  • Patent number: 9347944
    Abstract: Provided are a method and a kit for accurately and rapidly detecting ten types of targeting pneumonia bacteria: Streptococcus pneumoniae, Haemophilus influenzae, Mycoplasma pneumoniae, Chlamydophila pneumoniae, Legionella pneumophila, Klebsiella pneumoniae, Pseudomonas aeruginosa, Moraxella catarrhalis, methicillin-resistant Staphylococcus aureus (MRSA), and Staphylococcus aureus. A set of primer pairs directed to their respective target regions contained in the DnaJ gene, etc., of the ten types of pneumonia causative bacteria is designed for the ten bacterial strains and used to amplify gene products. A set of bacterial strain-specific probe pairs is further designed for the ten bacterial strains such that the probe pairs hybridize with the amplification products via sequences in the respective target regions differing from the sequences hybridized by the set of primer pairs.

  • Patent number: 7185349
    Abstract: The apparatus and methods of the present invention provide for a biaxial actuator, an optical pickup device, and an information optical processing device, in which the biaxial actuator is favorably mounted using a single structure. The mounting structure includes first fastening portions protruding from a bottom plate affixed to a substrate. Connecting portions are provided in the first fastening portions through first stress concentration points. The connecting portions are also provided in second fastening portions through second stress concentration points. A mounting portion is provided between the second fastening portions and yokes are formed on the bottom plate to establish a magnetic circuit. A fixing portion of the biaxial actuator is mounted on the mounting portion. By deforming each stress concentration point, a reference state of the objective lens can be determined at an arbitrary position.

  • Patent number: 6092994
    Abstract: A screw pump includes a casing having inlet and outlet ports and a pump rotor rotatably mounted in the casing and having screw threads communicating with said inlet and outlet ports. The pump rotor is rotated by a reversible speed-controllable motor, typically a DC brushless motor, mounted in the casing to deliver a liquid such as a chemical solution from the inlet port through a liquid passage defined by the screw threads to the outlet port.
