    摘要： Characteristic parameters of a torque of a stepping motor and its associated driving current or voltage are measured in advance to providetorque vs. characteristic information data representative of the torque vs. driving current/voltage characterisitcs. Then, the above characteristic parameters are measured again when a real load is applied to a stepping motor as installed with associated mechanical coupling components. An actual load torque is determined by referencing the subsequently measured characteristic parameters to the previously obtained torque vs. characteristic information data. A load inertia moment can be determined by subtracting the motor's rotor inertia moment from a determined inertia moment of the entire system. Efficiency of the motor can be determined by multiplying the output of the measured load torque by the nuber of revolutions per second thereof and dividing this by the power supplied to the motor or driving circuit. Backlash can be determined from the play in the changes of associated current waveforms corresponding to particular intervals, i.e., an interval from when the direction of rotationof the motor is changed to when the load torque increases again.

    摘要： An image processing system includes an image reader unit which reads an image so as to generate it as 4-bit data, and a communication unit for converting the 4-bit data into 6-bit data. The communication unit forms the 6-bit data in such a manner that an upper 2-bit component of the 4-bit data is added to the 4-bit data as a lower 2-bit component of the 6-bit data. The resultant 6-bit data is supplied to a binary printer and is subjected to halftone processing and printing. Image signals having different bit numbers can be processed and excellent image reproduction can be achieved with a simple system.
