摘要： An optical tomographic imaging method is provided in which light from a light source is split into a measuring beam and a reference beam, the measuring beam being moved by a scanning optical system and guided to an object to be examined, the reference beam being guided to a reference mirror, and in which a tomogram of the object is generated from a return beam of the measuring beam reflected or scattered by the object and the reference beam reflected by the reference mirror. The method includes acquiring longitudinal sectional information on the object, calculating depth-position information on the object from the longitudinal sectional information, and acquiring a three-dimensional surface image of the object by controlling a reference-path length defined by the reference mirror and a scanning operation of the scanning optical system in accordance with the depth-position information on the object.

摘要： An air-fuel ratio control apparatus estimates, on the basis of an exhaust air-fuel ratio of exhaust gas flowing into an exhaust purifying catalyst unit disposed in an exhaust passage of an engine, an emission of at least one specific component contained in exhaust gas flowing out of the exhaust purifying catalyst unit. The air-fuel ratio control apparatus performs the estimation by use of a model, and controls the air-fuel ratio in such a manner that the estimation value reaches a target state. The model is previously determined in consideration of the mass balance of the specific component.

摘要： A controller executes temperature rise control on a catalyst device by retarding ignition timing that is set based on engine operating conditions. The controller reaches a diagnosis that the temperature rise control is normal if an advance angle side accumulated time for which the ignition timing is set exceeding a threshold value to an advance angle side during execution of the temperature rise control is less than an accumulated time determination value. When the advance angle side accumulated time is greater than or equal to the accumulated time determination value, the controller reaches a diagnosis that the temperature rise control has an anomaly.
