12. A cable system as recited in claim 11, wherein a jacket is applied over said twisted pairs of each of said first and second cables, and wherein a twisting of said jacket causes said helical twisting of said twisted pairs.
13. A cable system as recited in claim 11, wherein said predefined extent is at least one-quarter of the diameter of one of said twisted pairs.
14. A cable system as recited in claim 11, wherein said extension is integrally formed with said end of said one leg.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An injector for liquid medicines comprising:
a cylindrical body having an opening at each end thereof and provided with a fluid inlet and a fluid outlet forming side openings through opposite sides of the cylindrical body, axes of the side openings being substantially perpendicular to a longitudinal axis of the cylindrical body, said inlet and said outlet respectively communicating with a lumen of the cylindrical body, said inlet opening at a position closer to the distal end of the cylindrical body than where the fluid outlet opens; and
first and second gaskets fluid-tightly and slidably arranged in the lumen of said cylindrical body and adapted to be moved along an inner wall of said cylindrical body, said first and second gaskets being spaced from one another to form a fluid chamber between them, said fluid chamber being filled with a liquid medicine;
said first gasket being slidable from a first position where the fluid inlet and outlet are communicated with one another, to a distal end of the cylindrical body via a second position where said fluid chamber is prevented from fluid-communication with the fluid inlet but communicating with the fluid outlet to inject the liquid medicine in the fluid chamber through the fluid outlet.
2. The injector according to claim 1, wherein said first gasket has sealing portions adjacent to each end thereof and is provided with a flow path between the sealing portions to allow the fluid inlet of the cylindrical body to communicate with the fluid outlet through the flow path when said first gasket is present at the first position, wherein at least one of the proximal end of first gasket and the distal end of the second gasket is provided with a cylindrical protrusion having an outer diameter smaller than an inner diameter of the cylindrical body so that the first gasket andor second gasket allows the fluid inlet to communicate with the fluid outlet through an annular gap formed between the cylindrical body and the protrusion when the first gasket is moved to the distal end of cylindrical body.
3. The injector according to claim 2, wherein said flow path is a circumferential groove or channel formed between sealing portions.
4. The injector according to claim 2, wherein said flow path is a through-hole formed between sealing portions and passing through the gasket.
