  • Publication number: 20120103798
    Abstract: In one example embodiment, a protein-immobilized electrode is stably used for long time. In one example embodiment, a method of manufacturing the protein-immobilized electrode includes immobilizing cytochrome c552 having high stability to a chemically-stable gold electrode while maintaining electron transfer capability of the cytochrome c552. In one example embodiment, a self-assembled monolayer is formed on a gold electrode by using hydrophobic thiol and hydrophilic thiol. By dipping the gold electrode on which the self-assembled monolayer is formed in a cytochrome c552 solution, a protein-immobilized electrode in which a cytochrome c552 is immobilized to the gold electrode with the self-assembled monolayer in between is produced.

    Abstract: A color imaging element, a photosensor and a photoelectric transducer which use a protein and are capable of being stably used for a long time, and methods of manufacturing them are provided. A zinc-substituted cytochrome c552 is immobilized on a gold electrode with a self-assembled monolayer in between to form a blue-light photoelectric transducer. Alternatively, a cytochrome c552 is immobilized on a gold electrode with a self-assembled monolayer in between, and a fluorescent protein absorbing blue light is bonded to the cytochrome c552, thereby forming a blue-light photoelectric transducer. These photoelectric transducers each are used as a color imaging element or a blue-light photoelectric transducer of a photosensor.

  • Patent number: 7906219
    Abstract: A metallic glass laminate of the present invention is characterized in that a metallic glass layer of amorphous phase is formed on the substrate surface, and there is no continuous pore (pinhole) through the metallic glass layer. The metallic glass laminate is preferably obtained by solidification and lamination of at least part of the metallic glass powder in the molten state or in the supercooled liquid state on the substrate surface. Because of the dense metallic glass layer of homogenous amorphous phase, the functionalities of metallic glass such as corrosion resistance and wear resistance can be satisfactorily provided. A thick and a large-area metallic glass layer can be formed. The metallic glass layer can also be formed into various shapes within the supercooled liquid temperature range. In addition, a metallic glass bulk can be obtained by removing the substrate.

  • Publication number: 20100233018
    Abstract: Provided is an SnCu lead-free solder alloy which eliminates a drawback that an intermetallic compound excessively precipitates and the precipitate serves as nuclei to form dross to thereby cause soldering defects including a needle-like protrusion to occur, thus to satisfy all of the properties required for practical use. A lead-free solder alloy contains 0.1 to 1.5% by weight of Cu, not less than 0.01 and less than 0.05% by weight of Co, 0.05 to 0.5% by weight of Ag and 0.01 to 0.1% by weight of Sb, the remainder being Sn, or further contains 0.001 to 0.008% by weight of Ge, whereby the formation of dross is prevented, and thus the drawback that soldering defects including a needle-like protrusion occur is eliminated.

  • Patent number: 7793975
    Abstract: A passenger-seat airbag (32) includes a pair of left and right airbags (44, 46), and a root portion (48) that is connected to both of the left and right airbags (44, 46). When the passenger-seat airbag (32) is provided in a vehicle, an airbag folded portion (62) that forms the left and right airbags (44, 46) is positioned closer to the rear of the vehicle than the root portion (48) is, and a slack portion (49) that forms the root portion (48) is made upright along the airbag folded portion (62), and is positioned closer to the front of the vehicle than the airbag folded portion (62) is. Thus, the slack portion (49) is expanded and deployed toward a windshield earlier to form “a wall”. Then, the left and right airbags (44, 46) are stably deployed toward a passenger seat (toward the rear of the vehicle).

  • Publication number: 20090304888
    Abstract: There are provided a manufacturing method and a manufacturing apparatus for Baumkuchen for easily and properly suppressing shape distortion of the Baumkuchen caused in a manufacturing process thereof. In manufacturing the Baumkuchen by alternately repeating application of batter around the whole outer circumference of a spit and baking of the applied batter, the batter is scraped off outer circumferences of opposite end portions of the spit before baking only in early stage of manufacturing until the number of repetitions reaches a specified value. As a result, the number of cake layers formed at the opposite end portions of the Baumkuchen is reduced from that at the other portion and outside diameters of the opposite end portions are reduced from a normal outside diameter to thereby suppress partial increase in the outside diameter at the opposite end portions of the Baumkuchen caused by drooping of the batter at the end portions of the spit before baking.
