  • Publication number: 20220251895
    Abstract: A power window device includes a control unit configured to: monitor independently a first potential at one ends of a first switch circuit including a window closing switch and a second switch circuit including a window opening switch and a second potential at one end of a submersion detection sensor, and determine that submersion has occurred when the second potential is in a submersion potential range. During a normal time, the control unit outputs a window closing command signal when the first potential is a potential at a time of the window closing switch being operated, and outputs a window opening command signal when the first potential is a potential at a time of the window opening switch being operated. At a time of submersion, the control unit does not output the window closing command signal, and outputs the window opening command signal.

  • Patent number: 10281848
    Abstract: An improved image forming apparatus includes an image bearer, a nip forming member, a transfer power source, and a controller. The controller switches a transfer mode between a first mode to transfer the toner image onto a first type sheet having a surface smoothness higher than a surface smoothness of a second type sheet and a second mode to transfer the toner image onto the second type sheet. The controller controls the transfer power source to output the transfer bias having an opposite-peak duty of greater than or equal to 50% that is a duty on the side of the opposite-peak value in the first mode. The controller controls the transfer power source to output the transfer bias having an opposite-peak duty of less than 50%, which is different from the opposite-peak duty of the first mode, in the second mode.
