摘要： A plastic pipe (10) includes a pipe main body (12), and, at the end portion of the pipe main body (12), there is formed a receiving opening having an enlarged diameter, which is provided in the inner surface or in the vicinity of the inner surface thereof with a heating unit (18). At the time of jointing, the outer peripheral surface of the pipe end portion of a pipe (28) and the like to be jointed is machined by a scraper or the like, and the machined portion is inserted into the receiving opening. Then, electric current is supplied to the heating unit (18) to heat the same. Then, the joint surfaces of the pipe (28) and the like to be jointed and the receiving opening and synthetic resin disposed thereabout are melted, so that the both members are welded together.

摘要： PURPOSE:To automatically set an output and a conducting time and to improve reliability of operability and connecting operation by stopping conduction of a work coil from a high frequency power source after a prescribed time is elapsed from a time when a temperature of a magnetic alloy heater reaches a Curie point. CONSTITUTION:A high frequency output is applied from a high frequency power source 14 to a magnetic alloy heater 64 provided at a connecting part through a work coil 12. In this case, a prescribed time responsive to a type of a joint 66 is previously set at each joint. The source 14 is connected to the coil 12, and the type of the joint 66 is recognized. Then, conduction of the coil 12 from the source 14 is started. Whether a temperature of the heater 64 reaches a Curie point or not is judged, and after a prescribed time elapses after the temperature of the heater 64 reaches the point, conduction of the coil 12 from the source 14 is stopped.

摘要： PURPOSE:To simply realize optimum heating at a low cost by a method wherein solid or hollow bar-shaped heat-resisting elastic body, the outer diameter of which is smaller than the inner diameter of a thermoplastic resin pipe, and magnetic alloy layer, which is formed on the outer surface of the heat-resisting elastic body and has the predetermined Curie temperature, are provided. CONSTITUTION:The heater concerned contains a solid bar-shaped heat-resisting elastic body 12, which is made of fluorine-based synthetic rubber or the like and the outer diameter of which is slightly smaller than the inner diameter of a pipe 16 to be bent. Further, on the outer surface of the heat-resisting elastic body 12, band-shaped or wire-shaped magnetic alloy layer 14 having the predetermined Curie temperature is spirally formed. The Curie temperature of the magnetic alloy layer 14 can be controlled by changing the mixing ratio of respective constituents so as to coincide with the optimum temperature at the bending of the pipe 16. Thus, pipe can be simply heated at the optimum temperature without troublesome temperature management and control.

摘要： PROBLEM TO BE SOLVED: To shorten fusion working time for improved workability. SOLUTION: When a work coil 10 is disposed around a joint 12 and highfrequency current is applied to a conductive wire 30 from a high-frequency power source 42, magnetic flux density working upon a heater 22 decreases in a part corresponding to the section where the conductive wire 30 is wound roughly, so that the heating value of the heater 22 decreases. In a part where the heating value of the heater 22 in the joint 12 decreases, resin is fused only in a very narrow area round the heater 22, therefore, hardened earlier than the other parts. It is thus possible to function this part as a clamp until the other parts have been hardened.

摘要： PURPOSE:To obtain an electric welding joint having a simple structure and easy in execution by forming the acting part acting on a plurality of the switch elements provided to a connector to a socket and providing the positioning means of the connector and the socket. CONSTITUTION:When the upper part of the fixing member 48 of a connector 28 is pressed, the lower end part thereof is opened outwardly and the fixing member 48 is slid downwardly along a notch 22 to insert the terminal cover 88 of the connector 28 in the hollow part of a socket 16 and a terminal 26 is inserted in the recessed part 106 of a terminal 102. An engaging piece 52 is engaged with the under surface of the flange part 20 of the socket 16 to fix the connector 28 and the projection 24 of the socket 16 presses a piezoelectric switch 78. The signal from the piezoelectric switch 78 is inputted to a microcomputer through an electric wire 74. The microcomputer determines the current supply time of a current on the basis of the signal from the connector 28 to transmit a signal to a power supply. A current is supplied to an electric heating line 14 from the power supply for the desired time corresponding to the kind of an electric welding joint 10 through the connector 28 and the terminal 26.

摘要： PROBLEM TO BE SOLVED: To enable highly reliable fusion bonding even under environment of a cold district by always setting the internal temp. of a fusion power supply apparatus to a specified. (recommendation operation) temp. range. SOLUTION: A heater 36 is arranged in a fusion power supply apparatus 10 along a casing 40 and connected to thermostats 38a, 38b to control the supply of a current to the heater 36 by the thermostats. That is, the temp. in the fusion power supply apparatus 10 is predetermined temp. or lower, the supply of a current to a liquid crystal display part or a power supply part is stopped while the supply of a current to the heater 36 is started to raise the temp. in the fusion power supply apparatus 10. When the internal temp. reaches the specified temp. by the heater 36, the supply of a current to the heater 36 is stopped and power is supplied to the power supply part.

CONSTITUTION:A spherical valve body 1 with substantially the same outer diameter as a pipe inner diameter and having a through hole 1A provided in the orthogonal direction to a rotating shaft Q is supported in a pipeline P in accord with the rotating shaft Q in the diameter direction of the pipeline P, and a pressure receiving plate 2 having a through hole 2A concentric with the pipeline P provided on the upper stream side along the axial line of the pipeline P is fitted to a guide channel 3 formed on the pipeline P inner surface and supported to the valve body 1 in such a manner as to be movable in the pipe axial direction. Arms 4, 4, having rack teeth 4A are integrally mounted on the pressure receiving plate 2, and the teeth 4A are engaged with pinion gears 1B, 1B mounted on the upper and lower ends of the valve body 1, whereby an excess outflow preventing valve is constituted. When an excess outflow occurs in the pipe, the pressure receiving plate 2 is moved in the lower stream side, and the valve body 1 is rotated by this moving force to intercept the passage.

摘要： PROBLEM TO BE SOLVED: To excellently fuse a junction face of both tubes by making a conductive coil of a work oil correspond to a magnetic heater of a radially expansive socket when the work coil is arranged on the periphery of the radially expansive socket by inserting the other tube end part into a radially expansive socket of one tube end part. SOLUTION: The tube end of a tube 14 (polyolefin resin) is inserted into a radially expansive socket 20 in which a basket-shaped magnetic alloy heater 18 on the tube end of a tube 12 (polyolefin resin) is embedded. A work coil 10 for induction fusion having a coil 28 round which a conductive electric wire is wound, is arranged on the periphery of this radially expansive socket 20, and its contact part 36 is brought into contact with the tip A of the socket 20, and a contact part 48 is brought into contact with a radially expansive step part B. When a high frequency current is given to the coil 28 from a high frequency power source, induction electric power is given to the heater 18, and it is heated, and the tubes 12 and 14 are fused on each other. At this time, a wing bolt of the work coil 10 is loosened, and when the contact part 36 is moved, even if the work coil 10 is arranged even in any direction, the coil 28 can be made to correspond to the whole heater 18.

摘要： PROBLEM TO BE SOLVED: To enhance an execution property by enabling the time required for fusing work to be greatly reduced. SOLUTION: In a second part where a second heater 18b with a lower Curie temperature is placed, a resin is melted at lower temperatures than in a first part where a first heater 18a is placed, and hence cures faster than in the first part. Thus, after the resin in the second part has cured, this part functions as a clamp, making it possible to remove a clamp member 20 even before the resin in the first part has cured.
