摘要： A centrifugal fan has a circular main plate driven and rotated by a motor rotary shaft, a plurality of blades fixed to an outer circumferential portion of the main plate and spaced apart at predetermined intervals in a circumferential direction of the main plate, and a side plate attached to ends of the blades opposite to the main plate. An air inlet port is formed at the center of the side plate. The side plate inclines outward in centrifugal directions from the air inlet port and has an arcuate cross section with a predetermined radius of curvature. A dead water region reducing space is formed between the blades and the side plate. The dead water region reducing space forms a smooth flow between the two surfaces of each blade, bringing about desirable blade performance.

摘要： A delay element generates a delayed clock signal which transitions with a delay from a rising (or falling) of a reference clock signal by a delay amount determined based on an output of a loop filter. A signal generation circuit generates two signals which complementarily change according to rising and falling of the reference clock signal and a transition of the delayed clock signal. A charge pump circuit performs on the loop filter, according to these two signals, a push (or pull) operation during an interval extending from a rising (or falling) of the reference clock signal to the transition of the delayed clock signal and a pull (or push) operation during an interval extending from the transition of the delayed clock signal to a falling (or rising) of the reference clock signal.

摘要： The clock recovery circuit includes a first oscillator and an edge detector. The first oscillator generates a plurality of clocks having different phases and a predetermined frequency. The edge detector detects two clocks, among the plurality of clocks, between edges of which an input data signal has made a transition. The first oscillator includes a plurality of delay cells connected in a ring, and outputs of the plurality of delay cells are output as the plurality of clocks. Each of the plurality of delay cells selectively delays a first-delay added input data signal or the signal output from the preceding delay cell, and outputs the selected delayed signal. The edge detector controls one delay cell among the plurality of delay cells corresponding to the result of the detection, to delay and output the first-delay added input data signal.

摘要： In a receiver circuit that receives data and clock signals through the cables, the number of transitions of a signal obtained based on the data or clock signal is detected by a frequency detection circuit, and when the number of transitions is not more than a predetermined set value, a signal for resetting the operation of a serial-parallel converter circuit included in a data processing unit is output, so as to control the output of received data. Thus, disconnection of the cable can be detected with low power consumption without providing a pull-up resistor and pull-down resistor and noise resistance can be improved.
