    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: Provided is a DPF failure detection device not only capable of a quick detection but also having less erroneous and a small power consumption. The DPF failure detection device, after starting applying a dust collecting voltage to a dust collecting electrode, applies a measuring voltage to a measuring electrode while the dust collection voltage is being applied, thereby measuring the capacitance of a sensor device. The DPF failure detection device also stops applying the dust collecting voltage to the dust collecting electrode in response to the fact that the measured value (CCOL) of this capacitance exceeds a completion criterion (CCOL—TH). Further, the DPF failure detection device applies the measuring voltage to the measuring electrode, thereby measuring the capacitance of the sensor device and obtaining a measured value (CPM), on the basis of which a DPF failure is determined.

    摘要: A sheet supplying unit that supplies sheets includes a sheet accommodation tray that accommodates the sheets in a stacked state, the sheets including a first sheet which is an uppermost sheet in the stack of the sheets and a second sheet which is immediately below the first sheet; a pick-up roller that conveys the sheets in a sheet conveying direction; a detection sensor that detects passage of the sheets and is disposed downstream of the pick-up roller in the sheet conveying direction; and a control unit that controls operations of the pick-up roller in accordance with outputs from the detection sensor. The control unit includes a driving section that drives the pick-up roller to start conveying the second sheet when the detection sensor detects a trailing edge of the first sheet, if the second sheet is to be fed; a suspending section that temporarily stops driving the pick-up roller for a time period α-β when the detection sensor detects a leading edge of the second sheet, α being a predetermined time period, and β being a time period from a timing when the detection sensor detects the trailing edge of the first sheet to a timing when the detection sensor detects the leading edge of the second sheet; and a resuming section that resumes driving the pick-up roller to convey the second sheet after suspending for the time period α-β.
