    Abstract: A porous dielectric film for use in electronic devices is disclosed that is formed by removal of soluble nano phase porogens. A silicon based dielectric film having soluble porogens dispersed therein is prepared by chemical vapor deposition (CVD) or by spin on glass (S.O.G.). Examples of preferable porogens include compounds such as germanium oxide (GeO 2 ) and boron oxide (B 2 O 3 ). Hot water can be used in processing to wet etch the film, thereby removing the porogens and providing the porous dielectric film. The silicon based dielectric film may be a carbon doped silicon oxide in order to further reduce the dielectric constant of the film. Additionally, the porous dielectric film may be treated by an electron beam to enhance the electrical and mechanical properties of the film.

    Abstract: A locking nut assembly (10) including a bearing nut (12) having a plurality of external serrations (30), a shaft nut (14) having a plurality of external serrations (60), and a locking collar (16) having a plurality of internal serrations (92). The bearing nut (12) and the shaft nut (14) are threadedly installed on a shaft assembly (20) having an impeller (106), a bearing (1 16), and a spline adapter (118) installed within the impeller (106). The plurality of serrations (30) of the bearing nut (14) align with the plurality of serrations (60) of the shaft nut (14) when they are installed on the impeller (106). The locking collar (16) is installed on the bearing nut (12) and the shaft nut (14) so that the aligned plurality of serrations (30) of the bearing nut (12) and the plurality of serrations (60) of the shaft nut (14) engage the plurality of serrations (92) of the locking collar (16). The locking collar (16) is retained on the bearing nut (12) and shaft nut (14) by a retaining ring (18).
