  • Patent number: 8758741
    Abstract: A transformant is prepared to insert at least a gene expression cassette comprising a gene involved in the synthesis of 2-deoxy-scyllo-inosose into E. coli as host cells. A 2-deoxy-scyllo-inosose is synthesized from D-glucose, oligosaccharide, polysaccharide, starch and rice bran, using the transformant. A culture solution containing the 2-deoxy-scyllo-inosose is treated with a mixed bed or double bed type column comprising a hydrogen form of strong acidic cation exchange resin and an organic ion form of basic anion exchange resin. The 2-deoxy-scyllo-inosose as purified is reacted with trimethoxymethane to convert into 2-deoxy-scyllo-inosose dimethylketal, and the dimethylketal is crystallized and purified. Then, DOI is highly purified through hydrolyzing the dimethylketal in the presence of acid.

    Abstract: A laminated rotor core (36) wherein permanent magnets (47) are inserted in respective magnet insertion holes (46) is disposed between and pressed by an upper die (37) and a lower die (29). The upper die (37) has resin reservoir pots (50) provided above the laminated rotor core (36) and at positions corresponding to the respective magnet insertion holes (46). Raw resin material put in the resin reservoir pots (50) is heated by the upper die (37). Subsequently, the resin material in a liquefied state is ejected from the resin reservoir pots (50) by plungers (52) that are inserted and moves vertically in the resin reservoir pots (50) and is directly filled in the magnet insertion holes (46). Consequently, the respective magnet insertion holes (46) are filled with the resin material more evenly and highly reliable products can be supplied at low cost.
