    摘要: A testing system for testing flatness of a surface of a workpiece includes a testing apparatus (10) and a processor (20). The testing apparatus includes a testing box (12) and a measuring apparatus (14). The testing box includes a plurality of holders (122); the holders define a datum plane. The measuring apparatus comprises a plurality of movable testing poles (142) extending out of the testing box and a plurality of gauges (141) configured for measuring distance of the testing poles retracting into the testing box. Ends (1421) of the testing poles away from the testing box are located at the datum plane and configured for supporting the surface of the workpiece thereon to allow the gauges measuring retracting distance of the testing poles under the pressure of the workpiece. The retracting distance of the testing poles is equal to distances between testing points on the surface of the workpieces and the datum plane. The processor is connected to the testing apparatus for receiving and processing testing data that are converted from the retracting distance of the testing poles measured by the gauges.

    摘要: Extraction of semantic information and the generation of semantic attributes allows for improved organization and management of data. Semantic attributes are automatically generated and eliminate the need for manual entry of attribute information. A semantic file network may further be constructed based on similarities between files that are based on the semantic attribute information. Semantic links representing a semantic relationship may be built between similar or relevant files. In addition, user operations and user operation patterns may also be considered in building the file network. Semantic attributes and information may further facilitate browsing the file systems as well as improve the accuracy and speed of queries.

    摘要: The present invention provides a self lubricating magnetic recording system that delivers lubricant molecules from a gas phase to the surface of recording media at a sufficient rate to cover the exposed media before it can interact with the writing transducer. The environment around the media surface includes lubricant vapor, and when the lubricant film is removed from the disc surface, e.g., upon heating of the medium, it is replaced by adsorption from the surrounding vapor. The lubricant is thus replenished by delivering lubricant from the vapor phase.
