摘要： PROBLEM TO BE SOLVED: To prevent a socket from being incapable of connection with a plug by providing a stopper part obstructing rotational movement of a disengaging member in the detaching direction. SOLUTION: In this gas plug socket 10, because the rotationally moving range of a disengaging member 40 in the detaching direction is regulated by a stopper part 44, an energizing means used for a customary gas plug socket can be omitted. Further because the disengaging member 40 is not largely rotationally moved from a detaching position in the detaching direction, when the extreme end face of the socket S (the extreme end face of a moving cylinser S2 ) collides with the disengaging member 40, the disengaging member 40 can not be rotationally moved, and it is surely avoided that the socket S can not be further inserted in a plug 32. Consequently the socket S can be surely connected to the plug 32.

摘要： PROBLEM TO BE SOLVED: To provide a resin pipe drawing-in technique for preventing the breakage and the like when a new pipe is drawn into an existing pipeline and carrying out the normal drawing-in operation all over a regenerated area of the existing pipeline. SOLUTION: In a resin pipe drawing-in technique, a resin pipe 16 composed of thermoplastic resin is drawn into an existing pipeline buried underground. In that case, an inside supporting member 10 of the taper cone shape for inserting a longitudinal direction end of the resin pipe 16 and an outside supporting member 11 with its inner face of the shape of being fitted on the outer peripheral face of the inside supporting member 10 are used, and in the state of inserting the inside supporting member 10 into a longitudinal direction end of the resin pipe 16, the end of the resin pipe 16 is made to adhere firmly on the outer peripheral face of the inside supporting member 10, and the outside supporting member 11 is fitted with the inside supporting member 10 across the resin pipe 16, and the inner face of the outside supporting member 11 is pressed on the outer peripheral face of the inside supporting member 10 to clamp the resin pipe 16, and the inside supporting member 10 is hauled. The resin pipe supporting member 10 can be drawn into an existing pipeline by the arrangement.

摘要： PROBLEM TO BE SOLVED: To suppers temporary abnormal boosting on a second side caused by the full opening of a governor because of failure or breakage on the second side only by incorporating a simple mechanism. SOLUTION: A detecting pipe 21 detecting he breakage of the second side is connected to the pressure governing pipe 13b of a conventional mechanism to incorporate safety mechanisms 22 to 24 operated by the reduction of pressure on the second side detected by this detection pipe 21 to operate an interruption valve 15 at the time of the breakage or the failure on the second side to plug a pipeline on a first side 11 before the governor 10 is fully opened.

摘要： PURPOSE:To detach a lid without impact and to easily exchange a filter element by rotating the central shaft of the lid to insert a flange projecting from the periphery of the lid into a groove on the inner periphery of an outlet and to fix the lid to the casing. CONSTITUTION:A lid 3 is dropped into the upper opening of a gas filter casing and engaged with a sealing member on the inner periphery of the opening. Two flanges 4 and 4' are inserted into groove 8 on the inner periphery of the casing slightly above the engaging part, a shaft 5 provided at the center is rotated to detach the lid 1 and fixed, and the casing is usually covered with a protective cover. The lid is opened and closed in this way by rotating the shaft.
