Title: Method of controlling air-fuel ratio of internal- combustion engine
Inventor: TANAKA SEIGO
IPC: F02D41/14
Filed: 1983-08-16
Abstract: PURPOSE:To precisely control the air-fuel ratio irrespective of deterioration of an input sensor, by correcting the integration time-constant of a feed-back control system when the temperature of a catalyst reactor disposed in the exhaust system is raised above a designed temperature, so that the control center of the air-fuel ratio is shifted to the lean side. CONSTITUTION:In the case of that a CPU3 changes over the inclination (integration time-constant) of the correcting coefficient of fuel injection amount in accordance with an input sensor whose output is an electrical voltage V dependent upon the O2 concentration in exhaust gas to control a fuel injection valve, a switch SW is closed when a stability detecting section 31 detects the stable engine condition from an engine condition indicating signal S. Therefore, the output of a comparating section 32 for comparing a designed temperature T0 stored in a designed temperature T0 storing section 34 in a catalyst reactor with a detected temperature T stored in a storing section 35 for storing the output of a temperature detecting element in the catalyst reactor, is delivered to an integration time constant correcting section 33. Then, if T>T0, the integration time constant is made large so that the control center of the air-fuel ratio is shifted to the lean side.

Title: Polygonal line extending circuit
Inventor: OKAMOTO HIROO
IPC: H03M7/50
Filed: 1982-08-30
Abstract: PURPOSE:To reduce the generation of distortion produced with nonlinearity without deterioration of linearity of an input/output characteristic, by expanding data at a data expanding circuit and correcting the expanded data at a data correcting circuit. CONSTITUTION:The data expansion circuit 43 expands data and the expanded data is correctd at the data correcting circuit 46. The input/output characteristics are improved by inserting the corrected data to a lower bit after expansion according to each range. The error to the data before compression is halved in comparison with conventinal methods with the data correction above, and the input/output characteristics are shown in 39. Thus, the input/output characteristics in neglecting the quantized noise are linear equal to the case with broken line 1 of linear PCM, allowing to prevent the production of distortion because of the nonlinearity of the input/output characteristics.
