    摘要: Route costs are computed using the Dijkstra algorithm based on link information and connection information and a destination route is set based on a connection of links which has the least route cost. The route cost is set to sub-nodes of each connection link. Therefore, optimal routes can be set even though traffic regulations such as no right turns or the like exist on certain nodes.

    摘要: An information center has an all-road updating data and a main-road updating data. The all-road updating data is a difference of all roads extracted from an all-road map data, and the main-road updating map data is a difference of specified roads extracted from the all-road map data. A map display system executes a reverse-updating to return the map data to a previous state not updated with the main-road updated map data, when its map data has already been updated with the main-road updated map data. The map display system then executes updating of the map data with the all-road updated map data.

    摘要: This invention provides a light-emitting element that comprises a light-emitting portion made of a nitride semiconductor; and a first wavefront converter for converting the radiated shape of light that is emitted from the light-emitting portion into a radiated shape that is smaller than the wavelength thereof, and emitting the same as output light. In this case, the first wavefront converter has a small aperture of a diameter that is smaller than the wavelength of light that is emitted from the light-emitting portion. If the output light is made to comprise an evanescent wave that is emitted to the exterior through this small aperture, it is possible to obtain an extremely small light spot. This invention also relates to a surface-emitting type of light-emitting element comprising a multi-layered structure comprising a light-emitting layer; and a pair of electrodes for supplying a current to the light-emitting layer; wherein output light is emitted from a light-emitting surface on top of the multi-layered structure; and the pair of electrodes are recessed from the light-emitting surface to the light-emitting layer side. This makes it possible to bring the light-emitting surface extremely close to an object to be illuminated. The small aperture can be opened up in a self-aligning manner by using the light from the light-emitting portion. As a result, it is possible to provide a light-emitting element and a method of fabrication thereof that create beam characteristics that are suitable for use with an optical disc or the like.

    摘要: When a vehicle is within a predetermined distance from an intersection during the execution of navigation operations, a navigation system displays an enlarged guide map of the same intersection. The guide map shows direction labels that are set for roads that are connected to a road to be approached by the vehicle. The direction labels are set for the connecting roads by tracking the connecting roads and by determining appropriate direction labels following a predetermined procedure. For example, names of tollgates, names of stations, names of special facilities, names of administrative units, names of highways or the like may be set as direction labels.
