Title: Output error compensating circuit for digital-to-analog converter
Inventor: ISHIKAWA TOMOHISA
IPC: H03M1/06
Filed: 1980-04-15
Abstract: PURPOSE:To realize a compensation for the conversion output error, by extracting the digital signal when the D/A conversion output shows the discontinuity and then adding and subtracting this digital signal to/from the analog signal. CONSTITUTION:The bit output of the digital signal output device 11 is supplied to the switching circuit 12. The circuit 12 switches selectively the reference level Vref and the earth level in correspondence to the digital input. The resistance of the ladder resistance circuit 13 is connected in correspondence to each bit output of the circuit 12, and this output is applied to the operational amplifier 14. On the other hand, the most significant bit MSB of the device 11 is applied to both ends of the variable resistance 20 via the buffer 18 and inverter 19. The DC component of the output of the resistance 20 is eliminated by the capacitor 20, and the output of the resistance 20 is applied to the minus terminal of the operational amplifier 16 to be added or subtracted to/from the output of the amplifier 14. In such way, the discontinuity can be compensated for the analog output of a D/A converter.

Abstract: PROBLEM TO BE SOLVED: To efficiently purify exhaust gas by supplying a reducing agent when an exhaust gas temperature passes the catalytic activity start temperature during temperature rising, and designated standby time elapses, and timely stopping the supply of the reducing agent when the exhaust gas temperature passes the catalyst activity start temperature during temperature drop. SOLUTION: During the operation of an engine 1, when the supply of a reducing agent is controlled by a control device 7, an exhaust gas temperature Tg detected by a temperature sensor 6 is read. Secondly, whether the reducing agent is at present supplied or not is determined, and if NO, it is determined whether the exhaust gas temperature Tg becomes larger than the catalytic activity start temperature Tcat at which the catalyst is activated or not. If YES, when designated start standby time t1 elapses, the reducing agent is supplied from a reducing agent supply device 4 to the exhaust system. On the other hand, in the case where it is in the supply region of the reducing agent, when Tg<Tcat, after the lapse of designated stop standby time, a stop command is given to the reducing agent supply device 4 to stop the supply of the reducing agent to the exhaust system.
