Abstract: In an automotive vehicle body including a first annular frame (29) formed by front pillars (11, 12), a second annular frame (34) formed by center pillars (13, 14) and a front door (7) internally provided with a front door beam (51) and fitted between the front pillar and center pillar one each side of the vehicle body, the front door beam overlaps the first annular frame and second annular frame as seen from sideways, and includes a door beam main body (61) providing a channel member having an open side facing inboard and a tension wire (71) extending along an inboard side of the door beam main body. Thereby, when another vehicle hits the front door from sideways, because the front door beam overlaps the first annular frame and second annular frame as seen from sideways, the impact energy can be effectively transmitted to the vehicle body. Furthermore, because the door beam main body supports a compressive load while the tension wire supports a tensile load, deformation of the door beam is minimized.

The control unit also controls lighting-on and lighting-off of the light emitting elements in sync with rotary movement of the first optical system and according to image information to be displayed, thereby the second optical system converging the light to produce the image information.

Abstract: A display device includes an ultraviolet light source, a color light source, and a filter selectively hit by their lights. The filter has a first area part for displaying the first display contents excluding an overlapped parts when the ultraviolet light is emitted, a second area part for the second display contents excluding the overlapped parts when the color light is emitted, and a third display part for displaying the overlapped parts when one of the ultraviolet and color light is emitted. The first area part blocks the color light and produces visible light when the ultraviolet light hits the first area part, the second area part allows the ultraviolet and color lights to pass therethrough, and the third area part allows the ultraviolet and color lights to pass therethrough and produces the visible light when the ultraviolet light hits the third area part.

Abstract: A semiconductor device is manufactured using a SiC substrate. On a semiconductor region a region formed of SiC having an (11-20) face orientation is formed. A gate insulation layer is a gate oxidation layer. The surface of the semiconductor region is cleaned, and the gate insulation layer is formed in an atmosphere containing hydrogen or water vapor. After the gate insulation layer has been formed, the substrate is heat-treated in an atmosphere containing hydrogen or water vapor. This reduces the interface-trap density at the interface between the gate oxidation layer and the semiconductor region.

Abstract: An MIS transistor that uses a silicon carbide substrate has a buried channel structure. The surface orientation of the silicon carbide substrate is optimized so that the device does not assume a normally on state, has good hot-carrier endurance and punch-through endurance, and high channel mobility. In particular, a P-type silicon carbide semiconductor substrate is used to form a buried channel region. To achieve high mobility, the depth at which the buried channel region is formed is optimized, and the ratio between buried channel region junction depth (Lbc) source and drain region junction depth (Xj) is made to be within 0.2 to 1.0. The device can be formed on any surface of a hexagonal or rhombohedral or a (110) surface of a cubic system silicon carbide crystal, and provides a particularly good effect when formed on the (11-20) surface.
