  • Patent number: 9735551
    Abstract: A surge absorber and a manufacturing method thereof are disclosed. Since a ceramic material with excellent mechanical strength is used to form a ceramic tube and the ceramic tube is joined to sealing electrodes by use of brazing rings according to the method of manufacturing the surge absorber, durability of the surge absorber is considerably improved. Since the ceramic tube is completely sealed, the surge absorber may be stably used at a high voltage.

  • Patent number: 9670240
    Abstract: Provided are novel cyclic phosphinate derivatives and a method of preparing the same, and more particularly, cyclic phosphinate derivatives including benzoxaphosphole oxide derivatives and benzoxaphosphorin oxide derivatives, and a method of preparing the same. The cyclic phosphinate derivative according to the present invention may have pharmacological and physiological activities, be used as the basic skeleton of the natural material, and be used in development of a new drug, and synthesis of various medicines. In addition, with the method of preparing a cyclic phosphinate derivative according to the present invention, various cyclic phosphinate derivatives may be prepared with high yield through a simple synthetic process by performing an intramolecular carbon-oxygen coupling reaction on the phosphinic acid derivative in the presence of a palladium (Pd) catalyst, an oxidant, and a base.

  • Patent number: 7610311
    Abstract: A method for quantifying plant resource using a GIS is disclosed, in which it is possible to more efficiently quantify plant resources with less manpower, time and cost using a GIS when quantifying plant resources in a certain region. In the method, a sample group is extracted from mother groups having a plurality of distribution maps having a plurality of environment factors including IMI as attribute data, the IMI being obtained through a GIS preprocess. A relative model formula is obtained between a plant resource real measurement value of the sample group and an environment factor real measurement value and is related with the distribution map of the mother group, and the distribution maps are overlapped for thereby forming a plant resource estimation distribution map of the mother group.
