    摘要： A camera which maintains accuracy of stop position in accordance with the state of an image-taking optical system and allows driving of a focus lens to a target position in a short time period, is disclosed. The camera comprises a motor which drives the focusing lens, and a controller which controls the motor such that the focusing lens is stopped at the target position by performing deceleration control in accordance with a predetermined deceleration control pattern. The controller changes the deceleration control pattern in accordance with the state of the image-taking optical system detected by the state detector.

    摘要： An apparatus for producing a metallic ribbon includes a cooling roll, a melt nozzle, and an air-cutoff unit provided to cover at least a portion of the periphery of the cooling roll and at least the melt blowout end of the melt nozzle, for preventing an inflow of air due to rotation of the cooing roll. The air-cutoff unit has a roll top air-cutoff plate provided above the cooling roll to extent from the front side to the rear side in the rotation direction of the cooling roll in such a manner that it approaches the cooling surface in the direction opposite to the rotation direction of the cooling roll. The melt blowout end of the melt nozzle is arranged to pass through a nozzle mounting hole provided in the roll top air-cutoff plate and face the cooling surface of the cooling roll.
