    摘要: An optical amplifier having a two-stage construction using an erbium doped fiber (EDF) as a gain medium. The erbium dopant concentration is 1000 ppm, and the unsaturated absorption coefficient of the signal beam at 1550 nm is 1 dB/m. The length of the EDF 14-8 is 10 m, and the length of the EDF 14-12 is 70 m. The excitation light sources 14-6 and 14-10 are semiconductor lasers of 1.53 &mgr;m, and the excitation light power is 100 mW. Multiplexers 14-7 and 14-11 are inductive multi-layer film filters, and the gain equalizer 14-4 is a Fourier filter. The peak loss of the Fourier filter is 17 dB. The gain of the EDF 14-8 is 25 dB, and the gain of the EDF 14-12 is 15 dB. Two optical isolators are installed on a pre-stage amplifier, and one on a post-stage amplifier in order to prevent laser oscillation.

    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.
