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.

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.

This disclosure relates to a data storage medium, and in particular to a data storage medium comprising at least one high modulus layer used to control the overall degree of flatness in the storage medium.

A pedestal positioning assembly system for use in a substrate processing system includes a pedestal rigidly attached to a pedestal shaft, a reference rigidly attached to the substrate processing system, a lateral adjustment assembly to adjust a lateral location of the pedestal relative to the reference, and a vertical adjustment assembly to adjust a tilt of the pedestal relative to the reference. The lateral adjustment assembly and the vertical adjustment assembly are external to a processing chamber and are coupled to the pedestal disposed within the processing chamber through the pedestal shaft. The reference can be a ring and the lateral adjustment assembly substantially centers the pedestal within the ring. A method of adjusting a pedestal includes leveling the pedestal, translating the pedestal, calibrating the pedestal height to a preheat ring level, and checking the level and location of the pedestal while rotating the pedestal.

A micromechanical system for detecting an acceleration includes a substrate, a rocker-like mass structure having a first lever arm and a diametrically opposed second lever arm, the lever arms being situated tiltably at a distance to the substrate and about an axis of rotation to the substrate, and first and second electrodes being provided on the substrate. Each electrode is diametrically opposed to a lever arm and each lever arm includes a section extending from the axis of rotation which is located between the electrodes above an intermediate space. The two sections have different masses.

The invention discloses an independent suspension system which comprises two suspension oil cylinders arranged between the edges of wheels on two sides and a frame respectively, a steering mechanism used for driving the wheels on the two sides to make a turn under the drive action of a power-assisted steering oil cylinder, and two swing rods corresponding to the wheels on the two sides, wherein one end part of each swing rod is hinged to the edge of the wheel on the corresponding side through a spherical hinge, and the other end part of the swing rod is hinged to fixing members fixed below a main speed reducer in a front-rear direction through two spherical hinges respectively. Through the structural improvement, tires mounted on the wheel edges can be positioned, the tire motion in the moving process of a crane is guaranteed to meet the design requirement, and the possible destructive influence of the suspension oil cylinders can be completely avoided, so that the wheels on the left and right sides can reliably and independently move; the adhesion conditions of a road surface are fully utilized, so that the control stability of the complete crane can be improved. Based on the independent suspension system, the invention further provides the crane with the independent suspension system.

A height-adjustable shock pallet includes a lower deck and an upper deck. A central portion of the upper deck is sized to receive a rack-mounted information handling system (IHS) for shipping. Air bags attached between the lower and upper decks are selectively inflatable to protect the rack-mounted IHS during transport and deflatable to position the upper deck proximate to the lower deck for unloading. A controller can detect a tilt of the upper deck and differentially inflate or deflate respective subsets of the air bags to rebalance the upper deck. The controller maintains the rack-mounted IHS horizontal to prevent tipping during transport. Integral or attachable caster wheels can enable repositioning of the height-adjustable shock pallet with the air bags deflated.

A pneumatic isolator for isolating payloads from vibrations consisting of a vertical isolator suspended from pendulum wires. The top load surface of the isolator strongly resists tilt, thus improving payload stability.

Firearms having a carrier assembly, buffer systems, and methods, having a carrier spindle, carrier saddle, or both, to reduce carrier tilt or wobble, reduce wear, or both. A carrier spindle can be located forward of the buffer spring, buffer weight, or both, and aft of the carrier assembly, and can slidably engage the carrier assembly. A spindle spring can bias the carrier spindle aft from the carrier assembly. In some embodiments, a taper on the carrier spindle facilitates separation of the lower receiver from the upper receiver. In some embodiments, the spindle spring is a helical spring that is loaded in compression and pushes the carrier spindle aftward. Some embodiments include a carrier saddle that supports the aft end of the carrier assembly. The carrier saddle can be raised, have a concave top surface, be made of a softer material, have dimensions within certain ranges, or a combination thereof.

The invention discloses a method for compensating imaging quality of an optical system through adjustment of a lens, and is applied to a shooting module applied to an adjustable lens or a lens group.

Provided is a method for manufacturing a semiconductor device in which movement of an island in resin sealing is prevented. A molding die includes an upper die and a lower die. The upper and lower dies are fitted together to form cavities and runners. In the lower die, a pod is provided. After heating and melting of a tablet made of a solid resin and housed in the pod, the melted sealing resin is pressurized by a plunger, and is supplied to each of the cavities. Specifically, a liquid sealing resin is supplied from the pod to the cavities, sequentially, from the upstream of the flow of the sealing resin supplied from the pod. The cavities communicate with each other through the runners. Furthermore, the runners through which the cavities communicate are provided to be tilted with respect to a path for supplying the sealing resin.
