Title: Air-fuel ratio control method for internal combustion engine
Inventor: NAKAJIMA TOYOHEI
IPC: F02D41/00
Filed: 1986-04-24
Abstract: PURPOSE:To enhance the responsiveness of air-fuel ratio control, by computing a proportional- plus-integral portion, an integral portion and a derivative portion in accordance with a deviation between an air-fuel ratio detected by an oxygen sensor which delivers an output signal proportional to the concentration of oxygen, and a desired air-fuel ratio. CONSTITUTION:An electronic control device 4 searches a map to determine a reference value for air-fuel ratio control in accordance with values detected by an absolute intake-air pressure sensor 32 and a crank angle sensor 32 after completion of engine warm-up which is indicated by an output signal from a water temperature sensor 33, and performs the feed-back control of an engine in accordance with the deviation between a value detected by an oxygen sensor 1 which generates an output signal proportional to the concentration of oxygen, and a desired value in order to obtain an air-fuel ratio in accordance with the operating condition of the engine. A correcting coefficient of air-fuel ratio feed-back control is calculated from a proportional control coefficient in accordance with the deviation from the desired value and the rotational speed of the engine, an integral control constant in accordance with the rotational speed and a derivative control coefficient in accordance with a subtracted value of the deviation between the previous value and the present value, which are read out from the map.

Title: Scanning type optical reader
Inventor: IIMA MITSUNORI
IPC: G06K7/10
Filed: 1987-04-22
Abstract: PURPOSE:To correctly further read code information by arranging a semiconductor laser so that the major axis direction with the large spreading angle of an injection laser beam can be the scanning direction of the object to be scanned. CONSTITUTION:A semiconductor laser 3 is arranged so that the major axis direction with a spreading angle K of an injection laser beam P can be a scanning direction X. Consequently, for the beam diameter of an injection laser beam P, the beam diameter of the scanning direction is largely stopped down by a projecting lens 4 and the injection laser beam P emitted through the projecting lens 4 shows an elliptic shape. It is preferable to arrange a rotation holding member 29 so that the direction, in which an elliptic major axis L extends, can pass through a rotation center O of the rotation holding member 29. Thus, the beam diameter at the beam waist is minimized as much as possible and the fluctuation of the beam diameter of the scanning direction due to the dispersion of the spreading angle can be suppressed.
