  • Publication number: 20190213975
    Abstract: A plurality of drawing nodes 34 draw, in parallel, a plurality of individual images to be displayed in a plurality of individual regions obtained by dividing a frame display region. A display control node 36 generates a synthetic image obtained by synthesizing together the plurality of individual images drawn by the plurality of drawing nodes 34 and causes the synthetic image to be displayed on a display device 38. In the case where the individual image of at least one individual region is delayed at a frame processing timing, the display control node 36 generates a synthetic image as an individual image of that individual region by applying the individual image of the previous frame.

  • Patent number: 10014746
    Abstract: In a rotary electric machine, wound wires are connected to a first terminal and a second terminal. Circuit terminals that are configured from a conductive metal other than aluminum, and the first terminal and the second terminal that are configured from a metal with a principal component of aluminum are joined together inside a circuit chamber that has high water resistant properties. Corrosion is accordingly suppressed at join sites of the circuit terminals with the first terminal and the second terminal. There is therefore no need to coat the join sites with for example a sealing material in order to suppress corrosion at the join sites. Good electrical continuity is accordingly enabled between the circuit terminals and the wound wires while suppressing an increase in costs, even when the wound wire is configured from a metal with a principal component of aluminum.

  • Patent number: 9804191
    Abstract: An inverted two-wheel vehicle includes: an inverted two-wheel vehicle body; an acceleration sensor and a gyro sensor which are mounted on the same substrate; and an ECU. The ECU calculates a mounting angle error of the acceleration sensor with respect to the inverted two-wheel vehicle body based on an output value of the acceleration sensor obtained when the inverted two-wheel vehicle is brought into a stationary state in a state where a reference yaw axis of the inverted two-wheel vehicle is made coincident with a vertical direction, and corrects an output value of the gyro sensor by using the mounting angle error of the acceleration sensor with respect to the inverted two-wheel vehicle body as a mounting angle error of the gyro sensor with respect to the inverted two-wheel vehicle body.

  • Patent number: 9478503
    Abstract: An integrated device with high insulation tolerance is provided. A groove having an inclined side surface is provided between adjacent devices. When a side where an electronic circuit or MEMS device is mounted is a front surface, the groove becomes narrower from the front surface to a back surface because of the inclined surface. A mold material (insulating material) is disposed inside the groove, so that the plurality of devices are mechanically joined together, being electrically insulated from one another. A line member that establishes an electrical conduction between the adjacent devices is formed to lie along the side surface and the bottom surface of the groove. To lead the line out to the backside, the bottom surface of the groove has a hole, so that the line member is exposed to the backside from the hole.
