摘要： PROBLEM TO BE SOLVED: To make precision of a cut length of a heating wire unnecessary while it can be easily changed to be strung by a method wherein a plurality of chuck pieces are provided inside a sleeve moving with engagement of a screw thread, and a support block is, in a free advance and retreat manner, fitted to a specific position. SOLUTION: One end of a heating wire cut out by an appropriate length is fixed to one side edge of a seal stand. A support block 6 is advanced, and the other end of the heating wire is inserted into a chuck mechanism. By retreating a sleeve 52 on a terminal main body 51 by rotating a sleeve 52, a chuck piece 53 is fastened, held, and the support block is retreated. Thereafter, a suitable tension is always applied to the heating wire with repulsive force of a spring or air pressure of an air cylinder, and a slack is prevented. Since executing holding in of the heating wire after advancing a movable terminal part to a suitable position in holding the chuck mechanism of the heating wire, the heating wire can be easily fitted even by an operator of weak force.

摘要： PURPOSE: To realize coupling of large-diameter pipes by forming a coupler having an open-end hollow body of a non-conductive crosslinked polyolefin material to allow the couple to have a first minimum inner diameter before heating and a second minimum inner diameter smaller than the first inner minimum diameter after heating. CONSTITUTION: A coupler 10 is made of a polyolefin, for example, polypropylene, polybutylene or the like. The coupler 10 and polyethylene pipes 12, 14 arranged by matching their ends to be bonded integrally with each are assembled, and a heating element 18 is wound in a slot in a saw-tooth outer surface of the coupler 10. A gap 22 exists between an outer surface of the pipe 14 and the minimum inner diameter of the coupler 10 having an inner thread 20. Heating is carried out with the heating element 18, and outer surface temperatures of the coupler 10 and one of the pipes 12, 14 are monitored. The coupler 10 contracts above the pipes 12, 14, and the saw-tooth inner surface of the coupler 10 bites into the outer surfaces of the pipes 12, 14 and mechanically locked with bonding surfaces.

摘要： PURPOSE:To obtain stable adherence at a time of resin adhering by a method wherein a controlling means interrupts power source supply to a bonding means based on a heating finish output from a first comparing means and a resetting means resets the bonding means to its initial state based on an output from a second comparing means. CONSTITUTION:When a heater 7 is heated and a temperature signal of a thermocouple 22 is outputted through an amplifying IC 25 to a comparator 28, the comparator 28 compares a cooling finish reference voltage inputted from a variable resistance 33 with a voltage outputted from the amplifying IC 25, and at a time when the latter becomes higher than the former, a high level signal is outputted to an input terminal b2 of a NOR-gate 20, whereby an output terminal b3 of the NOR-gate 20 becomes low level. By this, a transistor 12 of a power supplying means 13 turns OFF and a double-directioned thyristor 5 also turns OFF, whereby power supply to the heater 7 is interrupted.
