摘要:
An air-fuel ratio control system for an internal combustion engine has an air-fuel ratio sensor arranged in the exhaust system of the engine, for detecting the air-fuel ratio of exhaust gases emitted from the engine, and various engine operating parameter sensors for detecting operating conditions of the engine. An ECU controls the air-fuel ratio of an air-fuel mixture to be supplied to the engine to a desired air-fuel ratio in a feedback manner responsive to an output from the air-fuel ratio sensor. A first learned value for correcting the desired air-fuel ratio is calculated based on the feedback control when the engine is detected to be in a first predetermined operating condition, and a second learned value for correcting the desired air-fuel ratio when the engine is detected to be in a second predetermined engine operating condition. The air-fuel ratio of the air-fuel mixture is controlled to a value leaner than a stoichiometric value, by using the first learned value. The first learned value is learned again when the difference between the first and the second learned values is larger than a predetermined re-learning-determining threshold value.

There is provided a control system for an internal combustion engine. An amount of variation in the rotational speed of the engine is detected. A rotational speed variation reference value is calculated based on an averaged value of the detected amount of variation in the rotational speed of the engine. The detected amount of variation in the rotational speed of the engine is compared with the rotational speed variation reference value. The amount of fuel to be supplied to the engine is corrected based on results of the comparison.

Methods of polymer deposition for forming reduced critical dimensions are described. In one embodiment, a substrate is provided into a chamber, the substrate having a patterned layer disposed on an underlying layer formed thereon. The patterned layer includes a plurality of openings, each opening having a sidewall, a bottom, and a critical dimension. A gas mixture is provided into the chamber, the gas mixture having an etching gas and a polymer control gas. The polymer control gas includes a polymerizing fluorocarbon CxFy gas and a C—H bond containing gas. A plasma is formed with the gas mixture and a conformal polymer layer is deposited in the presence of the plasma on the patterned layer to form a reduced critical dimension in each opening. The reduced critical dimension is smaller than the corresponding critical dimension of the opening.

The image forming apparatus includes a chassis, a paper guide, a paper feed roller, and a paper supply portion from which the paper feed roller is configured to supply paper. The paper guide is supported within the chassis and has a base portion and a first separation portion that projects from the base portion. The paper feed roller is rotatably supported by the chassis. The paper supply portion has a guide projection on its first lateral side portion. The widthwise center of the paper feed roller is offset toward the first lateral side relative to the widthwise center of the first separation portion.
