摘要： An evaporative fuel-processing system for an internal combustion engine includes an evaporative emission control system having a fuel tank, a canister, a passage extending from the canister to an intake passage of the engine, and a purge control valve arranged across the passage, and a pressurization device for pressurizing the interior of the evaporative emission control system. An ECU actuates the pressurization device to bring the evaporative emission control system into a positively pressurized state, after the purge control valve and an open-to-atmosphere control valve arranged across a passage connected to the canister are closed, and detects an amount of evaporative fuel generated in the fuel tank. The ECU determines whether or not a leakage occurs from the evaporative emission control system, based on a rate of variation in pressure within the evaporative emission control system, and a reference value which is determined based on the amount of evaporative fuel detected.

摘要： A misfire-detecting system for an internal combustion engine compares detected sparking voltage with a first predetermined comparative level and a second predetermined comparative level lower than the first predetermined comparative level. Whether a misfire has occurred in the engine is determined based upon a logical relationship between results of the comparisons. As a result, a misfire can be detected accurately even when dielectric breakdown of the mixture occurs while a misfire has occurred.

摘要： A fuel supply control system which controls an amount of fuel supplied to an internal combustion engine. An ECU detects a value related to an amount of combustion ions generated within cylinders. The detected value is compared with a predetermined value, and the amount of fuel supplied to the engine is corrected based upon the comparison result, when the engine is in a transient operating condition, such as acceleration and deceleration, whereby the responsiveness of the air-fuel ratio feedback control is enhanced to improve drivability and exhaust emission characteristics.

摘要： A catalyst deterioration-determining system determines deterioration of a catalyst arranged in the exhaust passage of an internal combustion engine. An ECU is responsive to an output from an O.sub.2 sensor arranged upstream of the catalyst or outputs from O.sub.2 sensors arranged upstream and downstream of the catalyst for controlling the air-fuel ratio of a mixture supplied to the engine by means of an air-fuel ratio correction value (first air-fuel ratio control). When the engine is in a predetermined operating condition, the system effects changeover from the first air-fuel ratio control to a second air-fuel ratio control which is responsive to the output from the downstream O.sub.2 sensor for controlling the air-fuel ratio of the mixture by means of the air-fuel ratio correction value. After the changeover has been effected, a time period is measured which elapses from the time the second air-fuel ratio control causes a change in the air-fuel ratio correction value from a richer side to a leaner side or vice versa with respect to a stoichiometric air-fuel ratio to the time the output from the downstream O.sub.2 sensor is inverted from the richer side to the leaner side or vice versa with respect to the stoichiometric air-fuel ratio. It is determined that the catalyst is deteriorated, when the measured time period is shorter than the predetermined time period.

摘要： A streamlined box girder type suspension bridge comprises a plurality of towers for supporting the cables, and the center main span and side spans comprising streamlined box girders suspended by a plurality of hangers from the cables. An additional mass of an appropriate weight comprising the material which would not directly contribute to the strength of the box girder is formed as a core at the predetermined portion of the box girder in order to suppress the bending-torsional flutter arising from the streamlined shape of the box girder, and the core extends over the complete span of the bridge symmetrically and with respect to the longitudinal axis thereof.

摘要： A metallic pressure vessel or container, made of a thin aluminum or aluminum alloy sheet coated with a resin suitably, used for a small size beer container. The vessel is composed of (a) a main body member of bottomed cylindrical form, with a bulge in the central part thereof precessed by a novel method, provided with at least three protrusions and recessed beads disposed therebetween alternately, for stable setting and reinforcing, and (b) a lid member, for covering the former body, which is made into an inverted bowl shape, with a mouth portion integrally formed for being crowned thereon, and provided with a plurality of small wave like patterns consisting of continuous and smooth hills and valleys. Those two parts are generally made by multiple deep-drawing processes and joined together by the double seaming method. The process of the mouth portion making is characteristic in its burling and curling processes.
