摘要： Provided is a low-cost magnetron that is excellent in productivity without any adverse effect on characteristics.Two large and small strap rings 11 (11A and 11B) are only disposed at lower ends, or input sides, of a plurality of vanes 10 (10A and 10B) in the direction of a tube axis m. Diameter Rip of a protruding flat surface 41 of an input side pole piece 18 is larger than diameter Rop of a protruding flat surface 40 of an output side pole piece 17. Therefore, it is possible to provide a practical magnetron without a significant decrease in productivity or characteristics from a conventional one, while cutting costs by reducing the number of parts with the use of two strap rings on one side.

摘要： A magnetron for microwave ovens includes an anode cylinder, a plurality of plate-shaped vanes radially arranged along an inside surface of the anode cylinder, one or more strap rings to electrically connect the plurality of plate-shaped vanes to each other, an antenna connected to one of the plurality of vanes to radiate microwaves generated from the plurality of vanes. Each of the vanes is plated with a brazing material to be brazed to one or more of the anode cylinder, the one or more strap rings and the antenna, and the brazing material has a plating depth of about 2.25 to 8 μm. The magnetron having the anode allows a manufacturing process of the anode to be simplified to reduce manufacturing time and equipment costs. Furthermore, the anode prevents brazing defects, and allows the magnetron to have an optimal performance.

摘要： An actuator for rotation of coupling means such as a loop in a high frequency resonant cavity includes a rotatable member to which the loop is fixed and a rod located adjacent it. The member and rod have interengaging teeth such that when the rod is moved inwardly or outwardly by an operator it causes the member, and hence the loop, to rotate. This is a compact assembly having components which are simple and easy to facilitate. In a preferred embodiment, the rod is located in a groove in the cavity wall.

摘要： A microwave magnetron-type device comprises at least one anode block with annular metal straps electrically associated with respective vanes of the anode block cavities, having the same polarity at -mode. The straps of different polarities, electrically associating respective vanes of the same polarity, are paired, each pair being arranged with respect to one another along the anode block axis to form a single multistage retardation system. The device also comprises a means for creating a magnetic field directed along the anode block axis enveloping said anode block, and a means for increasing the magnetic field density in direct proximity to the anode block end faces, forming a gap with the end faces of the anode block. At least some of said straps are made at least partically of a magnetic material, and the mass of this material is so distributed along the anode block axis that the magnetic field density varies along the anode block axis as follows: ##EQU1## where B.sub.x is the variation in the magnetic field density along the anode block axis;B.sub.O is a constant component of the homogeneous magnetic field density along the anode block axis;B.sub.O1 is the amplitude of variation in the magnetic field density along the anode block axis, over its length X.sub.1, which does not exceed 50% of B.sub.O ;B.sub.O2 is the amplitude of fluctuation of the magnetic field density from one pair of retardation system straps to another along the anode block axis, over its length X.sub.1, which does not exceed 20% of B.sub.O ;h is the spacing between strap pairs;n=1,2,3 . . . is a coefficient equal to the number of half-cycles of the cosinusoidal distribution of the amplitude of the high-frequency electric field of a respective mode.
