Abstract:
A threaded joint for steel pipe formed on a pin and a box having a contact surface including a threaded parts and a non-threaded metal contact part and capable of preventing a galling by repeated fastening and loosening operations without applying compound grease thereto, wherein a solid lubricating film including lubricating powder such as molybdenum disulfide and resin binder is formed on the contact surface of at least one of the pin and the bo by drying the film by primary heating in the temperature range of 70 °C to 150 °C and by a secondary heating in the range of from higher than 150 °C to 380 °C, the solid lubricating film thus obtained has a Rockwell M scale hardness of 70 to 140, an adhesive strength of 500 N/m or higher obtained by the SAICAS (Surface And Interfacial Cutting Analysis System) method, and excellent galling resistance and airtightness even in a high temperature well environment, and, when ultraviolet ray shielding particles such as titanium oxide are contained in the solid lubricating film, the rust-proofness of the threaded joint is increased.
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 mu m to not more than 5 mu m. 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 mu mRz, preferably from 1.0 to 10.0 mu mRz.
Abstract:
Dry film lubricant coatings are provided by using a silicone resin binder, either as an aqueous emulsion or in a solvent-based system, to fix an alkaline earth metal fluoride to a substrate. The compositions used to apply the coatings may also include relatively minor amounts of xylene, ammonium benzoate, a wetting agent, and/or a porosity-inducing agent-although none of those additives remains in the cured coating. Multi-layer dry film lubricant coatings are also disclosed, with the multi-layer coating having a basecoat layer as described above, and a topcoat layer made of a layer-lattice solid such as graphite or molybdenum disulfide, and a silicone resin, aluminum phosphate or an alkali metal silicate binder.
Abstract:
An antifriction coating comprises a lubricant, a corrosion inhibitor, and a solvent, wherein the lubricant comprises a mixture of phenolic resin, epoxy resin, polyvinylbutyral resin and polyolefin wax, and the corrosion inhibitor comprises aluminium particles, zinc particles and a metal phosphate. Substrates are preferably pretreated by a phosphating process prior to coating with the antifriction coating. The antifriction coating is useful for coating substrates such as nuts, bolts and other fasteners, door, bonnet and boot lock parts, hinges, door stoppers, window guides, seat belt components, brake rotors and drums, and other transportation industry related parts. The antifriction coating may be used alone or in combination with other antifriction coating.
