In a semiconductor integrated circuit device, the ground source electrode lines of logic and memory circuits are kept at a ground potential in an active mode, and are kept at a voltage higher than the ground potential in an unselected standby mode. Each of the stretchable members includes a first block, a second block and two joint units. A fixing element is inserted into the axial bore, an outer diameter of the fixing element being greater than the smallest inner diameter of the bore. A shaft communicates with the sun gear of the third planetary set and to the housing. The device comprises a pin, socket or lug and a means for electrically connecting the pin, socket or lug to groups of strands of an individual multi-bunch core of a machine, reeling or trailing cable.
