  • Publication number: 20110163625
    Abstract: A stator which may be employed in an electric rotating machine. The stator includes a stator winding which includes in-slot portions disposed in slots of a stator core. The in-slot portions are arrayed in each of the slots in a form of multiple layers aligned in a radial direction of the stator core. The stator winding is made up of a first winding and a second winding which are connected together through a joint. The first winding is defined by a portion of the stator winding between the joint and an end of the stator winding which is to be connected to an external. The second winding includes the in-slot portion placed within at least one of the slots as an outermost layer that is one of the layers placed most outwardly in the radial direction of the stator core. This results in a great decrease in leakage current.

  • Patent number: 6821749
    Abstract: The production of carotenoid is accomplished using a DNA molecule that encodes a polypeptide as obtained from Haematococcus pluvialis, Phaffia rhodozyma, or Saccharomyces cerevisiae, having isopentonyl pyrophosphate (IPP) isomerase activity, or DNA molecule having a nucleotide sequence that hybridizes thereto. In particular, one can introduce such a DNA molecule into a carotenoid-producing microorganism, culture the microorganism thus transformed, and then obtain carotenoids in the culture broth and cells.

  • Patent number: 5470971
    Abstract: Genes (and portions thereof) which are stress-inducible, e.g., by cold-shock which encode useful proteins. The proteins contribute to confer thermo-tolerance and/or contribute to confer low temperature tolerance to organisms, like eucaryotes or procaryotes. Typical genes encoding such proteins and homologous genes encoding proteins with equivalent properties are discussed. Nucleotide sequences encoding such proteins, recombinant replicable expression vehicles which comprise DNA constructs which encode such proteins and competent transformed organisms like eucaryotes are discussed. The production of valuable fermentation products and of biologically active proteins under conditions outside the normal or optimum physiological growth conditions are described.
