  • Patent number: 10894432
    Abstract: A printing apparatus comprises a conveyance control unit which controls conveyance of printing sheets so that a trailing edge of a preceding sheet as a printing sheet precedingly fed from the stacking unit and a leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other; and a skew correction unit which performs skew correction of the succeeding sheet while the succeeding sheet overlaps the preceding sheet by the conveyance control unit. The skew correction unit makes the leading edge of the succeeding sheet abut against the conveyance roller during a time from an end of a last line feed operation by the conveyance roller for printing on the preceding sheet by the printing unit to start of a next conveyance operation.

  • Patent number: 10689550
    Abstract: A composition exhibits excellent heat resistance and mounting reliability when bonding a semiconductor power element to a metal lead frame, which is also free of lead and thereby places little burden on the environment. An electrically conductive composition contains at least a sulfide compound represented by R—S—R? (wherein R is an organic group containing at least carbon; R? is an organic group that is the same as or different from R; and R and R? may be bonded to each other to form a so-called cyclic sulfide) and metal particles containing at least Cu, Sn or Ni as its essential component. Further, a conductive paste and a conductive bonding film each are produced using the electrically conductive composition. A dicing die bonding film is obtained by bonding the conductive bonding film with an adhesive tape.

  • Patent number: 10569560
    Abstract: An inkjet printing apparatus includes a print head, an ink tank containing ink to be supplied to the print head, a cap switchable between a covering position to cover a discharge port face and an exposing position to expose the discharge port face, a suction unit connected to the cap, and a control unit. The control unit controls the performing of an ink filling operation of filling the print head with the ink supplied from the ink tank. The ink filling operation includes a valve-closing suction operation of performing suction through the suction unit for a predetermined period of time while the cap is in the covering position. The apparatus further includes a detection unit configured to detect an ink filling state. The control unit controls the stopping of the ink filling operation in accordance with a detection result of the detection unit.
