Abstract: The optical apparatus includes an image pickup optical system including a focus lens, a controller controlling movement of the focus lens in an optical axis direction of the image pickup optical system, a shake detector detecting a shake amount of the optical apparatus in the optical axis direction, and a memory storing plural shake amounts sequentially detected by the shake detector. The controller calculates, in response to a start instruction of exposure for the image pickup and before start of the exposure, a predictive value of the shake amount for a time point of the exposure based on the plural shake amounts stored in the memory and including at least one shake amount detected after the start instruction of exposure. The controller moves the focus lens to a position corresponding to the predictive value before the start of the exposure.

Abstract: A step height is provided in an upper surface of a nozzle plate. Plural pairs of nozzle holes are provided in the nozzle plate, and thereby a liquid film is formed with fuel liquid columns injected from each pair of nozzle holes. In one nozzle hole, as the step height is placed in the vicinity of the nozzle hole, the direction of the fuel flow is changed to a direction along the surface of the step height, and a swirl flow is formed at its inlet. On the other hand, as the other nozzle hole is away from the step height, thereby a uniform inflow without swirl flow is formed. As a result, the shape of the liquid film is changed to a predetermined pattern liquid film by increase of the pressure.

Abstract: An optical apparatus is disclosed which can prevent displacement of subject images due to an initializing operation of the image stabilizing unit from being seen by a photographer through a finder. The apparatus comprises an image-stabilizing unit which includes a movable unit movable for image stabilization and balls movable in conjunction with the movement of the movable unit, and a controller which controls operations of the movable unit. The controller causes the movable unit to perform a specific operation for moving the balls to a specific position in response to mounting of the optical apparatus on another optical apparatus, the specific operation being a different operation from an image stabilization operation of the image-stabilizing unit.

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.

Abstract: A vehicle with an air conditioner comprises an instrument panel center member disposed vertically behind an evaporator and fixed to a vehicle structure. The evaporator is disposed obliquely in such a manner that its maximum-area face has a crossing angle relative to a horizontal face and a distance between its front and rear ends is a specified length or greater. The evaporator is configured so as to be rotated between a vehicle dash panel being moved rearward and the instrument panel center member at a frontal crash of a vehicle in such a manner that the distance between its front end and rear end becomes shorter. Accordingly, the evaporator can be prevented from being pushed into a vehicle cabin at the vehicle frontal crash, thereby ensuring the safety of the passenger.

The control circuit changes the image stabilizing drive control characteristic of the drive circuit to compensate for changes in viscosity of the viscous damper with temperature.

Abstract: 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.

Abstract: An image-taking apparatus is disclosed which allows a selection of a type of image stabilization to be used from optical image stabilization and electronic image stabilization as required to provide an excellent output image. The image-taking apparatus has an image generator which is operable in a first mode in which it performs electronic image stabilization processing based on a plurality of images sequentially taken with an image-pickup device to generate an output image and a second mode in which it generates an output image without performing the electronic image stabilization processing on an image taken with the image-pickup device. The image-taking apparatus also has a controller which causes image stabilization operation to be performed through driving of an optical system in both of the first and second modes and selects one of the first mode and the second mode.
