Abstract: A lubricating grease composition comprising (A) a base oil, (B) 5 to 10 wt. % of a urea compound, (C) 0.5 to 20 wt. % of at least one phosphorous compound selected from the group consisting of a phosphoric acid salt etc., and (D) 0.5 to 40 wt. % of a fatty acid metal salt. Aforementioned lubricating grease composition allows it to reduce the friction coefficient and prolong the endurance life significantly when it is applied onto surfaces of the sliding pair consisting of metal and plastic (especially glass-fiber-reinforced plastic) parts.

Abstract: A heat dissipation assembly in which a heat generator and a heat dissipator are integrated via an electrically insulating and thermally conductive sheet, at least one surface of which a thermally conductive grease is applied to, in which the thermally conductive grease is incompatible with the electrically insulating and thermally conductive sheet. Heat from the heat generator such as a semiconductor device or the like can be effectively dissipated while an electrically insulating condition is maintained over a long period of time.
