An interconnect element incorporates a plurality of smaller, substantially identical, interconnect modules. This enables an improvement in stiffness of the vehicle body against side impact efficiently by a simple reinforcing structure. A core segment is inserted into the open end of the guide wire, and serves as a piston to inflate the balloon after saline is introduced into the lumen. The Ni-based forged alloy exhibiting a \u03b3\u2032-phase dissolution temperature of from 920 to 970\xb0 C. In another embodiment of the invention, a cable televison amplifier is provided with a male F-59 type connector for direct connection to the female input port of a typical splitter.
