    摘要: An overhead cable includes an outermost surface formed by twisting together a plurality of segment strands. A plurality of spiral grooves form recesses having substantially rectangular cross-sections and are provided at intervals in a circumferential direction of either the outer surface of the segment strands or the outer surface regions of boundary portions where twisted segment strands adjoin each other. Thin segment strands and at least one thick segment strand form the outermost layer. A recessed portion is provided at one side surface among two surfaces of the segment strands forming the outermost layer, a projecting portion is provided at the other side surface, and the strands are twisted together so that the recessed portions and the projecting portions mate. The recessed and projecting portions formed at the two side surfaces of the segment strands mate with each other to form recess-projection mating portions, and the lengths of the contact of the recessed and projecting surfaces at the recess-projection mating portions is configured to be no more than 10% of the length of the recess-projection mating portions.

    摘要: A phase-locked loop circuit provides a phase comparator which receives input signals through a first input terminal, a loop filter which receives a first output and a second output of the phase comparator, and a voltage-controlled oscillator which produces output signals of an oscillation frequency proportional to the first output and the second output of the loop filter. The signals corresponding to the output signals produced by the voltage-controlled oscillator are supplied to a second input terminal of the phase comparator so that the phase of the signals supplied to the first input terminal of the phase comparator is compared with the phase of the signals supplied to the second input terminal. In the present invention, the loop filter comprises a first capacitor connected to the output terminal of the loop filter, second and third capacitors, each having a terminal connected to the output terminal of the loop filter, and a charging circuit for electrically charging the first, second, and third capacitors. The charging circuit is connected in parallel with the second capacitor. A discharging circuit for discharging the first, second, and third capacitors is connected in parallel with the third capacitor.
