  • Publication number: 20230134880
    Abstract: It is aimed to provide a laminated varistor capable of reducing stray capacitance to occur between an internal electrode and an external electrode, and also capable of reducing a variation in the stray capacitance due to a variation in the external electrode. A laminated varistor of the present disclosure has external electrodes on first end surface, second end surface, and first side surface of sintered body. No external electrode is provided on second side surface opposite to first side surface. Varistor regions in which internal electrodes overlap each other in a laminating direction are provided at positions closer to second side surface than to first side surface.

  • Publication number: 20220310291
    Abstract: A sintered body that includes semiconductor ceramic layers and an internal electrode which are alternately stacked on one another is prepared. A first external electrode is formed on a side surface of the sintered body such that the first external electrode is connected to the internal electrode. An insulating layer is formed on a surface of the sintered body by applying a glass coating over an entire of the sintered body having the formed first external electrode. The insulating layer is exposed from the first external electrode. A second external electrode is formed on the first external electrode. This method provides the produced multilayer electronic component with a stable electric connection between the internal electrodes and the external electrodes.

  • Patent number: 10011881
    Abstract: [PROBLEM TO BE SOLVED] An object of the present invention is to provide a novel tumor marker and use thereof. In more detail, the present invention provides a novel tumor marker, a method for measuring said tumor marker and a measurement kit, a method for detecting cancer using the same, a kit for detecting cancer, a method for screening a preventive and/or therapeutic agent for cancer, as well as a medicament such as cancer vaccine. [SOLUTION] According to the present invention, a method for measuring an alternative splicing variant of OATP1B3 mRNA in a sample to be examined is provided. Said measurement method comprises measuring mRNA comprising a nucleotide sequence represented by SEQ ID NO: 1 in the sequence listing table in a sample to be examined isolated from living organism with differentiation from a mRNA comprising a nucleotide sequence represented by SEQ ID NO: 2. Said measurement method is useful for detecting cancer or screening a preventive and/or therapeutic agent.
