摘要： PROBLEM TO BE SOLVED: To provide a blocking device for an unused supply pipe capable of easily and quickly executing the blocking work of the unused supply pipe in blocking the unused supply pipe in a road excavated state. SOLUTION: A blocking member B is composed of an elastically deformable seal member 1 having a diameter slightly smaller than an inner diameter of the unused supply pipe A, first and second holding members 2, 3 for allowing the seal member to be swelled and deformed in the circumferential direction to be closely abutted on an inner peripheral face of the unused supply pipe, and a disc-shaped leakage prevention disc 4 concentrically mounted on both sides or one side of the seal member, made of a single foam sponge material of a hardness (Hvs) of 15-35, and having a diameter slightly larger than the inner diameter of the unused supply pipe, a feeding rod for feeding the closing member into an inner depth of the unused supply pipe is composed of an engagement groove 71, a stopper cylinder 76, a first feeding rod 7 and a second feeding rod 8.

摘要： PROBLEM TO BE SOLVED: To gather metal cutting chips nearly completely and remove them. SOLUTION: This device is provided with a scraper sleeve 21 which has a shape allowing an attraction body 28 to be inserted into guide pipes 18 continuously provided on an auxiliary pipe 17 facing to a connection pipe 2, and wherein the tip section is made from an edge section 21b with which the outer peripheral face of the attraction body 28 can contact closely. In such constitution, the metal cutting chips attracted to a permanent magnet 30 are squeezed by drawing the attraction body 28 into the sleeve 21.

摘要： PROBLEM TO BE SOLVED: To correspond with two kinds of large and small gas meters different in the interval of connection openings by forming the side of a joint attaching part provided on a bracket so that the interval of the gas meter connection openings of right and left joints can be modified. SOLUTION: A pair of right and left recess hole-like joint attaching part 13 opened toward a front face is provided on a bracket 1 horizontally attached to the wall C of a building. The outward side 13c of the attaching part 13 is vertically formed to the face of the bracket 1, and the opening face of an inside face 13d is inclined to the face of the bracket 1. The attaching part 13 is formed as a whole so that the lateral width of the opening side is widened, and a joint 2 is pivoted so as to be projected from the face of the bracket. Thereby when the right and left joints 2 are set along the outside face 13c of the attaching part 13 respectively, they are mutually parallel, and correspond to the interval of the inlet 5 and the outlet 6 of a large-sized gas meter B. In addition, when the joint 2 is set along the inside face 13d, the edges of both the joints 2 approach and can correspond to the interval of the connection opening of a small-sized gas meter.

摘要： PROBLEM TO BE SOLVED: To quickly and easily repair a pipe or a wire from an outer surface thereof without using a special tool by covering a sheet formed with multiple block structure for securing rigidity and having a function as a cushion material over the whole surface of the pipe or the wire from the outer surface thereof, and press adhering them. SOLUTION: A adhesive 1 is applied over the whole surface of one surface of a sheet main body A, and a protecting film 3 for covering the adhesive is attached to the coated surface freely to be peeled. A surface of the sheet main body A opposite to the surface coated with the adhesive 1 is provided with multiple block structures 2 so that the bloc structures are projected over the whole surface. A groove 4 is provided between each block structure 2. This groove 4 has a width at a degree capable of housing a blade such as a cutter. In the case of repairing a pipe B, the sheet main body A is cut into the required shape and dimension, and the protecting film 3 is peeled so as to expose the adhesive 1. The sheet main body A is fitted on a part to be repaired, and press adhered so as to cover the damaged part with the sheet main body A and so as to seal the damaged hole 5.
