  • Patent number: 8462885
    Abstract: A voltage-controlled oscillator generates a first signal and a second signal having a phase reverse to that of the first signal. A switch supplies a current signal generated by a first charge pump to a loop filter. A counter counts a cycle number of the second signal included in one cycle period of a reference signal. A second charge pump supplies, to the loop filter, a first current signal having a constant value and a second current signal having a constant value whose polarity is reverse to that of the first current signal. The control circuit controls the switch and the second charge pump based on a comparison between the cycle number of the second signal counted by the counter and a value X.

  • Patent number: 7850469
    Abstract: Male and female connectors (10, 50) include male and female housings (11, 51) with accommodating portions (25, 61) that have rear end insertion openings for accommodating dummy connectors (30, 70). The dummy connectors (30, 70) include protrusions (37, 78) that interfere with the opening edges of the accommodating portions (25, 61) and prevent insertion if the dummy connectors (30, 70) are reversed forward/backward. However, properly oriented dummy connectors (30, 70) can be inserted into the accommodating portions (25, 61) while leaving the protrusions (37, 70) projecting out from the insertion openings.
