摘要： PURPOSE:To produce a sound structure free from blow holes by subjecting electroformed copper to electron beam welding with an Al or Ti spacer. CONSTITUTION:When pieces of electroformed copper are joined by electron beam welding, a Ti or Al insert is used as a spacer so as to prevent the occurrence of blow holes. Since the insert is used by a small amt., the characteristics of the electroformed copper are not affected by the insert. A sound structure free from blow holes can be produced at a low cost by joining electroformed copper used for a superconducting accelerating cavity for synchrotron radiated light by electron beam welding with the insert.

摘要： PURPOSE:To efficiently cool a superconducting coil by injecting refrigerant helium gas when the temperature of the superconducting coil is high, externally precooling the coil, and feeding the gas into the the coil to cool it when the temperature of the coil drops. CONSTITUTION:When the temperature of a superconducting coil 21 is high, a helium injection valve 29 is opened to inject refrigerant helium gas from a refrigerator from the valve 29, and the coil 21 is externally precooled. The injected gas is sucked from a suction valve 31, and returned to the refrigerator. When the temperature of the coil 21 is reduced by precooling, the valves 29, 31 are closed, and the gas is fed in the coil 21. In this case, since the coil 21 is precooled, the gas is smoothly fed into the coil 21. Remaining gas in a vacuum tank 12 is discharged by a vacuum pump 14. Thus, the desired coil can be efficiently cooled.

摘要： PURPOSE:To provide a forming method of a superconducting thin film for forming the superconducting thin film on an inner surface of a cavity with good adhesion and good heat conductivity, and a formation device thereof, CONSTITUTION:After a cavity 11 is stored in a film formation airtight chamber 2 and a thin film of the same material as the cavity 11 is formed as an intermediate layer, the cavity 11 is moved to a load lock chamber (vacuum airtight chamber) 3, and a gate 4 is closed, while the vacuum condition is retained. A sputtering target 10 of the film formation airtight chamber 2 is replaced with the one for superconducting thin film, while the vacuum condition is formed again, and the cavity 11 is returned from the load lock chamber 3 to the film formation airtight chamber 2, and a superconducting thin film is formed on the intermediate layer.

摘要： PURPOSE:To manufacture pressurized HeII within a short period of time by a method wherein an inside part of a container is reduced in its pressure, liquid helium is cooled to change it into saturated ultra-flowing helium, helium is thermally insulated at an intermediate part of liquid layer, a cold state keeping region is formed below it, the inside part of the container is pressurized and then pressurized region flowing helium is produced within the cold state keeping region. CONSTITUTION:A safety valve 16 is opened, HeI is inputted into a container, and a liquid surface level 28 of HeI is set higher than that of a separator 12. A vacuum pump is operated to discharge evaporated He in a container 10, an inside part of the container 10 is reduced in its pressure to generate saturated HeII and then the safety valve 16 is closed. Although an upper part and a lower part of the saturated HeII are thermally insulated with a separator 12 being applied therebetween, a slight clearance is present between the safety valve 16 and the separator 12, so that pressure above the separator 12 and pressure below the separator 12 are kept uniformly to each other. A compressor is operated to supply helium gas into the container 10 and an inside part of the container 10 is pressurized substantially up to atmospheric pressure. Saturated HeII present in the pressurized HeII tank 14 acting as a cold state keeping region is pressurized substantially up to atmospheric pressure while being kept at a low temperature state and then the pressurized HeII is produced.

摘要： PURPOSE:To prevent the breakage of an engine by installing an intermediate power transmission member which is fitted in integrally rotatable manners with a screw rotor shaft on the drive side, screw side gear which is fitted with the power transmission member and meshed with an engine side gear, and a pressing means, onto the shaft edge part of the screw rotor shaft. CONSTITUTION:An intermediate power transmission member 15 has a trailing side contact surface 18 for generating a torque by a slide friction, and joined with the rotor shaft 19 of a screw rotor 2 through spline 20, and supported by a bearing 21, and can be revolved integrally with the shaft 19. While, a screw side gear 16 has a drive side contact surface 22 which contacts the contact surface 18, and is fitted with the projection part 23 of the member 15 and is supported in rotatable manners by a bearing 24. Further, a bolt 26 screwed with a tapped hole 25 formed on the member 15 is engaged with a patch plate 27 fitted onto the edge surface of the gear 16, and the gear 16 is pressed onto the member 15 by the bolt 26, and the frictional force between the both is adjusted. When the screw rotors 2 and 3 are locked, a slide is generated between the both surfaces 18 and 22, and the application of an excessive torque onto a crankshaft 1 is prevented.

摘要： PURPOSE:To prevent hydrogen remaining when a heat-conductive covering layer is formed, hydrogen generated when an aluminum alloy shape melts, etc., from contaminating a superconducting thin film and to surely prevent the degradation of its superconductive characteristic by forming the superconducting thin film in a final process. CONSTITUTION:The external surface of an aluminum alloy shape 1 is specularly finished, after that, an external surface 14 of the shape 1 is covered with metallic material of good heat conductivity, thus, a heat-conductive covering layer 3 having the same internal surface shape as the external surface shape of the shape 1 is formed, after that, only the shape 1 is melted and removed and a superconducting thin film 4 is formed closely on the internal surface of the heat-conductive covering layer 3. Since the superconducting thin film 4 is formed in the final process like this, the hydrogen remaining when the strengthening covering layer is formed, the hydrogen when the aluminum alloy shape 1 melts, etc., do not contaminated the superconducting thin film 4 and thus, the degradation of its superconducting characteristic can be prevented.
