摘要： The invention provides a liquid crystal panel substrate having transistors and reflectors connected to the transistors on a substrate to allow bright reflection display of high quality at wide viewing angles by providing the most suitable reflection characteristics to the reflectors. Under the reflectors, first conductive layers are overlaid in regions corresponding to the reflectors and formed in a concave-convex condition by forming a large number of openings. Also, in a plan view, a light-shielding film covering gaps between the reflectors is formed of the second conductive layer, and may have no openings.

摘要： An air-fuel ratio control system includes an air-fuel ratio sensor (23, 24) disposed upstream or downstream of an exhaust purification catalyst, and performs feedback control of the fuel supply amount such that an output value of the air-fuel ratio sensor is controlled to the target air-fuel ratio. The feedback control is performed by calculating a correction amount by summing up the value of a proportional and the value of an integral calculated based on the deviation between the output value of the air-fuel ratio sensor and the target air-fuel ratio, and correcting the fuel supply amount based on the obtained correction amount. At cold startup of the internal combustion engine, the value of the integral is set to be a smaller value from the startup of the internal combustion engine until a predetermined period elapses.

摘要： A signal applied to a data line is binarized to provide a high-quality gray scale presentation. To provide eight gray scales, for example, one field is divided into seven subfields in accordance with gray scale characteristics of an electro-optical device. Pixels are turned on or off by writing a high-level or a low-level signal thereon in a first subfield. In subsequent subfields, high-level or low-level signals are written depending on the gray scale level of each pixel to control the ratio of the on period of the pixels to the off period of the pixels on one field.
