Abstract: PROBLEM TO BE SOLVED: To eliminate the need of plural time telephone number registration by making a master unit and a slave unit respectively and successively compare the contents of the telephone books of each other and performing control so as to delete the data when the same data as a communicating party are present in the telephone book and add them when they are not present. SOLUTION: When the data for one item are transferred from the master unit 7 to the slave unit 18, the slave unit 18 checks a field and confirms whether or not they are the data whose transfer is permitted. In the case that the transfer is not permitted, the transmission request of the next data is outputted to the master unit 7. When they are the data whose transfer is permitted, they are successively compared with telephone numbers recorded in the telephone book of the slave unit 18, and when the same telephone number is present, the entire item is delete and the next data are requested to the master unit 7. When the pertinent telephone number is not present, it is additionally registered to the telephone book of the slave unit 18.  In such a manner, the data present in the telephone book of the master unit 7 but not present in the telephone book of the slave unit 18 are additionally registered to the telephone book of the slave unit 18.

Since a low air flow rate q' through an opening 21b is also increased, a differential pressure is changed in proportion to the flow rate Q, and an air-fuel ratio is controlled to a specified value.
