  • Patent number: 10845098
    Abstract: An air conditioner is provided, which is capable of accurately determining appropriateness of a refrigerant amount in a refrigerating cycle. A control apparatus is configured to: stop a cooling operation; set an expansion valve to a fully-closed state and, at the same time, switch the selector valve to change the direction, in which a refrigerant flows, to an opposite direction; operate a compressor to perform a refrigerant recovery operation, in which a refrigerant contained in an outdoor heat exchanger is recovered by an indoor heat exchanger; and determine the appropriateness of a refrigerant amount in a refrigerating cycle, based on at least one of a time required for recovering the refrigerant, a pressure change in a refrigerant suctioned by the compressor, and temperature of the refrigerant discharged from the compressor during the refrigerant recovery operation.

  • Publication number: 20200290153
    Abstract: Firstly, an upper base material is disposed above a lower base material. Secondly, a laser beam is irradiated so that an area irradiated with a laser beam at a time of melting start is formed on only an upper surface of the upper base material or on only both the upper surface and an end surface of the upper base material, whereby the end surface of the upper base material and the lower base material are fillet welded. With the end surface as a reference, a side the upper surface and the lower surface are positioned is a first side, and an opposite side of the first side is a second side. The laser beam is set such that an intensity of the laser beam is lower toward the second side from the first peak area within the irradiation area of the laser beam.

  • Patent number: 10466646
    Abstract: A photosensitive drum is rotatable about a first axis extending in a particular direction. A frame rotatably supports the photosensitive drum. A developing roller is rotatable according to driving force about a second axis extending in the particular direction. A surface of the developing roller contacts a surface of the photosensitive drum through toner. A resistance generating member generates a resistance torque TQ1 serving as resistance between the frame and photosensitive drum in a case where the photosensitive drum rotates relative to the frame. In a case where the developing roller rotates according to the driving force in a state where the surface of the developing roller contacts the surface of the photosensitive drum through toner, the resistance torque TQ1 is smaller than a torque TQ2 that causes the photosensitive drum to rotate due to friction between the surface of the developing roller and the surface of the photosensitive drum.
