摘要： An inductive filter for a magnetron power supply lead comprises an electrically insulating tube; a power lead located partially within the electrically insulating tube, and coaxial therewith, for supplying power from a magnetron power supply to a magnetron, a first core of a first magnetic material and a second core of a second magnetic material coaxially located on the electrically insulating tube; an insulating disc of same external diameter as the first core and the second core and coaxially located on the electrically insulating tube between the first core and the second core. The inductive filter is arranged to filter noise of a first frequency band and noise of a second, different, frequency band different from being transmitted along the power lead and to absorb a predetermined transient voltage from being transmitted along the power lead.

摘要： A magnetron for microwave ovens including a second insulator interposed between a connection part and a bottom of a yoke to form a relatively lengthened insulation distance, or a molded insulating plate attached to a bottom of the filter box to reduce a distance between the connection part and a bottom of the filter box. In the magnetron, an entire height of the magnetron is reduced, so that a miniaturization of the magnetron can be implemented and a design of a product including the magnetron, such as a microwave oven, can be freely carried out, thus allowing an appearance of the product to be variously designed.

摘要： A high frequency electromagnetic energy absorber disposed near a cathode holder in an evacuated envelope of a magnetron so as to attenuate high frequency noise leaking through the cathode terminal of the magnetron. The absorber is in thermal contact with a member connected to the anode cylinder of the tube to conduct heat generated in the tube, whereby overheating of the tube can be prevented. By combining the absorber with another high frequency attenuating element, the attenuating effect can be increased.

摘要： A microwave electron beam tube having a high-frequency interaction section insulated from the collector section of the tube by a gap across which the electron beam passes, the collector being surrounded by water contained in a boiler. The gap is shunted by a capacitor of solid material with its electrodes outside the evacuated envelope of the tube. The boiler is mechanically and electrically connected to a metal flange and a further flange is electrically and mechanically connected to the collector. Inserted between the two flanges is a dielectric spacer which offers a high impedance to what would otherwise be large high-frequency current flowing between the two flanges thus reducing radiation from the boiler to a negligible level.
