  • Patent number: 10987949
    Abstract: A de-curling device de-curls a sheet and includes an endless belt, a de-curling roller, a nip width adjusting mechanism, and a belt tension adjusting mechanism. The endless belt is looped around a pair of supporting rollers. The de-curling roller is provided between the pair of supporting rollers and has a first outer circumferential surface pressed against a second outer circumferential surface of the endless belt to form a nip portion at which the endless belt curves along the first outer circumferential surface, the de-curling roller being configured to de-curl the sheet passing through the nip portion. The nip width adjusting mechanism adjusts the nip width by moving the de-curling roller in a direction intersecting the second outer circumferential surface of the endless belt. The belt tension adjusting mechanism adjusts the tension of the endless belt according to the nip width adjusted by the nip width adjusting mechanism.

  • Publication number: 20210096499
    Abstract: A cleaning device includes a cleaning unit and a unit moving mechanism. The cleaning unit brings a web into contact with a conveyance member rotating around an axis and removes foreign matter adhered to the conveyance member. The unit moving mechanism displaces the cleaning unit to a cleaning position where the web is brought into contact with the conveyance member and to a separation position where the web is separated away from the conveyance member. When the unit moving mechanism displaces the cleaning unit from the cleaning position to the separation position, the cleaning unit is displaced in a counter direction opposite to a rotational direction of the conveyance member on a contact face between the conveyance member and the web.

  • Patent number: 10960685
    Abstract: A controller checks ink quantity to be ejected to a specific area on a first side (specific area ink quantity) and determines an ink quantity ratio. The specific area is a strip-shaped area including a side edge on upstream side in a conveying direction of a paper sheet on the first side. When the ink quantity ratio is larger than a reference ink quantity ratio, the controller performs a black conversion process on pixels in a conversion target range. The conversion target range is a range corresponding to the specific area in the image data of the first side. The black conversion process is a process of converting a pixel to which three color inks, i.e. cyan, magenta, and yellow inks are to be ejected into a pixel to which only black ink is to be ejected.

  • Publication number: 20200398818
    Abstract: A hybrid vehicle has an engine (E) that is capable of changing a combustion mode between a stoichiometric combustion mode and a lean combustion mode and a motor/generator (MG) that is capable of performing torque assist by a power running operation and torque absorption by a regenerative operation. As a boundary between a stoichiometric combustion operating region and a lean combustion operating region, a second boundary (L2) at a torque decrease has a hysteresis at a low torque side with respect to a first boundary (L1) at a torque increase. Upon shift from the stoichiometric combustion operating region to the lean combustion operating region, for delay in increase of an intake-air quantity, decrease in fuel and the torque assist by the motor/generator (MG) are carried out, and an exhaust air-fuel ratio is changed stepwise.
