Abstract: A management system includes a plurality of resources configured to be electrically connected to an external power supply, and a management device configured to manage the resources. The management device includes a planning unit and a management unit. The planning unit is configured to determine a power balancing plan of each of the resources by using first information on a use schedule of each of the resources and second information indicating a magnitude of an environmental load in a process of generating electric power to be supplied by the external power supply. The management unit is configured to manage the resources to cause each of the resources to operate according to the power balancing plan or a modified power balancing plan in power balancing of the external power supply.

Abstract: An air conditioner includes a housing having a first outlet and a second outlet, a first channel communicating with the first outlet, a second channel communicating with the second outlet, a sensible heat exchanger to exchange sensible heat between a first air flowing through the first channel and a second air flowing through the second channel, a first vaporization filter to cool the first air by latent heat of water and a second vaporization filter to cool the second air by latent heat of water. The first vaporization filter is disposed downstream of the sensible heat exchanger in a flow direction of the first air. The second vaporization filter is disposed upstream of the sensible heat exchanger in a flow direction of the second air.

Abstract: To provide a fuel tank check valve making it easy to assemble a cap to a valve element housing. This fuel tank check valve has a body tube provided with a valve element housing, a valve element, a cap, and a spring, wherein the valve element housing has a base end side frame, a tip end side frame to which the cap is mounted, and a first coupling frame connecting the both frames, the tip end side frame is provided with a retraction portion having a shape in which a circumferential part is retracted from the tip end surface thereof to the base end side frame side, the cap is formed with a notch whose circumferential part is notched, and the cap is assembled to the valve element housing so that the notch is positioned in the retraction portion.

Abstract: A rotor of a rotary electric machine includes: a rotor core; a plurality of magnets arranged on an outer peripheral surface of the rotor core; and a rotor shaft rotating integrally with the rotor core. The rotor shaft includes an in-shaft flow path through which a refrigerant is supplied. The rotor core includes: an in-core flow path extending inside the rotor core in an axial direction of the rotor core; a first refrigerant flow path extending from the in-shaft flow path through the in-core flow path and further in a radial direction of the rotor core; a second refrigerant flow path connected to the first refrigerant flow path and extending in a circumferential direction of the rotor core; and a third refrigerant flow path connected to the second refrigerant flow path and extending in the axial direction along the plurality of magnets.

Abstract: A rotor of a rotary electric machine includes: a rotor core; a plurality of magnets; and a rotor shaft. The rotor core includes: a plurality of magnet attaching grooves formed on the outer peripheral surface of the rotor core and in which the magnets are disposed; an in-core flow path extending inside the rotor core in an axial direction of the rotor core; and a refrigerant distribution plate. The refrigerant distribution plate includes: a first refrigerant distribution plate in which an inner-diameter-side refrigerant flow path extending from an in-shaft flow path toward the in-core flow path as viewed from the axial direction is formed; and a second refrigerant distribution plate in which an outer-diameter-side refrigerant flow path extending from the in-core flow path toward the magnet attaching groove as viewed from the axial direction is formed. The first refrigerant distribution plate and the second refrigerant distribution plate are stacked in the axial direction.
