A method for fabricating a capacitor includes forming an isolation layer over a substrate. The isolation layer forms a plurality of open regions. Storage nodes are formed on surfaces of the open regions. An upper portion of the isolation layer is etched to expose upper outer walls of the storage nodes. A sacrificial layer is formed over the isolation layer to enclose the upper outer walls of the storage nodes. The isolation layer and the sacrificial layer are then removed.

An SMA actuation apparatus comprises a camera lens element supported on a support structure by a plurality of flexures. An SMA wire at an acute angle to the movement axis and a biasing element are connected between the support structure and the movable element. A component of the force applied by the SMA wire perpendicular to the movement axis compresses the flexures causing them to apply a force to the movable element having a component along the movement axis in the same direction as the SMA wire. An end-stop limits the movement of the movable element, and the moment applied by the end-stop to the movable element about the center of stiffness is equal to the moment applied by the SMA wire about the center of stiffness at the point when the movable element loses contact with the end-stop on contraction of the SMA wire.

An input device has a housing having an operation hole formed therein, an operation member supported in a slidably moving manner in multi-directions within the operation hole, and at least two magnetic sensors, arranged at a periphery of the operation member, for detecting change in magnetic property by displacement of the operation member. The operation member includes a holder having a circular ring-shaped magnet incorporated in a fit-in hole and a central push button having a disc plate made of magnetic material integrated at a lower surface. The central push button is fitted in the circular ring-shaped magnet to adsorb, in a separable manner, the disc plate to the circular ring-shaped magnet and position-regulate the central push button.

In an axial fan, a case (40) accommodating the fan motor stator (50) is anchored into a bearing retainer (10), in which ball bearings (20, 21) as a bearing unit are accommodated, along a bulge part (13) formed on the lower end portion thereof. The case (40) extends heading axially downward, wherein there is no diametrical overlap between the ball bearings (20, 21) and the stator (50). Since only the bulge part (13) of the bearing retainer (10) is fixed to the case (40), heat arising from the stator (50) is thermally conveyed via the case (40) only to the bulge part (13). The fact that the thermal conveyance zone is minimal enables unrestrained curtailment of heat transmitted to the ball bearings (20, 21). As a result the axial fan can be designed for prolonged bearing lifespan.

A method of adjusting a pedestal includes analyzing the reflected light and leveling the pedestal, translating the pedestal, calibrating the pedestal height to a preheat ring level, and checking the level and location of the pedestal in response to the analyzed reflected light.

An object lens driving device is disclosed that has a small tilt even when focusing and tracking operations are performed at the same time. A movable unit including an object lens holding member with an object lens, focus coils and track coils attached thereon is supported by two sets of four wire springs, totaling eight wire springs, connected to fixed units on two sides of the object lens holding member in the tangential direction. When the movable unit is set to face a driving magnet which has a boundary line at the center portion of the magnet and parallel to the focusing direction, and boundary lines at two ends of the magnet and parallel to the tracking direction, the interval Lc_Fo between centers of the focus coils in the tracking direction is less than the interval Lm_Fo between centers of magnetic flux density distributions of the magnet. Consequently, a moment is generated to cancel out a tilt of the movable unit occurring in a supporting system when the movable unit moves in the focusing direction and the tracking direction.
