  • Publication number: 20140020526
    Abstract: A lathe includes a machine support, a work table, a moving device and a feeding device. The work table is rotatably positioned on the machine support for driving a workpiece placed on the work table to rotate. The moving device is movably mounted, slidably on the machine support along a first direction above the work table. The feeding device is slidably positioned on the moving device along a second direction vertical to the first direction, the feeding device includes a cutter. The feeding device drives the cutter backwards and forwards under precise control at high speed along a third orthogonal direction for machining the workpiece.

  • Publication number: 20140020536
    Abstract: A feeding device includes a tool holder, a cutter, a feeding mechanism and a mounting seat. The cutter is positioned on the tool holder. The mounting seat has at least one guiding portion. The tool holder is slidably engaged with the at least one guiding portion. The feeding mechanism includes at least two drivers. Each driver includes a forcer and a stator. The forcers are mounted in the mounting seat, the stators are fixedly positioned on the tool holder. Interactions between alternating magnetic fields produced by the forcers and magnetic fields produced by the stators drive the tool holder and the cutter to backwards and forwards under precise control along the guiding portion.

  • Publication number: 20140023877
    Abstract: A workpiece has non-rotary curved surface and edges. The workpiece is machined by a lathe. The lathe includes a cutter and a work table under the cutter. The worktable is configured for driving the workpiece to rotate. The non-rotary curved surface of the workpiece has a good finish because the cutter moves along a spiral cutting path on the workpiece at high speed continuously during the machining.

  • Publication number: 20100311779
    Abstract: A method for preparing dehydrocavidine, dehydroapocavidine and their respective composition is provided. The composition is first prepared by isolating and purifying the quaternary ammonium alkaloid components from the medicinal plant “Yan Huang Lian” (Corydalis saxicola Bunting) through the processes of solvent extraction, water-phase organic extraction, crystallization and recrystallization, and then drying to obtain said composition containing dehydrocavidine and dehydroapocavine. When necessary, the composition or their crude extracts can be separated by chromatography to obtain dehydrocavidine or dehydroapocavidine. Dehydrocavidine, dehydroapocavidine or their respective composition can be used in manufacturing medicines for treating viral hepatitis, hepatic injury, influenza, AIDS, tumors or arrhythmia.

  • Publication number: 20090170930
    Abstract: A method for promoting differentiation of clonogenic neural stem cells (NSCs), comprising administering to a patient in the need of such promoting a coumarin compound represented by formula I or by formula II. The representative coumarin compounds include 7-hydroxycoumarin, daphnoretin, scopoletin, edgeworin, aesculetin and esculetin-6-?-D-glucopyranoside. The coumarin compounds showed significant activity of directing the differentiation of NSCs in pharmacological test and thereof could be used to prepare drugs to direct NSCs differentiated to oligodendrocyte progenitor cells (OPCs) for the treatment of demyelinating diseases or spinal cord injury. The drug could be a pure coumarin compound or a pharmaceutical composition comprising a therapeutical dose of a coumarin compound as active ingredients and a pharmaceutically-acceptable carrier. The content of the active ingredients in the pharmaceutical composition is between 0.1% and 99.5% by weight.
