  • Patent number: 9739224
    Abstract: A turbocharger-equipped internal combustion engine includes an exhaust turbine, an exhaust filter, a differential pressure detector, an atmospheric pressure sensor, and an electronic control unit. The electronic control unit is configured to control the internal combustion engine such that accumulation amount of a particulate matter in the exhaust filter is regulated. The electronic control unit is configured to control the internal combustion engine such that the accumulation amount of the particulate matter in the exhaust filter is increased, when the pressure difference detected by the differential pressure detector is a lower limit or less. The electronic control unit is configured to set the lower limit such that the lower limit becomes a higher value as the atmospheric pressure detected by the atmospheric pressure sensor becomes lower.

  • Patent number: 7999941
    Abstract: A metal layer 13 made of Au or the like is formed on the upper surface of a transparent substrate 12. Dielectric layers 14a, 14b and 14c with different thicknesses are formed on the upper surface of the metal layer 13 (any one of the dielectric layers can have a thickness of 0) to form respective determination areas 15a, 15b and 15c. Further, different types of antibodies 22a, 22b and 22c are fixed on the upper surfaces of the respective dielectric layers 14a, 14b and 14c. Then, light is directed to the determination areas 15a, 15b and 15c, then signals of light reflected by the determination areas 15a, 15b and 15c are received, the light is dispersed, and analyses are performed on signals resulted from the light dispersion to detect the conditions of the surfaces of the respective determination areas, at the same time.

  • Patent number: 7906344
    Abstract: The metal fine particles 33 are sparsely fixed on the surface of the transparent substrate 32, and the acceptor 35 for attaching the specific ligand is immobilized on the transparent substrate 32 or the metal fine particles 33. The prism 36 is closely attached to the lower surface of the transparent substrate 32, and the excitation light enters the transparent substrate 32 through the prism 36. The incident light is totally reflected at the surface of the transparent substrate 32, and the evanescent light generated at the surface and the metal fine particles 33 locally plasmon resonate. As the evanescent light and the metal fine particles locally plasmon resonate, a strong electric field is enclosed in the vicinity of the metal fine particles.

  • Patent number: 7839508
    Abstract: A sensor chip has a metal layer formed on a surface of a substrate, where a plurality of microscopic concave part is formed in a measurement region of the surface of the metal layer. When light of linear polarization is irradiated onto the measurement region, local resonance electric field generates at opposing metal layer surfaces in the concave part. The reflected light thereof is received to measure reflectance. The light of linear polarization is irradiated so that the polarizing surface becomes orthogonal to the longitudinal direction of the concave part.

  • Patent number: 7501241
    Abstract: A method of mass-producing minute structures such as biochips, protein chips, quantum dots, and quantum chips involves arranging an antigen two-dimensionally on a board and arranging probes two-dimensionally facing the same direction so that the binding sites of the probes may bind to the antigen. An inorganic substance such as Ni is deposited on the board from the upper side of the probes by sputtering or evaporation to form a thin film layer and on the top surface of the flatly formed thin film layer, a supporting layer is formed by separating out the same inorganic substance using electrotyping. Then, by peeling the thin film layer and the supporting layer off of the board together, the mother stamper having cavities for the patterns of biomolecules is obtained.
