  • Publication number: 20170263951
    Abstract: There is provided a frame body used for a cell of a redox flow battery, that can improve heat dissipation of an electrolyte in a slit while reducing a shunt current loss through the electrolyte, and can also suppress strain caused at a slit formation portion. It is a frame body used for a cell of a redox flow battery, comprising: an opening formed inside the frame body; a manifold allowing an electrolyte to pass therethrough; and a slit which connects the manifold and the opening and forms a channel of the electrolyte between the manifold and the opening, the slit having at least one bent portion, the at least one bent portion having a radius of curvature of 2.0 mm or more and 200 mm or less.

  • Publication number: 20170213928
    Abstract: This power generation circuit unit includes a wiring substrate and a plurality of power generating elements mounted to the wiring substrate. The wiring substrate includes: a first substrate (32E) and a second substrate (32F) to each of which the power generating element is mounted; and a coupling portion (33L) configured to couple the first substrate (32E) and the second substrate (32F) together. The first substrate (32E) can be disposed at at least two positions of: a first position separated from the second substrate (32F) by a first distance; and a second position separated from the second substrate (32F) by a second distance being greater than the first distance. The coupling portion (33L) has an FPC (flexible printed circuits). In a state where the first substrate is disposed at the second position, at least a part of the coupling portion (33L) is twisted.

  • Publication number: 20170054161
    Abstract: There is provided a frame body used for a cell of a redox flow battery, that can improve heat dissipation of an electrolyte in a slit and can suppress rise of the temperature of the electrolyte. It is a frame body used for a cell of a redox flow battery, comprising: an opening formed inside the frame body; a manifold allowing an electrolyte to pass therethrough; and a slit which connects the manifold and the opening and forms a channel of the electrolyte between the manifold and the opening, the slit having a pair of sidewalls facing each other in a cross section orthogonal to a direction in which the electrolyte flows, the slit having, at at least a portion thereof in the slit's depthwise direction, a width narrowing portion allowing the sidewalls to have a spacing narrowed in the depthwise direction.

  • Patent number: 9553711
    Abstract: A counting unit of a base station counts the number of terminals located in an area covered by the base station for each of communication carriers corresponding to the terminals. An assigning unit assigns each of cells in a first group to any of the communication carriers, where each of the cells is a frequency band of the base station 10 and occupied by one terminal communicating with the cell.
