  • Patent number: 10486735
    Abstract: In a rotation detecting apparatus, while a switch is in an on state so that electrical power is supplied from a power source to a controller via the switch, the controller receives, as a first output signal, an output signal output from an output unit of a first rotation sensor, and receives, as a second output signal, an output signal output from an output unit of the second rotation sensor. The first output signal includes at least the first rotational information and the second rotational information based on the first rotation sensor, and the second output signal includes at least the first rotational information and the second rotational information based on the second rotation sensor. The controller determines whether there is a malfunction in each of the first and second rotation sensors as a function of the first output signal and the second output signal.

  • Patent number: 10450684
    Abstract: Disclosed is a sewing machine which evaluates sewing quality using a stitch tightness index. During sewing operation, a used length of an upper thread per stitch is detected, and a stitch tightness index per sewn stitch is calculated on the basis of a stitch length per stitch defined by sewing pattern data, a fabric thickness of a sewing workpiece, and detected data of the used length of the upper thread. Then, notification is made which corresponds to the calculated stitch tightness index per sewn stitch (such as a visual display of the stitch tightness index). After that, acceptability/non-acceptability of the thread tightness per sewn stitch can be determined by comparing the calculated stitch tightness index per sewn stitch against a reference value, and a result of the determination can be notified.

  • Publication number: 20190291775
    Abstract: An ECU, which is a signal control apparatus, has a plurality of control units, which control one same motor. Steering angle calculation units acquire sensor signals from the angle sensors provided corresponding to the steering angle calculation units, respectively, and calculate the steering angles in correspondence to the sensor signals. The angle FB units perform the angle FB control based on the angle differences, which are between the target angle and the steering angle and between the target angle and the steering angle, respectively. In the angular FB unit of at least one of the control units, the angular feedback control is performed using the angle difference, which is subjected to the correction processing to reduce the error between the detection angle of the own system and the detection angle of the other system calculated by the steering angle calculation unit of the other control unit.
