摘要： The invention provides an apparatus and method for the active alignment and coupling of separate optical components consisting of a light-emitting component and a light-receiving component. It comprises first alignment means having a relatively lower optical resolving power stage that is adapted to perform coarse alignment of the light-emitting component to locate an approximate location of its point of highest intensity, and second alignment means having a relatively higher optical resolving power stage that is adapted to perform fine alignment of the light-emitting component to locate a more precise location of the said point of highest intensity. Accordingly, coarse alignment may be performed using a multi-mode fiber and fine alignment may be performed using a single-mode fiber that may further be coupled to the light-emitting component.

摘要： The invention provides an apparatus and method for aligning a bonding tool. A force sensor having a plurality of force sensing sections is configured to measure a force generated by the bonding tool on the force sensor. Each sensing section is adapted to individually detect an amount of force from a part of the bonding tool acting on that sensing section, so that an alignment of the bonding tool may be determined.

摘要： A damping apparatus is provided for a positioning stage that is operative to move and position an object along a motion axis. The damping apparatus comprises a motion transformation device operative to rotate the positioning stage about a rotary axis that is substantially perpendicular to the motion axis, in response to forces generated to the positioning stage during acceleration or deceleration thereof. Resilient elements connected to the positioning stage serve to reduce transmission of vibration generated from the positioning stage.

摘要： This invention concerns particulate reinforced Al-based composites, and the near net shape forming process of their components. The average size of the reinforced particle in the invented composites is 0.1–3.5 μm and the volume percentage is 10–40%, and a good interfacial bonding between the reinforced particulate and the matrix is formed with the reinforced particles uniformly distributed. The production method of its billet is to have the reinforced particles and Al-base alloy powder receive variable-speed high-energy ball-milling in the balling drum. Then, with addition of a liquid surfactant, the ball-mill proceeds to carry on ball-milling. After the ball-milling, the produced composite powder undergoes cold isostatic pressing and the subsequent vacuum sintering or vacuum hot-pressing to be shaped into a hot compressed billet, which in turn undergoes semisolid thixotropic forming and may be shaped into complex-shaped components. These components can be used in various fields. This product is featured with excellent property, good machinability, stable quality, component near net shape forming and cost effective and higher performance.
