  • Patent number: 11935703
    Abstract: A multilayer electronic component has a body and a non-conductive resin layer. The non-conductive resin layer includes a body cover portion disposed in a region of an external surface of the body in which an electrode layer of an external electrode is not disposed, and an extending portion extending from the body cover portion between the electrode layer and a conductive resin layer of the external electrode, to thereby suppress arc discharge, improve bending strength, and improve moisture resistance.

  • Publication number: 20110223318
    Abstract: The present invention relates to a method for introducing a functional group to the surface of a material. The present invention provides a method for introducing a mixture of a lipid and a compound containing a functional group to the surface of a material. The method, for example, comprises the steps of: mixing a lipid with a compound containing a functional group to form liposome; and introducing the liposome to the surface of a material. The method enables a simple process and the reduction of processing time, compared with conventional chemical surface treatment methods. Additionally, the method ensures high efficiency and reproducibility when fixing a receptor on the surface of a material. Furthermore, the method does not need to use various reagents and is simple, so people unfamiliar with chemistry can utilize the method easily.
