Abstract: An electronic camera apparatus includes an image pick-up unit for obtaining image data of a moving image every certain frame period, a recording unit for performing a data-writing process to successively write the image data onto a detachable recording medium, and a rate obtaining unit for obtaining information concerning a data-writing rate at which the recording unit writes the image data onto the recording medium. In addition, the electronic camera apparatus includes an adjusting unit for adjusting, based on the data-writing rate obtained by the rate obtaining unit, values of image recording parameters for determining an image data volume to be written onto the recording medium in a fixed period of time to restrict the image data volume to a level less than a data volume which can be written on the recording medium within the fixed period of time.

Abstract: A diagnostic system in which the accuracy of the diagnosis of the deterioration state of a catalyst in a catalytic converter for cleaning the exhaust gas of an internal combustion engine is enhanced without incurring a rise in cost. The temperature of the catalyst is estimated using the operating-state signal (for example, the flow rate of intake air or the width of a fuel injection pulse) of the engine by a diagnostic device. The conversion efficiency of the catalyst calculated from the outputs of oxygen sensors is corrected using the estimated temperature by the diagnostic device. The deterioration state of the catalyst is diagnosed on the basis of the corrected temperature by the diagnostic device.

Abstract: A stream recording of a moving image is executed every frame period. In case a frame data of the previous frame is still being written (YES at step SA4) at the time when the latest frame data is to be written, the latest frame data is set aside and a dummy counter is incremented by “1” at step SA9. Thereafter, when the frame data of the previous frame has been written (NO at step SA4), a dummy frame corresponding to the dummy counter is written on a recording medium at step SA11. A normal moving-image recording operation is continued by temporarily reducing a superficial frame rate in a reproduction, preventing temporal failure in an image recording process, whereby a user is allowed to set the upper limit of the recorded image quality to the high side.

Abstract: 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.

The diagnosis apparatus is capable of precisely diagnosing the evaporation system even in the case where dirt or stain or the like adheres to the gauge valve and an air cleaner. A gauge pipe is branched between a fuel tank and a purge valve and opened to an intake pipe or atmosphere, and a gauge valve is arranged in the gauge pipe. A state detector is provided for detecting the state of a gauge system comprising the gauge valve and the gauge pipe, and a correcting feature corrects the results of diagnosis by abnormality determination apparatus on the basis of the results of detection by the state detector.

Abstract: A diagnostic and control system first checks the current operation status of the vehicle engine, when a malfunction or abnormal condition is detected by diagnostic sensors. A selection of optimum corrective measures is then made and carried out taking into account the safety of the vehicle, based on current operational status of the engine. For this purpose, a set of prioritized corrective measures is determined beforehand for each of the individual monitored items, according to detected changes in the engine operating status. The individual control measures are selected considering the safety of the vehicle, possible measures to correct the malfunction, assuring vehicle operability, and maintaining appropriate engine operating parameters such as exhaust gas mixture, fuel consumption and the like.

Abstract: A conversion efficiency of a catalyst is determined by a cross correlation function of a cross-correlation between an output of an oxygen sensor at the upstream of the catalyst and an output of an oxygen sensor at the downstream of the catalyst, to thereby monitor deterioration index of the catalyst. Then, an air and fuel ratio is obtained from at least one of the outputs of the two oxygen sensors, to thereby adjust a fuel supply quantity, so that the fuel supply quantity can be controlled even during a period when the catalyst is being analyzed, without deviating the air and fuel ratio from a target air and fuel ratio.

Abstract: This invention performs a diagnosis on the evaporative system in a short period of time by pulling down the evaporative system with a negative pressure of the intake manifold of the engine and by checking a change in the internal pressure of the evaporative system being pulled down. To realize this diagnosis, when introducing a negative pressure from the intake manifold, the pulldown rate is changed based on the internal pressure of the evaporative system. Because the pulldown rate is corrected and controlled during the diagnostic process, a preliminary process for the diagnosis can be eliminated, shortening the time required for the diagnosis. Further, this method allows the evaporative system to be diagnosed without being influenced by external factors such as atmospheric pressure, the internal volume of the evaporative system, the amount of evaporative gas generated, or presence or absence of leakage.
