Certain aspects are directed to an RF thermal fuse comprising: a body adapted to be positioned on a transmission line between an RF signal source and an RF device; a conductive bolt positioned in the body, the conductive bolt adapted for reflecting a portion of a signal power of an RF signal from the RF signal source when the conductive bolt is in contact with a live conductor of the transmission line; and a driving mechanism configured to cause the conductive bolt to contact the live conductor in response to a temperature at a measurement point collocated with the transmission line exceeding a threshold temperature.

Es wird eine Gehäusevorrichtung (120, 502) beschrieben, die einen Hohlleiter (501, 102) aufweist, der für die Führung einer elektromagnetischen Welle mit einer vorgebbaren Wellenlänge ausgebildet ist und eine zu der Ausbreitungsrichtung einer von dem Hohlleiter geführten elektromagnetischen Welle im Wesentlichen senkrecht verlaufende Randfläche (131, 603) aufweist, wobei die Gehäusevorrichtung sowohl eine Wandeinrichtung (101, 606) als auch eine Schutzvorrichtung (100, 508) mit einer Auflagerfläche aufweist. Die Wandeinrichtung hält die Schutzvorrichtung an einem Ende des Hohlleiters durch eine Presskraft.
摘要:
A cavity filter has a resonator. The resonator is engaged by a rod having a mounting portion and a thermal dissipation portion. The mounting portion of the rod extends through the floor of the cavity filter to engage an internal surface of the resonator. The thermal dissipation portion dissipates heat from the resonator to the outside of the cavity filter.

Apparatus for preventing energy leakage from a transmission line treats the line as a "partially closed" vessel. A gas stream with a pressure slightly different from ambient pressure is provided to the interior of the transmission line and a conduit that allows gas to pass between the transmission line and the ambient environment is provided. The gas flow rate at the conduit is then detected and monitored. If the flow rate falls outside a predetermined threshold, an electrical energy leakage is indicated. In another embodiment, the pressure of the input gas to the transmission line is continuously checked by a pressure switch, which will detect a change in pressure if the transmission integrity is compromised and disable the energy source.

The present invention relates to a heat insulating type coaxial cable. According to the arrangement of a superconductive filter (1), a columnar resonating member (23) having a superconductive material formed on the surface thereof is attached at one of its ends thereof to an inner wall (22) of a filter housing (21) so that a space is interposed between the columnar resonating member and each of connectors (27a,27b) which are connectable to a signal input/output cables (5a,5b), respectively. According to this arrangement, heat conduction from the outside can be suppressed as far as possible by means of an interdigital capacitive interruption in the external conductor of a coaxial cable, connectable with the filters, and the superconductive condition can be created with stability, with the result that a stable filtering characteristic can be created. Further, the superconductive filter will become excellent in power withstand performance, and hence even if the number of stages of filters is increased for attaining a steep cutoff characteristic, the loss deriving from the increased number of stages can be suppressed to the minimum level.
