  • Publication number: 20240071223
    Abstract: A travelling control system includes a plurality of vehicles each including a controller, a server including a generator configured to generate a travelling control information for the plurality of vehicles, a predictor configured to predict a merging interference between a first vehicle travelling from a merging road toward a main road and a second vehicle travelling on the main road, a sender which is provided in the first vehicle to send an interference suppressing request, and a receiver which is provided in the second vehicle to receive the interference suppressing request. The controller of the second vehicle travelling on the main road is configured to execute interference suppressing control of suppressing an approach of the second vehicle to the first vehicle travelling from the merging road to the main road, in a case that the receiver receives the interference suppressing request from the first vehicle.

  • Patent number: 10108363
    Abstract: A storage system comprises multiple storage apparatuses and the multiple storage apparatuses provide a host system with a virtual volume in which multiple logical volumes are virtualized into one. When a first storage apparatus has detected a first event, the first storage apparatus changes the status of a first resource. Thereafter, the first storage apparatus sends a notice of the status change with respect to a first logical volume to a second storage apparatus comprising a second logical volume which is the basis of a virtual volume associated with the first logical volume, when the first storage apparatus has detected a second event which signifies that the host system is informed, in the future, of the status of the first resource. The second storage apparatus receives the notice and configures the status change based on the received notice.

  • Patent number: 10011812
    Abstract: This invention provides a culture control method and a cell culture apparatus that enable stable cell culture by regulating shear stress to be applied to cells within an adequate range. With the application of such culture control method and cell culture apparatus, cell culture is performed under agitation culture conditions in which the shear stress distribution is 0.5 Pa to 20 Pa in 80% or more of the culture vessel by volume.

  • Publication number: 20150192568
    Abstract: A method for easily and non-invasively determining a degree of stratification and/or differentiation of cultured cells, and an apparatus for determining a degree of stratification and/or differentiation of cultured cells are provided. The invention relates to a method for determining a degree of stratification and/or differentiation of cultured cells, including: (a) a harvesting step of harvesting a culture solution of the cultured cells; (b) an analytical step of analyzing at least one type of a metabolite of the pentose phosphate pathway and/or the TCA cycle in the culture solution; and (c) a determination step of referring to a database of correlations between prospectively-obtained degrees of stratification and/or differentiation of the cultured cells and analytical results of metabolites, for analytical results obtained in the analytical step, to determine the degree of stratification and/or differentiation of the cultured cells.

  • Publication number: 20100081122
    Abstract: A state of cells while being cultivated is ascertained and a feed medium suitable for the cell state is added for producing a target substance to be produced with a high yield. The system for cultivating cells of the invention includes a bioreactor/fermentor for cultivating cells to be cultivated, a measuring device for measuring the culture cells being cultivated in the bioreactor/fermentor or a component contained in the culture solution, and a control device for selecting a feed medium to be added to the bioreactor/fermentor from two or more feed media having different composition ratios based on the culture cells state determined by measured values obtained by the measuring device.

  • Publication number: 20090148946
    Abstract: A cell is separated from a culture broth with an extremely simple configuration, and production yield of a target product is improved. There are provided separating means for separating a cell from the culture broth containing the cell, a buffer tank connected to the separating means through a first pipeline, at least one or more liquid reservoir tank connected to the buffer tank through a second pipeline, a first valve disposed on the first pipeline and controlling communication between the separating means and the buffer tank, and a second valve disposed on the second pipeline and controlling communication between the buffer tank and the liquid reservoir tank.
