    摘要: This centrifugal blood pump apparatus includes an impeller provided in a blood chamber, a first permanent magnet provided in one surface of the impeller, and a second permanent magnet provided in an inner wall of the blood chamber, for attracting the first permanent magnet. The attractive force between the first permanent magnet and the second permanent magnet on the opening side of a sidewall of the blood chamber is set to be smaller than the attractive force between the first permanent magnet and the second permanent magnet on the opposite side of the opening. As a result, inclination of the impeller with respect to a dividing wall during pump operation can be prevented.

    摘要: It is an object of the present invention to provide a stable production process for a melt-blown nonwoven fabric comprising thin fibers and having extremely few thick fibers [number of fusion-bonded fibers] formed by fusion bonding of thermoplastic resin fibers to one another, and an apparatus for the same. The present invention relates to a melt-blown nonwoven fabric comprising polyolefin fibers and having (i) a mean fiber diameter of not more than 2.0 μm, (ii) a fiber diameter distribution CV value of not more than 60%, and (iii) 15 or less fusion-bonded fibers based on 100 fibers; a production process for a melt-blown nonwoven fabric characterized by feeding cooling air of not higher than 30° C. from both side surfaces of outlets of slits 31 from which high-temperature high-velocity air is gushed out and thereby cooling the spun molten resin; and a production apparatus for the same.
