    Abstract: PROBLEM TO BE SOLVED: To provide a roller and cage assembly, and a bearing employing the roller and cage assembly exhibiting such properties that a film formed by surface treatment causes no increase in stress and is not peeled off from the cage even if the film is thick, surface treatment is not affected by an additive included in oil for use, the wear of the cage can be prevented when the cage is used in an engine with large displacement or the like, and adhesiveness between the surface treatment layer and a substrate is improved.SOLUTION: The cage 2 is plated to form a primary plated layer 4 on the surface, and further plated to form a plated multilayer 5 comprising a plurality of plated layers on the surface of the primary plated layer 4. The plated multilayer 5 has a Ni PTFE plated layer formed on the surface of the primary plated layer 4, another plated layer which is formed on the surface of the Ni PTFE plated layer and has the same plating as that of the primary plated layer 4, and a Ni PTFE plated layer formed on the surface of the another plated layer.

    Abstract translation: 要解决的问题：为了提供一种滚子和保持架组件，以及一种使用具有这样的特性的滚子和保持架组件的轴承，即通过表面处理形成的薄膜不会增加应力，并且不会从保持架中剥离，即使 薄膜厚，表面处理不受包含在使用的油中的添加剂的影响，当保持架用于大排量等的发动机时，可以防止保持架的磨损，并且表面处理层和 改善了基材。 解决方案：保持架2被镀覆以在表面上形成初级镀层4，并且进一步镀覆以形成在主镀层4的表面上包括多个镀层的镀层多层5。镀层多层5 在主镀层4的表面上形成有Ni PTFE镀层，形成在Ni PTFE镀层的表面上并具有与一次镀层4相同的电镀的另一镀层，Ni 镀层形成在另一镀层的表面上。 版权所有（C）2012，JPO＆INPIT

    Abstract: Provided is a heat conductive silicone grease composition including (A) 100 parts by mass of an organopolysiloxane containing 2 or more alkenyl groups bonded to silicon atoms within each molecule, (B) an organohydrogenpolysiloxane containing 2 or more hydrogen atoms bonded to silicon atoms within each molecule, in sufficient quantity to provide from 0.1 to 5.0 hydrogen atoms bonded to silicon atoms within the component (B) for each alkenyl group within the component (A), (C) 100 to 2,200 parts by mass of a heat conductive filler, (D) an effective quantity of a platinum-based catalyst, and (E) an effective quantity of an addition reaction retarder, in which the component (C) includes more than 90% by mass and no more than 100% by mass of an indium powder with an average particle size of 0.1 to 100 µm. Also provided is a heat conductive silicone cured product obtained by curing the above composition by heating at a temperature equal to, or greater than, the melting point of the indium powder. Further provided is an electronic device including an electronic component, a heat radiating member, and a heat conductive member including the above cured product disposed between the electronic component and the heat radiating member. Still further provided is a method of curing the above composition. Even further provided is a method of forming a heat conductive member between an electronic component and a heat radiating member. The above heat conductive silicone grease composition generates a suitably thin cured product with excellent thermal conductivity that prevents problems such as the contamination of components other than the coated component, and the leakage of oily materials from the product if used over extended periods.
