Abstract: In a segment display type multi-color liquid crystal display device, the area of the display surface of the display device except the areas of segment electrodes is formed so as to present a color identical or similar to a color presented by the segment electrodes in an unselected state. Selected segments can be clearly recognized.

Abstract: An electronic odometer employing a non-volatile memory is used to indicate the total distance traveled by a vehicle such as an automobile. The total distance traveled by the vehicle, calculated by an arithmetic unit 3 from signals from a pulse generator 1, is written piece-by-piece sequentially into a non-volatile memory 7 which has N locations for storing the data on total distance. To read the data, the maximum value of the total distance data is found from the N locations storing total distance data of the non-volatile memory 7. When the difference between the maximum value and the data item written immediately before the maximum value is equal to a preset distance, the maximum value is indicated as the total distance traveled on digital display unit 8.

Abstract: An electromobile equipped with an automatic transmission which may detect a running condition of a vehicle and selects a gear ratio suited for the running condition. In this electromobile, a build-up characteristic of an electric motor current immediately after gear-change is improved, thereby minimizing delay in power transmission so as to shorten a gear-changing duration, in an attempt to improve an operational feeding of a driver at the time of gear change.
