Abstract: PURPOSE:To prevent an unexpected start-time control mode from being performed by performing control operation from the start-time control mode, when an engine is started, and skipping the start-time control mode to perform control operation from a steady-time control mode in the case of a microcomputer being reset. CONSTITUTION:An integration capacitor 12 is charged by a predetermined time constant through a charging circuit 11 by a power supply circuit 3. The integration capacitor 12 is discharged by a predetermined time constant by a discharging circuit 13. In a mode control means 14, an ignition timing control device 5, after it is started from a start-time control mode, is transferred to a steady-time control mode when terminal voltage is less than a preset value by detecting the terminal voltage of the integration capacitor 12. An operation start-time control mode of the ignition timing control device 5 is controlled so as to be started from the steady-time control mode without performing the start-time control mode when the terminal voltage is at the preset value or higher.

Abstract: PURPOSE:To stably measure flowrate with as low power consumption as possible regardless of the magnitude of fluid noise by correcting a set span so that the ratio of estimated noise level to input converted signal level becomes constant and controlling the amplitude of excitation current. CONSTITUTION:An FFT (noise level meter) 11 reads the noise levels ef1, ef2 of fluid flowing inside a measuring pipe 1 in the frequency range between f1 and f2 putting the excitation fequency fex in between by inputting a signal electromotive force E calculates the noise level efex of fluid at the excitation frequency fex with a linear approximation using an equation and can estimate the level efex. And CPU 12 calculates the ratio of the level efex to the input conversion signal level in a set span predetermined according to the amplitude of the excitation current I, corrects the set span so as to make the ratio a predetermined constant value and controls the amplitude of the excitation current I. Thus, stable flowrate measurement becomes possible with as low power consumption as possible regardless of the magnitude of fluid noise.
