Title: Notifying system for function regulation service
Inventor: AKAGI KATSU
IPC: H04M3/42
Filed: 1988-08-15
Abstract: PURPOSE:To transfer the function regulation of an exchange to an extension by using the function of the exchange through a voice accumulator while the extension is connected to the voice accumulator, and notifying regulation information from the exchange during the regulation. CONSTITUTION:An extension A, which is connected through a call switch SW of the exchange to a voice accumulator VMM, dials a special number. When the voice accumulator VMM judges that the received special number is the function to be realized by the exchange, it transmits extension information connected through a route B to the special number information to a central processor CC of the exchange. The exchange recognizes the function, which is realized by the special number information transmitted by the voice accumulator VMM, and when the function recognized by the extension information is the impossible function, the regulation information is transmitted to the voice accumulator VMM. By the regulation information received by the voice accumulator VMM, the fact that the function is regulated by a voice is transmitted by the extension A.

IPC: F02M25/08
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To speedily increase purge quantity to a required quantity while restraining air-fuel ratio fluctuation when purge is started. SOLUTION: In gradually increasing a purge rate when supply of evaportive fuel is started, purge quantity is increased synchronously with reversion of output of an air-fuel ratio sensor for feedback of an air-fuel ratio in an initial stage of a gradually increasing period, and purge quantity is increased synchronously with time in the final period of the gradually increasing period. In the initial stage of supply of evaporative fuel, the purge rate is increased by 1%, for example, every time output of an air-fuel ratio sensor is reversed from lean to rich, so it is gradually and slowly increased. As a counter C is subtracted to zero, the purge rate is increased by 0.1%, for example, for every specified time, so it is gradually and speedily increased to a target purge rate.  Otherwise, the purge quantity may be gradually increased synchronously with time in the whole gradually increasing period, where time intervals may be set different between the initial period and in the final period.

The address from the counter 48 is supplied to the RAM16, and the relation between the timewise position at which a horizontal synchronizing signal arrives, and the timewise position which switches the condition of writing and reading of the RAM16, is controlled constantly. In this way, generation of picture color dislocation can be prevented.
