  • Patent number: 10759470
    Abstract: A sensor device includes a sensor section having a plurality of sensor elements sensing a physical quantity regarding a magnetic flux collecting module, an output circuit generating and outputting an output signal including data signals respectively corresponding to sensing values from the sensor elements, and an ECU obtaining the output signal. The ECU includes an abnormality determiner identifying an abnormal sensor element. When at least two of the plurality of sensor sections respectively have at least one normal sensor element, a sub-sensor section transmits the output signal therefrom to the ECU at a shifted output timing from an output timing of the output signal from a main sensor section. The amount of such a shift of the output timing is shorter than one signal cycle of the output signal.

  • Publication number: 20200247465
    Abstract: A motor control device is provided with a plurality of power converters and a plurality of microcomputers, and controls driving of a motor that has a plurality of sets of windings. The microcomputers perform initial check of components in respective circuits after activation. The microcomputers prohibit driving of the motor by a circuit determined to be abnormal during the initial inspection. When two or more circuits are determined to be normal in the initial check, the microcomputers start driving of the motor by synchronizing the timing between the two or more circuits determined to be normal. When only one circuit is determined to be normal in the initial check, the microcomputers start driving of the motor by the one circuit determined to be normal.

    Abstract: The present technology relates to an image processing apparatus and method and an endoscopic system that permit reduction of uneven illumination distribution. An image processing apparatus includes a signal processing section that corrects uneven illumination of an image shot with a subject within a body of a patient to be operated on illuminated by a light source. The light source is arranged within the patient's body. The signal processing section corrects uneven illumination on the basis of a normally illuminated image and a low illuminated image. The normally illuminated image is shot with the subject within the body illuminated at a given illumination intensity. The low illuminated image is shot with the subject illuminated at a lower illumination intensity than the given illumination intensity.

  • Publication number: 20200112236
    Abstract: A laser welding method for a stator coil forms an abutting surface by abutting a side face of a first lead portion of a first rectangular wire to a side face of a second lead portion of a second rectangular wire. A laser beam is focused on a position more inward than a surface of an upper end of the abutting face between the first lead portion and the second lead portion, and the laser beam is moved in a helical loop on the upper end of the abutting face between the first lead portion and the second portion so as to melt the conductor wires to form a molten pool. The molten pool is then moved along the abutting face while the molten pool is continuously formed.
