摘要:
Accurate gradation display on an OLED display device is effectuated by reducing a kickback voltage based on parasitic capacitance of a switching TFT without increasing a capacitance of a capacitor which retains a voltage to be supplied to a driving TFT. A capacitor for maintaining on-and-off states of a driving TFT which drives an OLED is charged by a switching TFT. The capacitor is connected to a scan line, which drives a switching TFT located in a preceding stage in accordance with a scanning order. After being charged by the switching TFT, a reference potential on the capacitor is raised to compensate for a drop in a gate voltage of the driving TFT attributable to parasitic capacitance of the switching TFT, in accordance with a signal from the scan line.

In a control unit for an electrical-motor-driven power steering apparatus, there are provided an assist current command value calculated based upon a steering torque of a steering wheel, an assist current control value calculated based upon a motor current value of a motor and the assist current command value. A motor outputs an assist force based upon the assist current control value. Further, the control unit provides an estimation means for estimating a road surface &mgr; based upon at least one of the motor current value and the steering torque. To the control unit, there are further inputted a vehicle speed obtained based upon rotation of a wheel, and a steering angle obtained based upon rotation of the steering wheel. Therefore, the estimation means estimates the road surface &mgr; by comparing with a previously memorized standard value corresponding to the vehicle speed and the steering angle.

Disclosed herein is a system for controlling the process of performing a command in an HDD. The HDD comprises a register for holding the command control information supplied from a host system, a command register for holding a specific command. The HDD further comprises a CPU. The CPU fetches the command control information from the register when the specific command held in the command register is one for setting the command control information. The CPU controls the process of performing a command in accordance with the command control information, thereby to finish performing the command within a period between the time when the host system issued the command and the time when the host system issues the next command.

In an ink jet printer of the type having two separate heads mounted on a carriage, alignment errors of the nozzles in the two heads occurring in the main scanning direction are reduced to improve print quality. To this end, a print paper is moved a relevant amount after the firstly actuated head completes printing of the dots during one scan and before the secondly actuated head starts printing the dots in the subsequent scan.
