摘要： A clamping device is provided for clamping an object, such as bonding wire for a wire bonding machine. The device comprises a pair of clamping arms arranged in pivotal relationship with each other about a pivot point, the clamping arms having clamping ends movable between an open position and a closed position. An attraction device is operative to provide an attraction force between the clamping arms about the pivot point. The device includes biasing means that is operative to provide a biasing force in opposition to the attraction force about the pivot point, such that the biasing force is operative to bias the clamping ends towards the closed position. In a preferred embodiment, the biasing means comprises a flexure bearing.

摘要： An apparatus is disclosed for moving an optical component of an opto-mechanical inspection system relative to an object to be inspected using a linear actuator comprising a coil located in a magnetic field created by a magnet assembly. A translation stage is coupled to either of said coil and magnet assembly whereby the translation stage is configured for motion relative to the other of said coil and magnet assembly. Movement of the translation stage is configured along a plane that is substantially perpendicular to a direction of incident light projected from a light source through the optical component onto the object.

摘要： The miniaturized piezoelectric accelerometer includes a support frame (102) having a cavity (104) and a seismic mass (108) supported by a plurality of suspension beams (110) extending from the support frame (102). Each of the suspension beams (110) has a piezoelectric thin film coated on a top surface thereof, with a pair of inter-digital electrodes (114) deposited on an upper surface of each piezoelectric thin film. The presence of acceleration excites bending and thus strain in the piezoelectric thin film, which in turn causes electrical signals to be generated over terminals of the electrodes (114). To collect constructively the output of the electrodes (114), one terminal of each of the electrodes (114) is routed to and electrically connected at a top surface (308) of the seismic mass (108).
