A method for producing a vertical-cavity surface-emitting laser, includes the steps of: forming a bottom mirror layer, an active layer and a top mirror layer on a semiconductor substrate; forming an antireflection layer on a rear surface of the semiconductor substrate; selectively etching peripheral portions of the antireflection layer to form a first electrode; defining laser emission portions th...

An on-board vehicle navigation apparatus which gives road directions to a driver which accurately describe the road conditions beyond an intersection at which to turn, without causing any confusion even if the route is complicated. A route planning section 9 determines a route based on the current position of the vehicle which is obtained through a current position determination section 2 and a de...

An input unit for navigation systems which easily inputs positional information for a destination point and so on. When discrimination information for a designated section of a map is input by an input device and representative points of the section and a certain point within the section are designated by using a transparent tablet overlaid on the map, a CPU, by reference to a map data base, calcu...
