  • Publication number: 20080245636
    Abstract: When a drive shaft is in a non-drive state, a second drive rotor is in a non-engaged state with a driven rotor with respect to its own rotating direction. When the drive shaft is in a drive state, a rotating force of a first drive rotor is transmitted to the second drive rotor through an urging member. As a result, a power transmitting member revolves, and a centrifugal force arranges the power transmitting member at a second clamping position. The second drive rotor receives a reaction force from a driven rotor via the power transmitting member. As a result, the second drive rotor is relatively rotated in an opposite direction to a rotating direction of the first drive rotor with respect to the first drive rotor, against an urging force of the urging member. As a result, the first drive rotor is engaged with the driven rotor with respect to its own rotating direction. Accordingly, the clutch is stably operated.

    Abstract: An opening and closing device includes an electrically conductive fixed body, a movable body, a drive motor, a speed control device, a detection assembly, and a determining device. The electrically conductive fixed body defines an opening portion therein. The movable body is displaceable between a full closed position and a full open position. The drive motor drives the movable body to open and close the opening portion of the fixed body. The detection assembly includes a sensor electrode. The determining device computes, as a detection value, a change amount of the capacitance at the sensor electrode per a predetermined constant measuring time based on the change of the capacitance detected by the sensor electrode. The determining device compares the detection value with a constant threshold value, and determines whether the object exists between the movable body and the periphery of the opening portion based on the comparison result.
