Publication number: 20070293340Abstract: An adjustable stick-like sport apparatus has an outer tube and a stick, the outer tube has an opening. The stick slidably mounted in the outer tube and has an extension portion formed in one end and inserted into the outer tube. Two nipping members encircle the extension portion, are engaged with the extension portion and are mounted slidably in the outer tube. When the user rotates the stick with the extension portion, the nipping members are stable relative to the extension portion. The sticks may extend out of or retract in the outer tube to vary a length of the adjustable stick-like sport apparatus. After the length is adjusted, reversely rotating the stick causes the two nipping members to tightly abut the outer tube to fix the length of the adjustable stick-like sport apparatus.Type: ApplicationFiled: June 17, 2006Publication date: December 20, 2007Inventor: Chen-Hua Cheng

Patent number: 6057601Abstract: The present invention discloses a new semiconductor ball grid array package for integrated circuits which have input and output counts higher than 250. The speed and performance characteristics of the semiconductor device contained in the package assembly are optimized while the packaging structure is simplified by utilizing only one dielectric layer and regular printed circuit board fabrication process. The complexities and higher cost for production of a multiple layer substrate for high-density interconnection configuration are thus resolved. The improved package assembly is achieved by implementing a segmented ring on one side of a substrate and a split plane on the other side thus forming a single layer substrate structure. The edges of the substrate are coated with metal layer to provide interlayer connections. The package assembly applies a cavity down configuration with an integrated heat spreader attached. The IC wire bonds within the cavity are sealed with an organic encapsulant.Type: GrantFiled: November 27, 1998Date of Patent: May 2, 2000Assignee: Express Packaging Systems, Inc.Inventors: John H. Lau, Tzyy Jang Tseng, Chen-Hua Cheng
