    摘要： A gyrotron system comprises an electron gun that produces an electron beam, a magnetic field generating unit comprising a permanent magnet and two electromagnets and capable of generating an axial magnetic field that drives electrons emitted from the electron gun for revolving motion, a cavity resonator that causes cyclotron resonance maser interaction between the revolving electrons and a high-frequency electromagnetic field resonating in a natural mode, a collector for collecting the electron beam traveled through the cavity resonator, and an output window through which a high-frequency wave produced by the cyclotron resonance maser interaction propagates. The gyrotron system can be fabricated at a comparatively low cost, is easy to operate, has a comparatively small size and is capable of operating at a comparatively low running cost.

    摘要： The invention provides a cylindrical permanent magnet unit suitable for application to gyrotrons. Essentially the magnet unit consists of two cylindrical permanent magnets which are coaxially aligned, and there is a space between the two cylindrical magnets. Each of the two cylindrical magnet is a coaxially juxtaposed assembly of a plurality of ring-like permanent magnets, and each ring-like magnet is constructed of a plurality of permanent magnet segments. In one of the two cylindrical magnets every ring-like permanent magnet is magnetized in radial directions from the inside toward the outside, and in the other every ring-like permanent magnet is magnetized in radial directions from the outside toward the inside. In the bore of the cylindrical magnet unit the magnetic field is in the direction of the longitudinal center axis of the bore. By virtue of the space between the two cylindrical magnets, the distribution of flux density in the direction of the center axis becomes flat in a middle section of the bore. A ring-like member of a nonmagnetic material may be inserted in the aforementioned space.

    摘要： Voltage compensating circuits are connected serially to a power system, including capacitors each having different charging voltages (in relationship of approximately 2k (K=0, 1, 2, . . . ) times the smallest charging voltage value). The voltage compensating circuits convert DC voltages in the capacitors into AC voltages and output the AC voltages, respectively. The voltages of the capacitors are detected as detected values V1 to V3. The detected values V1 to V3 are used as bit signals for a reference value to check a voltage dip amount of the power system with the reference value and to convert the voltage dip amount into a binary signal. A combination is selected from the voltage compensating circuits in accordance with the binary signal so that the sum of output voltages of the selected voltage compensating circuits compensates the voltage dip of the power system.

    摘要： In semiconductor equipment, a switching timing adjuster is provided between insulated gate bipolar transistors and a control signal generator. The switching timing adjuster includes an input decision circuit that decides whether a signal output from the overvoltage protector is a signal that has been output due to a deviation in the switching timing at a turn-off or turn-on time, a signal holding circuit that holds a signal that is output from the input decision circuit, and a pulse formation circuit that forms a corrected switching control signal based on a signal held in the signal holding circuit and a switching control signal from the control signal generator.
