  • Patent number: 11927466
    Abstract: A physical quantity measurement device is configured to seal a cavity portion on a back surface side of a diaphragm of a thermal air flow rate sensor while improving measurement accuracy. The device may include a lead frame having a mounting surface on which a flow rate sensor which is the thermal air flow rate sensor is mounted, and a flow passage forming member disposed on a back surface opposite to the mounting surface of the lead frame. A ventilation flow path is formed by a first through hole in communication with a cavity portion of the flow rate sensor, a second through hole provided in the lead frame and opened in the mounting surface, and a connection flow path that is defined between the lead frame and the flow passage forming member and connecting the first through hole and the second through hole.

  • Patent number: 6814394
    Abstract: A door is moved in an opening direction at a first speed until the door reaches a decelerating area. A moving speed of the door in the opening direction is decelerated from the first speed to a second speed being lower than the first speed while the door has been moved in the decelerating area. The movement of the door is stopped when the door is moved beyond the decelerating area, the door comes in contact with an obstacle, and the moving speed of the door becomes lower than a predetermined speed corresponding to an open position of the door by a predetermined threshold value.

  • Patent number: 6739646
    Abstract: A vehicle is provided with an opening and closing device for opening and closing the vehicle door. A hook mechanism holds the door in an open condition, an electric releasing actuator is operatively connected to the hook mechanism to unhook the hook mechanism for permitting the door to be moved in the closing direction, an electric driving device is adapted to move the door in the closing direction, and an operation device generates a signal for directing that the door be moved in the closing direction. In addition, a control device controls the operation of the electric releasing actuator based upon the signal from the operation device, and controls the electric driving device to initiate driving operation of the electric driving device after initiation of the operation of the electric releasing actuator.

  • Patent number: 6580243
    Abstract: A door speed is detected at every predetermined detecting time, and a door position is calculated at a timing detected the door speed. A target speed according to the door position is obtained by a map. A microcomputer calculates a speed difference &Dgr;VD between the target speed and the actual or present speed, and an acceleration/deceleration value &Dgr;VC such as the speed difference between the door speed at the last detecting time and the present detecting time. A duty increasing value and the decreasing value of a PWM duty command value for adjusting a torque of the motor are set based on the speed difference &Dgr;VD and the acceleration/deceleration value &Dgr;VC, the motor is driven by the PWM duty command value based on the duty increasing value and the decreasing value.
