Title: Air-fuel ratio control device for internal combustion engine having exhaust reflux device
Inventor: TAKAHASHI HIDEAKI
IPC: F02D41/14
Filed: 1994-04-12
Abstract: PURPOSE:To accurately control exhaust in the vicinity a target air-fuel ratio and sufficiently purify it at the time of exhaust reflux. CONSTITUTION:When an air-fuel ratio is shifted from a rich condition to a lean condition, an NOx correction rate FPL for correcting difference of a target air-fuel ratio control point is calculated (S20) based on an NOx density FNO obtained in S17. Renewal is conducted by the use of a value obtained by adding a proportional rate PL in an alpha increasing direction to the FPL (S21). When the air-fuel ratio is shifted from the lean condition to the rich condition, the correction rate is calculated (S22) based on the NOx density FNO. Renewal is conducted by the use of a value obtained by subtracting the proportional rate PR in an alpha decreasing direction from the FPR.

Title: Method for desilvering photographic processing solution and photographic processing machine
Inventor: AOKI SHOZO
IPC: G03D3/00
Filed: 1985-04-08
Abstract: PURPOSE:To efficiently recover silver without causing fogging by using bed electrodes as the cathode and anode in an electrolytic cell. CONSTITUTION:When a photographic processing soln. for a silver halide photographic material contg. silver complex ions is desilvered by electrolytic treatment, bed electrodes are placed as the cathode and anode in an electrolytic cell. The effective potential distribution in the bed electrodes is <=300mV, especially <=100mV. As the surface tension of the processing soln. is made lower, a more significant effect is produced, and even in case of continuous treatment, the concn. of silver complex ions at the outlet of the electrolytic cell can be remarkably lowered. The processing soln. flows in the electrolytic cell I from the bottom and passes through the cathode 6 and fluidized granules 5 having cathode effect. Silver is recovered from the soln., and at the same time, a product is formed by reduction. The product is returned to Fe (III) by oxidation with the anode 3 and fluidized granules 2 having anode effect. Thus, silver can be efficiently recovered without sticking spotlike foreign matter or causing fogging or stain.
