Filed: 2000-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a method of controlling the air/fuel ratio of an internal combustion engine to set the air/fuel ratio securely inside a purification window and keep the purification rate of exhaust gas excellently. SOLUTION: The internal combustion engine has an air/fuel ratio actuator for changing the air/fuel ratio, a three-way catalyst, and an upstream oxygen sensor in the exhaust pathway on the upstream side of the three-way catalyst. A first operation position of the air/fuel ratio actuator with a first air/fuel ratio, with which the threeway catalyst can excellently purify CO, HC and NOx in the exhaust gas at the same time, is previously stored in a memory means, and in addition, a second operation position of the air/fuel ratio actuator with a second air/fuel ratio, with which the upstream oxygen sensor can detect the variation of the air/fuel ratio, is previously stored in the memory means.  Then, the internal combustion engine repeats alternately the operation with the air/fuel ratio actuator at the first operation position for a prescribed period of time and the operation for the shortest period of time necessary for the upstream oxygen sensor at the second operation position to detect the variation of the air/fuel ratio.

Title: Electronic ticket, electronic lift ticket, electronic climbing ticket, electronic ticket return accepting device, and self-position detection device
Inventor: TANAKA KOICHI
IPC: G07B15/00
Filed: 2000-09-27
Abstract: PROBLEM TO BE SOLVED: To provide an electronic lift ticket capable of developing the merit of a GPS function for acquiring a self-position. SOLUTION: A skier obtains an electronic ticket by paying a deposit. The electronic lift ticket acquires a self-position (S101), and records the sliding route of the skier (S102). By a comparison between the sliding route and a pre-stored course, the lift ticket judges whether the skier slides in or out of a course (S103). When the skier slides out of the course, the lift ticket records a distance and a time for sliding out of the course (S104). Based on the distance and time for sliding out of the course, the lift ticket calculates '-α' as a reduced amount (S105). Based on the reduced amount '-α' and a refund amount data D, the lift ticket calculates 'D=D-α', and updates the value of the refund data D (S106).  After the sliding is completed, the skier returns the electronic lift ticket to an electronic lift ticket return accepting device, and receives the refund of the amount indicated by the refund amount data D.
