    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.

    摘要: In a lithium ion secondary battery using a negative electrode material powder including a lower silicon oxide powder as a negative electrode material, a charge electric potential at 0.45-1.0 V relative to a Li reference upon initial charging results in a lithium ion secondary battery having a large discharge capacity with excellent cycle characteristics, which can be durable in practical use. On this occasion, the charge electric potential being 0.45-1.0 V relative to the Li reference upon initial charging means that an electric potential plateau caused by the generation of Li-silicate is observed, and the Li-silicate is uniformly generated in the negative electrode material, and this results in excellent cycle characteristics. The negative electrode material powder can have an electrically conductive carbon film on the surface with a ratio of the carbon film to the surface of the powder to be 0.2-10 mass %.
