摘要： Dieser Resonator weist zwei einander gegenüberliegende Hohlspiegel (1, 2) mit annähernd sphärischer Krümmung auf. Zur Begünstigung der Ausbildung einer einzelnen, gewünschten TEM oop -Mode gegenüber TEM ooq -Moden mit q = p ±1, p ±2, ..., im Resonator, sind die Hohlspiegel (1, 2) jeweils mit mindestens zwei um ein oder mehrere ganze Vielfache der halben Wellenlänge λ p /2 der gewünschten TEM oop -Mode stufenförmig gegeneinander versetzten Spiegelflächen (1.1, 1.2 bzw. 2.1, 2.2) versehen.

摘要： The invention relates to a tunable magnetron comprising a rotatable tuning element (10) projecting into a ring shaped interaction space between coaxially arranged cathode and anode systems. The tuning element (10) is driven by an electric motor (11) and produces upon rotation a periodic variation of the tuning. The tuning element (10) is situated within the evacuated space of the magnetron and the motor - (11) in situated outside said space. The drive torque of the motor is then transferred to the tuning element via a coupling (12) having two active parts situated one on each side of the evacuated envelope (17) of the magnetron. Such a coupling can only transfer a limited torque. According to the invention the magnetron comprises means for limiting the torque which can be transferred to the coupling (12), both upon starting and stopping, for example a torque limiter (21-26) between the motor (11) and the coupling (12), whereby the start and stop procedures can be performed with optimum torque. Therefore starting and stopping of the tuning element (10), for example when switching between different fixed frequencies, can be made with maximum speed (fig.3).

摘要： Provided is a klystron device with improved output conversion efficiency. The klystron device includes a klystron body and a focusing magnetic field device. The klystron body includes an electron gun part, a collector part, multiple cavity resonators, and multiple drift tubes. The cavity resonators each have nose sections that are opposed to each other in the axial direction and form a gap section communicating with a drift tube. At least one of the cavity resonators has, in portions of the nose sections, electric-field correction sections that make the interval in the gap section different from the interval between the nose sections.

摘要： There are provided a microwave tube that can contribute to keeping the high frequency output of the microwave tube constant for a long period of time without complex structure or adjustment and a method for controlling the same. The microwave tube comprises an electron gun that emits an electron beam; a magnetic circuit that focuses the electron beam emitted from the electron gun; a collector that captures the electron beam that has passed through the magnetic circuit; a high frequency circuit that is spirally arranged around the electron beam focused by the magnetic circuit and that transmits a high frequency; and a magnetic body part arranged around the electron gun so as to be movable in an emission direction of the electron beam, wherein a high frequency output from the high frequency circuit is controlled to be constant by moving the magnetic body part in an emission direction of the electron beam.

摘要： To provide a magnetron capable of suppressing generation of a reactive current and noise thereby improving oscillation efficiency, and a device using microwaves which includes the magnetron. A magnetron of the present invention includes: an anode cylinder including a plurality of anode vanes provided at a predetermined interval on an inner peripheral surface thereof; a center lead including a first linear portion, a second linear portion which is disposed parallel to the first linear portion and which is disposed out of alignment with the first linear portion in a plane perpendicular to an axial direction of the anode cylinder, and a bent portion which connects the first linear portion to the second linear portion; and a cathode filament which is supported by the center lead within the anode cylinder and which is placed coaxially with the anode cylinder. The center lead is formed so as to become bent between the first linear portion and the second linear portion by the bent portion. A position of one anode vane closest to the bent portion is higher than a position of another anode vane with respect to the axial direction of the anode cylinder.

摘要： A magnetron for microwave ovens includes an anode cylinder (10), a plurality of plate-shaped vanes (20) radially arranged along an inside surface of the anode cylinder (10), one or more strap rings (30) to electrically connect the plurality of plate-shaped vanes (20) to each other, an antenna (140) connected to one of the plurality of vanes (20) to radiate microwaves generated from the plurality of vanes (20). Each of the vanes (20) is plated with a brazing material to be brazed to one or more of the anode cylinder (10), the one or more strap rings (30) and the antenna (140), 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.
