摘要： A system for purifying exhaust gas of an internal combustion engine having a NOx reduction catalyst (NOx absorber) installed in the exhaust system of the engine which absorbs NOx in the exhaust gas generated by the engine in a lean environment where a lean fuel mixture is supplied and desorbs to reduce the absorbed NOx in a rich environment where a rich mixture is supplied. In the system, the rich fuel mixture is supplied for a period immediately before cutoff. With the arrangement, the NOx reduction catalyst desorbs the absorbed NOx and is regenerated to absorb NOx sufficiently. At the same time, the NOx reduction catalyst is regenerated from sulfur poisoning, thereby preventing the NOx purification efficiency from being degraded.

摘要： A laser-diode driving circuit that ensures that the optical output of a laser diode will be stable within a wide temperature range. This circuit includes a reference voltage generator for generating a reference voltage, a control voltage generator for generating a control voltage, an amplifier for producing an amplified output signal corresponding to the difference between the reference voltage and the control voltage, and a driving current generator for generating a driving or operating current for driving a laser diode. The driving current generator is driven by the amplified output signal. The control voltage has a temperature dependence approximately the same as that required for keeping an optical output of the laser diode at a specified level independent of the ambient temperature change. Preferably, the control voltage generator contains a p-n junction diode for producing a temperature-dependent voltage, and a thermistor for compensating the temperature-dependent voltage to thereby produce said control voltage having an exponential characteristic with respect to the ambient temperature.
