Abstract: A cathode substrate 10 is heated to 400 to 600 °C in the atmosphere of hydrocarbon gas such as methane and the gas is allowed to react with the surface of the cathode substrate 10 by a thermal CVD method. Thus, an electron emission source in which graphite nano-fibers 11 are allowed to grow in a gaseous-phase on the surface of the cathode substrate 10 by using nickel or iron existing on the surface of the cathode substrate 10 as a nucleus is held between upper and lower end hats 12 to form a cathode part 13.

Abstract: A magnetron arrangement has a coaxial output (13) including a central conductor (14). The output further comprises a plate (19) located in a predetermined position with respect to the central conductor. The plate optimises the coupling of energy between the magnetron (11) and a rectangular waveguide (17). Previously, the central conductor of the coaxial output was arranged in a predetermined position with respect to a wall of the waveguide, but it was found that the amount of coupling thus produced was dependent on the type of end flange fused at the end of the waveguide.

Abstract: A magnetron for a microwave oven includes a yoke (20), an anode cylindrical body (30) installed inside the yoke (20), a plurality of vanes (40) mounted inside the anode cylindrical body (30), a filament (50) installed in a center of the vanes, and an upper magnet (60a) and a lower magnet (60b) respectively mounted on an upper side and a lower side of the anode cylindrical body (30). The magnetron also includes an upper pole piece (70a) and a lower pole piece (70b) respectively installed between the anode cylindrical body (30) and the upper and lower magnets (60a,60b). A length (L) from an external tip of a central part (74) of the upper pole piece (70a) to an internal tip thereof, on which a hollow part (73) is formed, is adjusted to suppress harmonics in the magnetron. Thus, generation of the harmonics may be effectively attenuated, and an output of a microwave may be enhanced by preventing power consumption of the magnetron which may be large due to interrupting harmonics.

Abstract: A magnetron for use in, for example, microwave ovens, includes a positive polar cylinder (101), a plurality of vanes (102), and large-diameter and small-diameter strip rings (401,402). The vanes (102) constitute a positive polar section, along with the positive polar cylinder (101). The large-diameter and small-diameter strip rings (401,402) are disposed on an upper portion and a lower portion of the vanes, respectively, to alternatively and electrically connect the vanes to one another. The inside and outside diameters of the large-diameter strip ring (401) are in a range of 17.1 mm to 18.01 mm and 18.6 mm to 19.6 mm, respectively. The inside and outside diameters of the small-diameter strip ring (402) are in a range of 13.4 mm to 14.4 mm and 14.9 mm to 15.9 mm, respectively. The height of the large-diameter and small-diameter strip rings (401,402) is in a range of 1.50 mm to 1.60 mm. The distance between the large-diameter strip ring and the small-diameter strip ring is maintained in an error range of 2.20 mm. Advantageously, the magnetron is readily manufactured having a desired frequency, and a high efficiency (Q).

Abstract: A crossed-field device, such as a crossed-field amplifier, includes a cathode body portion (14) and an anode body portion (16) which cooperate with a crossed magnetic field to maintain electrons in a cycloidal path and to amplify an input signal through the interaction between the electrons and the signal within an interaction space or gap (15). Ceramic grooved windows (25, 26) cover the input and output transformer bodies (50, 51) of the device and provide for reduced secondary emission yield. Additionally, one or more walls of the device are physically structured or chemically treated for further reduction of multipactoring effects. For example, a thin layer of molybdenum oxide may be coated on the anode (16) and/or on the cathode (14) to sustain such multipactoring reduction. Alternatively, one or more of the walls of the device may be grooved for reduced multipactoring operation. The device operates in a switch mode which shuts down between working cycles.
