Patent number: 4339537Abstract: Biological substances such as tissues, cells, vaccines and viruses are cultured by the steps of: introducing a culture solution having the substances suspended therein into a closed culture vessel having a plurality of disc-like implantation plates arranged horizontally with a certain space between successive plates so that a predetermined number of the implantation plates is immersed in the culture solution; culturing the substances on the surface of the implantation plates; removing the substances from the implantation plates; suspending the removed cultured substances in a new culture solution; and successively repeating the steps of culturing, removing the cultured substances and suspending in a new culture solution while each time increasing the amount of newly supplied culture solution to progressively increase the number of implantation plates immersed in the culture solution.Type: GrantFiled: November 6, 1979Date of Patent: July 13, 1982Assignee: Olympus Optical Company LimitedInventors: Shinroku Sogi, Masao Izawa, Shinichiro Hattori, Ikuo Tawara, Daizo Shinohara, Sachiko Tachikawa

Patent number: 4234023Abstract: A liquid feeder comprises a liquid suction and delivery pump which withdraws a liquid such as a culture solution, buffer solution, enzyme solution or the like which is retained in a liquid storage container as refrigerated or at a reduced temperature and delivers it through a flexible tube for injection into a culture vessel located within an incubator. The tube is inserted into an inner pipe and is sealingly secured thereto. The inner pipe is detachably and hermetically mounted in an outer pipe which extends through and is secured to a wall forming an environment isolating layer of the incubator. An eccentric crankpin which is driven by a motor is connected through a link with another crankpin having a greater eccentricity, the latter crankpin being driven for rotation to cause a reciprocatory rotating motion of a driven shaft about its own axis through an angular extent of less than 180.degree..Type: GrantFiled: December 26, 1978Date of Patent: November 18, 1980Assignee: Olympus Optical Co., Ltd.Inventors: Shinroku Sogi, Makoto Yoshinaga, Toshio Shinohara, Takayuki Aihara, Ikuo Tawara

Patent number: 4210724Abstract: An apparatus for liquid disposal and distribution in automatic culture system comprises a first turntable carrying a plurality of culture vessels disposed in an array on a common circle thereon, and a second turntable carrying a plurality of centrifuge tubes disposed in an array on a common circle thereof. The apparatus comprises a pipette holding arm which is disposed so that its free end is angularly movable between one of the culture vessels and one of the centrifuge tubes. The free end of the arm has attached thereto a tapered cylinder which detachably receives a pipette. A fixed displacement pump is connected with the cylinder, which is movable along the path of rotation, along which are disposed a pipette holder, a pipette remover and a liquid disposal pot. The apparatus also comprises a rotary and elevating mechanism associated with the arm.Type: GrantFiled: March 20, 1978Date of Patent: July 1, 1980Assignee: Olympus Optical Co., Ltd.Inventors: Shinroku Sogi, Makoto Yoshinaga, Toshio Shinohara, Takayuki Aihara, Ikuo Tawara
