Abstract: A method and apparatus for reliably determining an optimal route between a departure point and a destination in an exploration object zone, the optimal route being determined according to the situation of roads separating the departure point and the destination. Prior to route exploration, an area determiner counts the total number of intersection network lists associated with a route exploration object zone, which lists are stored in a route exploration memory. When a density of intersections (which is the total number of intersection network lists divided by the size of the route exploration object zone) exceeds a certain value, the area determiner determines that the object zone lies in an urban (high road density) district. When the density of intersections is smaller, the area determiner determines that the object zone lies in a suburban (low road density) district. When the area determiner determines that the object zone lies in an urban district, an optimal route explorer executes heuristic exploration; that is, it uses intersection network lists to explore an optimal route linking a departure point and a destination while trimming away routes that deviate from the direction specified with a straight line joining the departure point and destination or while lowering the priorities of such routes. When the area determiner determines that the object zone lies in a suburban district, the optimal route explorer executes normal non-heuristic (exhaustive) exploration.

Abstract: To provide an electron tube having good airtightness and being appropriate for mass production, indium affixed to the inner surface of a sealing metal support member is provided between a side tube and input faceplate. The input faceplate is pushed against the side tube. As a result, the indium is squeezed by a pressure receiving surface provided on the end face of the side tube. Since the pressure receiving surface is in a generally declining shape from the inside out, the force of the pressing surface causes the indium to flow outward toward the sealing metal support member. Therefore, the indium is firmly affixed to the pressure receiving surface, and the side tube and input faceplate can be reliably sealed by the indium.

Abstract: Accurate detection of an existing link (current road location between two road nodes) of a vehicle by an on-board navigation system. Upon each periodic detection of the position, azimuth and velocity of the vehicle by a GPS receiver, all the links within a predetermined distance of the vehicle position are extracted by looking up road data read out from a CD-ROM. For each of the links, the distance from the vehicle position, the angle with the vehicle azimuth, the angle between the vehicle azimuth and a passable direction of the link, the difference between the vehicle velocity and the speed limit for the link and the connectability with the last-detected existing link are obtained and are substituted into a predetermined existential probability evaluation function to calculate an existential probability. The link with the largest existential probability is determined to be the existing link. This existing link and guide route data in a guide route memory are collated to determine any deviation from the guided route. If a deviation has occurred, a warning character sequence pattern is generated and displayed on a map image on a screen.
