  • Patent number: 10437060
    Abstract: [Object] To provide an image display system that displays an image with a wide field of view while reducing VR sickness. [Solution] When a field of view FOVO of an original image provided by an image output device (200) is greater than a field of view FOVD of an image viewed by a user wearing an image display device (300), the image output device (200) cuts out a region with the field of view FOVD from the original image for delivery to the image display device (300). Also, when the field of view FOVO of the image viewed by the user wearing the image display device (300) is equal to or greater than the field of view FOVD of the original image provided by the image output device (200), the image output device (200) delivers the original image as-is to the image display device (300).

  • Patent number: 10403749
    Abstract: In a first main surface side of a silicon carbide semiconductor base, a trench is formed. A second base region of a second conductivity type is arranged at a position facing the trench in a depth direction. An end (toward a drain electrode) of the second base region of the second conductivity type, and an end (toward the drain electrode) of a first base region of the second conductivity type reach a position deeper than an end (toward the drain electrode) of a region of a first conductivity type. Thus, the electric field at a gate insulating film at the trench bottom is mitigated, suppressing the breakdown voltage of the active region and enabling breakdown voltage design of the edge termination region to be facilitated. Further, such a semiconductor device may be formed by an easy method of manufacturing.

  • Patent number: 10403713
    Abstract: In a first main surface of a silicon carbide semiconductor base, a trench is formed. On a first main surface side of the silicon carbide semiconductor base, an n-type silicon carbide epitaxial layer is deposited. In a surface of the n-type silicon carbide epitaxial layer, an n-type high-concentration region is provided. In the surface of the n-type silicon carbide epitaxial layer, a first p-type base region and a second p+-type base region are selectively provided. The second p+-type base region is formed at the bottom of the trench. A depth of the n-type high-concentration region is deeper than that of the first p-type base region and the second p+-type base region. Thus, by an easy method, the electric field at a gate insulating film at the bottom of the trench is mitigated, enabling the breakdown voltage of the active region to be maintained and the ON resistance to be lowered.
