Abstract: In a line guiding device for receiving and guiding energy lines, which can be arranged to form at least one loop which includes two runs and a connecting region connecting same, there is provided a device which causes a restoring force to be produced in the spread-open state of the runs in which the connecting region is bent open, the runs being moved back into their folded-together position by the restoring force.

Abstract: A first board includes a first ground plane, a first ground land, a first transmission line, and a first signal land connected to the first transmission line, wherein the first ground land and the first signal land are formed on the same surface. A second board includes a second ground plane, a second ground land, a second transmission line, and a second signal land connected to the second transmission line, wherein the second ground land and the second signal land are formed on a surface opposing the first board. The second ground land and the second signal land oppose the first ground land and the first signal land, respectively. A conduction member connects the first ground land and the second ground land. The first signal land and the second signal land are connected by capacitance coupling without using any conductor.

Abstract: A cable assembly extends in a longitudinal direction. The cable assembly comprises a first cable, two second cables, two coupling portions, an interposing portion and an outer cover. The first cable has a first conductor and a first cover. Each of the second cables has a second conductor and a second cover. The coupling portions couple the second covers, respectively, with the first cover. The first cable, the two second cables and the two coupling portions are arranged in a V-shape in a plane perpendicular to the longitudinal direction. The interposing portion extends along the first cable and the two second cables and has a full length which is equal to that of each of the first cable and the two second cables. The interposing portion is brought into contact with all the first cable and the two second cables.
