  • Phase locked loop with phase shifted input
    Patent number: 7636018
    Abstract: In a phase locked loop (PLL), phase shifters shift a phase of an input signal. Based on the phases of the input signal, the shifted signals, and a frequency division output signal, phase frequency detectors (PFDs) generate phase difference signals. In response to the phase difference signals, charge pumps (CPs) control output voltages thereof. Based on the output voltages of the CPs, a voltage controlled oscillator (VCO) outputs an output signal. A frequency divider divides the frequency of the output signal from the VCO to generate the frequency division output signal. A circulator outputs the frequency division output signal to one of the PFDs at a proper timing. A modulator reduces quantization errors of the frequency divider.

  • Bearing structure
    Publication number: 20090087129
    Abstract: The present invention relates to a bearing structure having a top end face, a bottom end face, and a bore communicating with the top and bottom end faces, and having at least two oil-guide channel disposed on the inner wall of the bore, extending axially and penetrating one of the same end faces of the bearing. When the present invention is applied to a motor structure, the oil-guide channel is upwardly or downwardly disposed by penetrating the top or bottom end face of the bearing. Hence, when lubricant is churned by the spindle to permeate and diffuse, the oil-guide channel can block and collect the rising lubricant for the bearing to absorb, circulate and reuse again in a timely manner, thereby effectively preventing lubricant from draining and prolonging the operational lifespan of a motor.
