  • Patent number: 10411312
    Abstract: A first fin is formed on a first inside wall surface to protrude therefrom. The first fin exchanges heat between fluid and the first inside wall surface. A first fluid passage is divided between a first region that is a space where the first fin is arranged, and a second region that is a space where the first fin is not arranged. Fluid flows from the second region into the first region. The first fin includes an inflow port through which fluid flows into the first region, and an outflow port through which fluid flows out of the first region. The first fin is formed to extend from the inflow port to the outflow port. An area of the inflow port is larger than a cross-sectional area of the first fluid passage when viewed in a flow direction of fluid.

  • Patent number: 10362182
    Abstract: An image forming apparatus transmits a sheet feeding request to the sheet feeding device, obtains a sheet through a receiving device and performs image formation on the sheet. The receiving device comprises an inlet sensor for detecting a sheet fed from the sheet feeding device. The image forming apparatus transmits the sheet feeding request to the sheet feeding device again in a case where the inlet sensor does not detect a sheet within a predetermined time after the sheet feeding device starts to feed a sheet and no signal indicating an abnormality with regard to a sheet is received from the sheet feeding device. If the number of times the sheet feeding request is transmitted exceeds a predetermined number of times, the image forming apparatus stops operation.
