摘要： An MPEG image decoding apparatus and method is disclosed, by which normal images can be supplied even if a bit stream is a nonstandardized bit stream having an error. The apparatus comprises a buffer for temporarily storing data of an input bit stream and outputting the stored data in input order; a register for storing the data output from the buffer in its empty area; a first data-search section for searching the data stored in the register so as to detect a specific code by executing a byte-unit collating operation; a second data-search section for searching the data so as to detect a specific code by executing a bit-unit collating operation; a control section for choosing one of outputs from the first and second data-search sections; a shifter for extracting a retrieved data from among the data stored in the register based on the chosen output, and shifting the remaining non-retrieved data towards the head of the register and making an empty area in the register; and a decoder for decoding the retrieved data.

摘要： An air/fuel ratio control system is provided for use with an internal combustion engine. The system includes a first air/fuel ratio detector arranged on an upstream side of a catalytic converter so as to detect the air/fuel ratio of the engine from components of exhaust gas, a second air/fuel ratio detector arranged in the exhaust system and having a detection response speed slower than the first air/fuel ratio detector, a device for controlling the air/fuel ratio of the engine on the basis of results of a comparison between a detection value from the first air/fuel ratio detector and a predetermined first reference value, a device for effecting a correction to the control of the air/fuel ratio by the air/fuel ratio control device on the basis of results of a comparison between a detection value from the second air/fuel ratio detector and a predetermined second reference value, and a device for shifting the second reference value to a lean air/fuel ratio side in a specific operation state of the engine.
