    摘要: In an inner magnet type magnetron wherein a pair of permanent magnets axially magnetized are opposed to each other with an interaction space therebetween within a vacuum enclosure comprising a cylindrical anode, a repulsive magnet magnetized in a direction substantially perpendicular to the magnetization direction of the permanent magnet is arranged in the proximity of one end of the permanent magnet close to the interaction space, thereby preventing leakage flux from the permanent magnet to the inner wall of the cylindrical anode.

    摘要: A cathode structure of a magnetron which is used for microwave ovens, industrial microwave heating, and medical purposes is disclosed. One of two leads of the cathode structure of the magnetron, that is, one of a center lead and a side lead is tightly fitted into the spacer, and a metal fixing material is poured into the fitting portion and is fixed thereto. A hole of the spacer for inserting the other of the two leads has looseness with respect to the other of the two leads. The friction between the other of the two leads and the spacer is reduced, and even when the leads are made thin, the strength of the cathode structure is not reduced, and the production of extraneous sounds can be suppressed.

    摘要: At least one permanent magnet and a pole piece having a projection is contained in an evacuated envelope formed by an anode cylinder and yokes on the opposite ends thereof. The permanent magnet and the pole piece is clamped between one yoke and a holder secured to the inner wall of the anode cylinder. The holder is provided with an opening a little smaller than the outer diameter of the projection and the projection is force-fitted into the opening to project into an interaction space defined between anode vanes and the cathode electrode.

    摘要: A magnetron having an anode cylinder, cooling fins fixed thereto, permanent magnets vertically superposed on the anode cylinder and a yoke, serving as a magnetic path, for surrounding these components. The cooling fins extend on the windward direction to facilitate a discharge of the air in the orthogonal direction to the air blowing direction by an arrangement such that an outer width of the fins and a width of the yoke or the former is equalized to a diameter of the anode cylinder. Also included are a dielectric heater having a heating space for accommodating materials for heating and a space for accommodating the magnetron, an inverter power supply and a cooling air blower. The cooling air is discharged to the heating space and/or to the outside via a vent hole formed in a partition wall after impinging on the anode cylinder while cooling the fins.

    摘要: A cathode structure for a magnetron representative of a self-oscillation type microwave electron tube comprises a pair of opposite end shields for supporting both ends of a filament helically wound in an axial direction, and a getter fixed on at least an upper end shield positioned on the side of a terminal from which a microwave oscillation output is produced. The upper end shield is concaved with respect to a lower end shield, and the getter provided on the upper end shield is also concaved so as to be closely fitted over substantially the entirety of an outer surface of the upper end shield. Preferably, the getter provided on the upper end shield has an upright annular wall of a central burring hole. Thus, the improved cathode structure is immune to deformation and suitable for cleaning and welding, thereby ensuring improved lifetime stability and high fabrication efficiency.
