  • Patent number: 10614984
    Abstract: The present invention provides a fuse unit which facilitates a work such as inspection and a method of manufacturing the fuse unit. Disclosed is a method of manufacturing a fuse unit, which has a metal part including an input terminal and an external connection terminal and a connector part for attaching an external terminal C3 to the external connection terminal and is manufactured by integrating the metal part and a resin covering body by insert molding. In this manufacturing method, the metal part and the resin covering body are integrated by insert molding such that a distal end of the external connection terminal of the metal part protrudes from the resin covering body, and then, the connector part separate from the resin covering body is attached to the resin covering body so that the external connection terminal protruding from the resin covering body can be connected to the external terminal C3.

  • Patent number: 8038945
    Abstract: To provide a method for detecting a protein by immobilizing a protein on a protein array substrate at a high density with controlled orientation, irradiating the immobilized protein with ultraviolet light, visible light, or infrared light, and measuring the light not absorbed by the protein and further analyzing an interaction between the protein on the substrate and another protein and/or a compound other than proteins, a system used for the method, and to provide a protein array suitable for the system.

  • Publication number: 20100130721
    Abstract: This invention provides an immobilized protein bound to an immobilization carrier at a protein amino terminus via the sole ?-amino group of the protein comprising an amino acid sequence containing neither lysine residues nor cysteine residues represented by the general formula S1-R1-R2, wherein: the sequences are oriented from the amino terminal side to the carboxy terminal side; the sequence of the S1 portion may be absent, but when the sequence of the S1 portion is present, the sequence of the S1 portion is a spacer sequence composed of amino acid residues other than lysine and cysteine residues; the sequence of the R1 portion is the sequence of a subject protein to be immobilized and contains neither lysine residues nor cysteine residues; and the sequence of the R2 portion may be absent, but when the sequence of the R2 portion is present, the sequence of the R2 portion is a spacer sequence composed of amino acid residues other than lysine and cysteine residues.
