Title: Navigation device
Inventor: TSUDA SHINGO
IPC: G01C21/00
Filed: 1994-05-09
Abstract: PURPOSE:To enable a navigation device to accurately give parking zone information to the operator of the device when necessary. CONSTITUTION:When a parking zone retrieving key is pressed (S30), whether or not parking zone information has been inputted, is checked (S31). When the information has been inputted, the distance to each parking zone from the present location of its own vehicle is found from the coordinates of the present location and those of each parking zone (S32). Then, the informing order of the parking zone information is decided in accordance with the found distances and the degree of congestion in each parking zone obtained from the inputted parking zone information (S33). When the informing order is decided, the information is displayed on a screen in the decided order and, at the same time, the information is outputted in voices (S34). Therefore, the driver of the vehicle can smoothly park the vehicle in a vacant parking zone near the present location, because he can obtain accurate parking zone information when he requires it.

Abstract: PURPOSE:To obtain a simple and convenient structure wherein a specimen cna be set very easily, by sensing the thickness of the dielectric film to be grown on a member having a reflecting surface as the magnitude of the terminal voltage of a semiconductor laser element. CONSTITUTION:A self-combining type semiconductor laser 10 is constituted by the semiconductor laser element 7, a lens 8 for forming parallel beams, and a plane mirror 9 facing the beams at a right angle and having a suitable reflectivity. The dielectric film 2 is formed on the plane mirror 9. The light irradiated from the semiconductor element 7 is reflected by the plane mirror 9, and returned to the light emitting part of the semiconductor laser element 7. The optical density in th active regiob in the semiconductor laser element 7 is varied, and the terminal voltage of the semiconductor laser element 7 is also varied. Therefore the variation in the reflectivity of the plane mirror 9 is sensed as the variation in the terminal voltage of the semiconductor laser element 7. Since the reflectivity of the plane mirror 9 varies with the thcikness of the dielectric film 2, the thickness of the dielectric film 2 can be monitored.
