摘要： PURPOSE:To function a measurement controller continuously even when a power source facility is stopped by switching an initial power receiving system into a commercial power source at the time of pausing of a power generation facility, during which the power necessary for maintaining the function is fed to the measurement controller from a power storage device. CONSTITUTION:Initial power receiving is carried out from a power source facility 9 with an initial power receiving system switcher 12 closed and an initial power receiving system switcher 13 open, at the time of driving a corpuscular beam source, while a power storage device 15 is charged. When the generation of the facility 9 is stopped following the pause of a corpuscular beam source 4, the switcher 12 is opened while the switcher 13 is closed before pausing the generation of the facility 9, and an initial power receiving system 14 is switched from the facility 9 into a commercial power source 11, and the generation of the facility 9 is paused thereafter. Power is fed from the power storage device 15 during the pause of the facility 9.

摘要： PURPOSE:To suppress a surge simply and easily and to improve the operation stability of a circuit by using for a power transmission line a conductor cable made of a functionally graded material of which the resistance value is increased from the central part toward the surface part. CONSTITUTION:A conductor cable 1 used for a surge suppression type power transmission line is made of a functionally graded material of which the resistance value is increased from the central part toward the surface part, and the cable 1 itself is made to have a surge suppressing function. Therefore the conductor cable 1 is a line having a larger impedance for a high-frequency component, and thereby a surge flowing through the surface of the conductor cable 1 as the power transmission line is suppressed and absorbed by a skin effect. Accordingly, the surge generated in the conductor cable 1 itself can be suppressed and absorbed.

摘要： PURPOSE:To enable the direct power reception from a commercial power system by connecting a variable resistor in parallel with electric facilities when the electric facilities, which receive power supply from the power system, cause sharp power fluctuation. CONSTITUTION:When the electric facilities receiving power supply from a power system 12 produce the power fluctuation in the reductive detection being sharp enough to fluctuate the voltage, etc., of this power system 12, switches 28a-28c are actuated to connect variable resistors 26a-26c in parallel with the electric facilities, and the amounts of power fluctuation are consumed once with these variable resistors 26a-26c. Next, the resistance values of the variable resistors 26a-26c are increased for a specified period, so that the power from the power system 12 to the power system suppressor 24 side may fluctuate slowly, so as to decrease the consumption power. And when the consumption power of the variable resistors 26a-26c has become small, the variable resistors 26a-26c are separated from the power system 12 by the switches 28a-28c.

摘要： PURPOSE:To absorb energy generated at the time of causing discharge breakdown through an electric resistor so as to prevent any deterioration of the withstand voltage of an accelerating electrode and any damage due to the fusion thereof by making up the accelerating electrode of the electric resistor. CONSTITUTION:Each of accelerating electrodes 30, which has a rectangular plate-like shape and the whole of which is made up of an electric resistor, has many ion-passing holes 18 bored therethrough, with a feeder line 22 making a high voltage impression provided at one end thereof. When a high voltage is impressed between their respective adjacent accelerating electrodes 30 in order to accelerate ions, then energy of each of the accelerating electrodes 30 themselves tries to flow into a discharge breakdown point on each of their planes. The energy of each of the accelerating electrodes 30 themselves, trying to flow into the discharge breakdown pointy, is however absorbed by each of their own resistors because each of them is made up of the electric resistor. Whereby deterioration of the withstand voltage of the accelerating electrode and any damage due to the fusion thereof can be avoided.

摘要： PURPOSE:To change converging speed of a multi-ion beam by arranging a variable converging electrode in the shape of running along both electrodes between a porous load-out electrode and a porous intermediate electrode, and making applied electric potential variable. CONSTITUTION:A cesium molecule turned into steam in a cesium oven 8 is supplied to an anion generating part 2 through a supply pipe, and the plasma is excited by impressing voltage on a plasma electrode 1, and is turned into an anion. An electron or the like generated in the anion generating part 2 is prevented from leaking by a corona shield 7. The anion is pulled out as a multi-ion beam from a porous pullout electrode 3 situated under the anion generating part 2, and is accelerated while passing through a porous intermediate electrode 4 and a porous earth electrode 5, and is turned into high energy, and flows out from an accelerating tube 9. A curving degree of an electric field between accelerating electrodes changes by changing electric potential applied to a converging variable electrode 6, and since beams in respective holes are converged or diverged, the multi-ion beam is converged at prescribed converging speed.

摘要： PURPOSE:To produce a charged particle beam carrying a large current, good in the converging characteristic, and equipped with a high brightness by arranging a plurality of magnets around electrode hole provided in each accelerating electrode, and generating a quadripolar magnetic field within this electrode hole. CONSTITUTION:In an electrostatic acceleration system 2 to accelerate a charged particle beam by permitting it to pass through a single electrode hole 1, magnets 5 to generate a pair of quadripolar magnetic fields 4a, 4b are installed above and below and on the left and right of each of accelerating electrodes 3 in multi-stage arrangement. When a charged particle beam is incident to the downstream quadripolar magnetic field 4A, the beam has a larger energy than when situated further downstream, and therefore, a charged particle beam converged both in the horizontal and vertical directions is obtained by giving the upstream quaripolar magnetic field 4B a greater intensity than the other 4A.

摘要： PURPOSE:To build up an output current at a great speed by providing a bypass circuit, which consists of a series circuit comprising a resistor and a switch for bypassing, in parallel with a series circuit comprising a switch and a load, when supplying a DC output obtained from a rectification of AC to a load, that is an ion source, through a DC reactor and a semiconductor switch. CONSTITUTION:In a normal operation state, a current is supplied to an ion source 10 driving a GTO 8 during the operation period of a AC thyristor switch 2. After that, if short-circuit would occur in the ion source 10, GTO operation signal 12 provides a down-edge, that is a GTO off command, to turn off the GTO 8 so as to interrupt an output current to the ion source 10. And, in a bypass circuit operation controll circuit 17, a bypass circuit operation signal 18 is generated by the down-edge of the signal 12 to turn on a GTO 15. Consequently, the output current is built up at a great speed, when reclosing the ion source 10 after it is interrupted, by equalizing a resistor 14, connected to the GTO 15 in a circuit 13, to the resistance value of the ion source 10 as a load, when the interrupted output current is communicated into the circuit 13.

摘要： PURPOSE:To give a radiation shielding ability and high insulating property to a high voltage feeder and, at the same time, to shield radiation without making any special construction work to the perforated section of the partition of a building by forming a labyrinth structure composed of a material having a radiation shielding ability between an inner and outer tubes. CONSTITUTION:A plurality of projections 13 made of a material having a radiation shielding ability are fitted to the external surface of an inner tube 9 in the axial direction toward an outer tube and a plurality of projections 14 made of the material having the radiation shielding ability are fitted to the internal surface of an outer tube 10 in the axial direction toward the inner tube 9. The projections 13 and 14 are fitted to the inner and outer tubes 9 and 10 so that the projections 9 and 10 can form a labyrinth structure, with the projections 13 and 14 overlapping each other at some places, when the tube 9 is put in the tube 10. Therefore, no radiation leakage occurs through a high voltage feeder, because the radiation passing through the space between the inner and outer tubes 9 and 10 is scattered, absorbed, and attenuated by means of the projections 13 and 14 respectively fitted to the tubes 9 and 10.
