A device for measuring a tension of a cell structure containing muscle cells includes a first and a second gel adaptor holder. The first gel adaptor holder includes a frame member and a first gel holding portion which is disposed protrudingly from a part of an inner surface of the frame member for fixing one end of a gel. The second gel adaptor holder includes a second gel holding portion that fixes another end of the gel, and connecting members connected with the second gel holding portion. A kit including the device, a substrate and a gel forming cover. The substrate includes a pair of gel shaping convex parts fitted along the inner surface of the frame member. The gel forming cover includes a surface parallel to a gel contacting surface of the substrate, in order to form an upper surface of the gel.

An object of the present invention is to obtain a thicker animal cell composition by a simple and less expensive method. Namely, an object of the present invention is to provide a method for culturing a thicker animal cell composition by eliminating the hypoxia associated with animal cell compositions, a method for producing an animal cell composition containing unicellular algae, and an animal cell composition. The present invention provides a method for culturing an animal cell composition in a culture medium in the presence of unicellular algae and under exposure to light. According to the method of the present invention, oxygen can be continuously supplied in the culture medium, cell damage is alleviated, and a thicker cell composition can be obtained in the absence of a capillary network.

According to one embodiment, a storage battery control device includes a first reception unit, a second reception unit, a calculation unit, a generation unit, and a transmission unit. The first reception unit receives a charge and discharge command from a power management device. The second reception unit receives a current electricity storage state from each of storage batteries. The calculation unit calculates a control amount, which indicates a ratio of the current electricity storage state in an operation range, with respect to each of the storage batteries on the basis of the current electricity storage state and the operation range of the electricity storage state. The generation unit generates a charge and discharge output value, which is an output value of charge and discharge for the each of the storage batteries, on the basis of the control amount and the charge and discharge command, the control amount calculated for each of the storage batteries, the charge and discharge command received by the first reception unit. The transmission unit transmits the charge and discharge output value to each of the storage batteries, the charge and discharge output value generated by the generation unit.
