the voltage and in which a single luminous edge is moved over the luminescent screen. Further the main patent provides arrangements in which those used to control the display system Booster systems are housed within the piston.
Eine besonders einfache und günstige Anordnung des Anzeige- und Verstärkersystems wird nach vorliegender Erfindung dadurch erreicht, daß man das Verstärkersystem neben der Ablenkelektrode so anordnet, daß die Ablenkelektrode des Anzeigesystems gleichzeitig als Anode des Verstärkersystems dient. Durch diese Anordnung wird eine besonders leichte und billige Aufbauweise erzielt. Bei Verwendung direkt geheizter Kathoden hat man bei der vorgeschlagenen Anordnung noch den weiteren Vorteil, daß die beiden Teile der Kathode sich in unmittelbarer Nachbarschaft befinden. An Hand des Ausführungsbeispieles der Zeichnung sei die Erfindung näher beschrieben.A particularly simple and cheap arrangement of the display and amplifier system is according to The present invention achieved that the amplifier system next to the deflection electrode so arranges that the deflection electrode of the display system also acts as the anode of the amplifier system serves. A particularly light and inexpensive construction is achieved by this arrangement. If directly heated cathodes are used, the proposed arrangement still has the Another advantage that the two parts of the cathode are in the immediate vicinity. At The invention will be described in more detail using the exemplary embodiment of the drawing.
In der Zeichnung ist mit 1 die Kathode des Anzeigesystems, die von dem Gitter 2 umgeben ist, bezeichnet. Zwischen den Elektroden 3 und 4 bildet sich das Ablenkfeld aus. Die Ablenkelektrode 3 ist gleichzeitig Anode des Verstärkersystems mit der Kathode S und dem Gitter 6. Die Anode 3 kann vollständig geschlossen sein. Diese beschriebene Anordnung hat den großen Vorteil, daß die zwei Kathoden 1 und S sehr nahe benachbart sind und daß sie durch einen gemeinsamen Heizer, der teilweise in der Kathode 1 und teilweise in der Kathode 5 angeordnet ist, betrieben werden kann. Die Anordnung hat weiterhin den Vorteil, daß die Ablenkelektrode 3 eine höhere Temperatur annimmt, als dies in üblichen Spannungsanzeigeröhren der Fall ist. Durch die höhere Ablenkelektrodentemperatur erhält man eine wesentlich gleichmäßigere Sekundärelektronenemission dieser Elektrode, wodurch Schwankungen des Ablenkelektrodenstromes kleiner werden, als wenn diese Elektrode kalt betrieben würde.In the drawing, 1 is the cathode of the display system, which is surrounded by the grid 2, designated. The deflection field is formed between the electrodes 3 and 4. The deflection electrode 3 is at the same time the anode of the amplifier system with the cathode S and the grid 6. Die Anode 3 can be completely closed. This arrangement described has the great advantage that the two cathodes 1 and S are very closely adjacent and that they are shared by one Heater, which is arranged partly in the cathode 1 and partly in the cathode 5, operated can be. The arrangement also has the advantage that the deflection electrode 3 is higher Temperature than is the case in conventional voltage indicator tubes. By the higher Deflection electrode temperature, a significantly more uniform secondary electron emission is obtained this electrode, whereby fluctuations in the deflection electrode current are smaller than when this electrode would be operated cold.
