    • A clock forming unit, a selection processing unit, and a dithering control unit are provided. In the clock forming unit, m-phase clock signals whose phases are mutually deviated by a predetermined amount at a desired frequency are formed. The clock signals formed in the clock forming unit are supplied to the selection processing unit. A control signal is supplied from the dithering control unit to the selection processing unit. In the selection processing unit, by sequentially selecting one of the m-phase clock signals in response to the control signal from the dithering control unit, the phase is fluctuated forward and backward with a predetermined relation within a range of a precision that is permitted by a communication system serving as a supplying destination. A second clock signal in which a peak on a spectrum is spread is obtained from the selection processing unit.

    • There is disclosed a leakage diagnosis of an evaporative system in an internal combustion engine, and more particularly there is disclosed an evaporative system in which a more accurate leakage diagnosis can be effected using a change in the pressure in the evaporative system, and such a diagnosis method is also disclosed. The evaporative system includes a gauge line having a gauge valve, which gauge line branches off from an evaporative gas line or an evaporative gas purge line, and communicates with a point upstream of an engine throttle valve or with the ambient atmosphere, a pressure sensor for detecting the pressure in the evaporative system, and a purge valve. A leakage diagnosis of this system is effected based on detected values of the pressure sensor obtained by opening and closing the purge valve and the gauge valve. Therefore, accurate results of the diagnosis can be obtained.
