Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To obtain a system for measuring relative digital voltage in which the variation of voltage curve can be detected as a function of time, while reducing the system cost, by measuring the connection time required for the capacitor voltage to reach a predetermined threshold level. SOLUTION: A voltage Vin to be measured is applied to the series circuit of a resistor R and a capacitor C. The joint of the resistor R and capacitor C is connected with the input of a threshold circuit TH. A switch SW is controlled by the output from a counter CNT to be opened at a periodic interval. When the switch SW is opened, charging cycle of the capacitor C is started. The switch SW is closed immediately after the voltage of capacitor C reaches the threshold level Vth of the circuit TH. When the closing time is counted by the counter CNT which delivered an output to a microprocessor mP where the reciprocal is calculated. The microprocessor mP delivers a digital data, which is in reverse proportion to the count of the counter CNT, to the output OUT.

Title: Method and device for reducing nitrogen oxide (nox) from combustion exhaust gas
Inventor: HAINTSU RAIDEITSUKU
IPC: B01D53/34
Filed: 1989-07-11
Abstract: PURPOSE: To decrease nitrogen oxides significantly by burning fuel stepwise in first stage to be decomposed thermally and then oxidizing the fuel between 800 deg.C-200 deg.C in second stage through catalytic reaction. CONSTITUTION: Combustion progress slowly at first by reducing oxygen supply to a reaction region through a combustion technology means while keeping the combustion temperature at 800 deg.C or below and prolonging the residence time.
