  • Publication number: 20240262019
    Abstract: A molding apparatus includes a mold and a wedge structure. The mode has a first mold member and a second mold member configured to be movable towards the first mold member along a first direction, the first and second mold members cooperating in use to form a molding cavity for encapsulating an electronic component. The wedge structure has a first wedge member attached to the second mold member and a second wedge member configured to be in contact with the first wedge member and movable in a second direction perpendicular to the first direction to adjust contacting portions between a first contacting surface of the first wedge member and a second contacting surface of the second wedge member, thereby biasing the second mold member towards the first mold member to form the molding cavity, wherein at least one of the first and second contacting surfaces includes a first protection film attached thereon.

  • Patent number: 6916610
    Abstract: Generation of longer cDNA fragments from SAGE tags for gene identification (GLGI) is disclosed. This method converts SAGE tags, which are about 10 base pairs in length, into their corresponding 3? cDNA fragments covering hundred bases. This added information provides for more accurate genome-wide analysis and overcomes the inherent deficiencies of SAGE. The generation of longer cDNA fragments from isolated and purified protein fragments for gene identification is also disclosed. This method converts a short amino acid sequence into extended versions of the DNA sequences encoding the protein/protein fragment and additional 3? end sequences of the gene encoding the protein. This additional sequence information allows gene identification from purified protein sequences. The invention also provides a high-throughput GLGI procedure for identifying genes corresponding to a set of unidentified SAGE tags.

  • Patent number: 6594651
    Abstract: A method, apparatus, and an article of manufacture for parallel execution of SQL operations from within user defined functions. One or more embodiments of the invention provide the user defined function (UDF) with a C++ class (hereinafter referred to as “dispatcher”) that can take an SQL query and start parallel execution of the query. The query is optimized and parallelized. The dispatcher executes the query, sets up the communication links between the various operators in the query, and ensures that all the results are sent back to the data-server that originated the query request. Further, the dispatcher merges the results of the parallel execution and produces a single stream of tuples that is fed to the calling UDF. To provide the single stream to the calling UDF, one or more embodiments of the invention utilize a class that provides the UDF with a simple and easy-to-use interface to access the results of the nested SQL execution.
