Abstract: An automotive boot for use with a connection such as a constant velocity joint includes a separate boot and a separate bushing. The bushing has an internal configuration which is tri-lobed to contact the surface of one of the mechanical components encapsulated by the boot.   The internal surface of the skirt of the boot and the corresponding external surface of the bushing each contain interlocking components, preferentially these are ribs and corresponding grooves. The bushing is slightly larger than the boot to produce an interference fit and the ribs are slightly radially longer than the grooves are deep to deform the ribs when received in the grooves, thereby retaining the bushing without tightening the typical hose clamp and providing an effective seal between the bushing and boot to retain lubricants within the boot in use.

Title: Fabrication of gallium nitride layers by lateral growth
Inventor: RAJAGOPAL PRADEEP
IPC: H01L33/32
Filed: 1999-11-23
Granted: 2009-06-02
Abstract: An underlying gallium nitride layer (104) on a silicon carbide substrate (102) patterned with a mask (109) that includes an array of openings therein, and is etched through the array of openings to define posts (106) in the underlying gallium nitride layer and trenches (107) therebetween. The posts each include a sidewall (105) and a top having the mask thereon. The sidewalls of the posts are laterally grown into the trenches to thereby form a gallium nitride semiconductor layer (108a). During this lateral growth, the mask prevents nucleation and vertical growth from the tops of the posts. Accordingly, growth proceeds laterally into the trenches, suspended from the sidewalls of the posts. The sidewalls of the posts may be laterally grown into the trenches until the laterally grown sidewalls coalesce in the trenches to thereby form a gallium nitride semiconductor layer. The lateral growth from the sidewalls of the posts may be continued so that the gallium nitride layer grows vertically through the openings in the mask and laterally overgrows onto the mask on the tops of the posts, to thereby form a gallium nitride semiconductor layer (108b). The lateral overgrowth can be continued until the grown sidewalls coalesce on the mask to thereby form a continuous gallium nitride semiconductor layer.  Microelectronic devices (110) may be formed in the continuous gallium nitride semiconductor layer.
