Abstract: 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.

Abstract: A signal address arithmetic circuit is used for performing address arithmetic required for executing such analog signal algorithms as adaptive predicative coding, adaptive bit allocation in predictive coding, adaptive transform coding, etc. The address arithmetic circuit is constructed of two counters, three registers, two selectors, a shift circuit an adder and AND gate circuits. The first selector selects either one of the first counter, the second counter or a first register, and its output is applied to one input terminal of the adder. The second selector selects either one of the second counter or the third register and its output is directly applied to the other input of the adder. The output of the adder and the content of the second register for each bit are applied to the AND gate circuits and its output is set in the third register, the content thereof being used for memory addressing.

Abstract: 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.
