Abstract: A water quality measuring device comprises a measurement cell (10), a sample water supply unit (80), a reagent supply unit (30), an agitating unit (17), a measuring unit (20) and a control unit (90). The sample water supply unit (80) includes an inlet channel (12) configured to supply the measurement cell (10) with sample water and an outlet channel (13) configured to discharge sample water from the measurement cell (10). The inlet channel (12) is connected to a flow channel (2) configured to supply sample water, and includes a filter (13) and an electromagnetic valve (15). The control unit (90) opens the electromagnetic valve (15) for supplying sample water to allow sample water, from which foreign substances are removed by the filter (13), to flow into the measurement cell (10).

Abstract: A medicine package includes a container for containing a fluid medicine, a tube body for connecting an interior and an exterior of the container, a tube made of an elastic material, and a nozzle for discharging the medicine. The container is made of soft sheets each configured by laminating resin film layers and an aluminum foil layer, and provided as a bag having a gusset on either side. An inclined section is provided at an adhered section between the sheets such that an internal space of the container forms a funnel shape with the tube body as a stem.

Abstract: A time zone when the operation pattern is obtained with a high learning convergence and a time zone when such an operation pattern cannot be obtained are set in advance. In the case where a significant difference develops between a target operation pattern and an actual load pattern, it is possible to accurately determine whether the operation is to be continued without changing the operation pattern or the operating conditions such as the hydrogen production amount should be changed in accordance with the actual load pattern. As a result, based on the scheduled operation with a predetermined operation pattern, the operation can be easily corrected in accordance with the complicated load change in home applications.

Abstract: A fuel-cell power system includes a fuel cell stacks, a power conversion unit for controlling and receiving the current from the fuel-cell stacks, a hydrogen production unit for supplying hydrogen to the fuel-cell stacks, and an operation unit for carrying out the operation with a simulated load connected for selected one of an arbitrary time and a predetermined time before the service operation of the fuel-cell power system, thereby the hydrogen production unit having the combustor for refluxing and combusting an anode off-gas is started in stable fashion at the same time as the system.
