Abstract:
PROBLEM TO BE SOLVED: To provide a sliding bearing having performance equal to or more than that of a rolling bearing, the rolling bearing used for a scroll compressor loaded on an automobile being replaced by the sliding bearing.SOLUTION: In this sliding bearing, a sliding layer is formed by burning on a back metal thereof. The sliding layer is made of 5-60 wt.% graphite, average radius of which is 5-50 μm, degree of graphitization of which is 0.6 or more, in which an average shape coefficient (Y) defined as in the following of particles except fine particles each having a radius of 0.5 times or less of the average radius is 1-4, and which includes particles having a shape coefficient (Y) within a range (Y)=1-1.5 at 70% or more in the ratio of the number, and polyimide resin and/or polyamideimide resin as residues.
Abstract:
A process for drawing wire employing a lubricant comprising perfluorocarbon compounds (PFCs), including aliphatic perfluorocarbon compounds ( alpha -PFCs) having the general formula CnF2n+2, perfluoromorpholines having the general formula CnF2n+1ON, perfluoroamines (PFAs) and highly fluorinated amines (HFAs), and perfluoroethers (PFEs). Such fully and highly fluorinated carbon compounds exhibit a very high degree of thermal and chemical stability due to the strength of the carbon-fluorine bond. Further, because the compounds are fully fluorinated, and therefore do not contain chlorine and bromine, they have zero ozone depletion potential (ODP). Further, because the compounds are photochemically non-reactive in the atmosphere, they are not precursors to photochemical smog and are exempt from the United States Environmental Protection Agency (EPA) volatile organic compound (VOC) definition. Further, because they are volatile, the compounds are easily removed at the end of the process without need for an additional cleaning step. The process provides wire at significantly higher production speeds and longer die life with improved quality and less byproduct debris.
Abstract:
PROBLEM TO BE SOLVED: To provide an image-bearing member protecting agent which can achieve a sufficient protecting effect on the surface of an image-bearing member, prevention of filming on the image-bearing member, and prevention of smearing on a charging member, and to provide a protective layer forming device which can form an excellent protective layer for image-bearing member using the image-bearing member protecting agent. SOLUTION: The image-bearing member protecting agent to be used for an image forming method or an image forming apparatus including an image-bearing member 1 and a step or a device 2 for applying or adhering the image-bearing member protecting agent 21 to the surface of the image-bearing member, includes at least: a hydrophobic organic compound (A); an inorganic lubricant (B); and inorganic fine particles (C), wherein each of the inorganic fine particles (C) has a specific surface area of 2.0 to 6.5 m 2 /g. The protective layer forming device 2 includes at least an image-bearing member protecting agent 21 and a protecting agent supply member 22, and supplies the image-bearing member protecting agent 21 to the surface of the image-bearing member 1 via the protecting agent supply member 22.

Abstract:
A lubrication mechanism of a strain wave gearing is disposed in an interior space of an externally toothed gear and comprises a powder-accommodating bag that stores solid lubricant powder. A diaphragm of the externally toothed gear is repeatedly deflected during the driving of the strain wave gearing. Vibration or deflection is repeatedly imparted to the powder-accommodating bag and the solid lubricant powder is discharged from a powder discharge hole formed in the powder-accommodating bag into the interior space. A site to be lubricated is lubricated with the solid lubricant powder discharged into the interior space. Harmful effects due to a large amount of the solid lubricant powder being supplied to the site to be lubricated at one time can be resolved, and a necessary amount of the solid lubricant powder can be continuously supplied to the site to be lubricated.
Abstract:
A rim-rotor assembly has an annular structure including a composite rim and a hub. Blades project from the hub, tips of the blades contacting the annular structure, the blades configured to be loaded in compression against the annular structure. A thermal barrier is in the annular structure, the thermal barrier defining at least part of a radially inward surface of the annular structure. The tips of the blades contact the thermal barrier, the thermal barrier being a thermal barrier coating.
