  • Patent number: 7897089
    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.

  • Patent number: 7897805
    Abstract: A polyisocyanate production method that can allow effective use of hydrogen chloride produced secondarily in a polyisocyanate production process, while allowing reduction of environmental burdens, and a polyisocyanate production system for performing the polyisocyanate production method. After chlorine is allowed to react with carbon monoxide to produce carbonyl chloride in a carbonyl chloride producing reactor, the carbonyl chloride produced in the carbonyl chloride producing reactor is allowed to react with polyamine in an isocyanate producing reactor to produce polyisocyanate. Then, after hydrochloric gas produced secondarily in the isocyanate producing reactor is purified in a hydrogen chloride purifying column, the purified hydrochloric gas is oxidized in a hydrogen chloride oxidizing reactor to produce chlorine.
