  • Patent number: 7582379
    Abstract: Provided is a secondary battery of an assemble-type structure having a cell body including an electrode assembly of cathode/separator/anode sealed therein; and a cap assembly including a protection circuit electrically connected to the cell body so as to control overcharge, overdischarge and overcurrent of the battery and a cap housing covering an upper part of the battery, and being detachably coupled to the cell body. Since the cap assembly including the protection circuit and cap housing is assembled detachably from the cell body and electrically connected to and also can be physically firmly fixed to one another, provided are effects capable of greatly reducing the manufacturing process steps of the battery, and solving all the problems associated with use of battery cases and insert injection molding.

  • Patent number: 6428824
    Abstract: An isolated composition obtained by extracting Lepidium meyenii roots is provided. The composition is substantially free of cellulose and comprises between about 5% and about 9% of benzyl isothiocyanate, between about 1% and about 3% of Lepidium sterol component, between about 20% and about 30% of Lepidium fatty acid component, and about 10% or more of macamide component. The composition is prepared by a process which comprises contacting Lepidium meyenii roots with a first aqueous solvent of about 90% vol-% or more water, then separating the residual Lepidium meyenii root material from the first contacted aqueous solvent, then contacting the residual Lepidium meyenii root material with a second aqueous solvent which comprises a mixture of an alcohol and water having about 90 vol-% alcohol or more to form a liquor, and then finally concentrating the liquor to obtain the composition. The composition can be used for treating cancer and sexual dysfunction.
