摘要： Oil grooves (40) formed in at least one of surfaces of a ring-shaped member (30) each have a longitudinal direction that forms an angle falling within a range of from 40 degrees to 75 degrees with respect to a radial direction of the ring-shaped member, and are arranged at equal intervals in a circumferential direction of the ring-shaped member (30). The oil grooves (40) include communicating oil grooves (40A) and non-communicating oil grooves (40B) formed to extend to the vicinity of an outer peripheral end (34), and are arranged with periodic regularity in the circumferential direction of the ring-shaped member (30). In addition, a communicating oil groove area ratio expressed by Expression: “S1/(S1+S2)” falls within a range of from 0.15 to 0.85, where S1 represents a sum of plane areas of the communicating oil grooves (40A), S2 represents a sum of the non-communicating oil grooves (40B).

摘要： An aspect of the present invention provides a binder which makes it possible to obtain an electrode excellent in heat resistance. The binder contains: a re-emulsifiable resin powder coated with inorganic particles; and a metal-crosslinking thickening agent forming a hydrophobic gel by being crosslinked, in an aqueous system, via metal ions derived from an electrode active material.

摘要： Provided is a cast iron material from which excellent friction characteristics can be obtained. Provided is the cast iron material containing C and Fe as a composition, and further containing Cr as the composition in 1.0 to 3.5% in terms of mass %. The cast iron material is used in a sliding component sliding under an environment of lubricating oil to which an additive containing Mo as a constituent element, such as MoDTC, is added. Cr contained in the cast iron material promotes a decomposition reaction of the additive containing Mo added to the lubricating oil to form a film of molybdenum disulfide, the film having low friction. Thus, the fiction can be reduced.

摘要： This core-shell composite (10) is provided with a core (11) formed from a porous carbon body having a large number of pores from the interior through to the surface, and a shell layer (12) formed from conductive polymer nanorods (12a) that extend outward from the cavities of the pores (11a) on the surface of the core. The present invention provides the core-shell composite (10), to which electrolyte ions can be efficiently adsorbed or doped, a method for producing the core-shell composite, as well as an electrode material, a catalyst, an electrode, a secondary battery and an electric double-layer capacitor that use the core-shell composite.
