    摘要： An automatic focusing apparatus for use with a camera of the type having two interchangeable lenses with different focal lengths, incudes a ranging device for finding in which distance range is located an object to be photographed, i.e., close range or long range. The ranging device is capable of shifting the position of the boundary between short range and long range when interchanging lenses in order to widen the limits of the range in which either of the lenses can be focused better.

    摘要： A diagnostic equipment for an exhaust gas cleaning apparatus installed for an engine, comprising a misfire detector which detects the misfire of the engine, and a secondary-air-system failure detector which detects the failure of a secondary air system. An index corrector corrects a deterioration index calculated by a deterioration-index calculator, in accordance with the detected result of the detector. A deterioration decision unit decides if the diagnostic equipment has failed, by the use of the corrected deterioration index. In a case where the extent of the misfire or the like is severe, a decision interrupter interrupts the decision of the deterioration decision unit. Thus, even when the misfire of the engine or the failure of the secondary air system has occurred, the detection of the deterioration of a catalyst does not err. It is therefore avoided to erroneously replace the catalyst which has not deteriorated yet, or to run the engine in spite of the deterioration of the catalyst.

    摘要： A diagnosing system for an engine diagnoses malfunctions that occur in a direct-injection engine in which fuel is injected into combustion chambers or a lean-burn engine. The present invention provides a diagnosing system for an engine capable of diagnosing malfunctions in an intake air flow intensifying component and a fuel supply component and of specifying a malfunctioning part without being affected by the difference between different engines, the difference in quality between parts and aging. The diagnosing system for an engine comprises: a selecting component for selecting either a first air-fuel mixture control component or a second air-fuel mixture control component according to operating condition of an engine; a combustion condition detecting component for detecting combustion condition of the engine; and decision component for deciding a malfunction on the basis of a first combustion condition detected by the combustion condition detecting component in a state where the first air-fuel mixture control component is selected by the selecting component, and a second combustion condition detected by the combustion condition detecting component in a state where the second air-fuel mixture control component is selected by the selecting component.
