摘要： PURPOSE:To prevent the peeling-off of an electrically insulating synthetic resin film from a flat cable or remarakable deterioration of insulating performance even if a bending portion is formed on the flat cable. CONSTITUTION:A conductor for a circuit pattern is held between insulating layers via an adhesive layer made of a water resistant denaturated polyolefin adhesive and/or a water resistant saturated copolymer polyester adhesive, and further, is provided with at least one bending portion. Even if a flat cable is soaked in water or used under high temperatures in the high humid atmosphere, it is possible to prevent water absorption or hydrolysis due to water absorption in the adhesive.

摘要： PURPOSE:To obtain a thin wideband radiowave absorber, by bonding a mat-like fiber aggregate wherein a magnetic powder is stuck on fibers directly or indirectly to a sintered magnetic substance tile. CONSTITUTION:A wideband radiowave absorber D is so created that a mat-like fiber aggregate 3 wherein a magnetic powder 5 is stuck on fibers 6 is bonded to a tile 2, e.g. a sintered magnetic substance tile 2 by a bonding agent, e.g. an epoxide based, isocyanate based, cyanoacrylate based bonding agent or the like. Especially, the epoxide based bonding agent is preferred because the irregular surface of the mat-like fiber aggregate 3 can be well bonded to the tile 2 with this agent and the bonded part can be stabilized for a long time. Since according to this configuration, the mat-like fiber aggregate including magnetic-powder-stuck fibers is formed on the sintered magnetic substance tile, the thickness of the whole of the radiowave absorber can be made small, e.g. to be about 60mm, in comparison with a conventional pyramid type or pyramid-single layer type composite radiowave absorber.

摘要： PURPOSE:To use a low-priced of rat preventive agent by including at least one sort of rat preventive agent selected from a microcapsuled terpenoid, a terpenoid included in a porous substance, and a terpenoid included in a host compound. CONSTITUTION:On a conductor core 11, a layer 12 which has three functions as an insulator, a sheath, and a rat prevention is provided, and the layer 12 is composed of an insulator, a sheath material, and a rat preventive agent. The rat preventive agent includes at least one sort selected from a microcapsuled terpenoid, a terpenoid included in a porous substance, and a terpenoid included in a host compound. Since the cost of the terpenoid is cheaper than the conventional rat preventive agent, cycloheximide, the cost of a rat injury preventive cable can be reduced.

摘要： PURPOSE:To obtain the subject tube with excellent heat resistance, chemical resistance and flexibility by molding a material wherein a fluorinated graft copolymer is a main component into a tube and expanding it after crosslinking. CONSTITUTION:A heat-shrinkable tube is prepd. by molding a material wherein a fluorinated graft copolymer (e.g. a graft copolymer prepd. by graft- copolymerizing vinylidene fluoride onto a vinylidene fluoride-hexafluoropropylene copolymer rubber) is a main component into a tube and expanding it after crosslinking (e.g. radiation crosslinking in the presence of a crosslinking auxiliary such as triallyl cyanurate). A heat-shrinkage tube with excellent flexibility and high performance is obtd. without any bad influence to the heat resistance and chem. resistance inherent in the fluorinated graft copolymers.
