Abstract: An ion current detection device of an internal combustion engine includes a detection voltage generation device which applies a voltage to an ignition plug to generate an ion current in a cylinder of the engine. A current to voltage conversion circuit detects and converts the generated ion current to a voltage signal. A bandpass filter extracts an ac component within a specified frequency range from the voltage signal produced by the current to voltage conversion circuit. An ion current threshold detection portion produces an ion current detection signal when the detected ion current exceeds a predetermined threshold current. A filter characteristic control circuit controls the characteristic of the bandpass filter to suppress the sensitivity of the filter for a predetermined period of time right after the ion current detection signal is detected and, after the predetermined period of time, increase the sensitivity of the filter for detection of the ac signal with the specific frequency.

Abstract: A counting circuit including destructive memory elements detection circuits for detecting whether the memory elements are broken, and control circuits for controlling the supply of a break current to the memory elements in a plurality of stages. A current feed circuit supplies the break current for breaking the memory elements in the counting circuit every time a to-be-counted write pulse is input. The control circuit in each stage of the counting circuit supplies the break current from the current feed circuit to the memory element of the stage based on a detection result of the detection circuit only when the memory element of the stage is unbroken while the memory element of a stage preceding the memory element is broken. The control circuit of the first stage supplies the break current to the memory element of the first stage when the memory element of the first stage is unbroken.

Abstract: A waveform shaping circuit shapes a waveform by comparing an output signal generated by an electromagnetic coil in response to a change in an incident magnetic flux to a reference voltage in a comparator. The circuit prevents waveform shaping error due to rapid fluctuations in the output signal. The waveform shaping circuit includes a high-pass filter that removes low-frequency components having frequencies not higher than a cut-off frequency from the output signal of the electromagnetic coil and that has at least two different attenuation characteristics with respective cut-off frequencies, a voltage limiting circuit for switching between the attenuation characteristics of the filter in response to the amplitude of the output signal of the electromagnetic coil by limiting the amplitude of the output signal to a maximum voltage, and a comparator for comparing the filtered output signal with a reference voltage and generating a shaped output signal in response.
