摘要： A sliding structure for an automotive engine includes a sliding member with a sliding portion and a lubricant applied to the sliding portion so that the sliding portion can make sliding contact with a counterpart member via the lubricant. The sliding member is either of a piston ring, a piston pin, a cam lobe, a cam journal, a plain bearing, a rotary vane and a timing chain. The sliding portion has a base made of a steel or aluminum material and a hard carbon film formed on the base to coat the sliding portion. The hard carbon film has a thickness of 0.3 to 2.0 μm, a Knoop hardness of 1500 to 4500 kg/mm2, a surface roughness Ry (μm) satisfying the following equation: Ry

摘要： A piston for an internal combustion engine of an automotive vehicle. The piston has a piston ring and a piston skirt section each of which has a sliding section in slidable contact with a cylinder bore section of a cylinder block in presence of a lubricating oil. The cylinder bore section is formed of eutectic or hyper-eutectic aluminum alloy. Additionally, a hard carbon thin film is coated on the sliding section of the piston and contains hydrogen atom in an amount of not more than 1 atomic %. Here, the lubricating oil contains at least one selected from the group consisting of ashless fatty acid ester friction modifier, ashless aliphatic amine friction modifier, polybutenyl succinimide, derivative of polybutenyl succinimide, zinc dithiophosphate, and derivative of zinc dithiophosphate.

摘要： A moving picture encoder which is able to improve the encoding efficiency wherein a controller controls an inter/intra mode switch for generating intra and inter signals Y2 and Y4, these signals being stored in a memory. A combining unit generates a combination pattern from the intra and inter signals Y2 and Y4 stored in the memory. An information amount estimator estimates the information amounts concerning the signals Y2 and Y4 and combination pattern. A minimum information amount determining unit determines the minimum one of the estimated information amounts. The controller causes a selector to select the signal or combination pattern that corresponds to the minimum information amount for quantizing and transmitting the result to a succeeding stage.
