摘要:
Under wet sliding conditions using drivetrain system lubricating oils, a high frictional sliding member exhibiting a high friction coefficient, a favorable μ−v characteristic stably, excellent wear resistance, and low mating-member aggressiveness is provided. The present invention is a wet sliding member comprising: a substrate composed of metal, ceramics, or resin; and an amorphous hard carbon film formed integrally on a surface of the substrate, having a surface, at least a part of which is turned into a sliding surface for sliding under wet conditions, and containing at least either one of Si and N in an amount of from 1 to 50 atomic %.
摘要:
A method of lithographically patterning a substrate that has photoresist having removal areas and non-removal areas includes first exposing at least the non-removal areas to radiation effective to increase outer surface roughness of the photoresist in the non-removal areas at least post-develop but ineffective to change photoresist solubility in a developer for the photoresist to be cleared from the non-removal areas upon develop with the developer. Second exposing of radiation to the removal areas is conducted to be effective to change photoresist solubility in the developer for the photoresist to be cleared from the removal areas upon develop with the developer. The photoresist is developed with the developer effective to clear photoresist from the removal areas and to leave photoresist in the non-removal areas that has outer surface roughness in the non-removal areas which is greater than that before the first exposing. Other implementations and embodiments are contemplated.

An amorphous carbon film includes carbon as a major component, and silicon in an amount of from 0.1 atomic % or more to 10 atomic % or less when the entire amorphous carbon film is taken as 100 atomic %. The carbon is composed of carbon having an sp2 hybrid orbital in an amount of from 60 atomic % or more to 90 atomic % or less when the entire carbon amount is taken as 100 atomic %. Also disclosed is a process for producing the amorphous carbon film.
摘要:
A low-friction sliding member is used under a wet condition employing a lubricant, and includes a substrate having a surface, and an amorphous hard carbon film formed on the surface of the substrate for contacting slidably with a mating member. The amorphous hard carbon film includes silicon in an amount of from 1 atomic % or more to 20 atomic % or less, hydrogen in an amount of from 20 atomic % or more to 50 atomic % or less, and the balance of carbon and inevitable impurities, when the entirety is taken as 100 atomic %, and exhibits a surface roughness Rzjis of 0.8 μm or less. The low-friction sliding member exhibits reduced friction coefficients between itself and mating members, without relying on the adsorption and reaction of additives, included in lubricants, to the amorphous hard carbon films.

In a die assembly, plural pairs of extrusion ports are set up on concentric circles different in diameter. The die assembly is also provided with a core material feeding layer which spreads in such a planar state as to be connected to all core material extruding passageways and a sheath material feeding layer which spreads in such a planar state as to be connected to all sheath material extruding passageways and the core material and the sheath material are fed through the passageways. This constitution makes it possible to set up extrusion ports in arbitrary positions corresponding to the core material feeding layer and the sheath material feeding layer which each spread in a planar state, which enables simultaneous production of more multilayer extrusions while inhibiting the enlargement of the assembly.

A drive force transmission device has an outer clutch plate and an inner clutch plate, which are rotatable relative to each other about a common rotational axis. The inner and outer clutch plates become frictionally engaged with each other with lubricant oil provided in between. The outer and inner clutch plates each have a sliding surface. The sliding surfaces face each other. A diamond-like carbon film is formed on the sliding surface of the outer clutch plate. Fine grooves are formed in the sliding surface of the inner clutch plate. The proportion of the sliding area to the sliding surface of the inner clutch plate at the initial stage of use is 55 to 90%.
