  • Patent number: 11971202
    Abstract: In an air-conditioning apparatus, an outdoor unit installed in an outdoor space and an indoor unit installed in an indoor space are connected by refrigerant pipes to form a refrigerant circuit. One or more pairs of valve kits are provided at the refrigerant pipes by which the outdoor unit and the indoor unit are connected, and allow a pair of additional refrigerant pipes on an inflow side and an outflow side to be connected to one of the one or more pairs of valve kits, the pair of additional refrigerant pipes being additionally provided to enable a new indoor unit to be added after installation of the air-conditioning apparatus. The valve kits of the one or more pairs of valve kits have respective distal end portions that are inclined upwards relative to a horizontal direction. The distal end portions each allow an associated one of the additional refrigerant pipe to be connected to the distal end portion.

  • Patent number: 11000980
    Abstract: Disclosed is a textile-like in-mold sheet that is to be integrated with a resin molded body molded by injection of a molten resin by in-molding. The textile-like in-mold sheet includes at least a fiber sheet layer, a first adhesive layer, and a textile material layer, in this order from a surface that will serve as a side to be integrated with the resin molded body. Alternatively, the textile-like in-mold sheet includes at least a textile material layer and a temporary surface protection layer temporarily bonded to the textile material layer, in this order from the surface to be integrated with the resin molded body.

    Abstract: Disclosed herein is a textile-like in-mold sheet that is to be integrated with a resin molded body molded by injection of a molten resin by in-molding. The textile-like in-mold sheet includes a first surface that is to be integrated with the resin molded body, and a second surface that will serve as a back side of the first surface, such that the textile-like in-mold sheet contains at least a textile material layer and a temporary surface protection layer temporarily bonded to the textile material layer, in this order from the first surface toward the second surface.

  • Patent number: 9985530
    Abstract: A soft switching system DC-DC converter includes a switching element, a transformer or a reactor, and a controller configured to control a switching operation of the switching element; and carries out the switching operation of the switching element in a state that a voltage or a current to be applied to the switching element is zero. In a case where a required output value of the DC-DC converter is lower than the minimum output over which soft switching is established, the controller controls the operation of the switching element so that an operation period in which an output of the DC-DC converter becomes the minimum output or higher and a stop period in which the output becomes zero are alternately repeated.
