Abstract:
A method for treatment of bacterial infections with rifalazil administered once-weekly, or twice-weekly. A method for treatment of tuberculosis caused by Mycobacterium tuberculosis, infections caused by Mycobacterium avium complex, infections caused by Chlamydia pneumoniae and infections caused by Helicobacter pylori by administering to a patient suffering from the bacterial infection 1-100 mg of rifalazil once or twice a week. In this dose regimen, the treatment is fast, efficacious and eliminates undesirable secondary symptoms observed with daily doses of 1-50 mg of rifalazil.
Abstract:
A stainless steel wire is plated with nickel (Ni) to a thickness of from not less than 1 µm to not more than 5 µm. An inorganic salt coat film mainly composed of at least one of potassium sulfate and borax (borate) and free from fluorine (F) or chlorine (Cl) is then deposited on the nickel (Ni) plate 2 as the substrate. The steel wire is then drawn to a reduction of area of not less than 60% to adjust the surface roughness thereof to a range of from 0.80 to 12.5 µmRz, preferably from 1.0 to 10.0 µmRz.
Abstract:
A heat-reducing silicone grease composition comprising a mixture of (A) 50-95 weight % of aluminum nitride powder having an average particle size of 0.5-10 µm and containing no particles 100 µm or greater in size, (B) 5-50 weight % of liquid silicone having a viscosity of 50-500,000 cs at 25°C and (C) 0-30 weight % of at least one powder selected from the group consisting of zinc oxide, alumina, boron nitride and silicon carbide powders; and a semiconductor device to which the foregoing silicone grease composition is applied.
Abstract:
Provided are a thermally conductive silicone composition, a thermally conductive material and a thermally conductive silicone grease, wherein a liquid silicone, an aluminum nitride powder and a zinc oxide powder are comprised, and wherein the total amount of those powders are from 500 to 1,000 parts by weight per 100 parts by weight of the liquid silicone and the ratio of the zinc oxide powder to the sum total of the aluminum nitride powder and the zinc oxide powder is from 0.05 to 0.5 by weight. The products of the present invention are suitable for removal or reduction of heat generated from electric and electronic appliances when in use.
Abstract:
The present invention provides lubricant compositions for the powder metallurgical field. The lubricant compositions contain a solid phase lubricant such as graphite, molybdenum disulfide, and polytetrafluoroethylene in combination with a liquid phase lubricant that is a binder for the solid phase lubricant. The binder can be chosen from various classes of compounds including polyethylene glycols, polyethylene glycol esters, partial esters of C3-6 polyhydric alcohols, polyvinyl esters, and polyvinyl pyrrolidones. The binder is solubilized in an organic solvent.
Abstract:
A lubricant for use in hot rolling of high chromium stainless steel, the lubricant being continuously supplied to surfaces of hot rolling rolls in contact with the steel being rolled at least during hot rolling of the stainless steel, which lubricant comprises a viscous aqueous solution of water soluble high molecular weight thickener and from 10 to 40% by weight of iron hydroxide powder dispersed in the aqueous solution, said iron hydroxide powder having a median particle size of from not less than 0.1 µm to less than 1 µm and said lubricant having an apparent viscosity within the range of from 1,000 to 50,000 cP.
Abstract:
A recirculating powder lubricant delivery system having improved oxidative stability and a lubricant therefor where the lubricant is a solid lubricant selected from a group of molybdenum disulfide, graphite and graphite fluoride, and wherein the solid lubricant is microencapsulated from an aqueous suspension of an alkali metal silicate containing a water soluble phosphate.
Abstract:
A surface-coated rubber or plastic sliding member having a coating with excellent durability and high slipperiness,wherein the coating comprises a solid lubricant such as molybdenum disulfide, a resin matrix and a reinforcement, said resin matrix comprising a fluoroolefin vinyl ether polymer resin and/or a fluoroolefin vinyl ether/vinyl ester copolymer resin.
