Abstract: A multilayer coating film is provided on one side of a transparent or semitransparent glass plate to afford a golden appearance to the coated glass plate at least when viewed from the uncoated side. Essentially the multilayer coating film is made up of a TiN layer adjacent to the glass plate surface and either a Ti layer or a Cr layer which overlies the TiN layer, and the coating film is formed such that the transmittance of the coated glass plate for visible light becomes not more than 40%. Optionally, the Ti or Cr layer is overlaid with either a TiO.sub.2 film or a Cr.sub.2 O.sub.3 film. Also optionally, either a TiO.sub.2 film or a Cr.sub.2 O.sub.3 film is interposed between the TiN layer and the glass plate surface. Each layer of the multilayer coating film can be formed by sputter deposition using a relatively simple method, an the multilayer coating has good durability.

Abstract: A method of recording the travel locus data for an on-board navigation system for motor vehicles stores, at the time of storing data of each location of roads in maps in numberical form, index numbers, which are allotted in sequence to particular locations on the road for each road, together with map numbers each of which is allotted to each map and path numbers each of which is allotted to each road within each map. When the vehicle is running, the map number and the path number are monitored while the present location of the the vehicle is being recognized, and a previous map number, a previous path number and a previous index number are memorized if the present map number is different from the previous map number or the present path number is different from the previous path number. Distinctive point numbers which are allotted to particular locations on the road are also used instead of the path numbers and index numbers. Thus, the amount of data in memorizing the travel locus data is considerably reduced.
