    • [Problems] To provide an endless belt for power transmission capable of efficiently improving the yawing attitude of the elements in a variable pulley.[Means for Solving the Problems] This endless belt (40) for power transmission includes the elements (42) and an annular band-like member (46) for supporting the elements (42). The endless belt is winched between a pair of variable pulleys (20, 30). Groove parts (60) extending from the front surface of the belt in the forward movement direction to a predetermined position not reaching to the rear surface of the belt in the forward movement direction are formed in the side surfaces (42A) of the elements (42) contacting with the belt sliding surfaces (26, 36) of the variable pulleys (20, 30).

    • The present invention provides a spread spectrum type clock generation circuit whose EMI for peripheral equipment is reduced. The clock generation circuit comprises a phase-locked loop circuit and a clock modulation circuit. The clock modulation circuit comprises a ΔΣ modulator, to frequency-modulate an output clock by modulating the frequency division number of a frequency divider in the phase-locked loop circuit by a digital circuit, and further comprises a modulation pattern controller for distributing the peak of a triangular waveform which is a modulation waveform generated by a modulation pattern generator to change the amplitude and the period thereof, thereby making it possible to eliminate dullness and distortion of a modulation waveform in a modulating method using a conventional analog circuit and to obtain an output clock having higher modulation efficiency than that in a case where a normal triangular waveform is employed in a conventional modulating method using a digital circuit.
