摘要： PURPOSE:To reduce the amount of leakage to the rear side of a second sidewall for reducing the load on a driver for capacity adjustment by a method wherein the inner circumferential part of the second sidewall is extended in the axial direction of a turbine impeller to form an L-shaped axial section, and an intermediate pressure chamber is formed between the second sidewall and an annular side plate. CONSTITUTION:P represents the pressure in an intermediate pressure chamber 9, P1 the pressure at the inlet of an entrance flow path 8, and P2 the pressure at the outlet. The pressure P varies depending upon the sizes of gaps at the inner and outer circumferences of a second sidewall 3 and a gap at the inner circumference of a slot 6, however, a relationship P1>P>P2 is established. As the second sidewall 3 having an L-shaped axial section is provided to form an intermediate pressure chamber 9, a thrust F= A(P1-P) is exerted on the second sidewall 3, where A is a sectional area perpendicular to the axial direction. By adequately adjusting the gaps, P=1/2(P1+P2) is established. The inner circumference of the second sidewall 3 serves as a weir, the differential pressure across the second sidewall 3 becomes small, resulting in an reduction of gas leakage amount to the rear side of the second sidewall 3.

摘要： PURPOSE: To improve the mechanical reliability. CONSTITUTION: This joint is a low temperature dissimilar metal joint in which one kind or more cushioning materials having a middle thermal contraction ratio between a conduit-side low thermal contracting material and a terminal- side copper is interposed between the both, and integrated thereto. Thus, the stress generated by the difference in thermal contraction ratio between the low thermal contracting material used in the conduit of a superconductor and the copper used in the terminal can be reduced to prevent the crack by cooling.

摘要： PROBLEM TO BE SOLVED: To provide a forcedly cooled superconducting coil apparatus which will not disturb the flow rate distribution, when the coil apparatus is conducted and a method for controlling flow rate when the coil apparatus is conducted. SOLUTION: A flow rate distributing ratio mcoil/mstr (conduction) while a sperconducting coil 100 is conducted, maintains an initial flow rate indicating time of the helium flow rate characteristic of a cooling section 102, namely, the flow rate distributing ratio mcoil/mstr (non-conduction) when the coil 100 is in a steady state before conduction or during a non-conduction period. In other words, the flow passage resistance of a support structure 104 is controlled by means of a flow control valve 10, so that ratio mcoil/mstr (conduction)=ratio mcoil/mstr (non-conduction) is established to invariably maintain the flow rate distribution to the cooling section 102 and the structure 104.

摘要： PURPOSE:To prevent the temp. difference depending on parts even at the time of heat treating a large sized long-length superconductor and to execute uniform and sure heat treatment by positively utilizing a refrigerant passage formed at the inside of a superconductor, circulating an inert gas heated to a prescribed heat treating temp. therein, and then executing heat treatment. CONSTITUTION:As shown in figure, in the method for heat treating a superconductor in the invention, an internal passage for passing a refrigerant formed at the inside of a superconductor 1 such as a superconducting coil is utilized, in which an inert gas 2 such as He, Ar and N2 heated to a prescribed heat treating temp. is forcedly circulated to the direction of the arrow shown in the figure, and heat treatment is executed. In this way, even in the case the superconductor 1 is a large sized long-length one, the temp. difference in the heat treatment depending on its parts is prevented, and uniform and sure heat treatment is permitted. The unevenness of the heat treatment is eliminated, and a stable superconductor can be formed. In this example, an inert gas 3 is heated to a prescribed heat treating temp. by an electric furnace 3, and this heated inert gas 2 is circulated in the internal passage of the superconductor 1 by a circulating pump 4.
