    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 gear comprised of a tooth surface and a hard carbon film formed on at least a part of the tooth surface. When the gear is used in lubricant including a specific component, a friction of a tooth surface of the gear is largely decreased, and therefore the gear performs an excellent power transmission efficiency. Further, when the gear is employed in a planetary gear mechanism or speed reducing mechanism which has a plurality of meshing portions of gears, the power transmission efficiency of the mechanism is also improved.

    摘要： Provided is a hard carbon film, which is to be used in a sliding member, more specifically, at a sliding site thereof in contact with a counter member. The hard carbon film contains at least one of cobalt and nickel in a total content within the range of more than 1.4 to less than 39 atom % and contains cobalt and nickel aggregates having a diameter of beyond 5 nm within a predetermined ratio or less. In this way, the hard carbon film reduced in friction coefficient than ever, manufactured in a simple process, and effectively working in a wide variety of lubricating oils can be provided.

    摘要： A number-of-compressors controlling system which has a simple configuration and can produce compressed air by immediately following the load used of the compressed air is provided. The number-of-compressors controlling system has a plurality of compressors (2), a receiver tank (3) in which compressed air is supplied from these compressors (2) and is fed to a compressed air utilization device, a pressure sensor (4) provided on the receiver tank (3), and a number-of-compressors controller (5) which changes the number of compressors being operated based on the detected pressure of the pressure sensor (4). A number-of-compressors decreasing pressure as a threshold value whether or not the number of compressors being operated is decreased by the number-of-compressors controller (5) is set to be lower as the number of compressors being operated is larger.
