There is provided an air-fuel ratio control system for an internal combustion engine. The air-fuel ratio control system has an air-fuel ratio sensor arranged in an exhaust passage of the engine, which generates an output proportional to concentration of oxygen in exhaust gases emitted from the engine. The air-fuel ratio of a mixture supplied to the engine is controlled to a desired air-fuel ratio in response to the output from the air-fuel ratio sensor by the use of a proportional term and an integral term. A repetition period of inversion of the output from the air-fuel ratio sensor with respect to a predetermined reference value is calculated. Deterioration of the air-fuel ratio sensor is detected based the repetition period of inversion of the output from the air-fuel ratio sensor.
摘要:
A method of controlling air-fuel ratio of a mixture supplied to an internal combustion engine in a feedback manner responsive to an output signal from an exhaust gas concentration sensor. The air-fuel ratio of the mixture is controlled to a desired value by means of proportional control and integral control. The proportional control is inhibited, when the value of the output signal has changed from a lean side to a rich side with respect to a predetermined reference value while the engine is operating in one of a predetermined high load condition and a predetermined high rotational speed condition.

In the case where a lens unit where two ore more transparent resin lenses are combined is constituted, at least one transparent resin lens contains infrared absorbent. When the lens unit is assembled, an infrared laser is emitted to a joined portion between the transparent resin lens and the other transparent resin lens. As a result, the emitted infrared ray is absorbed by the infrared absorbent, so that the transparent resin lenses are welded to each other. An opaque lens barrel which holds the entire lens unit and the transparent resin lenses are joined by welding.

An endoscope of the invention includes: an LED for supplying illumination light to illuminate a subject; an image pickup device for picking up an image of a region to be inspected of the subject; a video display device provided with a monitor portion on which an endoscope image of the region to be inspected picked up by the image pickup device is displayed and an exterior member for holding the monitor portion; a power supply control circuit for supplying electric power to drive the LED and cause the LED to emit illumination light; and a heat radiation portion for radiating heat generated by the power supply control circuit formed on a rear surface opposing to a disposition surface of the exterior member on which the monitor portion of the video display device is provided.
摘要:
A slender insertion section of the endoscope has an endoscope distal-end portion, a tubular body and a bending portion, all extending along the longitudinal axis of the insertion section. The bending portion is arranged between the distal-end portion and the tubular body. The insertion section has an inner component. The bending portion has an annular ring assembly composed of a plurality of annular rings arranged side by side. Each annular ring has a ring body, a pair of bulging portion that face at one end face of the ring body, and a plurality of projections which the inner component can move. The most distal annular ring of the annular ring assembly supports one end of a wire. The wire passes through the annular rings and has its other end coupled to an operation section of the endoscope.
