  • Publication number: 20220143288
    Abstract: A dialysis apparatus has a connection channel that communicatively connects a dialysate circuit and a blood circuit, and circulates dialysate from the dialysate circuit to the blood circuit via the connection channel during a priming operation. A blood pump has a tube attachment device that switches from an unattached state in which a tube is positioned outside a housing and permits liquid to circulate thereinside, to an attached state in which the tube is in the housing and a rotor compresses the tube. At the time of priming, the liquid feeding pump feeds dialysate from the dialysate circuit to the blood circuit via the connection channel. With the blood pump being in the unattached state, the dialysate is circulated past the blood pump, and then, with the blood pump in the attached state, the dialysate is circulated in a direction opposite to the blood pump.

  • Publication number: 20220115679
    Abstract: A fuel cell system includes a fuel cell, a cathode off-gas discharge channel, a gas-liquid separator, and a cover member. The gas-liquid separator includes a body, a first discharge channel including a first valve seat at an end, and a first valve device including a first valve element and a first driver. The cover member covers at least the first discharge channel and the first valve seat in the gas-liquid separator, and includes a gas channel defining portion that defines a gas channel communicating with the cathode off-gas discharge channel between the cover member and the gas-liquid separator. The gas channel is configured such that a cathode off-gas flowing into the cover member comes into contact with the first discharge channel and the first valve seat and does not come into contact with the first driver.

  • Patent number: 10922632
    Abstract: A client device accepts event information for which a people flow prediction is to be performed from a user and the client device inputs the accepted event information to a people flow prediction device. The people flow prediction device outputs a result of people flow prediction responsive to the input event information to the client device and the client device displays the result of people flow prediction to the user. The people flow prediction device performs a people flow prediction by temporally and spatially allocating an event attendance which has been input from the client device to pathways, each connecting a transport facility at which a people flow originates and an event site. Consequently, it is possible to predict a flow of people who attend an event or the like, the people flow differing from that in an ordinary situation, without need to input real-time data.

  • Patent number: 10895211
    Abstract: A reference range identifying device acquires and records, at a predetermined time interval, a measuring result of a load and exhaust temperature of an engine. The device identifies, based on combinations of the load and exhaust temperature recorded at multiple points of time, for each load zone, for example a 95% confidence interval of a distribution of exhaust temperatures as a reference range. Subsequently, the device calculates an approximate curve for lower limits and upper limits of reference ranges identified for the load zones. The device identifies a range sandwiched by the calculated two approximate curves as a reference range that changes in accordance with a load. The device, upon detecting that a current load and exhaust temperature of the engine is not included in the reference range, notifies the detected fact to a user.

  • Patent number: 10730593
    Abstract: A first unit acquires attribute record data and a second unit acquires deterioration degree data from a terminal device mounted on a ship. The attribute record data indicates an attribute relating to a past sailing of the ship. The deterioration degree data indicates a deterioration degree, which is checked during performance of maintenance work, of each device mounted on the ship. A third unit generates relational data indicating a relation between various attributes relating to the state of the sailing of the ship and the deterioration degree of the device based on the attribute record data and deterioration degree data. A fourth unit acquires estimated attribute data indicating an estimated value of the attributes relating to sailing of the ship. A fifth unit generates timing data indicating a timing of maintenance work to be performed on each device based on the attribute record data, estimated attribute data, and relational data.

  • Patent number: 9592330
    Abstract: A dialysis apparatus has a dialysate circuit 4 which is cleaned after dialysis by both opening/closing valves V101 and V102 being closed after a dialysate in the dialysate circuit 4 is replaced with a cleaning liquid. The opening/closing valve V12 is opened, and the cleaning liquid is circulated by pumps P1 and P4 while being heated by a heater H1, to clean the inside of the dialysate circuit 4. A deaeration tank 31 is provided downstream of the pump P1. Air bubbles generated from the cleaning liquid serving as hot water are deaerated by the deaeration tank 31 and are then discharged into a gas storage tank 48 via a deaeration passage 32. The pumps P1 and P4 can be reliably prevented from being unable to operate with the air bubbles generated from the cleaning liquid.
