    摘要： Optimum signal/power transmission characteristics are realized in a cable containing a plurality of individually insulated conductors which vary in size one to another wherein the ratio of the size of one conductor to the next larger conductor is about 0.62. Normally, at least three different sizes of conductors will be employed in a cable wherein each size classification differs from the next larger or smaller size classification by the specified ratio. This particular ratio is often called the golden section and is the ratio between the two sizes in which the lesser of the two is to the greater as the greater is to the sum of both.

    摘要： An improved, highly flexible flat multi-conductor electrical cable is provided, useful for example in robots wherein such cables may be flexed many times, comprising a plurality of conductor assemblies held in parallel relationship between layers of insulating coverings, the improvement comprising conductor assemblies having an elongate, non-conductive center core filament helically overwrapped along its longitudinal dimension by a first conductor in foil or tape form, such as copper foil, this first tape conductor having an outer covering of a conductive, low-friction material, the conductive covering being helically overwrapped along its longitudinal dimension by a second conductor in foil or tape form, such as copper foil, the second foil conductor being wrapped in a lay opposite to that of the first conductor, i.e. if one foil conductor is "S" wrapped, the other foil conductor is "Z" wrapped. A preferred core filament material is expanded, porous, sintered polytetrafluoroethylene, and a preferred conductive covering is conductive, unsintered polytetrafluoroethylene. Preferred insulating coverings are layers of polytetrafluoroethylene.

    摘要： High frequency electrical cable is provided in accordance with the teachings of the instant invention wherein a plurality of conductors for transmitting information are contained in a common sheathing. Each of the plurality of conductors takes the form of a central core of insulating material upon which a layer of conductive material is rigidly disposed. The thickness of the layer of conductive material is such that current penetration is substantially independent of frequency within a given frequency range. Therefore, within this frequency range the attenuation characteristics of the resulting cable are substantially independent of frequency.
