摘要： A stepping motor driving system includes: a stepping motor that rotates at a predetermined angle according to a driving pulse signal, a vibration detector that detects vibration to output a vibration signal, and a stepping motor control unit that controls the driving pulse signal, which is applied to the stepping motor, to rotate the stepping motor at the predetermined angle. The driving pulse signal includes a start-up current which is required for rotating the stepping motor at a unit angle and a holding current which maintains a rotational angle of the stepping motor rotated by the start-up current. The stepping motor control unit changes the level of the holding current according to the vibration signal which is outputted from the vibration detector.

摘要： In controller for diesel electric locomotive, after output from an alternating current generator driven by a diesel engine is rectified into direct current power, the direct current power is inverted into alternating current power by an inverter to thereby carry out a power run control of an induction motor, and energy generated by the induction motor is consumed at a brake resistor by moving a brake chopper when the brake is applied. When a revolving speed of said induction motor exceeds a predetermined value at the time of power run, an slip control unit detects slip of wheels and outputs an output reduction signal for the induction motor in correspondence to a level of slip. An output torque of the induction motor is reduced with the output reduction signal. Further, a reduced amount of the output torque of the induction motor is consumed at a brake resistor through a conduction ratio control of the brake chopper.

摘要： A recording and reproducing apparatus has a recording and/or reading head having a tip for recording and/or reproducing information on and/or from a recording medium. Information is recorded and/or erased by way of a polarization reversal or transport of electric charges in a predetermined area of the recording medium in response to application of a pulse voltage from the head. The information recorded in the predetermined area is detected as a change in the electric charges or an electrostatic capacitance or a surface potential or their differential in the predetermined area for reproducing the information.
