20110167944 | DRIVING FORCE TRANSMISSION APPARATUS AND CONTROL METHOD THEREFOR - A driving force transmission apparatus includes: a driving force transmission shaft receiving driving force of a driving source from a rotating member and transmitting the driving force from a main driving wheel side to an auxiliary driving wheel side; a first driving force interruption unit connects/disconnects the driving force transmission shaft to/from the rotating member; a second driving force interruption unit connects/disconnects the driving force transmission shaft to/from at least one of two auxiliary driving wheels so that transmitted torque is variable; and a control unit controls connection and disconnection of the first and second driving force interruption units. The control unit causes the second driving force interruption unit to connect/disconnect the driving force transmission shaft to/from the at least one of the auxiliary driving wheels before causing the first driving force interruption unit to connect/disconnect the driving force transmission shaft to/from the rotating member. | 07-14-2011 |
20130226421 | FOUR-WHEEL-DRIVE VEHICLE AND CONTROL UNIT - A four-wheel-drive vehicle includes: a drive source which generates torque forming a driving force of the vehicle; a driving force transmission system which transmits the torque of the drive source to main driven wheels and auxiliary driven wheels; and a dog clutch provided in the driving force transmission system and capable of transmitting the torque to an auxiliary driven wheel side by engagement of a recess portion and a protruding portion. The vehicle further includes: a determination unit which determines whether a friction coefficient of a road surface is lower than a predetermined value based on an index value relating to the friction coefficient of the road surface; and a control unit which generates a control signal which causes engagement of the dog clutch before the vehicle starts when the determination unit determines that the friction coefficient of the road surface is lower than the predetermined value. | 08-29-2013 |
20130274055 | FOUR-WHEEL DRIVE VEHICLE - A four-wheel drive vehicle includes: a driving force transmission system which transmits torque of a drive source to front wheels and rear wheels via gear mechanisms; a clutch provided in the driving force transmission system and capable of controlling an amount of the torque transmitted to the rear wheels; and a pressing mechanism which presses the clutch by transforming a part of the torque transmitted to the rear wheels into axial thrust. In the driving force transmission system, gear ratios of the gear mechanisms are set such that a direction of a differential rotation between a drive shaft connected to an input side of the clutch and a drive shaft connected to an output side of the clutch is not reversed even when a steered angle of the front wheels changes to a maximum value while the four-wheel drive vehicle is traveling forwards. | 10-17-2013 |

20120305621 | CONVEYANCE DEVICE, PRINTING DEVICE, AND CONVEYANCE METHOD - A conveyance device including an upstream roller that supplies a sheet medium to be processed to a conveyance path; a downstream roller that conveys the supplied medium to a processing position; and a control unit that controls driving the upstream roller and the downstream roller to convey the sheet medium at a constant speed. The control unit determines the starting time of the upstream roller and the downstream roller when starting the conveyance operation based on specific information about the upstream roller and the downstream roller in a previous conveyance operation. | 12-06-2012 |
20120312855 | CONVEYANCE DEVICE, PRINTING DEVICE, AND CONVEYANCE METHOD - A conveyance device including an upstream roller that supplies a sheet medium to be processed to a conveyance path; a downstream roller that conveys the supplied medium to a processing position; and a control unit that, in order to convey the sheet medium at a constant speed, controls driving the upstream roller and the downstream roller using the constant speed as a target speed. The control unit changes the target speed of the upstream roller to eliminate a conveyance difference, which is the difference between the length of media conveyed by the upstream roller and the length of media conveyed by the downstream roller from the start of the conveyance operation, based on the conveyance difference in each conveyance operation. | 12-13-2012 |

20130028647 | Conveyance Device, Printing Device, and Conveyance Method - A conveyance device including a drive roller that feeds a sheet medium from a media roll having the sheet medium wound in a roll that can rotate on a center axis of the roll, a drive roller that supplies the sheet medium from the media roll, a roll rotating unit that rotates the media roll and rewinds the supplied sheet medium, and first and second brake devices that apply a load to rotation of the media roll and are disposed to the roll rotating unit, wherein the first brake device is controlled to apply the load when not energized. | 01-31-2013 |
20140192108 | Printer With Mechanism For Controlling Recording Medium Tension - A printer has a mechanism to counter change in the tension of the recording medium to convey the recording medium with more precision. Such printer has a media conveyance mechanism that conveys a recording medium; a printhead that prints on the medium; a media supply mechanism that supplies the medium to the media conveyance mechanism; a movable member that can move to compensate and thus counter internal tension changes in the recording medium resulting from operation of the media conveyance and supply mechanisms; a detector that detects the movement or position of the movable member; and a control unit that controls the media supply operation based on output from the detector so that the movable member is urged back to or maintained in a home position. | 07-10-2014 |
