    摘要: A method is provided for purifying exhaust gas from an engine having an exhaust passage with a selective reducing catalyst and an oxidation catalyst upstream of the selective reducing catalyst. The method calculates an amount of NOx that flows into the selective reducing catalyst; sets an amount of an additive agent to be supplied to the selective reducing catalyst based on the calculated amount of NOx; determines a degradation degree of the oxidation catalyst; determines whether a correction to the amount of the additive agent is necessary based on the determined degradation degree of the oxidation catalyst; corrects the amount of the additive agent to be supplied when the correction is necessary; and supplies the additive agent to the selective reducing catalyst in the corrected amount if the amount is determined to be corrected and in the uncorrected amount if the amount is determined not to be corrected.

    摘要: A focal plane shutter has at least one shutter blade group comprised of a leading blade and a set of trailing blades. A first parallel link mechanism is pivotally connected at two spaced locations to the leading blade to effect displacement of the leading blade relative to a shutter opening. A second parallel link mechanism is pivotally connected at two or more spaced locations to the set of trailing blades to effect displacement of the trailing blades relative to the shutter opening. The distance between the two pivotal connections of the first parallel link mechanism is greater than the distance between the at least two pivotal connections of the second parallel link mechanism.

    摘要: A method of driving a motor-driven shutter for a camera having a sector opening lever which is pivotal to open and close sectors, a sector opening cam movably supported and engageable with an engagement pin provided on the sector opening lever, an actuating member for pivoting the sector opening lever through engagement between the sector opening cam and the engagement pin, and a reversible motor for driving the actuating member. The motor is temporarily suspended when the actuating member is driven to a position where the sector opening cam comes into contact with the engagement pin, and the motor is restarted to cause the engagement pin to reach a predetermined position on the sector opening cam. Thus, it is possible to obtain a stable shutter opening operation and hence increase the degree of aperture accuracy.
