Title: Hatch reinforcing structure of cylindrical pressure vessel
Inventor: AIDA JUICHI
IPC: F16J13/22
Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To prevent deformation of a hatch member caused by deformation of a peripheral wall of a cylindrical pressure vessel, and prevent the deterioration of sealing performance with a door member by arranging and constituting a reinforcing member continuing in its circumferential direction on the outer periphery of an opening end part on the opposite side of an end part where the door member of the hatch member is arranged. SOLUTION: When internal pressure of a pressure vessel 1 increases, a cross- sectional circular hatch member 20 is pulled by double force in the circumferential direction to the direction in parallel to the central axis of the pressure vessel 1 according to its pressure increase. As a result, though it tends to deform in an elliptic shape whose circumferential direction is set as the major axis, a reinforcing ring 40 resists this deformation, and prevents deformation of a hatch member 20 into an elliptic shape, and restains a diametrical change very small. Therefore, pressure contact sealing part of the hatch member 20 is prevented from being displaced large in the radial direction to a door member 30 whose diameter does not change even by an increase in internal pressure, and sealing performance is held.

Title: Joining method of titanium sheet
Inventor: KAMATA KEIICHI
IPC: B23K11/18
Filed: 1994-02-25
Abstract: PURPOSE:To join a high performance titanium sheet not having damage from fire and strain by covering a steel structure with a titanium sheet through a sandwiching material and subjecting the structure to resistance seam welding while pressing the lower side of titanium sheet lapped part with a copper plate. CONSTITUTION:A titanium sheet 3a of the lower side of titanium sheets 3, 3a lapped part is pressed by a copper plate 4, the welding heat generated at resistance seam welding is absorbed and the weld zone is cooled. Since the copper plate 4 and welding electrode 5 to press the titanium sheet 3a are approached near the titanium sheets 3, 3a lapped part, the cooling effect and energizing resistance of a sandwiching material 2 and weld zone 7 are lowered. Thus, the sandwiching material 2 at the lower side of the titanium sheets 3, 3a lapped part is not damaged by fire and softened, the strain at the joined part is not generated. Further, when the titanium sheets 3, 3a are over heated and an oxide film is formed on surface, discolor does not occur.
