  • Patent number: 7866455
    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.

  • Patent number: 7810864
    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.

  • Patent number: 7712256
    Abstract: An opening and closing apparatus is provided with a foreign material detecting sensor, a position detecting apparatus and a control circuit apparatus. The foreign material detecting sensor has a sensor electrode, and is arranged in a front end of a door panel. The foreign material detecting sensor outputs an electrostatic capacity detection signal corresponding to a change of an electrostatic capacity between the sensor electrode and a foreign material coming close to the electrode. The position detecting apparatus outputs a position detection signal corresponding to a position of the door panel. The control circuit apparatus compares a change amount of the electrostatic capacity detected on the basis of the electrostatic capacity detection signal with a threshold value so as to judge, on the basis of a result of comparison, whether or not a foreign material exists between the door panel and a vehicle body.

  • Patent number: 7714595
    Abstract: A foreign object detection sensor applied to an electric sliding door apparatus is provided. The sensor includes a contact detecting section, a change detecting section, and a determination section. The contact detection section has a pressure sensitive portion which is capable of elastically changing in form through contact with a foreign object. The contact detecting section outputs a contact detection signal. The change detecting section measures the time required for the oscillation signal for a predetermined number of cycles to be outputted within a measurement period, which is set shorter than the response time it takes from when the object makes contact with the pressure sensitive portion to when the contact detecting section outputs the contact detection signal in the case where the movable body is in the closing operation at a predetermined maximum moving speed.
