  • Patent number: 8652834
    Abstract: A culturing apparatus has a culture vessel having a first elastic seal bonded on its upper surface and a culture space formed thereon, and a joint for supplying solution such as a medium to the culture vessel and a second elastic seal having microprojection formed at the lower face. The first elastic seal has a valve for supplying or discharging solution. The second elastic seal is formed with microprojection at the position corresponding to a valve for preventing a spill. The culture vessel and the joint are sucked between the first elastic seal and the second elastic seal, thereby forming an integral seeding device.

  • Patent number: 8518693
    Abstract: A temperature regulating member for avoiding a deterioration in heat radiating output efficiency and deterioration in buffering occurring due to a non-uniform heat distribution within the heat storage material. Heat non-uniformities within the heat storage material are eliminated by inserting one or multiple agitating tools inside the heat storage material by generating an agitating current occurring due to use of agitator tools whose relative positions change within the heat storage material during shipping.

  • Patent number: 8216831
    Abstract: A cell culture device comprises a fluid mechanism for branching a liquid appropriately in its flow passage when the liquid is injected to a plurality of culture vessels in a set and feeding equal amounts of the culture broth to the culture vessels at the same time. The device, in one form, has one or plural recess portions so that one or plural culture vessels can be contained in alignment, in view of space efficiency, m x n (row x column) pieces of culture vessels can be set in a matrix type. By using a pump, the culture broth is branched by a multi-way valve for distributing the liquid in an appropriate amount from a tank containing the culture broth, and the liquid is fed at the same time to the plurality of culture vessels in the culture vessel set.

  • Patent number: 8163541
    Abstract: A cell culture apparatus is provided in which a plurality of culture vessels can be mounted and removed in a set, which has a regulation mechanism that can fix each culture vessel in the correct position, and which enables suppression of production costs. The cell culture apparatus has one or a plurality of concave portions, and can arrange and accommodate one or a plurality of culture vessels in the concave portions. Spring-type fixing devices are provided in the depth direction and the width direction, respectively, in each concave portion. The two spring-type fixing devices press against side surfaces of the culture vessel to fix the culture vessel in the culture vessel set. At this time, by pressing against the culture vessel at two points, the position of the culture vessel at the time of fixing can be maintained with good accuracy.

  • Patent number: 8042604
    Abstract: A temperature regulating member capable of avoiding deterioration in heat dissipation efficiency of a heat-accumulating material, and deterioration in a buffer function thereof, due to ununiformity in heat distribution inside the heat-accumulating material. With the use of a churning flow occurring by disposing one piece of stirrer or plural stirrers inside the heat-accumulating material, and by causing a relative position of the stirrer, inside the heat-accumulating material, to be changed during transportation, it is possible to eliminate ununiformity in heat distribution inside the heat-accumulating material. The temperature regulating member has a feature in that a phenomenon of a peripheral part of the heat-accumulating material being first cooled to be subsequently solidified is avoided, thereby enabling the heat dissipation efficiency and the buffer function to be maintained.
