摘要： PURPOSE:To keep a good contact even with a curved-surface-shaped object to be measured by bringing a flexible belt-shaped temperature sensor cable wherein a pair of detecting lines are embedded on both sides of a belt-shaped resistor layer into contact with the object to be measured, cutting one of the pair of the detecting lines in a plurality of positions and measuring the resistances between cut detecting line segments. CONSTITUTION:In a condition that a belt-shaped temperature sensor cable 2 is open-spiralwise wound around the surface of an object 1 to be measured, one of two detecting lines 4 is cut, for example, for one winding pitch P of the belt-shaped temperature sensor cable 2 and a belt-shaped resistor layer 3 is cut at breaks 9 to a plurality of portions [(N+1) portions if the number of the breaks 9 is N] (a), (b), (c) and (d). Lead wires 8 are connected to cut detecting line segments 4 and the resistance values (resistance in the width direction of the temperature sensor cable 2) between the adjacent cut detecting line segments 4 and 4 at a plurality of portions (a), (b), (c) and (d) are measured by a resistance measuring instrument 10 constituting a bridge circuit. Further, the resistance values are converted to temperatures values by a resistance-to- temperature converter 11 to be displayed on a display 12.

摘要： PURPOSE:To alleviate interference between building work and main line laying work by unfastening a main line compression terminal and a branch unit at a branch when the power capacity of main line power cable or a branch wiring is increased and replacing with a desired power cable or a branch cable. CONSTITUTION:A power cable 1 has such structure as a main line compression terminal 11 and a branch unit 13 can be unfastened. When it is required to replace the power cable 1 with one having higher capacity due to increase of power capacity in the building or on the floor, a fastener 14 is loosened to unfasten the main line compression terminal 11 and the branch unit 13 and then the main line compression terminal 11 is fixed to the end of a power cable 1 having desired high capacity. Since the main line can be laid after completion of wiring shaft in a building by suspending the power cable or the branch part, interference between building work and main line laying work is alleviated resulting in shortening and simplification of work schedule.

摘要： PURPOSE:To prevent corrosion and deterioration of a stainless steel pipe due to entry of moisture in the ground and underground water into a gas pipe by mounting a water-tight layer which is made of synthetic resin and has rubber elasticity on the surface of stainless steel pipe. CONSTITUTION:A stainless steel pipe 1 is made like bellows and spiral corrugation and provided with flexibility. Further, a water-tight layer 2 which is made of synthetic resin and has rubber elasticity is mounted on the stainless steel pipe 1 to prevent entry of moisture in the ground and water on the ground into a gas pipe which is imbedded in the ground and prevent corrosion and deterioration of the stainless steel pipe 1 due to water. Consequently, gas does not leak, and sufficient reliability is obtained even when the gas pipe is used for a long time. Thus formed water-tight layer 2 is covered by a plastic sheath 3 to obtain desired gas pipe.

摘要： PROBLEM TO BE SOLVED: To provide a semi-conductive watertight composition which can be filled between conductive wire elements by means of an extrusion coating method applied to a twisted conductor and can form a semi-conductive layer or an inner semi-conductive layer at the same time during filling and to provide an insulated electric wire in which the semi-conductive watertight composition is filled between the conductive wire elements and the conductor is covered with the composition. SOLUTION: The twisted conductor 1 is extrusion-coated with the semi-conductive watertight composition and is filled in interstices between the conductive wire elements 1 to form a watertight layer 2. At the same time, the composition covers the outer circumferential surface of the conductor 1 to form a semi-conductive layer 3. The semi-conductive watertight composition comprises 100 pts.wt. of a base polymer containing a crosslinkable polyethylene, 1 to 20 pts.wt. of a water absorptive polymer, 40 to 80 pts.wt. of acetylene black or furnace black or 5 to 50 pts.wt. of Ketjen black as carbon black each as an essential component.

摘要： PURPOSE:To suppress an increase in height of a wiring and to enhance versatility at the time of increasing power sources by laying a plurality of electric cables connected at a power supply side to a distribution board and extended in a state aligned horizontally from the board to positions in a room in a horizontally aligned state. CONSTITUTION:Table taps 15 are connected from a hollow part 3 to a plug socket 6 to be erected on a floor when an electric device 2 such as an OA device, etc., is connected to the socket 6 of the part 3 if the socket 6 is arranged by the socket with a cable of a building floor 1. That is, a plug 15a is inserted into an insertion hole 13a opened at a floor panel 13 and a flooring 14 or a gap of the panel 13, and connected to one of plug receptacles 6a, 6b, 6c. Removal of the plug 15a is prevented by inserting the plug 15a to the receptacles 6a, 6b, 6c and twisting it at the time of connecting.
