An elastically coupled joint comprises a shaft for transmitting rotary motion, a housing in which the shaft is concentrically inserted, an elastic member provided between the shaft and the housing, and a stopper for preventing excessive displacement between the shaft and the housing. The housing is provided, at an end thereof with a yoke for supporting a spider of a universal joint. The elastic member is provided with a tubular outer ring and a cylindrical elastic body fixed on the inner side of the outer ring. The shaft is pressure fitted into the central portion of the elastic member. The stopper is composed of a pin member inserted in a penetrating hole formed in the housing, the elastic member and the shaft. The penetrating hole may be formed such that the stopper pin is received in the shaft with a press fit, with each end portion of the pin having a predetermined uniform circumferential gap to the housing and the outer ring.

Control device of an internal combustion engine that determines whether or not to perform sensor element heating control of an air-fuel ratio sensor with high accuracy based on the mass of condensed water in an exhaust pipe. The control device computes the rate of change of condensed water mass in an exhaust pipe based on the saturated water vapor pressure and the water vapor partial pressure of exhaust gas, and computes the rate of change of evaporation mass in the exhaust pipe based on the amount of heat which the condensed water receives in the exhaust pipe. The control device updates the mass of condensed water based on the rate of change of condensed water mass and the rate of change of evaporation mass, and determines whether or not to perform heating control by a heating controlling unit based on the updated mass of condensed water.

The invention precisely achieves an air fuel ratio control precision in each of operating regions of an engine, particularly a demand air fuel ratio at a time of an engine transition. In a fuel control system correcting a basic fuel amount in such a manner as to estimate a fuel adhered to an air intake pipe of an engine and an evaporated fuel from the adhered fuel so as to achieve a demanded air fuel ratio, a temperature of a fuel adhered portion is estimated on the basis of an amount relation between the fuel to be adhered and the already adhered fuel, or a heat quantity balance. A fuel adhesion amount and a fuel evaporation amount are determined on the basis of the estimated temperature.

At the start-up of an engine, the ignition timing and the air-fuel ratio are controlled to prevent overload onto the volume of ISC air and decreased torque and torque difference.The fuel condition based on the amount of ignition timing correction to inhibit rotational fluctuation during idling is determined and the fuel quantity based on the result is corrected.Right after an engine has started and until a pilot burner is created in the heat spot of the catalyst, the ignition retard control is mainly executed, and at the time when it is determined that a pilot burner has been created in the catalyst's heat spot, the lean air-fuel ratio control is to be executed instead of the ignition retard control. Furthermore, when the ignition retard control changes to the lean air-fuel ratio control, the state transition control is executed along the equivalent ISC air volume line so as not to cause torque fluctuation.

This vehicle travel safety device improves the recognition accuracy of road shapes while preventing an extreme increase in the computation amount required for correction of road data. An inactive determination portion determines that the operating portion is inactive when a safety device does not operate for an estimated curve that is estimated by a curve estimating portion and also deceleration of a predetermined amount or more occurs by a deceleration operation of the driver before entering the estimated curve or while traveling through it, or when a safety device does not operate for an estimated curve that is estimated by a road shape estimating portion and also the vehicle condition of the self-vehicle is not in the proper vehicle condition to be able to properly pass the estimated curve. The data correcting portion changes the road data of the storage portion that is used in the detection of the recognized curve shape that corresponds to this estimated curve so as to facilitate operation of the operating portion at the estimated curve where the operating portion is determined to be inactive by the inactive determination portion, or adds new road data to the storage portion.

Disclosed is an image processing device capable of recognizing a specific image such as an image which is prohibited from printing at high speed and, moreover, without being influenced by an image forming process. A drawing command analysis unit analyzes a drawing command received by a drawing command input unit and sends an analysis result to both an output image data generation unit and a recognition image data generation unit. The output image data generation unit generates output image data adapted to an image formation device in accordance with the drawing command. In parallel with the operation, the recognition image data generation unit generates recognition image data adapted to a recognition unit in accordance with the drawing command. The recognition unit performs a process of recognizing a specific image by using the recognition image data. The recognition image data may have a data format, resolution, a color space, and the number of bits per pixel which are different from those of the output image data. When the specific image is recognized by the recognition unit, the output image data generation unit stops outputting the output image data.
