摘要:
An optical system performs imaging in a transmissive and reflective mode. The system includes an optical interferometer that generates interference phenomena between optical waves to measure multiple distances, thicknesses, and indices of refraction of a sample. Measurements are made through a galvanometer that scans a pre-programmed angular arc. An excitation-emission device allows an electromagnetic excitation and emission to pass through an objective in optical communication with the sample. An electromagnetic detector receives the output of the optical interferometer and the excitation-emission device to render a magnified three dimensional image of the sample.

An optical system includes more than two optical interferometers that generate interference phenomena between optical waves to measure a plurality of distances, a plurality of thicknesses, and a plurality of indices of refraction of a sample. An electromagnetic detector receives an output of the optical interferometers to render a magnified image of at least a portion of the sample. A controller reduces or eliminates undesired optical signals through a hierarchical phase unwrapping of the output of the electromagnetic detector.

An apparatus and method for depositing plural layers of materials on a substrate within a single vacuum chamber allows high-throughput deposition of structures such as these for GMR and MRAM application. An indexing mechanism aligns a substrate with each of plural targets according to the sequence of the layers in the structure. Each target deposits material using a static physical-vapor deposition technique. A shutter can be interposed between a target and a substrate to block the deposition process for improved deposition control. The shutter can also preclean a target or the substrate and can also be used for mechanical chopping of the deposition process. In alternative embodiments, plural substrates may be aligned sequentially with plural targets to allow simultaneous deposition of plural structures within the single vacuum chamber. A monitoring and control device can be wed to optimize equipment state, process state, and wafer state parameters by sensing each respective state during or after the deposition process.

A shut-off system for a dispenser includes a pinch member that moves relative to a guide and which is normally biased against a flexible outlet tube that is disposed therebetween. The flexible outlet tube that carries material, such as soap, supplied from a pump to an outlet nozzle. The pump and the pinch member are in operative engagement with an actuator, such that when the actuator is not engaged, the pinch member closes the outlet tube to prevent residual material retained in the outlet tube from flowing or drooling out of the outlet nozzle. Correspondingly, when the actuator is engaged, the pump is compressed, and the pinch member is moved away from the outlet tube, allowing the material to be pumped through the outlet tube and dispensed from the outlet nozzle.
摘要:
Exemplary simplified outlet valves, pumps and refill units are disclosed herein. An exemplary inverted refill unit for a dispenser includes a container and a pump secured to the bottom of container. The pump has a liquid inlet valve and a liquid outlet having an annular housing. One or more liquid outlet passages are located within the annular housing. A valve seat is located proximate the liquid outlet passages. A liquid outlet valve is also included. The liquid outlet valve includes an annular body and a resilient disc located on the interior of the annular body. The resilient disc has an opening in the center and seals against the valve seat to seal the one or more liquid outlet passages in a normal state. The resilient disc deflects from the valve seat under pressure so that liquid flows through the liquid outlet passages and through the center of the resilient disc.
