摘要： PROBLEM TO BE SOLVED: To obtain a reliable compact system by providing heat shields at the intermediate part of inner and outer diverters and cooling them with cooling water. SOLUTION: Inner and outer diverters 11, 12 are provided, at the intermediate part thereof, with heat shields 13 having a cooling water inlet header 14 (14a, 14b, 14c) and a cooling water outlet header 15 (15a, 15b, 15c). They are supported on a frame 16 (radial member 16a and circumferential member 16b). Cooling water is then fed from a cooling water inlet passage 17 provided in the member 16a to the header 14 in the member 16b and passed through cooling water supply pipes 19a, 19b, 19c and cooling water return pipes 20a, 20b, 20c in order to cool the diverter 11 and the heat shields 13 before being fed through the header 15 to a cooling water outlet passage 18. Consequently, generated impurities are discharged through the gap between the diverter 11, heat shield 13 and frame 16 while preventing stagnation and counter flow. Furthermore, installation space can be reduced because the frame 16 serves as the headers 14, 15 and passages 17, 18.

摘要： PURPOSE:To enable firm supporting even against a large electro-magnetic force and to prevent rapture of a keying member between a toroidal coil and a support member by forming an insulation layer of a keying member so as to corrugate in the poloidal direction of the toroidal magnetic field coil. CONSTITUTION:A support member 2 which supports electro-magnetic force Q, is provided between toroidal coils 1 which are arranged radially in a tolus direction of a vacuum chamber. A keying member 3 for supporting poloidal electro-magnetic force P is inserted in between the member 2 and the coil 1. The member 3 is formed as to be a three layers structure by being inserted by an insulation layer 5 which is formed corrugatedly between metal layers 4a and 4b in the poloidal direction of the coil 1. Also, on surfaces of the member 2 and the coil 1, an insulation layer 5 is formed. By corrugatedly forming of the insulation layer 5, the large electro-magnetic forces P and Q can be supported by the members 2 and 3, when the two forces work. Moreover, by providing the metal layers 4a and 4b on the both sides of the insulation layer 5, rapture of the member 3 can be avoided when the member 3 is driven in, and reliability of the member 3 is much improved.

摘要： PURPOSE:To surely maintain the soundness of a cooling base plate which has internally coolant flow passages by metallurgically joining the cooling base plate and a protective plate to the plasma side face of said base plate and further, joining a heat receiving plate to the plasma side of the protective plate. CONSTITUTION:The flow passages 102 for passing the coolant are formed to the cooling base plate 101 and the protective plate 103 is metallurgically joined to the base plate 101. The heat receiving plate 104 is fixed by an internal thread part 105 to the plate 103 and the thread part 105 is formed thinner than the other parts. The heat receiving plate 104 is bolted 106 to the plate 103. The heat receiving plate 104 in the part where the bolts 106 are screwed down is formed thin as well. Further, the top end face of the bolts 106 is recessed from the plane of the plate 104 in the screwed state of the bolts 106 to decrease the thermal load from plasma at the time of abnormal annihilation of the plasma on the bolts 106. An austenitic stainless steel is used for the material of the base plate 101, graphite for the protective plate 103 and a composite for the heat receiving plate 104 and the bolts 106. The weaving direction of the fibers of the composite is paralleled with the surface of the heat receiving plate 104 to prevent cracking.

摘要： PURPOSE:To securely support electromagnetic forces in a toroidal and a poloidal direction which operate on a toroidal magnetic field coil by composing a key member, which supports the electromagnetic force operating in the poloidal direction of a vacuum container, of a conic metallic material, and a cylindrical insulating material which covers the surface of the metallic material. CONSTITUTION:The electromagnetic force Q in the toroidal direction which operates on the toroidal magnetic field coil 2 is supported by a support member 6 and the electromagnetic force P in the poloidal direction is supported by the key member 7. When, for example, shearing forces Fa and Fb operate on the key member 7, the shearing forces Fa and Fb can be supported by the metallic material 8 since the key member 7 consists of the conic metallic material 8 and the cylindrical insulating material 9 covering the peripheral surface of the metallic material 8. Consequently, the key member 7 does not break even when a large electromagnetic force operates on the key member 7.

摘要： PURPOSE:To reduce the generation of the creep deformation of a gasket when baked and prevent the lowering of the bearing of a sealed face for obtaining a reliable metallic gasket by making the material near the part, with which the blade of a flange is brought into contact, of material whose hardness is lower than that of the material around the part. CONSTITUTION:The vacuum seal between a gasket 4 and flange 13 is performed by letting the blade 11 of the flange 13 cut into the sealing member of the gasket. When baking is done to reduce the quantity of gas discharging from a vacuum container, the temperature of a vacuum flange section rises, and since clamping force works to the cutting edge of the flange cut into the sealing member 1 of the gasket 4 due to the clamping bolt 12 of the flange 13, the creep deformation of the gasket 4 progresses. This deformation lowers the clamping force of the clamping bolt 12, which causes leak generation. Since, however, the internal peripheral surface, external peripheral surface, and bottom surface of the sealing member 1, into which the blade 11 of the flange cuts, is enclosed by a base member 2 whose hardness is higher than that of the sealing member 1, the deformation of the sealing member 1 is bound so that creep may not easily be generated, which reduces the generation of creep deformation.
