Patent number: 5943662Abstract: A method and a system for causing a neural circuit model to learn typical past control results of a process and using the neural circuit model for supporting an operation of the process. The neural circuit model is caused to learn by using, as input signals, a typical pattern of values of input variables at different points in time and, as a teacher signal, its corresponding values of the control variable. An unlearned pattern of input variables is inputted to the thus-learned neuron circuit model, whereby a corresponding value of the control variable is determined. Preferably, plural patterns at given time intervals can be simultaneously used as patterns to be learned.Type: GrantFiled: March 31, 1994Date of Patent: August 24, 1999Assignee: Hitachi, Ltd.Inventors: Kenji Baba, Ichiro Enbutsu, Shoji Watanabe, Hayao Yahagi, Fumio Maruhashi, Harumi Matsuzaki, Hiroshi Matsumoto, Shunsuke Nogita, Mikio Yoda, Naoki Hara

Patent number: 5403735Abstract: In order to investigate an object, such as a culture of micro-organisms, the object is repeatedly captured at two different magnifications by a suitable image pick-up device. The images at the two different magnifications are then analysed by a suitable picture image recognition device and the results of the repeated analysis are compared, thereby to derive a measurement of the change in the object with time. Thus, for a culture of micro-organisms, the number of cells can be determined at one magnification and the number of microscopic spherical bodies can be determined at another magnification, to obtain a measure of the activity of the culture. Preferably, one or more conditions of the object are then controlled on the basis of the measurement of change.Type: GrantFiled: July 24, 1991Date of Patent: April 4, 1995Assignee: Hitachi, Ltd.Inventors: Fumio Maruhashi, Nobuko Nishimura, Ryoichi Haga, Harumi Matsuzaki, Ryusei Nakano

Patent number: 5227066Abstract: A centrifugal separation method for living cells is disclosed in which a cell containing solution is charged in a rotor chamber confined by a steam pressure-resistant wall. A rotor having septa is disposed in the rotor chamber. The septa are rotatable in the same direction at the same angular velocity as the rotor while at least part thereof is immersed in a solution in the rotor when cells are to be centrifuged from the cell-containing solution. After the cells are separated and adhered to the inner surface of the rotor, a supernatant in the rotor is discharged form the rotor. Then a fresh cultivating medium is introduced into the rotor, and the septa and the rotor are rotated at mutually different angular velocities while at least part of the septa is immersed in the fresh medium in the rotor. As a result, the cells are again suspended in the fresh medium.Type: GrantFiled: June 27, 1991Date of Patent: July 13, 1993Assignee: Hitachi, Ltd.Inventors: Masahiko Ishida, Ryoichi Haga, Harumi Matsuzaki

Patent number: 5166067Abstract: A culturing method and system are disclosed in which a cell culture broth in withdrawn from a culturing apparatus to a filteration apparatus. The withdrawn broth in brought into contact with a membrane for precision filteration. Then a non-toxic gas is brown into the broth, while filtering the broth to separate the cells and breaking foams occurring on the surface of the broth due to gas bubbling. The separated cells are returned to the vessel and the filterate is withdrawn from the filteration apparatus.The method and system have such advantages that a perfusion culture of a long period of time can be realized because the clogging of the filteration membrane is effectively prevented.Type: GrantFiled: November 29, 1989Date of Patent: November 24, 1992Assignee: Hitachi, Ltd.Inventors: Masahiko Ishida, Ryoichi Haga, Harumi Matsuzaki

Patent number: 5162204Abstract: An apparatus for culturing animal cells, includes a diagnosis system to make it possible to diagnose by measuring sizes of the cells by means of image processing while a system of culturing the animal cells is cut off from the outside of the apparatus system, a control system to control the culture conditions of a culturing cistern on the basis of a result of the diagnosis, and a culture medium regenerating system to remove waste contents in a culture medium. In the apparatus of this invention, the culture system and diagnosis system are cut off from the outside of the apparatus system. Therefore, no infection of miscellaneous microorganism, etc., occurs, nor does consumption of valuable cells and products occur. Further, since it is possible to easily obtain data of the proportions of division potential-possessing cells and living cells, the environmental factors to the culturing cistern can be easily and instantly controlled based on the data, and therefore, the culturing efficiency can be enhanced.Type: GrantFiled: May 4, 1989Date of Patent: November 10, 1992Assignee: Hitachi, Ltd.Inventors: Harumi Matsuzaki, Ryoichi Haga, Yuusaku Nishimura, Kenji Baba, Fumio Maruhashi, Nobuko Nishimura, Masahiko Ishida, Setuo Saitoh

Patent number: 4953694Abstract: A distilling apparatus includes an evaporation section which heats raw water and causes the generation of vapor from said raw water, and a hydrophobic porous film through which the thus generated vapor is filtered. Because vapor separated from the raw water is supplied to one surface of the hydrophobic porous film, the proportion of the vapor relative to the fluid supplied to that surface of the film can be increased, thereby enabling the efficient filtering of a large amount of vapor through the film. In addition, because the temperature of condensed water obtained by cooling the vapor can be kept in the vicinity of the boiling point thereof, any gases and volatile substances contained in the raw water are prevented from dissolving in the distilled water, thereby enabling the production of extremely pure distilled water.Type: GrantFiled: June 17, 1988Date of Patent: September 4, 1990Assignee: Hitachi, Ltd.Inventors: Nobuatsu Hayashi, Sankichi Takahashi, Katsuya Ebara, Hideaki Kurokawa, Akira Yamada, Yasuo Koseki, Harumi Matsuzaki, Hiroaki Yoda
