    摘要: A paper conveyance device includes: an upstream roller and a downstream roller being arranged at an interval in a paper conveyance path; paper conveyance guides being arranged between the upstream and downstream roller in the paper conveyance path to guide both surfaces of paper along the paper conveyance path during paper conveyance; drivers that drive the upstream and downstream roller independently; and a processor that measures the load torques on the upstream and downstream roller, that judges whether or not the paper is rubbing against one of the paper conveyance guides with reference to the load torques on the upstream and downstream roller, the load torques being obtained by the processor, and that performs controlled paper conveyance with reference to the load torques on the upstream and downstream roller depending on the result of the judgment being obtained by the processor.

    摘要: A controller for a permanent magnet synchronous motor having a rotor using a permanent magnet includes a drive portion configured to apply a current to a winding to drive the rotor; an estimating portion configured to estimate a position of magnetic pole of the rotor; and a control unit configured to control the drive portion to cause the rotating magnetic field based on the estimated position of magnetic pole and to control the drive portion to stop the rotor in response to a stop command inputted. The control unit controls, as the control to stop the rotor, the drive portion to determine a current for generating a magnetic field vector which draws the position of magnetic pole of the rotor to a stop position to stop the rotor based on a latest estimated position of magnetic pole, and to keep applying the current determined to the winding.

    摘要: A charge control device uses external electricity to charge a plurality of battery devices. A constant current source uses the external electricity to generate and adjust an output current amount to a constant target value. A selector selects one battery device from the plurality of battery devices and supplies output current from the constant current source to the one battery device. A measurer measures an amount of actual current flowing from the constant current source to the one battery device. An instructor monitors a measured value provided by the measurer and instructs the selector, when the measured value meets a condition for a reduction of charging current amount to be regarded as having occurred, to change a destination to which the output current of the constant current source is supplied from the one battery device to a different battery device.
