Abstract:
A slide bearing for internal combustion engines, comprising a slide layer including a lubricant outer layer in which a solid lubricant is contained, and wherein the lubricant outer layer contains an element which is contained in the solid lubricant, at a maximum concentration of not less than 5 mass % in the lubricant outer layer, and at least a solid lubricant gathered particle is formed on a surface of the lubricant outer layer, the solid lubricant gathered particle being a particle of the solid lubricant formed by gathering a plurality of primary particles, the solid lubricant gathered particle having a long side of not less than 20 μm but less than 100 μm in terms of surface visual field of the lubricant outer layer.
Abstract:
The production of solid lubricant agglomerates by combining solid lubricant powder, an inorganic binder, other fillers if optionally desired, and a liquid to form a mixture, and driving off the liquid to form dry agglomerates which are subsequently classified by size or milled and classified by size to yield agglomerates of a desired size range. These agglomerates are then treated to stabilize the binder, thereby strengthening the binder and rendering it nondispersible in the liquid. The treated agglomerates are then blended or clad with a metal, metal alloy or a metallic composition, to produce a composition suitable for thermal spray applications.
Abstract:
The present invention relates to an anti-friction and anti-wear liquid coating composition for use with parts made of materials that have softening points below about 300° F. and articles so coated. The present invention also relates to a method of coating parts made from a low softening point materials with an anti-friction and anti-wear hard coating composition. The coating composition comprises a mixture of (i) solid lubricants comprising boron nitride, graphite and molybdenum disulfide, (ii) a thermoset resin system, (iii) catalyst for curing the resin system and (iv) a solvent system comprising highly volatile solvents. The coating composition is applied to the part and cured to form a coating on the part.
Abstract:
The present invention relates to a method for screening and identifying test compounds that bind to a preselected target ribonucleic acid (nullRNAnull). Direct, non-competitive binding assays are advantageously used to screen libraries of compounds for those that selectively bind to a preselected target RNA. Binding of target RNA molecules to a particular test compound is detected using any physical method that measures the altered physical property of the target RNA bound to a test compound. The structure of the test compound attached to the labeled RNA is also determined. The methods used will depend, in part, on the nature of the library screened. The methods of the present invention provide a simple, sensitive assay for high-throughput screening of libraries of compounds to identify pharmaceutical leads.
Abstract:
The present invention provides an extrudable, crosslinked, greasy heat-radiating material which can find completely new ways of use (in terms of methods of operation and putting it in a service area), because it can be formed into any shape after it is extruded from the container in which it is held (e.g., syringe or tube) to be put or placed in a gap of any shape between a heat-generating body and heat-radiating body, where it keeps shape self-retainability even when kept under a very light load, e.g., kept on a slanted plate, unlike the conventional thermoconductive silicone rubber composition or thermoconductive silicone oil compound, whose applicable areas are limited to formed articles, represented by sheet, and coating. The present invention also provides a container filled with and sealing the extrudable, crosslinked, greasy heat-radiating material, process for producing the container, and method of heat radiation using the container. More specifically, the present invention provides the extrudable, crosslinked, greasy heat-radiating material comprising a crosslinked silicone gel (A) dispersed with a thermoconductive filler (B) and shape self-retainable in spite of being fluid, wherein the thermoconductive filler (B) is incorporated at 5 to 500 parts by weight per 100 parts by weight of the crosslinked silicone gel (A); container filled with and sealing the extrudable, crosslinked, greasy heat-radiating material; process for producing the container; and method of heat radiation using the container put or placed in a gap between a heat-generating body and heat-releasing body.
Abstract:
The present invention provides a new composite material comprising a porous matrix made of metal, metal alloy or semiconducting material and hollow fullerene-like nanoparticles of a metal chalcogenide compound or mixture of such compounds. The composite material is characterized by having a porosity between about 10% and about 40%. The amount of the hallow nanoparticles in the composite material is 1-20 wt. %.
Abstract:

The solid lubricant having from about twenty-five percent to about seventy percent by volume of a polymeric carrier, about five to seventy-five percent by volume of organic and inorganic extreme pressure additives, about zero to twenty percent by volume synthetic extreme pressure anti-wear liquid oil, and about zero to one percent by volume optical brightener.
Abstract:
A self-lubricating coating is provided which includes a mixture of a curable acrylate composition including a dipentaerythritol pentaacylate and a solid lubricant, such as polytetraflourethylenr. The curable acrylate composition may also include triethylene glycol dimethacrylate. An aramid pulp may also be added to the coating mixture. Also disclosed is a method of manufacturing the coating, and a self-lubricating bearing having the coating disposed on its surface.
