Patent JP-H01277008-A (JP)
Title: Oscillation circuit
Inventor: NEMOTO NOBUYUKI
IPC: H03B5/12
Filed: 1988-04-28
Abstract: PURPOSE:To maintain stable oscillating operation by adding grounded base transistors to the collector sides of a pair of grounded emitter differential transistors which constitute a differential amplifier circuit. CONSTITUTION:Grounded base bipolar TR Q1 and Q2 are interposed respectively in the collector sides of grounded emitter bipolar transistors TR Q3 and Q4 which constitute the differential amplifying circuit. The bases of the TR Q1 and Q2 are biased in common by a bias power source VB. By the oscillation circuit constructed like this, TR Q1 and Q3 and TR Q2 and Q4 respectively constitute cascode circuits. Consequently, the internal feedback capacity of the differential amplifying circuit can be limited sufficiently small and the stable oscillating operation can be maintained at an ultra high frequency.

Title: Low-nox combustion system
Inventor: MORITA SHIGEKI
IPC: F23C99/00
Filed: 1985-05-21
Abstract: PURPOSE:To reduce NOx to harmless N2 by a method in which the lowest burner among burners set on the upper and lower parts of the grating of a combustor is taken as the burner where fuel is excessively supplied and nitrogenous compounds generated from the burner are used as reducing agents. CONSTITUTION:Plural burners are vertically set in the grating 1 of a boiler as a combustor, and a reducing burner 4 is set at the lower part of the upper three- stage burners as the main burner. On the upper furnace wall of these burners, an NO boat 2 is formed where two-stage combustion is made. In the reducing burner 4, the air ratio is set to 0.7 or less, that is where a strongly reducing combustion is made under an extremely excessive fuel supply condition with an average 17% or less oxygen concentration in all air amount to be supplied. Since highly reductive intermediate products are formed by nitrogen in fuels, NOx in the combustion gas of the main burner can be reduced to N2.

Abstract: PURPOSE:To reduce the distribution of air-fuel ratio by determining the correction coefficient of the limit value compared with the fundamental fuel injection pulse width according to the acceleration and deceleration state, when the fuel injection pulse width is limited according to the value due to the processing of the fundamental fuel injection pulse width. CONSTITUTION:When an engine 1 is in operation, the fundamental fuel injection amount (injection time width) W is calculated in a control circuit 20 on the basis of the outputs of an air amount sensor 8 and a revolution speed sensor 11. Then, the weighted average procesing value T is obtained on the basis of the fundamental injection amount W, and the both values W and T are compared. When W>T or W<T, the relation of W>T' or W<T' (T' is a prescribed limit value) is judged, and when the judgement is YES, the above-described limit value is outputted as the fundamental injection amount Wi. Then, the fundamental injection amount Wi is corrected accoring to the correction amount K determined according to the output of a water-temperature sensor 10, and fuel injection valves 51-56 are controlled according to the corrected fuel injection amount.
