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.

摘要： A capacitor has electrodes at surfaces thereof, with one of the electrodes secured onto one surface of a grounding metal. Through conductors pass through the capacitor and the grounding metal and are connected to the other electrodes so as to achieve electrical continuity. An insulating case is provided at one surface of the grounding metal, with one end of the insulating case fitted around the external circumference of the raised portion of the grounding metal. Insulating resin fills a space inside the insulating case, the internal space of the grounding metal and a space around the capacitor. The insulating resin comprises an epoxy resin containing a brominated fire retardant, and the brominated fire retardant is a brominated aromatic glycidyl ether.

摘要： A noise shielding apparatus for the magnetron of a microwave oven for preventing the lowering of the voltage resistance of the capacitor due to the poor concentricity and the poor interfacial state is disclosed. A shielding case has a side wall with an elliptic opening and a projected portion along the elliptic opening by bending out a circumference portion thereof. The capacitor includes an elliptic cylindrical ceramic dielectric, separate electrodes separately formed on an upper surface of the ceramic dielectric and a common electrode formed on a lower surface of the ceramic dielectric. Through conductors pass through the through holes and are connected to a choke coil of the magnetron. Each of through conductors is provided with an electrode connection portion for electrically connecting with the separate electrodes integrally and horizontally formed from around an upper portion of each of through conductors. An insulation lattice is formed at a central upper portion of the insulation case over a border line of the separate electrodes. Forming the electrode connection portion prevents the poor perpendicularity and/or poor interfacial state. Providing the insulation lattice solves simply and stably the insulation problem between fastening tabs and thus the magnetron may be stably operated.
