摘要： PURPOSE:To reduce emission gas, and to use an electron plate for ion source, and a magnetic filter even in a high temperature atmosphere by making a permanent magnet for magnetic filter attachable to and detachable from the external part of a vacuum container. CONSTITUTION:For an electrode plate 8b for ion source, an upper metal plate 41 of flat upper surface, a central metal plate 42 provided with a groove 44 for supply/ discharge passage of coolant as well as a through groove 45 for magnetic filter (for inserting permanent magnet), and a lower side metal plate 43 provided with a coolant supply/discharge passage hole 41, are put together, and are connected with each other by diffusion connection, which is mounted on a vacuum container of an ion source, while a permanent magnet 19 for magnetic filter is made attachable to and detachable from the external part of the vacuum container. For a magnetic filter 13, a magnet material before magnetization is inserted into a container 14 made of Cu or SUS material, which is non-magnetic, and which generates little emission gas to a vacuum part, and after the material is sealed in vacuum, it is magnetized, and is thus used. An electrode plate 8b and a magnetic filter 13 can thus be obtained, which generate little emission gas in vacuum, and which can forcibly cool the magnet 19, and for which the installation of the magnet 19 and the alignment of magnetic polarity are facilitated.

摘要： PURPOSE:To easily fit a metal plate to any position of a waveguide in any stage of production and to attain efficient electric contact by constituting a metal plate iris with a master metal plate and slave metal plates. CONSTITUTION:The metal plate iris 11 is constituted of one master metal plate 13 and two slave metal plates 14 in the rectangular waveguide 12. Both the side end surfaces 13c of the plate 13 are gradually approached to each other in the downward direction like inclined surfaces to form the plate 13 like an upside-down trapezoid and its lower end part is fixed on the waveguide 12 through a screw member 16 penetrated into a hole 15 perforated into the waveguide 12. On the other hand, the plates 14 are formed like trapezoids constituted so that respective outside end surfaces 14a form vertical surfaces and respective inside end surfaces 14b form inclined surfaces corresponding to the surfaces 13a of the plate 13 and soldered sheets 17 are formed on the surfaces 14a. Consequently, the metal plate can be easily fitted to any position in any stage of production even if soldering to the position is difficult, and electric contact between the metal plates and the waveguide can be improved.

摘要： PURPOSE:To reduce an equipment capacity by feeding detecting signal when the load of a power receiving system reaches a peak, to an NBI, RF operation controller, and by performing the shutdown of the CND operation of the NBI, RF. CONSTITUTION:When peak load detecting signal is generated, then this is taken in an NBI, RF operation controller 9, and while this signal is kept generated, the CND operation of an NBI, RF is controlled for quiescence to be performed. The CND operation of the NBI, RF is to be continuously performed for a long period, namely, for one day-several days, and even if the quiescence is performed by several shots once in several minutes-several ten minutes, any fault is not found. As a result, at the time of the peak load of a power receiving system, the shutdown of the CND operation of the NBI, RF is to be performed, and so as an incoming equipment, the only capacity of a generator power system should be taken into consideration, and the capacity of the NBI, RF is not required to be estimated, and so an economical equipment can be composed.

摘要： PURPOSE:To reduce the evaporation amount of the liquid helium and to improve the efficiency, by furnishing at least either a heat insulating material layer or a heat insulating space layer at the inner wall of a cryostat, in the device where the bottoms of a gyrotron and the cryostat are soaked in the insulating oil. CONSTITUTION:Inside the inner wall 2a of a cryostat 2 facing a hollow 17, a heat insulating material layer 18 is furnished, and moreover, at the inner side of the heat insulating material layer 18, a heat insulating space layer 19 is furnished. A partition wall 20 between the heat insulating space layer 19 and a vacuum layer 8 is installed to the cryostat 2 by welding or the like to keep airtight the both layers. By furnishing the heat insulating material layer 18 and the heat insulating space layer 19 at the inner wall 2a of the cryostat 2 where a severe temperature rise occurs, the increasing heat reaching to the vacuum layer 8 can be prevented by the local oil temperature rise of the insulating oil 11A inserting to the hollow 17. The generation of the outgasing amount is controlled at a low level, and the increasing consumption of the liquid helium owing to the vacuum degree deterioration of the vacuum layer B can be prevented.

摘要： PURPOSE:To suppress distortion without increasing the number of coil support parts by inserting a stiffening plate between the coil cases or between coil support parts. CONSTITUTION:To suppress downward distortion of a coil 1, a stiffening plate 5 is stretched over a coil case 2 by welding or with screws. In the space between the case 2 and the coil 1, a spacer 6 consisting of fiber-reinforced plastics, for example, is inserted to support the coil 1. For the stiffening plate 5, a nonmagnetic material having strength and stiffness such as stainless steel is used. Like this, the stiffening plate 5 is used only on the surface coil 1 distortion is presumed and the distortion of coil 1 is surely suppressed with a simple structure. The stiffening plate 5 can be connected to a coil support seat 3 or a coil support rib 4 to get the same effect.

摘要： 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.

摘要： PURPOSE:To make it possible to accomplish high accuracy and high current density by a method wherein a coil conductor is formed in hexagonal shape, and a positioning groove is provided at least on the lower surface of a coil case or a spool. CONSTITUTION:A coil conductor 1 is formed into hexagonal shape, and an alignment groove is provided on the lower side of a coil case (or bobbin) 2. The conductor of the first stage is wound along the groove on the lower surface of the coil case (or bobbin). Surface contact is maintained between each conductor through one face of the hexagonal shape. Pertaining to the conductors of the second stage and succeeding stages, the conductors other than both ends of even stages and odd stages are wound along the grooves formed by tvo conductors of the former stage, and also the conductors on both ends of off stages are wound by applying tension in conformity with the space formed by one conductor of the former stage and the side face of the coil case (or bobbin), and a helical coil is formed. As above-mentioned, each conductor is bought into a surface-contact state in many directions when it is wound, the conductor itself performs the function of supporting the next conductor, and as a result, a tension winding can be made possible. Consequently, a helical coil having high rigidity and high preciseness can be formed.
