Patent number: 6251670Abstract: 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.Type: GrantFiled: June 28, 1999Date of Patent: June 26, 2001Assignee: President of Kanazawa UniversityInventors: Tanihiro Yoshimoto, Hiroyuki Takamatsu

Patent number: 6195199Abstract: 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.Type: GrantFiled: October 27, 1998Date of Patent: February 27, 2001Assignee: Kanazawa UniversityInventor: Minoru Yamada
