摘要： An insulator may include a first insulator portion that is structurally configured to receive a portion of a center conductor portion of a coaxial cable extender and a second insulator portion that is structurally configured to receive at least a portion of the first insulator portion. The second insulator portion may comprise a higher dielectric constant than a dielectric constant of the first insulator portion such that the insulator may be structurally configured to enhance electrical performance of the coaxial cable extender.

摘要： A method of enhancing surface electrical conductivity of an article formed of a conductive polymer material, such as a conductive polymer film, includes the step of providing an article formed of a conductive polymer . The conductive polymer is made up of a dielectric polymeric material and conductive fibers. A desired pressure is applied to at least a portion of the article while simultaneously heating at least a portion of the article to a desired temperature. The desired pressure and the desired temperature are maintained on at least a portion of the article for a desired time period. This method reduces a polymer-rich skin layer on the surface of the conductive polymer material and helps to randomize the orientation of the conductive fibers on the surface.

摘要： A shielded cable comprising two insulated wire covered with first and second metal clad resin tapes each of which has a laminated metal layer and a resin layer. The first metal clad resin tape covers the circumference of the two insulated wires by open-wrapping and the second metal clad resin tape is spirally wrapped around the circumference of the first metal clad resin tape. The first and second metal clad resin tapes are disposed while the metal layers face each other and, in the portion where the second metal clad resin tape is overlapped by wrapping, the metal layer of the overlapped one second metal clad resin tape and the metal layer of the other second metal clad resin tape are in contact with the first metal clad resin tape. The shielded cable can prevent sharp signal attenuation in a high frequency region and is easy to bend and flexible.
