Abstract: In a cord equipped with a connector, a metal or synthetic resin tube has at one end a connecting ring and in its wall a through-hole communicating with a hollow of the tube. End portions of a cord are inserted in a trued-up form in the hollow from an opening of the connector. The hollow and the through-hole are filled with a molded core insertion-molded of synthetic resin so that the molded core is prevented from accidental removal from the hollow, thus firmly holding the end portions of the cord. This connector-equipped cord is particularly useful when applied to a pull string of a second bag or a slider pull tab of a slide fastener.

Abstract: A design for a high damping composite joint which dissipates vibrations through the use of air gaps and viscoelastic material minimizing the transfer of vibrations to the metallic coupling. Viscoelastic material is used with adhesive to provide for increased energy dissipation by the joint. As the load increases on the joint, the load transfers from adhesive to the viscoelastic. The viscoelastic begins to take the load of the joint at the point where the adhesive becomes plastic. Acoustic vibrations are then dissipated in the viscoelastic and are prevented from being transferred to the metallic coupling by air gaps provided in the joint. The amount of viscoelastic and adhesive used depends on the anticipated load. Finite element analysis is used to calculate optimal amounts of viscoelastic and adhesive.
