摘要： The present invention provides a charge pump circuit capable of achieving desired boosting operation even when a high-side switch for precharge or a low-side switch for driving output is constructed by a low-withstand-voltage transistor.The high level of a drive input signal for driving a high-side switch for precharge and a low-side switch for driving output in response to a clock signal is set to the level of a boosted output voltage. The low level of the drive input signal is set to the level of an input voltage, not ground potential.

摘要： A resin-made air cleaner includes a hollow resin-made housing, a tubular element accommodated in the housing, a tubular projection, a gasket fitted around the tubular projection, and disposed between the tubular element and the tubular projection, a stopper for inhibiting the gasket from moving. The tubular projection is disposed on at least one of opposite end surfaces of the housing so as to project toward the inside of the housing. The stopper is disposed on the projection and/or the opposite end surfaces of the housing, on which the projection is disposed. This arrangement not only enables the increase of the resin content of the air cleaner, but also inhibits the gasket from coming off from the projection when the element is disassembled.

摘要： A comparator compares phases of an input data supplied from an input terminal and a synchronizing clock signal output by a variable counter, and outputting a comparison result signal indicative of any of a "lead", a "lag" and a "non-detection" of the edge of the input data with respect to the up edge of the synchronizing clock signal. A state detector circuit detects the numbers of "leads" and "lags" in comparison result signals output by the comparator, and outputting a state detected signal indicative of any of "the number of leads is larger", "the number of lags is larger" and "the number of leads is equal to the number of lags". A dividing ratio selection circuit outputs a dividing ratio signal indicative of any of a "dividing ratio smaller than a reference dividing ratio", a "dividing ratio greater than the reference dividing ratio" and the "reference dividing ratio", based on the comparison result signals output by the comparator and state detected signals output by the state detector circuit. A variable counter divides the frequency of a reference clock signal in response to the dividing ratio signal output by the dividing ratio selection circuit and outputs the result of the division to the comparator and an output terminal.
