  • Publication number: 20190299692
    Abstract: A line head type liquid discharge apparatus includes a treatment liquid applying device, a first discharging device, a heating device, and a second discharging device. The treatment liquid applying device applies a treatment liquid to a non-permeable base material. The first discharging device discharges a first ink containing an organic solvent onto the non-permeable base material to which the treatment liquid has been applied. The heating device heats, with an infrared ray, the non-permeable base material onto which the first ink has been discharged. The second discharging device discharges a second ink containing an organic solvent onto the non-permeable base material heated by the heating device. A content ratio of the organic solvent contained in the first ink is higher than a content ratio of the organic solvent contained in the second ink.

  • 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.

    Abstract: If abnormalities of the sensor part are detected, the power-source control section temporarily stops the electric power supply from the sensor power source to the sensor part so that the sensor power source voltage Vs which is the voltage between the sensor power source and the sensor part falls. In addition, after electric power supply to the sensor part resumes, and the sensor part is recovered from the abnormalities, then, the power source control section continues the electric power supply from the sensor power source to the sensor part. When the sensor part is not recovered from the abnormalities, the power source control section stops the electric power supply from the sensor power source to the sensor part.

  • Patent number: 10343714
    Abstract: A sensor device includes sensors and an Electronic Control Unit (ECU). The sensors include sensor elements, a signal comparator, and a signal transmitter. The signal comparator compares a first main detection value from one of the sensor elements, and a first sub detection value from the other of the sensor elements. When the first main detection value matches the first sub detection value, the signal transmitter generates and transmits an output signal that includes a first main signal corresponding to the first main detection value without including a first sub signal corresponding to the first sub detection value. In such manner, the responsiveness of the sensor device may be improved, without deteriorating a reliability of the output signals from the sensor sections.
