20150372480 | OPEN-CLOSE BODY CONTROL APPARATUS - A motor is driven to rotate in a closing direction in an ordinary region other than a full close position immediately ahead region. An interposition determination unit determines whether or not interposition occurs while a windowpane is closing. If the interposition determination unit determines that interposition occurs, the motor is driven in a reverse direction to open the windowpane by a predetermined amount. The interposition determination unit continuously determines interposition after the closing windowpane enters the full close position immediately ahead region. If the determination unit determines that the interposition occurs while the windowpane is closing in the full close position immediately ahead region, the control unit stops driving the motor to stop the windowpane. | 12-24-2015 |

20130134816 | ROTOR FOR MOTOR AND METHOD FOR MANUFACTURING THE SAME - Non-holding portions of a holding ring are demagnetized by supplying a nonmagnetic element to the non-holding portions while melting the non-holding portions by the application of heat. Each non-holding portion is demagnetized such that, from the melting center toward each melting end portion thereof, the material of the non-holding portion moderately changes from a nonmagnetic material to a ferromagnetic material.
