摘要： A lens-interchangeable camera includes a focus detector performing focus detection and a controller performing a drive control of a lens based on a defocus amount. The controller finishes focusing operation without driving the lens when the defocus amount is out a range of a first in-focus determination width, and performs the focusing operation when the defocus amount is out a range of the first in-focus determination width. The controller finishes the focusing operation without performing the focus detection again after completing the drive when the defocus amount is out a range of a second in-focus determination width, and performs the focus detection again after completing the drive when the defocus amount is out a range of the second in-focus determination width. The second in-focus determination width is set to be greater than the first in-focus determination width and be greater than or equal to a drive limit value.

摘要： In a magnetic disk device including a magnetic disk coated with a lubricant, a face of a magnetic head slider, at a trailing side of the slider, is constructed so that all or part of an outer region adjoining other faces is made less wettable than other regions present at the trailing side face. For example, the trailing side face 13 of the magnetic head slider 8 has a protrusion 12 at both upper and lower ends of the face 13. Surface wettability of a face 12a forming the top of one of the protrusions 12 is reduced below surface wettability of other regions (a face 12c orthogonal to the face 12a, and a region 11). In addition, the other regions each have surface wettability that allows any sticking droplets of the lubricant to provide a sufficient wetting spread, but to such an extent that the droplets do not fall.This prevents a wetting spread of the lubricant to an air bearing surface, and hence, a fall of the lubricant from the magnetic head slider. Reliability is therefore enhanced.

摘要： The image-pickup apparatus includes a controller that controls the energization of the actuator for driving the aperture stop. The controller receives from a lens apparatus information on a time period for controlling the energization of the actuator, the information being set corresponding to the type of the actuator. During an image-pickup period in a state in which the aperture stop has been driven to a target aperture position, the controller outputs to the lens apparatus an instruction for stopping the energization of the actuator or reducing the energization amount thereof in response to the elapse of the time period. This can reduce power consumption.
