  • Printing apparatus having optical sensor unit
    Patent number: 8152167
    Abstract: A printing apparatus has a sensor unit which optically detects, at a measurement position, a surface of a sheet, for measuring a moving state of the sheet. The sensor unit measures the moving state of the sheet when the sheet is located at the measurement position, and measures a moving state of a surface of the rotary member when the sheet is not located at the measurement position. The sensor unit has at least one of an image sensor arranged to perform imaging of one of the surface of the sheet and the surface of the rotary member so as to obtain image data, based on which the moving state is measured and a Doppler velocity sensor.

  • PRINTING APPARATUS
    Publication number: 20110261102
    Abstract: An apparatus includes a printing unit and a drying unit. The printing unit performs printing on a sheet using ink. The drying unit dries the sheet on which the ink is applied at the printing unit as the sheet is conveyed in the drying unit. The drying unit causes hot air heated by a heater to circulate through a housing and blows the hot air to the sheet. The housing includes an opening through which movement of gas between inside and outside the housing can be adjusted. When conveyance of the sheet in the drying unit stops, the apparatus is controlled to reduce an output of the heater and to increase the movement of the gas through the opening.

  • STEERING CONTROL APPARATUS FOR VEHICLE
    Publication number: 20110257845
    Abstract: A coordinate-control-gain calculation section 61 calculates a coordinate-control final control torque T_C required to properly control the traveling behavior of a vehicle, and determines a coordinate control gain Kg on the basis of the magnitude of this torque T_C. An arbitration-request determination section 62 determines the value of an arbitration request flag FRG_A on the basis of the magnitude of the torque T_C and the value of a flag FRG_L output so as to properly control the traveling behavior of a vehicle. On the basis of the value of the flag FRG_A and the magnitude of the coordinate-control arbitration torque Tr determined by use of the gain Kg, an arbitration section 63 selects the torque T_C or the torque Tr to be output as a post-arbitration control torque T_F. A post-arbitration drive control section 64 supplies to an electric motor a drive current corresponding to the determined torque T_F.

  • ENGINE STARTING SYSTEM WITH HIGH-AND LOW-SPEED MODES OF MOTOR OPERATION
    Publication number: 20110221210
    Abstract: An engine starting apparatus includes a first and a second power supply path extending from a battery to an electric motor to start an engine. An electromagnetic switch has main contacts disposed in the first power supply path. A resistor is disposed in the second power supply path. A motor relay has relay contacts disposed in series with the resistor. A controller delays the time when the main contacts are closed to apply a full voltage of the battery to the motor until a given time lag has elapsed after the relay contacts are closed to supply electric current to the electric motor through the resistor. Specifically, when it is required to apply the full voltage to the motor to run the motor at a rated speed, the current does not pass through the relay contacts, thus resulting in no voltage drop, which ensures the stability in starting the engine.
