Abstract: A current protector comprising an organic resin-made insulating substrate, a pair of terminals formed at both ends of the insulating substrate, and an electrical conductor electrically connecting the terminals and having a thickness of 3-8 .mu.m and formed in or on the insulating substrate, is excellent in suppressing ignition and smoking at the time of blowing, and can be improved in clearing characteristics by various modifications.

Abstract: An anode assembly of a magnetron includes an anode cylinder and a plurality of anode vanes arranged in the cylinder. The cylinder has a plurality of projections protruding from the inner surface thereof. A connecting end portion of each vane is engaged with the inner surface of the cylinder and located between the corresponding projections. The connecting end portion is mechanically fixed to the inner surface of the cylinder by caulking the projections, and electrically connected to the cylinder by soldering. In manufacturing of the assembly, the vanes are fixed to the cylinder by caulking the projections while they are positioned with respect to the cylinder by a positioning jig. Then, the vanes and cylinder are soldered to each other after removing the positioning jig from the assembly.

Abstract: A magnetron comprises a ceramic stem having a cathode support structure. Sealing metal plates are sealed hermetically to the cathode side of the ceramic stem, closing off hermetically the holes running through the stem for the outer connecting leads. The outer connecting leads are connected electrically to the sealing metal plates. The cathode, which is disposed in the center of the anode, is supported by a pair of cathode support rods. The cathode support rods are fixed to the sealing metal plates. In another embodiment, the end-face of the ceramic stem is formed such that the part of the surface of the stem to which the cylindrical metal container, which constitutes part of the envelope of the stem, is sealed by brazing, and those parts of the surface to which the sealing metal plates are sealed by brazing, are positioned substantially on the same plane.
