    • PROBLEM TO BE SOLVED: To improve quality and to improve job site workability by consisting a high frequency transmission system of a corrugated waveguide which improves precision and production efficiency. SOLUTION: A corrugated waveguide 8 is formed by laminating and fixing a lot of big conductive rings 10 and big conductive rings 11, whose surfaces are composed of high-conductivity materials at least, mutually in axial direction. Besides, connection flanges 9 are fitted at both terminals. In this case, sliver brazing soldering or solid phase diffusion joining is used as a method for fixing the respective conductive rings. Thus, not only two kinds of conductive rings 10 and 11 can be extremely easily produced with high precision but also a corrugated tube 8 for a desired length can be provided by combining a log of two kinds of conductive rings 10 and 11. Besides, since one tube is long even when a high frequency transmission system 3 is extended for a long distance, a connecting part for connecting each corrugated waveguide through the connection flange 9 is reduced and job site work can be simplified.

    • PURPOSE:To achieve good economy and enhance the service efficiency by forming a circuitry with which the capacities of a transformer for power supply to arcs, a rectifier, a smoothing capacitor, etc., can be decided not with the arc ignition voltage but with the arc discharge voltage. CONSTITUTION:When a semiconductor switch 4 is in put-off state, a capacitor 7 is charged through a smoothing capacitor 3 and a circulating flow resistance 8, and if the switch 4 is put on at completion of this charging, the capacitor 7 makes discharging through the switch 4 and a reactor 6. This leads to occurrence of a resonance of the capacitor 7 and reactor 6, and the polarity of the capacitor 7 is inverted to be willing to invert the current, which is however blocked by the switch 4. Because the polarity of the voltage of capacitor 7 is identical to the polarity of the smoothing capacitor 3, a voltage approx. twice as large as the supply voltage stored in the smoothing capacitor 3 is impressed on the ion source 5. Accordingly the capacities of transformer 1, rectifier 2, capacitor 3, etc., are decided with the arc discharge voltage, which permits accomplishing a device with good economy and high service efficiency.

    • PURPOSE:To set the number of revolutions of a motor-generator so as to be optimum for every operation shot and to operate the title control device in an energy-saving manner by a method wherein the acceleration of the generator is started at a point of time which dates back by the acceleration time operated from a point of time when electric power is supplied to a load. CONSTITUTION:An operation control device 4 is provided with an acceleration-time calculating part 5 and a target-number-of-revolutions setting part 6. It transmits instruction data to a driving-motor control device 3 in such a way that the drive of a generator 1 is started earlier than a point of time, when the generator is started, by the time corresponding to the acceleration time operated by the acceleration-time operation part 5. Then, when a load is heavy, i.e., energy is used much, the target number of revolutions is set to be high, and the acceleration time becomes long. When the load is light, i.e., the energy is little used, the target number of revolutions is set to be low, and the acceleration time becomes short. Consequently, since the target number of revolutions can be set freely by taking various operation conditions into account, the time in which the generator is operated at a high number of revolutions can be reduced to a required minimum, and a power consumption can be reduced. As a result, the operation control device can be operated in an energy-saving manner.

    • PROBLEM TO BE SOLVED: To control the burnout of a superconducting coil at quenching while keeping low the breakdown voltage and rated voltage of the superconducting coil and a direct current power supply. SOLUTION: The high-temperature superconducting magnet system includes a plurality of subsystems. Each of the subsystems includes a plurality of high-temperature superconducting coils 10, 20 and direct current power supplys 11, 21. The high-temperature superconducting coils 10, 20 and the direct current power supplys 11, 21 are series connected in each of the subsystems. The high-temperature superconducting coils 10, 20 are disposed so as to form a strong electromagnetic coupling with the high-temperature superconducting coils belonging to the other subsystems 20, 10. When a quenching phenomenon occurs in the high-temperature superconducting coil 10 in the group (a), the current supplied by the direct current power supply 11 of the group (a) is decreased, and the current supplied by the direct current power supply 21 of the group (b) is increased so as to almost preserve the magnetic flux of the whole system before and after the occurrence of the quenching.
