Abstract: A water electrolysis system includes a control device. The control device outputs a first current command value, which is a constant current command value, to one from among a first power source device and a second power source device. The control device generates a second current command value, which is an undefined current command value, based on an amount of the hydrogen gas inside a gas-liquid separator, and outputs the second current command value to another one from among the first power source device and the second power source device.

Abstract: A regenerative fuel cell system includes a supply mechanism for supplying gas generated by a pressurization apparatus to a fuel cell, and a control apparatus. The supply mechanism includes a flow regulating valve provided in a gas supply path, and a pressure sensor that detects pressure of the gas supplied to the gas supply path. When a pressurization-stop operation is started, the control apparatus adjusts the flow rate of the flow regulating valve to realize a target depressurization rate, and causes the fuel cell to generate power corresponding to the flow rate.

Abstract: The apparatus for manufacturing bags for medical use includes an extruding machine, a device for forming an extruded tube, a device for supplying outlet devices, and a device for conveying the extruded tube horizontally. The device for forming the extruded tube has a die through which pass a sterile air supply line, a medical fluid supply line, an air recovering line and a second sterile air supply line which passes through the medical fluid supply line. The extruding machine extrudes a tube in a fused state and outlet devices are welded to the extruded tube in the fused state. The extruded tube is pressed by the formation device at intervals along it to form fused portions bounding chambers and a fluid passage through each fused portion to connect the chambers. Sterile air is fed into the extruded tube and the shape of the extruded tube is maintained by the pressure of the sterile air.

Abstract: A method of manufacturing a medical hollow fiber device for removing waste material in the blood, including the steps of providing a housing; coiling hollow fiber membranes into loops; providing bundles of the loops whose entire interior is filled with a liquid and placing them into the housing; closing both ends of the housing with caps; supplying viscous potting material into the housing at the end portions of the hollow fiber membranes, and applying a centrifugal force to the housing. The potting material penetrates between the end portions and exerts an outside pressure on the membranes. The liquid in the membranes moves toward both ends of the housing and exerts an inside pressure overcoming the outside pressure of the potting material until the potting material solidifies.
