Description
Es ist fernerhin bekannt, bei einer Oszillagraphenrähre mit der Elektrodenfolge Glühkathode, Anode, Ablenkplatten und Fluoreszenzschirm diesen als Hilfselektrode auszubilden und so anzuordnen, daß er in Aufsicht beobachtet bzw. abgebildet werden kann.It is also known, in the case of an oscillating graph tube with the electrode sequence Hot cathode, anode, deflector plates and fluorescent screen use these as an auxiliary electrode to be trained and to be arranged in such a way that it can be observed or depicted in supervision can.
Gegenstand der Erfindung ist eine Hochvakuumelektronenröhre zur photographischen Tonaufzeichnung, bei der unter Verwendung einer aus Kathode, Steuergitter und spaltförmiger Anode bestehenden trägheitslosen elektrischen Vorrichtung :ein als Hilfselektrode ausgebildeter, in großem Abstand von den übrigen Elektroden angeordneter und unter einer Vorspannung stehender stabförmiger Fluoreszenzschirm benutzt wird, bei dem das Verhältnis von Länge und Durchmesser den in der Tonfilmtechnik gebräuchlichen Spaltnormali;en -entspricht.The invention relates to a high vacuum electron tube for photographic use Sound recording made using a cathode, control grid and slit-shaped Anode existing inertia-less electrical device: one as an auxiliary electrode trained, arranged at a large distance from the other electrodes and below a bias standing rod-shaped fluorescent screen is used, in which the ratio of length and diameter is the one used in sound film technology Gap normals correspond to.
Eine solche -stabförmige Leuchtelektrode ist für Tonfilmzwecke besonders zweckmäßig, da sie bei. einfacher Herstellungsweise definierte Begrenzungskanten besitzt und andererseits nur solche Elektronen auffängt, die tatsächlich zur Lichterregung ausgenutzt werden. Schließlich ist ein in vorliegendem Falle als Stab ausgebildeter undurchsichtiger Fluoreszenzschirm in der Lichtausbeute einem durchsichtigen Fluoreszenzschirm überlegen.Such a rod-shaped luminous electrode is particularly useful for sound film purposes functional as they are at. delimiting edges defined in a simple manner of manufacture and on the other hand only collects those electrons that actually cause light to be excited be exploited. Finally, in the present case, one is designed as a rod opaque fluorescent screen in the light output of a transparent fluorescent screen think.
Die Erfindung wird an einem Ausführungsbeispiel beschrieben. Die Abbildung zeigt schematisch eine Anordnung, bestehend aus der Kathode I(, dem Steuergitter St, der durchbrochenen Anode A und der stabförmigen Leuchtelektrode L, die mittels einer Optik auf einem Film abgebildet wird.The invention is described using an exemplary embodiment. The illustration shows schematically an arrangement consisting of the cathode I (, the control grid St, the perforated anode A and the rod-shaped luminous electrode L, which means an optic is imaged on a film.
Wie aus der Abbildung ersichtlich, ist das Steuergitter als Platte ausgebildet und, in entgegengesetzter Elektronenflugrichtung gesehen, hinter der Kathode angebracht, und zwar derart, daß sie die Glühkathode lichtabschirmend umgibt.As can be seen from the figure, the control grid is a plate formed and, seen in the opposite electron flight direction, behind the Cathode attached, in such a way that it surrounds the hot cathode in a light-shielding manner.
