摘要： At the start-up of an engine, the ignition timing and the air-fuel ratio are controlled to prevent overload onto the volume of ISC air and decreased torque and torque difference.The fuel condition based on the amount of ignition timing correction to inhibit rotational fluctuation during idling is determined and the fuel quantity based on the result is corrected.Right after an engine has started and until a pilot burner is created in the heat spot of the catalyst, the ignition retard control is mainly executed, and at the time when it is determined that a pilot burner has been created in the catalyst's heat spot, the lean air-fuel ratio control is to be executed instead of the ignition retard control. Furthermore, when the ignition retard control changes to the lean air-fuel ratio control, the state transition control is executed along the equivalent ISC air volume line so as not to cause torque fluctuation.

摘要： 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.

摘要： A font converting device converts (dot density conversion) a down-line load font received through an interface device into a font represented by a dot matrix of the same size as that of a resident font stored in first memory and stores the converted down-line load font in a second memory. A control circuit selectively reads the fonts of the first memory (resident font) or the fonts of the second memory (converted down-line load font) in conformity to a font code included in print data, edits dot image data, and then provides the same to a printing unit to be controlled, namely, a printer in a narrow sense. Only the rarely used down-line load font is subjected to dot density conversion so that the print dot density of the converted down-line load font coincides with that of the print dot density of the printer to be controlled, while a frequently used font of a print dot density coinciding with that of the printer is stored as resident font. Thus, a plurality of printers differing from each other in print dot density can be connected to the host unit of a system in the same interface conditions without entailing the variation of character pattern and the size of print area.

摘要： A lens-fitted photographic film package has at least an unexposed rolled film, a taking lens, a film transportiong mechanism, an exposure mechanism and an electronic flash as a whole contained in a light-tight case. The light-tight case comprises a main case section formed with a chamber containing therein light-tightly the unexposed rolled film and a front cover section attached to the main case section, the front cover section being formed with at least one opening for partially receiving therein a member of at least one of the mechanisms mounted on the main case section projecting beyond a plane defined by surfaces of the main case section in contact with an inner surface of the front cover section when the front cover section is securely attached to the main case section. The electronic flash unit is short-circuited to maintain the condenser of the flash unit discharged until the rolled film has been loaded in the light-tight case, so as to prevent accidental flashing that would expose the film. The lens-fitted photographic film package is enclosed in an external container having a weakened openable portion capable of being broken away from the external container to expose the contained rolled film for removal after exposure.
