  • Publication number: 20190238885
    Abstract: A moving image encoding/decoding system may include a video predictive encoding device, which may include: an encoding device which encodes each of a plurality of input pictures to generate compressed picture data including a random access picture, and encodes data about display order information of each picture; a restoration device which decodes the compressed picture data to restore a reproduced picture; a picture storage device which stores the reproduced picture as a reference picture; and a memory management device which controls the picture storage device. Following completion of an encoding process of generating the random access picture, the memory management device refreshes the picture storage device by setting every reference picture in the picture storage device, except for the random access picture, as unnecessary immediately before or immediately after encoding a picture with display order information larger than the display order information of the random access picture.

  • Publication number: 20190193789
    Abstract: A steering angle calculating circuit includes a first neutral point calculating circuit, a second neutral point calculating circuit, and an absolute angle calculating circuit. The first neutral point calculating circuit calculates a motor neutral point (?m01), based on a steering angle detected by a steering sensor and a rotation angle of a motor detected by the relative angle sensor, when a drive source for driving a vehicle is started. The second neutral point calculating circuit calculates a motor neutral point when the steering angle detected by the steering sensor falls within a predetermined angle range in which a specific stroke with respect to the steering angle is constant. After the motor neutral point is calculated by the second neutral point calculating circuit, the absolute angle calculating circuit calculates the steering angle as an absolute angle, using the motor neutral point calculated by the second neutral point calculating circuit.

A voltage corrector corrects, for each of the first and second motor control cycles, the voltage command based on the voltage correction. A correction voltage feedback unit feeds back a value of the voltage correction calculated at the first motor control cycle to a voltage command calculator. The voltage command calculator calculates a value of the voltage command for the second motor control cycle based on the value of the voltage correction fed back from the correction voltage feedback unit in addition to a value of the motor current parameter and a predetermined current command.

  • Publication number: 20190181239
    Abstract: When a film thickness of a second epitaxial film is measured, an infrared light is irradiated from a surface side of the second epitaxial film onto a base layer on which a first epitaxial film and the second epitaxial film are formed. A reflected light from an interface between the first epitaxial film and the base layer and a reflected light from a surface of the second epitaxial film are measured to obtain a two-layer film thickness, which is a total film thickness of the first epitaxial film and the second epitaxial film. The film thickness of the second epitaxial film is calculated by subtracting a one-layer film thickness, which is a film thickness of the first epitaxial film, from the two-layer film thickness.
