摘要： PROBLEM TO BE SOLVED: To lower production costs of a gas socket by eliminating a spring for energizing an operating member to the side of the removing position. SOLUTION: A retaining protruded part 15 with an angular cross section is formed on the internal surface of a guide hole 13 into which an operating member 40 is movably housed. The operating member 40 forms an elastic piece 45. The elastic piece 45 lets a contact part 45a of the tip part thereof hit the retaining protruded part 15 to keep the operating member 40 at the removing position. It is noted that the elastic piece 45 is elastically deformable to allow moving of the contact part 45a of the tip part to the right in the drawing 1. When the operating member 40 is pressed by a pressing force exceeding a specified value to a mounting position from the removing position, the elastic piece 45 is elastically deformed thereby getting the contact part 45a past the retaining protrusion 15.

摘要： PURPOSE:To eliminate possibility of damage and corrosionby inserting a pressure governing pipe which transmits secondary side pressure to a pilot into a secondary side piping in a governor unit, and locating its leading end opening at a position in the secondary side piping properly spaced on the downstream side. CONSTITUTION:A main valve 2 is arranged inside a governor unit 1, while a pilot 7 is arranged outside the governor unit 1. A pressure governing pipe 4 connected to the pilot 7 is arranged along an outer wall to a lower portion of the governor unit 1, and introduced into the governor unit 1. It is then inserted into a secondary side piping 3 of the main valve 2. Its leading end opening 9 is extended to a portion properly spaced from the main valve 2. Since the pressure governing pipe 4 is in the secondary side piping 3 outside the governor unit 1, it is possible to prevent accidental damage caused by a worker in another field, almost suppress corrosion, and provide resistance against fluctuation of ground.

摘要： PROBLEM TO BE SOLVED: To make a high performance compact structure by a method in which a male holding piece and a female holding piece are arranged in parallel on one catapillar and on the other catapillar respectively, each catapillar is driven through an one-way clutch, the clutch can be rotated idly when the drawing force of a winch is added. SOLUTION: The catapillars 1, 2 of a U-shaped folding pipe (a) receive driving force from driving devices 3, 4 through one-way clutches 5, 6. A male holding piece 7 having a projected part 7a which can be inserted into the opening part a1 of a U-shaped part is attached to a catapillar 1, a female holding piece 8 having a recessed part 8a which can be inserted into a folding part a2 is attached to the other catapillar 2, and each holding piece 7, 8 is arranged on the catapillar in the form of a large number of parallel lines. Since the male and female holding pieces 7, 8 hold the pipe (a), a large holding pressure is applied to obtain high performance. When the pipe (a) is drawn at a speed exceeding a push-in speed, the clutches 5, 6 are rotated idly to prevent the application of an unreasonable load on the driving devices 3, 4.

摘要： PROBLEM TO BE SOLVED: To provide an opening construction method for the branch part of a double pipe to open a branch port by simply removing an outside metallic pipe without damaging an inner layer pipe in a limited work pit. SOLUTION: When a part of a metal is removed to take out a branch pipe pertaining to a metallic pipe 1 provided on the inner side with a PE pipe 1a, breakage grooves B and B' are formed in both sides of an exposure scheduled spot A along a peripheral direction by means of a periphery cutter 2. In this case, when the cutter blade 2a of a periphery cutter 2 is cut through the metallic pipe 1 to some extend, a crack is formed from the breakage grooves B and B' in the inside radial direction of the pipe and the metal of the exposure scheduled spot A is separated from the metallic pipe 1. Thereafter, when the metallic part of the exposure scheduled spot A is vertically compressed by a squeeze tool 3, a cylindrical metallic part is not allowed to follow elastic deformation and a crack is formed in the axial direction of a pipe and fracture occurs. In this case, since an inner PE pipe 1a is abundant in an elastic force, damage does not occur to the inner pipe during compression and after compression, the pipe is restored to a cylindrical state.

摘要： PROBLEM TO BE SOLVED: To smoothly conduct both insertion and expansion-restoration of a folding pipe into a pipe conduit by forcibly cooling a pipe given a folding work immediately before the inlet of a pipe conduit at its outer surface from the outside while being restrained in the state to be set stationarily in a folded shape. SOLUTION: A pipe 1 passes through a deformation working zone A to a restraint cooling zone B during movement from a drum 2 toward a pipe conduit inlet a1. While being passed through the deformation working zone A, the pipe 1 is gradually deformation worked from a flat pipe shape to a U-shaped folded shape, and its effective outer diameter is reduced to be a size capable of being inserted in a pipe conduit (a). During the period of passing through the restraint cooling zone B, a U-shaped folded pipe is subjected to a forcible cooling operation in a configurationally restrained shape. A forcible cooling device 9 is installed over the substantially entire length of the restraint cooling zone B, and a cooling spouting mold 9a and cold air blowing mold 9b are applied so that the pipe is set stationarily by forcible cooling in a configurationally restrained shape as being folded into a U-shaped form.
