摘要： PROBLEM TO BE SOLVED: To provide an open part structure, and an opening method capable of isolating atmospheric fluid outside piping from fluid inside the piping without using a vinyl bag or an air bag. SOLUTION: A feed nozzle 4 to feed gas is provided on the piping close to a device open part, and a gas discharge sparger 5 communicated with the feed nozzle 4 is disposed inside the piping 1. A gas suction port 6 is disposed on the piping having position relation to face the feed nozzle, and inert gas is supplied from the feed nozzle, while inert gas is sucked from the gas suction port, so that a gas curtain 23 is generated between the gas discharge sparger and the gas suction port. The gas discharge sparger communicated with the feed nozzle is disposed along a circumferential part of the piping, and the gas suction port is disposed to have position relation to face the feed nozzle. The diameter of the gas discharge sparger and the gas suction port is set to be larger than the diameter of the piping.

摘要： PURPOSE:To draw out a liquid remaining in a heat transfer pipe earlier and to prevent stress corrosion cracks, pit corrosion and the like from occurring by using an air feed pipe for ejecting a gas and an exhaust pipe for absorbing liquid drops scattered by the ejection of the gas in a U-shaped heat transfer pipe. CONSTITUTION:A dual pipe consisting of an air feed pipe 28 and an exhaust pipe 25 is inserted up to the lower end portion of a U-shaped pipe of a heat transfer pipe 1. A high speed gas 33 is ejected from the air feed pipe 28 to the inner wall surface of the heat transfer pipe 1 through a gas ejection path 32. Water 14 remaining at the lower part of the heat transfer pipe 1 is scattered in the form of waterdrops 34 and absorbed from a water recovering part 27, and discharged outside the heat transfer pipe 1 through an exhaust pipe 25. Simultaneously, waterdrops 35 adhering to the inner wall of the heat transfer pipe 1 is similarly scattered and absorbed from the water recovering portion 27. By these operations the liquid within the heat transfer pipe 1 is completely removed. Consequently, generation of stress corrosion cracks, pit corrosion and scales in the heat transfer pipe due to the concentration of impurities in the residual liquid can be prevented.

摘要： PROBLEM TO BE SOLVED: To facilitate a hoisting work of a hoisted cargo by a crane, to shorten work time and to improve safety of the hoisting work.
SOLUTION: When a manipulator 10 is separated after a spherical surface hook 4 mounted on a hoisting chain 3 is dropped into a guide hole 7a of a hoisting metal fitting 7 by using the manipulator 10, the hoisting chain 3 is guided into a hoisting chain through hole 7b of the hoisting metal fitting 7, and at the same time, a spherical surface of the spherical surface hook 4 is engaged to a fitting groove 7c of the hoisting metal fitting 7 provided on a lower side of the through hole 7b. Thus, when the hoisting chain 3 is hoisted by the crane 1, the hoisted cargo is hoisted since the spherical surface hook 4 is engaged to the fitting groove 7c of the hoisting metal fitting 7. By using the crane 1 in which a plurality of spherical surface hooks 4 are mounted on the hoisting chain 3 to hoist the hoisted cargo by being connected in a row, the hoisting length when hoisting the hoisted cargo can be adjusted.

摘要翻译：要解决的问题：为了方便起重机提升的货物的起重作业，缩短工作时间，提高吊装作业的安全性。解决方案：当安装在提升链3上的球形表面钩4通过使用操纵器10落入提升金属配件7的引导孔7a中之后，将操纵器10分离时，将提升链3引导到提升金属配件7的提升链通孔7b，同时球面钩4的球面与设置在通孔7b的下侧的提升金属配件7的配合槽7c接合。因此，当起重机1由起重机1提升时，由于球面钩4与起重金属配件7的嵌合槽7c接合，所以提升的货物被提升。通过使用起重机1，其中多个球形表面挂钩4安装在起重链条3上，通过连接成一体地提升起重货物，可以调节提升悬挂货物时的起重长度。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To provide a lifting apparatus capable of facilitating lifting work of a lifting load, shortening a working time, and providing improvement in safety of the lifting work.
SOLUTION: This is the lifting apparatus of which the lifting means is constituted of a plurality of joint members 3 linked together like beads connected with a crane 1, at least one spherical surface hook fixing fixtures 5 attached between the joint members 3 adjacent to the spherical surface hook 4 attached on the joint members 3. The joint member 3 and the fixing fixture 5 can pass through a through hole provided at a center of the spherical surface hook 4. The spherical surface hook 4 is supported on a surface of the fixing fixture 5 at an appropriate position with a support bolt 7 for supporting the spherical surface hook 4 protruded from an inner portion of the spherical surface hook 4.

摘要： PURPOSE:To improve toughness in a weld zone and also to relieve residual welding stress, by subjecting a heat-transfer pipe of a heat exchanger and a hub of a pipe plate to butt welding and then applying heat treatment to the weld zone under specific conditions. CONSTITUTION:The heat-transfer pipe 2, composed of high-Cr steel containing, as principal components, 8.0-10.0wt.% Cr and 0.8-1.2wt.% Mo, of a heat exchanger and the hub 3a of a pipe plate 3 composed of high-Cr steel are allowed to abut each other and subjected to inert-gas tungsten-arc welding by the use of filler metal. Subsequently, the weld zone 4 is rapidly heated up to a temp. in a temp. region of the Ac3 transformation point or above, 900-960 deg.C, from the inside by means of a high-frequency heater 6, and the outside is cooled rapidly down to ordinary temp. by passing water 10. Further, high-frequency heaters 6, 7, 8 are electrified, and a residual welding stress zone 9 including the weld zone 4 is heated from the inside up to 700-760 deg.C and then cooled slowly. In this way, a coarse-grain zone in the weld zone 4 is refined and formed into a stable tempered martensite structure, so that toughness is improved and residual welding stress is relieved.
