  • Patent number: 4783366
    Abstract: This invention concerns a shock absorbing material placed between two objects for buffering the shocks, and a method of applying the same.Heretofore, a previously formed shock absorbing material is bonded by way of an adhesive or the like to an object to be buffered. However, there has been a disadvantage that no desired bonding strength can be obtained or the adhesive is degraded. It is intended in this invention to render the shock absorbing material fusible under heating, by which the shock absorbing material is fused due to the melting of the shock absorbing material itself with an object to be buffered using no adhesive thereby increasing the bonding area and improving the bonding strength as compared with the conventional case.

  • Patent number: 4708351
    Abstract: A sealing layer that seals the gap between the body or window glass and the weatherstrip attached to the door, window, trunk, roof side, etc. of an automobile, and also to a weatherstrip, automotive body, and glass plate provided with said sealing layer. The water-absorbing material swells upon absorption of water, sealing the fitting part of the weatherstrip. The water-absorbing material is made of a mixture of a water-absorbing polymer and rubber or synthetic resin. The sealing layer is formed on the fitting part of the weatherstrip, body, or window glass at which the weatherstrip is fitted to the automotive body or the window glass is fitted to the weatherstrip.

  • Patent number: 4559252
    Abstract: A reinforcing combination is useful to reinforce plate metal which comprises a pressure-sensitive adhesive sheet formed from a sheet-like substrate comprising asphalt, rubber, and a filler and having a pressure-sensitive adhesive layer on one surface thereof; and a thermosetting sheet formed from a sheet-like substrate comprising polyvinyl acetal, monomeric diallyl phthalate, a filler, and at least one additive, and having a reinforcing fiber layer on one surface and a pressure-sensitive adhesive layer on the other surface thereof; wherein said thermosetting sheet at one edge partially overlaps said pressure-sensitive adhesive sheet with the pressure-sensitive adhesive layer of the former in contact with that surface of the latter which is remote from its own pressure-sensitive adhesive layer. A reinforcement configuration is provided by attaching the components of the reinforcing combination in assembly or separately followed by heat curing.
