摘要： PURPOSE:To cause the fitting operation of structural member to be easily achieved by inserting it into a narrow part by fitting the surface layer composed of the copolymer capable of follow-up deforming onto at least a part of the surface of the base plate formed with shape-memorizable thermosetting resin. CONSTITUTION:The sealing member 4 keeping the sealing condition between the plate members 2, 2 composed of gloss, etc., is composed of the base plate 6 formed with the shape-memorizable thermosetting resin in which almost H shape in cross section is stored and the surface layer 8 composed of the elastic copolymer formed on its outer peripheral whole surface. When external force is applied at the temperature equal to or higher than the thermal deformation temperature of the base plate 6 thereto, since a holding space 10 is expanded and deformed, in this state the end edge of the plate member 2 is inserted into the holding space 10. When the base plate 6 is heated at least restoring temperature (the temperature at which said plate is restored to original shape without applying external force, and normally it is rather higher than the temperature of thermal deformation), the base plate 6 is restored to almost H shape, and the plate member 2 is held by narrowing the holding space 10. Thus, fitting operation may be remarkably easily achieved.

摘要： PURPOSE:To confirm simply and accurately the molten state of a fusion welded layer by boring a blind hole starting from the surface of a base of an electrofusion joint through the fusion welded layer, bringing the end of a probe into contact with a bottom section of the blind hole and displace the probe following the melting of the bottom section of the blind hole. CONSTITUTION:A fusion welded layer 2 including a heat developing means is disposed on a base 1 of an electrofusion joint. For the purpose of confirming the molten state of the fusion welded layer 4, a blind hole 6 starting from the surface of the base 1 and reaching the fusion welded layer 2 is bored. A melt confirming sensor 20 is provided. A pawl 26 of the melt confirming sensor 20 comes off one of the tooth 25 and a probe 21 in the state that the probe 21 is protruded longest is inserted into the blind hole 6. When the fusion welded layer 2 is heat developed by the heat developing means, the bottom section of the blind hole 6 is softened and the end of the probe 21 is collapsed into the bottom of the blind hole 6 to displace the probe 21. To avoid the displacement, respective electric contacts 28a and 28b are opened and closed by a stopper 21a provided at the rear end of the probe 21. The molten state of the fusion welded layer 2 is confirmed simply and accurately by the arrangement.
