  • Antenna apparatus for base station and adapter thereof
    Patent number: 11962073
    Abstract: The present disclosure relates to an antenna apparatus for a base station and an adapter thereof and particularly comprises: an antenna module vertically installed to be spaced forward from a support pole by a predetermined distance so as to have a distancing space therebetween; an RRH installed on the antenna module to be positioned in the distancing space, wherein one of the upper end and the lower end thereof is hinge-coupled to the antenna module and the other of the upper end and the lower end thereof is attached to or detached from a part of the antenna module to enable electrical signal connection or disconnection while being rotated around the hinge; and an adapter for mediating the electrical signal connection and disconnection between the antenna module and the RRH. Therefore, the present disclosure provides advantages of reducing installation time and installation costs.

  • Microorganism producing L-methionine precursor and method of producing L-methionine and organic acid from the L-methionine precursor
    Patent number: 9029105
    Abstract: The present invention relates to a method for producing L-methionine, comprising: i) culturing an L-methionine precursor-producing microorganism strain in a fermentation solution, so that the L-methionine precursor accumulates in the solution; and ii) mixing a converting enzyme and methylmercaptan or its salts with at least a portion of the solution to convert the accumulated L-methionine precursor into L-methionine, as well as to microorganism strains used in each step.
