Abstract: A culture device supplying an accurate amount of liquid into a culture bag has a culture bag having ports, a first bag holding portion having supporting surfaces supporting the culture bag, a rotation mechanism rotating the first bag holding portion, a liquid supplying mechanism supplying a liquid through a tube communicating with the ports a weight detector detecting the weight of the culture bag and the first bag holding portion, and a control portion, in which the control portion sets a first reference value according to a first detection information output from the weight detector in a first state and carries out a liquid supplying step of stopping the liquid supplying mechanism under the condition where a second detection information output from the weight detector when a liquid is supplied to the culturing bag reaches a first target value obtained by adding the weight of the liquid to be supplied to the first reference value.

Abstract: According to one embodiment, a processing device comprises a substance arrangement part, a generating source arrangement part, and a collimator. A substance is arranged on the substance arrangement part. The generating source arrangement part is arranged at a position separated away from the substance arrangement part. A particle generating source that is able to emit a particle to the substance is arranged on the generating source arrangement part. The collimator is configured to be arranged between the substance arrangement part and the generating source arrangement part. The collimator includes: a frame; and a first rectifying part that includes a plurality of first walls and a plurality of first through holes formed with the first walls and extending in a first direction from the generating source arrangement part toward the substance arrangement part, the collimator configured to be removably attached to the frame.

Abstract: A culture system has a culture bag for suspending and culturing pluripotent stem cells in a culture medium; a waste liquid container for storing used culture medium that is connected to the culture bag; a fresh medium container for storing a fresh culture medium that is connected to the culture bag; three-way stopcocks for switching flow channels from the culture bag to the waste liquid container or the fresh culture medium container, etc.; a trap portion for trapping the pluripotent stem cells in the culture medium in the flow toward the waste liquid container side; and a filter portion for subculturing that is formed in fourth and fifth flow channels in parallel to a first flow channel. The first flow channel connects the trap part to the culture bag, and has a mesh by which a cell mass of the pluripotent stem cells can be divided. A pump is used to pump the liquid in the individual flow channels.

Abstract: According to one embodiment, a semiconductor manufacturing apparatus comprises an electrostatic chuck and a control unit. The electrostatic chuck includes an electrode. The electrode generates electrostatic force. A work is mounted onto the electrostatic chuck. The work is attracted and stuck to the electrostatic chuck by the electrostatic force. The control unit controls a voltage supplied to the electrode. The control unit adjusts the voltage according to change in attractive force on the work to the electrostatic chuck associated with mounting works onto the electrostatic chuck and processing the works.

Abstract: A cultured skin and a grafting cultured skin sheet are provided, each of which is a cultured reconstructive skin with a high take rate using cells collectable from cells originated from tissue included in an umbilical cord such as tissue included in an umbilical cord originated from a human fetus. The grafting cultured skin stratified sheet is prepared by placing an epithelium sheet on the top surface of a cultured dermis. The cultured dermis includes as components a cultured skin containing cells originated from a tissue included in an umbilical cord, such as umbilical cells, more concretely, umbilical fibroblast cells, being separated and cultured, preferably in a collagen nonwoven fabric. On the other hand, the epithelium sheet is prepared by culturing and stratifying the umbilical cord epithelium cells.
