  • Patent number: 10978253
    Abstract: A capacitor circuit (capacitor device 20, 30, 34, 50) in which a plurality of capacitors (41 to 45) are connected to each other is included, one or two or more capacitors (overvoltage short-circuiting capacitors 40, 40a, 40b, 40c, 40d) in the capacitor circuit have a dielectric breakdown voltage made lower than that of another capacitor, and the one or two or more capacitors having the lower dielectric breakdown voltage are subjected to dielectric breakdown due to application of an overvoltage earlier than the other capacitor so that the capacitor circuit is short-circuited. As a result, the safety of the capacitor device and a device connected thereto can be enhanced.

  • Patent number: 8367702
    Abstract: As a result of extensive studies on NAD(P)H oxidase inhibitors, the present inventors found that a quinolone derivative having, at the 2-position, an alkyl group substituted with a heteroatom or the like has an excellent NAD(P)H oxidase inhibitory activity, and accomplished the present invention. The compound of the present invention has a reactive oxygen species production inhibitory activity based on the NAD(P)H oxidase inhibitory activity, and therefore can be used as an agent for preventing and/or treating diabetes, impaired glucose tolerance, hyperlipidemia, fatty liver, diabetic complications and the like.

  • Publication number: 20120229118
    Abstract: A reactor includes a ringed core and a magnetic excitation coil. The ringed core includes a plurality of core blocks made of a magnetic material which are connected in a ring through gaps. The magnetic excitation coil is wound around the ringed core. The ringed core has a magnetic leg region around which the magnetic excitation coil is wound and a yoke portion region where the magnetic excitation coil is not wound. A length of the gap in the magnetic leg region is smaller than a length of the gap in the yoke portion region. Positions of gaps or magnetic excitation coil may be modified. A power converter using the reactor is also disclosed.

  • Patent number: 7982049
    Abstract: To provide novel crystals useful as an ingredient for the production of a diabetes remedy. The invention is concerned with ?-form crystal and ?-form crystal of (R)-2-(2-aminothiazol-4-yl)-4?-[2-[(2-hydroxy-2-phenylethyl)amino]ethyl]acetanilide. The ?-form crystal does not exhibit hygroscopicity and has stability such that it can be used as a medicine, and is useful for mass synthesis in the industrial production. The ?-form crystal does not relatively exhibit hygroscopicity and is also useful as a production intermediate of the ?-form crystal.
