摘要： A low-level light detector includes an avalanche photodiode (APD) to which is applied a bias voltage adjusted to produce a multiplication factor of not more than 30, and a capacitor for accumulating carriers produced by light in the APD and multiplied using the APD characteristics, the capacitor being connected to the avalanche photodiode. The detector detects the intensity of light impinging on the avalanche photodiode by periodically reading the capacitor voltage and obtaining time-based differences in the voltage, or by resetting the capacitor voltage to a predetermined voltage each time the capacitor voltage is read.

摘要： An ignition timing control apparatus for an internal combustion engine having a plurality of cylinders, wherein operation of the engine is switchable between a partial-cylinder operation, which operates some of the cylinders, and an all-cylinder operation, which operates all of the cylinders. Basic ignition timing is calculated according to an operating condition of the engine. Knocking is determined based on an output of the knock sensor. A correction amount of the ignition timing is calculated according to a result of the knocking determination to suppress knocking, and the basic ignition timing is corrected with the calculated correction amount. Learning values of the correction amount are calculated corresponding, respectively, to partial-cylinder operation and all-cylinder operation, and one of the calculated learning values is used according to the operating condition of the engine.
