  • Publication number: 20220094138
    Abstract: A structure and a manufacturing method of an optical transmission module, in which output light of each of a first optical transmission unit and a second optical transmission unit is combined into one and transmitted through an optical fiber. In order to manufacture the optical transmission module, the first optical transmission unit and the second optical transmission unit are separately manufactured using a wafer-level packaging process and then are stacked. As a result, emission of generated heat is divided into a first heat sink installed in the first optical transmission unit and a second heat sink installed in the second optical transmission unit so that better heat dissipation efficiency is achieved than a conventional optical transmission module. In addition, a mounting area may also be reduced to ½ of the conventional module.

  • Patent number: 10392344
    Abstract: The present invention relates to a method for labelling fluorine-18, which is a radioisotope, and more specifically, to a method for labelling a [18F]fluoride in a method for preparing an organic [18F]fluoro compound by reacting an alkyl halide or an alkyl sulfonate with a [18F]fluoride, wherein a [18F]fluoride supported on a quaternary alkyl ammonium polymer support is eluted using a solution containing a metal salt or a quaternary ammonium salt with an adjusted pH, and a base is not additionally used. The present invention enables a labeling reaction without an additional base after precisely reflecting the concentration of a base absolutely necessary for the nucleophilic substitution of a [18F]fluoride or eluting a [18F]fluoride using a [18F]fluoride eluent with an adjusted pH, thereby stably obtaining a [18F]fluoride-labelled compound in a high yield, and is thus useful for production of fluorine-18-labelled radioactive medical supplies.
