Patent number: 10641386Abstract: In an automatic transmission control device of the invention configured to start an increase in engagement pressure of a start-up engagement element, when a determination threshold value for determining that a turbine rotational speed has reduced is reached or exceeded, the determination threshold value when a selection operation from a non-traveling range to a traveling range is made before a prescribed period of time from starting of an engine has elapsed, is increased and set greater than the determination threshold value when the selection operation is made after the prescribed period of time has elapsed. Accordingly, a reduction in the turbine rotational speed can be accurately determined, and thus it is possible to suppress torque fluctuations, occurring owing to engagement of a second brake, which is the start-up engagement element.Type: GrantFiled: October 21, 2016Date of Patent: May 5, 2020Assignee: JATCO LTDInventors: Ryosuke Fujii, Hiroaki Shiokawa

Patent number: 10459389Abstract: Conventionally, it has been impossible to adjust a transportation direction magnification correspondingly to jobs, causing an image to be formed in an unintended size, while the transportation direction magnification for the image formed on the sheet varies with jobs. A controller included in an image forming apparatus selects an image adjustment chart used to adjust a transportation direction magnification that varies with job conditions of a job to be executed currently in a transportation direction of images transferred to sheets by a transferrer.
