Filed: 1986-05-09
Abstract: PURPOSE:To reach a destination securely in safety by displaying the ratio of the running speed of a vehicle and the destination directional component at the running speed on a display device at intervals of unit time or unit run distance. CONSTITUTION:An arithmetic controller 5 performs readout and display control over specific storage contents from a storage device 3 at the time of initial setting according to an indication from a keyboard 4, and computes the straight distance between the destination and current position from coordinate points corresponding to the destination and current vehicle position when the initial setting of the destination and the current vehicle position is completed, thereby displaying the straight distance on the display device 6. Further, the direction and distance of the vehicle are computed at intervals of unit time or unit run distance after the start of a vehicle run by using the output signals of a direction sensor 1 and a distance sensor 2 to calculate and display the destination, current position, and the ratio of the vehicle running speed and its destination directional component on the device. Thus, the vehicle reaches the destination securely in safety.

IPC: G02B6/122
Filed: 1988-04-30
Abstract: PURPOSE:To attain the recording with high recording density in excess of a limit of a conventional recording density by introducing a light to an optical guide path having a large difference in the refraction between a core and a clad. CONSTITUTION:A light emitted from a laser diode 4 is coupled with an optical guide core 6.
