  • Patent number: 11577737
    Abstract: A heat management device for a vehicle equipped with heat related systems includes an acquisition unit and a flow rate control unit. The acquisition unit is configured to acquire a temperature related value from electronic control devices corresponding to the heat related systems. The temperature related value includes a temperature adjustment related value and/or an upper limit value. The flow rate control unit is configured to control switching devices that switch flow rate of fluid flowing through the heat related systems from a common path in which the fluid can circulate between the heat related systems. The flow rate control unit controls flow rate of the fluid flowing from the common path to the heat related systems by controlling the switching devices in response to the temperature related value acquired by the acquisition unit for a predetermined scene of the vehicle.

  • Patent number: 9039789
    Abstract: The whole of a conductive material layer is formed on a bonding surface of an outer film having flexibility and barrier properties to prepare a composite body in which the conductive material layer is integrated with the outer film. A current collector is located within an application region, and at least a part of an electrode terminal is located outside the application region. A positive electrode active material precursor layer, an electrolyte precursor layer, and a negative electrode active material precursor layer are added to the composite body with plane positions thereof aligned with that of the current collector. These precursor layers are subjected to a crosslinking process. The application regions are applied, and the outer films are bonded, to seal a cell. The crosslinking process may be omitted.

  • Publication number: 20120315547
    Abstract: This invention relates to a matrix of a solid electrolyte having a microstructure in which a non-reactive polyalkylene glycol is held on a co-crosslinked product produced by chemically co-crosslinking a hyperbranched polymer with a crosslinkable ethylene oxide multicomponent copolymer, such that a lithium salt is dissolved in the matrix. A negative electrode active material layer is a layer obtained by dispersing a negative electrode active material and a conduction aid in a lithium-ion conducting solid electrolyte. A positive electrode active material layer is a layer obtained by dispersing a positive electrode active material and a conduction aid in a lithium-ion conducting solid electrolyte.

  • Patent number: 8101701
    Abstract: Fumaric acid derivatives and ophthalmic lenses using them are disclosed. More specifically, a fumaric acid derivative having a hydrophilic group and a silicon-containing alkyl group within a molecule, and contact lenses or intraocular lenses using the same are disclosed. The fumaric acid derivatives of the present invention provide, on one hand, superior oxygen permeability by having a silicon-containing alkyl group within the molecular structure, and on the other hand, improved compatibility with other hydrophilic monomers by having a hydrophilic group within the same molecule. When ophthalmic lenses obtained by polymerizing monomer compositions containing the fumaric acid derivative are constructed as, for example, water content lenses, lenses with high oxygen permeability independent from the water content may be obtained, wherein the fumaric acid derivatives is superior in compatibility with the hydrophilic monomer used in combination and allows the combination in various mixing ratios.
