  • Patent number: 11839052
    Abstract: An apparatus includes a conduit configured to circulate magnetic fluid, and a magnetic field generator that applies a magnetic field to the magnetic fluid. The conduit includes at least four areas of a first conduit area in which the magnetic fluid receives heat from a heating unit, a second conduit area from the first conduit area to a cooling unit, a third conduit area in which the magnetic fluid is cooled by the cooling unit, and a fourth conduit area from the cooling unit to the heating unit. When the apparatus is used, a volume of the magnetic fluid in one of the first to fourth conduit areas, in which a flow direction of the magnetic fluid coincides with a gravity direction, is larger than that of another conduit area, in which the flow direction of the magnetic fluid does not coincide with the gravity direction.

  • Patent number: 11819570
    Abstract: A sugar-responsive gel that is highly resistant to temperature changes, and a sugar-responsive drug delivery device including such a gel. The sugar-responsive gel, which comprises a gel composition including a monomer having a hydroxyl group in addition to a phenylboronic-acid-based monomer, can exhibit suitable temperature resistance. A sugar-responsive drug delivery device including such a sugar-responsive gel is less susceptible to the effects of temperature changes, and therefore can prevent undesirable excessive delivery of a drug such as insulin.

  • Patent number: 11813999
    Abstract: An occupant protection device is such that an airbag is housed in a housing region of a lap belt portion that can be disposed on a front side of a waist portion of an occupant seated in a seat. The airbag can receive and protect an upper body of the occupant using a rear face side occupant restraining face when inflation is completed. The airbag includes an exhaust port that can discharge an inflating gas and a regulating valve mechanism that restricts a discharge of the inflating gas from the exhaust port. The regulating valve mechanism permits a discharge of the inflating gas from the exhaust port when a protrusion upward of the airbag from the housing portion is restricted, and restricts a discharge of the inflating gas from the exhaust port when a protrusion upward of the airbag from the housing portion is not restricted.

  • Publication number: 20230361312
    Abstract: Provided is a bipolar storage battery in which an electrolytic solution is less likely to enter the interface between a positive electrode and an adhesive layer. Thus, battery performance is less likely to be reduced even if growth occurs in the positive electrode due to corrosion by sulfuric acid contained in the electrolytic solution. The bipolar storage battery includes a bipolar plate including a support column configured to support adjacent plates to each other when stacked, a positive current collector bonded to one surface of the bipolar plate by an adhesive, a positive active material layer placed on the positive current collector, a negative current collector bonded to another surface of the bipolar plate by an adhesive, a negative active material layer placed on the negative current collector, and a cover plate covering a peripheral edge portion of the positive current collector.
