Abstract: Provided is a clean booth in an assembled state, including: a frame; a wall portion that is provided on the frame and forms an internal space; a first unit that is provided on the wall portion and includes a first fan that supplies air to the internal space via a first filter; and a second unit that is provided on the wall portion and includes a second fan that exhausts the air in the internal space.

Abstract: Provided is a drive mechanism capable of withstanding sterilization treatment using a sterilization gas such as hydrogen peroxide and capable of performing positioning operation with heightened accuracy. In a drive mechanism according to the invention, a movable block disposed in the internal space of a partition wall for blocking a sterilization gas is coupled to a movable platform disposed in the external space of the partition wall by means of a magnet coupling mechanism. Further, biasing magnet units are disposed on surfaces, of the movable block and the movable platform, on which no magnet coupling mechanism is disposed, such that the biasing magnet units serve as magnetic poles repelling each other. Repelling force generated by the biasing magnet units serves as biasing force that biases the movable platform toward the partition wall.

Abstract: A switching valve includes a rotor having a pair of rollers rotatably mounted on both ends thereof, a rotor drive unit rotationally driving the rotor, a pair of pressing members, each being provided at a position where each of the pair of pressing members cooperates with each of the pair of rollers outside a revolution orbit of each of the pair of rollers revolving by rotation of the rotor, and a pair of tubes, each being disposed between the revolution orbit of each of the pair of rollers and each of the pair of pressing members. A rotation center axis of the rotor is disposed on a straight line connecting centers of rotation of the pair of rollers, and each pressing member has the pair of pressing areas symmetrical with respect to a straight line passing through the center of rotation of the rotor and extending a vertical direction.

Abstract: Since a drive unit is disposed in a body of a switching valve included in a suction-discharge device in the related art and a sample flows in the body of the switching valve, a treatment, such as autoclave sterilization, could not be performed. For this reason, a contamination cause, such as bacteria, could not be completely removed. Since a switching valve of the invention is formed of a mechanism for blocking tubes by pressing the tubes, in which a sample flows, from the outside, a contamination cause, such as bacteria, is not spread to the switching valve. Further, tubes and a syringe pump, which are installed on a suction-discharge device of the invention, form an assembly that can be easily replaced even though contamination is generated.

Abstract: A processing system for cell cultures for carrying out cell/tissue culturing processes in the field of regenerative medicine, etc. which is a processing system for cell cultures which prevents viruses and human-derived cells, etc. other than a culturing processing target from entering the interior of a closed space from outside of the system to maintain sterility, maintains sealability of the closed spaces of modules, and couples or detaches the plurality of modules in accordance with a wide variety of cell culturing processing steps so that cell culturing processes can be carried out by combining the plurality of culturing processing modules is provided.

Abstract: A shuttle-type conveying system to convey an article. The system includes a feeding and collecting device capable of setting a cassette in which articles to be conveyed are stacked as they are on a rotating and feeding table, a pickup device taking out the article and placing it on a receiving/delivery table, and a conveying device feeding the article on the receiving/delivery table to another receiving/delivery table by a shuttle conveying portion traveling on conveying paths below the receiving/delivery table. After the article is lifted up by the shuttle conveying portion and moved to outside the receiving/delivery table, the article is lowered below the receiving/delivery table and made to travel under the receiving/delivery table to another receiving/delivery table.
