摘要： A ferrule for an optical fiber connector having open fiber clamping grooves. The ferrule has a body having a plurality of open grooves for clamping the terminating end sections of optical fibers. At least a section of the longitudinal opening of the groove is provided with opposing lips to provide a clamping effect. The width of the longitudinal opening defined between the lips along at least a section of the grooves is narrower than the diameter of the optical fibers to create a tight fit. The grooves and the width of the longitudinal groove openings are shaped and sized to retain the fibers without any clearance to allow for movement of the fiber relative to the groove. Similar grooves may be provided in the ferrule body for alignment guide pins. The grooves are precision formed by high throughput processes, such as stamping and extrusion.

摘要： Instruments and methods for measuring a property of a shape memory alloy are provided. The instrument includes a base plate, a non-contact movable mass, a force gauge, an actuator, a biasing spring, a heater for heating the shape memory alloy, and a non-contact displacement detector. The biasing spring and the shape memory alloy are disposed whereby a force applied thereby is applied substantially through a center of stiffness of the movable mass. The displacement detector measures a displacement of the movable mass in a colinear direction with a direction of movement of the movable mass and with a direction of the force applied by the biasing spring and the shape memory alloy. The linear motion stage comprises a housing and at least one guide bar, and wherein a calculated axial expansion of the guide bar is substantially equal to a calculated axial expansion of the base plate.

摘要： A linear actuator is provided, comprising a housing defining an interior channel, a stop extending from the housing and displaceable relative to the housing, and at least one wire formed of a shape-memory alloy, the wire being attached at a first end to the stop and at a second end to the housing. When heated to a predetermined temperature, the wire applies a pulling force to the stop to cause the stop to slide in a first direction into the housing interior channel. A spring located in the housing interior channel applies a biasing force to the stop in a second direction counter to the first direction when the wire cools, thereby returning the stop to the unactuated position. A wire heater is provided, which may be an electrical source for resistive heating of the wire. Multiple actuators of the present invention may be configured in parallel to increase the force generated by the wires. In yet another embodiment the actuators of the invention may be arranged in a serial configuration for controlling a rotary or carousel dispenser.

摘要： Novel methods and devices for nanomachining a desired pattern on a surface of a conductive workpiece are disclosed. In one aspect, the method comprises using an electron beam emitted from one or more nanotubes to evaporate nanoscale quantities of material from the workpiece surface. The surface of the workpiece to be machined may be excited to a threshold energy to reduce the amount of power required to be emitted by the nanotube. In another aspect, a device is described for nanomachining a desired pattern on a surface of a conductive workpiece, comprising a vessel capable of sustaining a vacuum, a leveling support, a nanopositioning stage, and a laser for heating the workpiece. A nanotool is provided comprising at least one nanotube supported on an electrically conductive base, adapted to emit an electron beam for evaporating material from an electrically conductive workpiece.
