摘要： PROBLEM TO BE SOLVED: To provide a man-hole sealing structure for a pressure vessel, actualizing reliable sealing and easy opening/closing. SOLUTION: The structure comprises an elastically deformable annular seal member 3, a cover member 4 inserted into a man-hole pipe 2 with the seal member 3 mounted on the outer periphery and having a seal face 4a for contacting the seal member 3 in opposition to the end face on the inward side in the axial direction, and a holding member 5 detachably mounted at the outer end of the man-hole pipe 2 for contacting the seal member 3 in opposition to the end face on the outward side in the axial direction while holding the cover member 4 slightly movable in the axial direction together with the seal member 3. The cover member 4 receiving pressure in the pressure vessel is slightly moved outward in the axial direction, whereby the seal member 3 is compressed in the axial direction and expanded in the radial direction to be pressed against the inner peripheral face of the man-hole pipe 2 and the outer peripheral face of the cover member 4.

摘要： PROBLEM TO BE SOLVED: To omit work for replacing metal gasket with an O-ring. SOLUTION: Into a bolt hole 12 machined with a taper, a taper sleeve 15 is inserted. A primary lid 4 is fixed to a flange part 2 of a shell body 1 through the cylinder of the taper sleeve 15. Also, a taper sleeve 23 is inserted in a bolt hole 20 machined with a taper and a secondary lid 7 is fixed to the flange part 2 of the shell body 1 through the cylinder of the taper sleeve 23. With this method, radial motion of the primary lid 4 and the secondary lid 7 is a disturbed and sliding of the metal gasket 6 and 10 is prevented. Thus, a cask 100 can be transported only with metal gaskets 6 and 10.

摘要： PROBLEM TO BE SOLVED: To provide a method for detecting penetration defects of a line which is capable of detecting whether or not there are penetration defects of the line as well as specifying the locations of the defects in a short time with high accuracy, and an apparatus therefor. SOLUTION: A pair of elastic rubber films 12a and 12b expanding toward the inner peripheral surface of the line A on being exerted with pressure fluid are inserted into the line A while in predetermined spaced relation along the direction of the pipe axis and are expanded by the fluid pressure until making contact with the inner peripheral surface of the line A to form sealing walls αand βdividing the interior of the line A along the direction of the pipe axis; the sealed space 33 of the line A divided by the sealing walls α and β is pressurized, after which a pressure sensor 34 detects whether or not there are penetration defects of the line depending on the rate of pressure drop in the sealed space 33. Thus, detection of penetration defects of the line A leading to leakage can be carried out not for the entire line but for each part of the line A, so that only a sealed space of small volume is needed.

摘要： PROBLEM TO BE SOLVED: To provide a packing which can reduce a frictional amount generated by friction with a body of rotation, while improving sealing performance of an axial seal mechanism using the packing, and to ensure reliability toward a water power machine using the axial seal mechanism.
SOLUTION: The packing 17 is provided in the clearance between a runner 12 and a turning mechanism 14a and the packing 17 has a projection 18 extending in the radial direction of the packing 17 in the two places of the side surface opposed to the outer peripheral surface of the turning mechanism 14a, namely, its inner peripheral surface. And the packing 17 is held in the clearance between the runner 12 and the turning mechanism 14a in a state that the tip end portion of the projection 18 closely contacts the outer peripheral surface of the turning mechanism 14a, while the total outer peripheral surface sticks fast to the inner peripheral surface of the packing holder 19. By this way, the clearance between the runner 12 and the turning mechanism 14a is sealed with the packing 17 by closely contacting and holding the packing 17 to the packing holder 19 and the turning mechanism 14a.

摘要： PROBLEM TO BE SOLVED: To realize a gas leakage test when providing a metal seal in a lid of a cask.
SOLUTION: This leakage test device 200 performs the test by applying a load onto a central block 201 by a cylinder 220. The block 201 moves downward by the load application, so that an airtight state by a metal gasket 204 changes. Helium gas is supplied into a minute gap 208 from a gas cylinder 211, and its leakage amount is changed by the change of the airtight state of the metal gasket 204. The leaked helium gas is leaked into a gap 209 between the metal gasket 204 and an O-ring 206, and is detected by a gas detection device 213 through a passage 212 communicating with the gap 209.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for evaluating and testing characteristics of a metal gasket, capable of precisely evaluating the characteristics of a metal gasket.
SOLUTION: The annular test metal gasket 32 is held between first and second metal flange members 11 and 12 with a prescribed clamping force. The metal gasket and the test metal flange member clamped with the prescribed clamping force are heated at a prescribed temperature for a prescribed period of time inside a heating furnace and made to deteriorate with the heat. After that, a load is applied to the first metal flange member in the direction orthogonally crossing the center axis of the metal gasket with the second metal flange member being fixed. The quantity of displacement of the first metal flange member when loaded is measured and the leakage of the metal gasket is inspected, so that the leakage rate relative to the quantity, of displacement of the first metal flange member is calculated.

摘要： PROBLEM TO BE SOLVED: To provide a method and device for evaluating the property of a metal gasket, allowing the accurate evaluation of the property of the metal gasket. SOLUTION: A circular test metal gasket 32 is arranged between the peripheral edges of metal flange members 10, 11 opposing each other and the test metal gasket is held between the metal flange members with predetermined fastening force by fastening with a plurality of bolts 16 provided along the peripheral edges of the metal flange members. The metal gasket fastened with the predetermined force and the test metal flange members are heated for a preset time at a predetermined temperature in a heating furnace 28 to give heating deterioration to the test metal gasket. In the process of heating deterioration, the degradation of the fastening force is measured by using a strain gage 20 provided on at least one of the bolts for evaluating the stress relaxation property of the test metal gasket.

摘要： PROBLEM TO BE SOLVED: To omit a work of replacing metal gasket with an O-ring. SOLUTION: When contact surface pressure of the metal gasket is lowered by a fall during transportation, a secondary lid 508 is deformed to dent as a whole in the state supported by a projection 3 by tightening a bolt 511 and the depression quantity of the metal gasket 518 is increased. By this method, tight seal performance of the metal gasket 518 can be recovered. Thus, the cask can be transported only with the metal gasket without replacing with an O-ring.

摘要： PURPOSE:To expand the service range of swimming pool facilities by varying a floor form of this pool partially. CONSTITUTION:An end flooring 1 and an intermediate flooring 3 are shifted, while a pressure fluid is fed to a rod side pressure chamber of positioning cylinder, making a piston rod retreat to some extent, and it is extracted out of a positioning hole installed in a pool side wall, thereby making both these end and intermediate floorings shiftable. Next, the pressure fluid is fed to a bladder 4 set up in a lower side of the flooring to be raised out of a pressure fluid feeder 6, while being inflated, the pressure fluid is exhausted out of an inner part of the bladder set up in the lower side of the flooring to be lowered, and each bladder is contracted, and the flooring is shifted. In addition, a cylinder 11 built in each end flooring at both sides is expanded or contracted, then an expansion plate 12 is expanded or contracted, whereby an amount of overs and shorts in the horizontal direction due to inclination in the intermediate flooring is compensated. Successively the pressure fluid is operated in the expansion direction of he positioning cylinder, making the piston rod advance forward, and it is inserted into the positioning hole installed in the pool-side wall.
