  • Patent number: 9926361
    Abstract: Disclosed is a method for producing proteins having factor VIII procoagulant activity in serum-free medium by in vitro culturing of mammalian cells, wherein the serum-free medium contains an inhibitor against the protease released from cultured cells. In accordance with this invention, the inhibitor can protect the cleavage of a target protein during cultivation and increase homogeneity of a target molecule, wherein the inhibitor can be a dextran sulfate. This invention also relates to a method of purifying target molecules from the culture medium containing both a target molecule and selected inhibitors by affinity chromatography.

  • Publication number: 20110316100
    Abstract: A micro electro mechanical systems (MEMS) microphone, and a method of manufacturing the MEMS microphone having an interval between a membrane and a back plate, the interval being correctly adjusted by forming the membrane and the back plate after an air-gap forming portion on a silicon substrate. Since the membrane and/or the back plate are/is formed by electroless plating, a sacrificial layer is easily planarized, and a residual stress is easily removed or controlled. The MEMS microphone includes a silicon substrate in which a back chamber is formed and on which an air-gap forming portion is formed above the chamber by etching the silicon substrate to a predetermined depth above the chamber; a membrane formed on the air-gap forming portion of the silicon substrate or the silicon substrate; and a back plate that is formed on the air-gap forming portion or the silicon substrate so as to be spaced apart from the membrane, wherein an air gap is formed between the membrane and the back plate.

  • Patent number: 6445898
    Abstract: A developing unit of a liquid electrophotographic printer includes a developing roller, for forming a development gap with a photoreceptor web where developer is filled and developing an electrostatic latent image formed on the photoreceptor web, a squeegee roller installed at the rear end of the developing roller for closely pressing the photoreceptor web to squeegee surplus developer, and a cleaning mechanism for removing toner particles of the developer adhering to a surface of the squeegee roller using an electrical force. Since the toner particles adhering to the squeegee roller are removed, contamination of a developed image is prevented and a clean image can be printed.
