    摘要: L-glutamine is purified by concentrating a fermentation liquor containing at least 40 g/l or more of L-glutamine, or a solution obtained therefrom by filtering off microbial cells, at pH 5.6.+-.0.5, or by cooling the fermentation liquor or the solution after concentration or without concentration at a temperature in the range of 2.degree. to 30.degree. C., thereby giving a slurry of L-glutamine crystals of 70 g/l or higher concentration; (2) separating the crystals from the mother liquor and then dissolving the separated crystals in a water; and (3) bringing the solution thus obtained into contact with an OH-type anion-exchange resin, thereby removing impurities through adsorption.

    摘要: The present invention provides an axial-flow fan capable of entirely cooling an object to be cooled even when the distance between the object to be cooled and an air discharge opening of the axial-flow fan is short. A plurality of stationary blades 11A to 11E are disposed at intervals in a rotating direction of a rotor and located inside an air discharge opening 16 of an air channel 19. Each of the plurality of stationary blades 11A to 11E has an external end portion 11a connected to an inner wall portion of a fan housing 3, an internal end portion 11b connected to a peripheral wall portion 11B of a motor case 10, a discharge-side edge portion 11c formed between the external end portion 11a and the internal end portion 11b and located at a side of the air discharge opening 16, and a suction-side edge portion 11d formed between the external end portion 11a and the internal end portion 11b and located at a side of the air suction opening 14. An outer surface of the bottom wall portion 10A of the motor case 10 is located closer to a side of the air suction opening 14 than the discharge-side edges 11c of the plurality of stationary blades 11A to 11D are located.

    摘要: A brushless motor stator is provided that may be applied to a plurality of types of motors having different rotational speeds, merely by providing one type of a circuit substrate. A pair of fitting convex portions that project radially outside of a virtual circle centering on a center line C are formed on one insulator divided body of a slot insulator. Three pairs of diagonally located fitting concave portions are formed in an inner circumferential wall portion surrounding a through-hole of a circuit substrate. The pair of fitting convex portions of the one insulator divided body are fitted in one of the three pairs of fitting concave portions. With this, a positional relationship between three hall elements and stator magnetic poles is selected, corresponding to the speed range of a motor to be used.
