摘要:
A piston ring mounted in the ring groove of an aluminum alloy piston does not cause aluminum adhesion during the long-term use. The piston ring includes a resin film deposited on at least one of an upper face and a lower face. The resin film contains from 0.5 to 20% by volume of carbon black particles and from 3 to 30% by volume of solid lubricant particles with respect to the total volume of the resin film. The carbon black particles preferably contain one or both of graphitized carbon black particles and composite graphite black particles.
摘要:
Provided is a piston ring capable of maintaining an excellent effect of preventing aluminum cohesion in a high output engine over a long period of time. At least one of the upper, lower, and side faces of the piston ring is coated with a silica-based coating in which hard nanoparticles are dispersed. The coating has a Martens hardness of 1,000 to 8,000 N/mm2. As the hard nanoparticles, carbon nanoparticles, nanodiamond particles, carbon nanotubes, or carbon nanofibers are used. To the coating, resin particles of a fluorine-based resin or a polyether-based resin may be added.

摘要:
The present invention provides a gel beverage composition for comprehensive nutritional supplementation, having balanced nutrients, refreshing taste, a low pH, a soft gel form suitable for drinking/eating and the ability to retain its gel form for a long period of time. The composition is a gel which has a pH ranging from 3-4 and contains 5-20% by weight of saccharide, 0.1-5% by weight of fat, 2.5-6% by weight of protein material which does not coagulate at pH 3-4, 0.2-3% by weight of citric acid, 0.2-1.5% by weight of at least one acid component selected from the group consisting of ascorbic acid, tartaric acid, succinic acid, malic acid, gluconic acid, phosphoric acid, phytic acid, lactic acid and trisodium citrate, 0.01-0.5% by weight of an emulsifying agent, 0.1-1% by weight of agar and 65-90% by weight of water.
摘要:
The present invention provides a food composition for inhibiting the formation of an intestinal putrefactive product, containing lactosucrose as an effective component. This food composition is low in calorific value because the lactosucrose is indigestible, and can decrease the amount of an putrefactive product to be generated in intestines. Accordingly, this food composition effectively prevents the outbreak of a variety of cancers for which the putrefactive product might serve as a promoter.
