  • Patent number: 11971674
    Abstract: A heating device includes a rotator, a heater, a heater holder, and a first high thermal conduction member. The heater includes a base and a plurality of heat generators being arranged on the base and including neighboring heat generators. The heater has a gap area between the neighboring heat generators. The first high thermal conduction member has a higher thermal conductivity than the base and faces the gap area.

  • Patent number: 11949097
    Abstract: In a nonaqueous electrolyte secondary battery a separator includes a porous substrate, a first filler layer, and a second filler layer. The first filler layer comprises phosphate particles having a BET specific surface area of 5 to 100 m2/g and polyvinylidene fluoride and is formed on a first surface that faces the positive electrode side of the substrate and contacts the positive electrode. The second filler comprises inorganic particles which have a melting point higher than that of the phosphate particles and is formed on at least one of a second surface that faces the negative electrode side of the substrate and the area between the substrate and the first filler layer. The content of the polyvinylidene fluoride in the first filler layer is 10 to 50 mass % and is higher in a region on the positive electrode side than in a region on the substrate side.

  • Patent number: 11942645
    Abstract: A non-aqueous electrolyte secondary battery includes a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode. The separator has a multilayer structure in which a first filler layer containing phosphate particles, a porous resin substrate, and a second filler layer containing inorganic particles having higher heat resistance than the phosphate particles are stacked in this order from the negative electrode side. The first filler layer is disposed on the porous resin substrate in such a manner that the surface of the first filler layer faces the surface of the negative electrode. The phosphate particles have a BET specific surface area in the range of 5 m2/g or more and 100 m2/g or less.

  • Patent number: 11934126
    Abstract: A heating device includes a first rotator, a heater including a base and a heat generator, and a second rotator contacting the first rotator. The heat generator adjacent to the base defines a heat generation area having one edge close to one edge of the base in a longitudinal direction of the base. A length between the one edge of the base and the one edge of the heat generation area is longer than a length between the other edge of the base and the other edge of the heat generation area. The second rotator has one edge close to the one edge of the heat generation area. A length between the one edge of the second rotator and the one edge of the heat generation area is shorter than a length between the other edge of the second rotator and the other edge of the heat generation area.

  • Publication number: 20230332594
    Abstract: A hydraulic pump includes: a valve plate including a suction port and a delivery port; a valve cover to which the valve plate is mounted; and a cylinder block that slides on the valve plate. The valve cover includes a suction passage and a delivery passage. The valve cover includes: a first chamber that communicates with the delivery passage through a communication passage and functions as a Helmholtz resonator; and a second chamber that communicates with the delivery passage, or with the first chamber, through an introduction passage including a restrictor. In the valve cover and the valve plate, a supply passage extends from the second chamber to a bottom dead center-side sealing surface of the valve plate, the bottom dead center-side sealing surface being a surface located between the suction port and the delivery port. The supply passage includes a restrictor.
