  • Patent number: 6251670
    Abstract: An object of the present invention is to provide a method of enabling perfusion culture efficiently and simply by agglutinating cells with Lectin, which is a naturally-occurring agglutinin, thereby separating the cells and the culture medium. According to the method of the present invention, lectin is added to a culture medium to quickly agglutinate and precipitate the cells, thereby separating the culture medium and the cells. Hence, it is easy to remove old culture medium and replenish with fresh culture medium. Accordingly, if the method of the present invention is used, the perfusion culture is performed automatically and on an industrial scale.

  • Patent number: 6195199
    Abstract: Within a vacuum vessel 10, there are arranged an electron gun 2 emitting an electron beam and an amplification part 3 which amplifies incident light 7 by means of the energy of the electron beam. The amplification part 3 is formed by two wave-like mirrors 4 and 5 made of a metal such as Ag or a multi-layer structure of dielectric materials, said mirrors being separated from each other to constitute not only an electron beam travelling part, but also a light input part 4a, 5a, a light amplifying part 4b, 5b and a light output part 4c, 5c arranged in this order viewed in a travelling direction of the electron beam. The light is made incident upon the light input part at a given incident angle, and propagates along the wave-like or zigzag optical waveguide within the light amplifying part by repeating reflections. Therefore, the wavenumber of the light is increased, and the light is amplified in a unidirectional manner by the energy of the electron beam.

  • Patent number: 5240382
    Abstract: A converged magnetic flux type electro-magnetic pump in which plural circular conductor plates provided with slits reaching peripheries from central holes in the plates and plural exciting spiral coils are alternately stacked with respect to each other and individually surrounded by magnetic frames. A high density traveling magnetic flux is generated by eddy currents concentrated around the central holes of the circular conductor plates in response to the application of a multiphase alternating voltage in a non-magnetic pipe passing through the central holes with a cylindrical iron core inserted in the pipe, so as to convey high temperature molten metal such as molten sodium used for refrigerating a high speed breeder reactor. The thickness of the central portions of the circular conductor plates is greater than the remainder of the plates, so as to form a radial T-shaped cross-section.
