  • Patent number: 7016775
    Abstract: A controller controls an electric motor to provide assist power corresponding to steering operation for an electric power steering apparatus. The controller comprises a detecting device, a filtering device, a judging device and a determining device. The detecting device detects present voltage of a power source for the electric motor. The filtering device filters the present voltage based on a small time-constant when the voltage of the power source increases and based on a large time-constant when the voltage of the power source decreases. The judging device judges whether the filtered voltage is lower than a predetermined threshold. And, the determining device determines being abnormality of the power source when it is judged that the filtered voltage is lower than the threshold.

  • Patent number: 6969907
    Abstract: A first electronic device, a second electronic device which generates less heat than the first electric device, and an electrode are connected by a heat leveling plate formed of an electrically conductive material having high thermal conductivity. A heat radiation plate is provided below an insulated substrate to which the first and second electronic devices are mounted. The second electronic device is cooled by a heat radiation path which extends through the insulated substrate and the heat radiation plate and a heat radiation path which extends through the second electronic device and the electrode to the heat radiation plate. The first and the second electronic device have substantially the same temperature due to heat radiation through the heat leveling plate. As a result, cooling effect of the electronic devices can be enhanced.

  • Publication number: 20050141827
    Abstract: An improved disconnect structure for SFP optical transceiver modules uses a slide 21 that travels relative to the module housing over a limited range. The slide 21 has operating pieces 28 which are elastically displaceable to elastically displace a spring plate 18 of the cage in a direction to release the locked state. The slide initially moves relative to the module housing to deflect the spring plate downwardly and release the locked state. When the slide then reaches the end of its range of motion relative to the module housing, further withdrawal of the slide pulls the module housing along with it, removing the module form the cage.

  • Patent number: 6886652
    Abstract: A torque distribution control device for a four-wheel drive vehicle is disclosed, wherein a torque transmitted from an engine to prime drive wheels is distributed by an electromagnetic clutch to sub-drive wheels on an on-demand basis. A pre-torque is determined based on a vehicle speed and a throttle opening degree in a feed-forward sense. A compensation torque is determined based on the rotational speed difference between the prime drive wheels and the sub-drive wheels and the vehicle speed in a feedback sense. The pre-torque and the compensation torque are added for a command torque, depending on which the electromagnetic clutch is controlled to transmit the torque from the engine to the sub-drive wheels.

  • Publication number: 20040228582
    Abstract: An optical module has a lever for bending a spring plate possessed by a cage for accommodating a case of the optical module in a direction in which a retaining hole formed through the spring plate comes off a latch formed on the case. The lever has a shaft pivotably supported on the case, a tongue disposed on one side of the shaft, and an actuator disposed on the opposite side of the shaft with respect to the tongue. The lever pivotally moves about the shaft in response to a movement of the tongue toward the case, causing the actuator to press the spring plate to bend in the foregoing direction. According to this optical module, the user can readily release retention of the latch by the retaining hole only by moving the tongue of the lever toward the case. Further, the user can withdraw the optical module from the cage through a simple manipulation of pulling the case out while the user is holding the case and the tongue of the lever together.

  • Publication number: 20040211611
    Abstract: A control device is provided for electrically controlling a drive power transmission device arranged on a driving power transmission path of a front-and rear wheel drive vehicle thereby to switch the drive mode of the vehicle selectively to either of a two-wheel drive mode and a four-wheel drive mode. The control device inhibits the drive mode from being switched to that commanded to be switched to when the vehicle is traveling at a slower speed than a predetermined speed and when the rotational speed difference between front and rear wheels is larger than a predetermined value. Further, the control device gradually decreases a present torque which the driving power transmission device is transmitting before the switching of the drive mode, to a target torque which the drive power transmission device is to transmit after the switching of the drive mode, when the difference between the present and target torques is more than another predetermined valve at the time of the switching of the drive mode.

  • Patent number: 6795762
    Abstract: A steering apparatus controller for an electric power steering apparatus, which includes an electric motor for generating assist torque for assisting steering of a steering wheel and the steering apparatus controller is designed to execute a feedback control of the applied drive voltage to the electric motor based on the detection result of the actual current that flows through the motor. A sensor detects the actual current to produce the detection result. When detecting an abnormal decrease of the drive voltage of the sensor, a voltage controller maintains the applied voltage to the electric motor at the voltage at a predetermined time before the drive voltage abnormally decreased.

  • Patent number: 6729435
    Abstract: A control apparatus of an electric power steering system has first to fourth calculators and an abnormality detector. The first calculator calculates an assist current command value, which corresponds to assist force for reducing steering force of the steering wheel, based on the steering torque of the steering wheel. The second to fourth calculators calculate a compensation current command value, which corresponds to compensation force for compensating for movement of the steering wheel, based on the angular velocity of the steering wheel that has been estimated based on the terminal-to-terminal voltage of the motor. The abnormality detector detects an abnormality of the terminal voltages of the motor. When the abnormality detector detects an abnormality, the second to fourth calculators substitute zero for the steering wheel angular velocity and then calculates the compensation current command value.
