  • Patent number: 11124003
    Abstract: An article includes a body member and a detachable member detachably attached to the body member. One of the body member and the detachable member includes a cover portion having an engaging portion on an inner wall face of the cover portion. The other includes a covered portion that is covered with the cover portion and has an engaged portion on an outer wall face of the covered portion. The engaging portion and the engaged portion are configured to be disengaged by warping the cover portion so that the cover portion displaces to an outer wall face side of the cover portion. The one of the body member and the detachable member includes a finger-applying-position indicator at a position deviated from a portion corresponding to the cover portion, on an outer wall face of the one. The finger-applying-position indicator indicates a position to be applied with fingers of a user.

  • Patent number: 11124044
    Abstract: An air conditioner includes a circulation flow channel in which a refrigerant circulates, an evaporator provided in the circulation flow channel to cool air by heat exchange with the refrigerant passing through the circulation flow channel, a first cold storage unit provided in the evaporator at a position adjacent to a tube in which the refrigerant flows in the evaporator, and a second cold storage unit provided in the circulation flow channel at a position different from the evaporator. The first cold storage unit is configured to store therein a first cold storage material which changes in phase by the heat exchange with the refrigerant passing through the tube, and the second cold storage unit is configured to store therein a second cold storage material which changes in phase by the heat exchange with the refrigerant passing through the circulation flow channel.

  • Patent number: 11078909
    Abstract: A scroll compressor includes a fixed scroll and an orbiting scroll. An orbiting angle of the orbiting scroll when a compression chamber is formed and compression of fluid is initiated is referred to as an orbiting initiation angle. An orbiting angle of the orbiting scroll when the compression of the fluid is terminated is referred to as an orbiting termination angle. An orbiting angle of the orbiting scroll when an end of the orbiting spiral wall initiates contact with an arcuate portion of the fixed spiral wall is referred to as a distal end contact initiation angle. The formation point distance is a peak in at least one of orbiting angles obtained by subtracting integer multiples of 360° from an orbiting angle in a range from the distal end contact initiation angle to the orbiting termination angle.
