摘要:
An emitted energy system for use in photolithography may include a holder assembly operable to precisely align a diffuser and a nozzle. In accordance with one embodiment of the present invention, a holder assembly (30) may comprise a nozzle mounting system (414) coupled to a housing assembly (400) to secure a nozzle (22). A diffuser mounting system (430) may be coupled to the housing assembly (400) to secure a diffuser (28). An alignment system (450) may operate to align the nozzle (22) and the diffuser (28) in a spatial relationship with each other to optimize operation of the diffuser (28) in relation to the nozzle (22).

An emitted energy system for use in photolithography may include a fluid nozzle. A nozzle and its method of manufacture are provided. A nozzle (22) may include a nozzle cavity (110) disposed within a nozzle body (100) between an up-stream end (102) and a down-stream end (104). A nozzle passage (118) may be defined within the nozzle cavity (110) and extend a longitudinal length (120) from the down-stream end (104) of the nozzle body (100) into the nozzle cavity (110). A discharge orifice (124) may also be defined at the down-stream end (104) of the nozzle cavity (110) and have an associated width (126). The width (126) of the discharge orifice (124) may be substantially less than the longitudinal length (120) of the nozzle passage (118).
摘要:
An optical mounting system is configured so as to locate a 360.degree. shoulder all around the optical element periphery in both the object and image sides of the optical element. The shoulder allows expansion or contraction of the optical element both in the thickness direction of the optical element and in the direction normal to the optical axis when installed in the mounting assembly. Three small metal clips are used to maintain centering of the optics, the thermal expansion and contraction of these clips being coordinated with the clip geometry so that the optical material remains centered without induced stress or free play at either room temperature or at the operating temperature.
摘要:
An x-ray focusing device and method for adjustably focusing x-rays in two orthogonal directions simultaneously. The device and method can be operated remotely using two pairs of orthogonal benders mounted on a rigid, open frame such that x-rays may pass through the opening in the frame. The added x-ray flux allows significantly higher brightness from the same x-ray source.

摘要:
A method for automatically minimizing an undesirable motion of a workpiece during a machining operation, and a universal adaptive machining chatter control fixture that operates in accordance with the method. The method comprises the steps of mounting the workpiece to an active, supporting structure, and then machining the workpiece. During the step of machining, an undesirable motion of the workpiece is sensed in the supporting structure. Thereafter, a compensating motion is applied to the supporting structure for minimizing the undesirable motion of the workpiece. The chatter control fixture can be attached to various types of machine tool devices, without requiring that the machine tool devices be retrofitted, and operates to minimize undesirable motions of the workpiece independently of the machine tool devices.

A strain gage assembly 10 includes a mounting substrate 12 having an adhesive surface 14 and a gage surface 16. The adhesive surface 14 of the mounting substrate 12 includes an adhesive layer 18 disposed thereon operable to affix the mounting substrate 12 to a component. The adhesive layer 18 is further operable to allow ready detachment of the mounting substrate 12 from the component. The gage surface 16 of the mounting substrate 12 includes a strain gage 20 disposed thereon. The mounting substrate 12 may be formed from a material operable to reduce a strain level received by the strain gage 20.
摘要:
An interferometer comprising a base forming an interior, and first and second optical members located in the interior of the base. The interferometer further comprises a first retainer assembly connecting the first optical member to the base, translation means for moving the second optical member relative the first optical member to vary the distance between the first and second optical members, and a second retainer assembly connecting the second optical member to the translation means. The preferred mechanical configuration and design features of the interferometer produce a very durable instrument that can rapidly scan and accurately filter light across a wide bandwidth. This uniquely designed instrument combines high speed switching, high resolution, wide bandwidth, and adjustable damping capabilities in a durable flight capable instrument.
摘要:
A gauge for measuring an out-of-plane surface displacement profile around a cold-worked fastener hole in relation to the distribution of residual compressive stresses around the hole and related fatigue life. The gauge has a deformable strain sensor positionable to be deformed in accord with the out-of-plane surface of the structural material circumferentially surrounding the cold-worked hole. A measurement reporting readout device is in communication with the strain sensor and relates three-dimensional surface-profile measurement data in accord with strain sensor deformation to determine or verify the cold expansion magnitude, uniformity and consequent fatigue life through three-dimensional elastoplastic finite element comparative analyses and/or experimental measurements for a hole in any material of given thickness.
