Patent number: 7527488Abstract: The present invention relates to apparatus and methods of vibration. In particular, the present invention relates to apparatus and methods of vibration for tooling in a structure, such as, for example, a fuselage. In one implementation, the tooling comprises at least two conductors that create a force to vibrate the media in the tooling, which improves the compaction of the media in the tooling and the extraction of the media from the tooling. Other implementations may be used for compaction and/or extraction of the media in the tooling.Type: GrantFiled: April 6, 2007Date of Patent: May 5, 2009Assignee: Toyota Motor Sales USA, Inc.Inventor: Curtis Longo

Patent number: 7523914Abstract: A high-hardness and corrosion-tolerant integrated circuit packing mold comprises a package mold including at least one filling channel, at least one mold cavity, and at least one channel between the mold cavities; a protecting layer deposited upon surfaces of the package mold and the protecting layer being an amorphous coating layer. In one case, the protecting layer is a graded layer including an amorphous coating layer and a middle layer. In a second case, the protecting layer is a multiplayer structure formed by at least one amorphous coating layer and at least one polycrystal coating layer. In the third case, the protecting layer is a compound structure formed by distributing polycrystal material into an amorphous coating layer.Type: GrantFiled: July 1, 2005Date of Patent: April 28, 2009Inventors: Yin Yu Chang, Da Yung Wang, Shien Chen Liu
