Patent number: 6281648Abstract: A device for control of driving a power window automatically holds a switch in its operated state to continuously raise or lower a door glass by continuously rotating a motor. The device stops the motor when a locking current flows through the motor upon complete closure or complete open of the door glass. The device includes a thermistor inserted in a signal line through which current flowing through the motor passes. The thermistor is disposed in the vicinity of the motor. When a locking current flows through the motor, the current also flows through the thermistor so that the thermistor is heated and shuts off the current flowing therethrough so as to stop the supply of electricity to the motor when the temperature of the thermistor exceeds a predetermined value. Also, the thermistor has a function of shutting off current flowing therethrough when receiving heat radiated from the motor due to over current.Type: GrantFiled: December 13, 1994Date of Patent: August 28, 2001Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Hitoshi Iwata, Yasushi Nishibe, Kenichi Kinoshita
