    摘要: Two sensors are provided on a clutch core. Sensor coils are driven at a high frequency by a high-frequency driving circuit. As the sensors sense a magnetic flux of a magnetic circuit including the clutch core and an armature, the impedance of the sensor coils changes. In accordance with the outputs from the sensor coils at this point, an impedance detecting circuit detects the impedance of the sensor coils. Then, an impedance combining circuit combines the impedance of the sensor coils. On the basis of the combined impedance, a current control circuit controls a current supplied to an exciting coil. Thus, the attracting force of the armature to the core excited by the exciting coil is controlled.

    摘要: The differential includes a differential casing configured to be rotatably driven by a motor under a driving force. The differential includes a differential mechanism which includes a pair of first and second side-gears for distributing a torque of the differential casing to first and second output shafts. The differential includes a frictional clutch for interconnecting the first and second output shafts. The frictional clutch includes first and second power-transmitting members connected to first and second output shafts respectively and first and second clutch plates. The first and second clutch plates are connected to the first and second power-transmitting members respectively. The differential includes an actuator for operating the frictional clutch. One output shaft of the first and second output shafts is axially displacable by the actuator under an engagement force to engage the frictional clutch.

    摘要: The present invention aims at avoiding a hung-up in the case where a command is sent from a controller within a printer but there is no response to the command from the unit side within the printer, due to a faulty communication or the like, and also in the case where a noise is introduced in the communication data. In the present invention, based on a command sent to the unit side, a data amount of a response from the unit side to this command is predicted, and also a threshold value of response time is provided (S21), which is the time when from the command is sent until the time when the response is received. After the command is sent (S23) until the threshold value of the response time elapses, the receive data is sequentially stored in the receive buffer up to when the data amount from the unit side reaches the predicted data amount (S28, 32, 34). If the data amount from the unit side does not reach the predicted amount even after the lapse of threshold value of the response time, an error processing is executed (S43, 45, 47).
