Abstract: PROBLEM TO BE SOLVED: To realize an automobile navigation system never giving any unnecessary fear to a driver by preventing that a deviation judgment is too late to turn at an intersection in the traveling out of a recommended route or the judgment is wrong by the temporary deterioration of position detecting precision. SOLUTION: In the judgment of whether a vehicle deviated from a recommended route or not, the road kind of the traveling road is judged (steps S10, S11), and a deviation judgment distance DD that is a threshold for judging whether the vehicle is deviated from the recommended route or not is changed according to the judgment result of the road kind (steps S12, S13, S14). According to this, since the deviation judgment distance DD is changed between the traveling on a road with a short intersection-to-intersection distance as a city road or narrow street and the traveling on a road with a long intersection-to- intersection distance as a highway or mountain road, the deviation judgment can be regularly performed by use of a proper threshold.

Title: Method for separation and recovery of carbon monoxide
Inventor: FUJITANI SHOGO
IPC: C01B32/40
Filed: 1993-09-03
Abstract: PURPOSE:To provide a method to separate and recover carbon monoxide gas from mixture gas at a high yield with a low cost for facilities. CONSTITUTION:Carbon monoxide is separated and recovered by using a pressure swing adsorption method. In this method, the pressure in the adsorption tower after the adsorption process is completed is released under such conditions that the pressure is lower than the partial pressure of carbon monoxide in the source material, the amt. of gas released is under 50% of the gas amt. adsorpted, and the pressure after release is the same or higher than atmospheric pressure. Thus, impurities remaining in the tower is purged out with the gas through the exit of the adsorption column. After releasing pressure, the product gas is partly introduced to the tower to completely remove impurities in the tower. The gas perged with the product gas is introduced to another adsorption column to increase the pressure in the adsorption tower while carbon monoxide in the purged gas is adsorbed in this adsorption column. After completing purging, the column is evacuated into vacuum to recover carbon monoxide adsorbed to the adsorbent.
