Procedure for equilibration of the delivery volumes of a multi-channel metering apparatus with an arrangement of independently controlled dispensing channels 1.1-1.n, delivering individual volumes of dispensing fluid to cavities 3.1.1-3.n.n, where measured values relevant to the individual delivery volumes are measured for the same control value and from which an adjustment value is specified with a tolerance band and the control value is adjusted for dispensing channels 1.1-1.n, the measured values of which lie outside the tolerance band. The invention also applies to an apparatus for implementing the procedure.

A performance analysis support system is disclosed that provides one or more recommended solutions of a performance improvement project to management and the expected improvement benefit of each solution. The performance analysis support system guides a user through a detailed, consistent analysis process, helping organizational leaders accurately diagnose critical performance or productivity issues. Then, the performance analysis support system estimates the personnel and equipment requirements, time, costs, and return on investment associated with each solution generated based on the analysis results. In addition, the performance analysis support system provides management immediate access to ongoing and past analyses.

We disclose an apparatus and method for detecting probe-tip contact with a surface, generally inside a focused ion-beam instrument, where the probe tip is attached to a capsule, and the capsule is movably secured in a probe shaft. There is a fiber-optic cable having a first end and a second end; a beam splitter having first and second output ports; and a light source connected to the beam splitter. The first output port of the beam splitter is connected to the first end of the fiber-optic cable, and the second output port of the beam splitter is connected to a photodiode. The second end of the fiber-optic cable has a mirror for reflecting incident light at approximately a ninety-degree angle to the axis of the optical path in the fiber-optic cable and onto the capsule, so that the intensity of the light reflected back from the capsule through the fiber-optic cable is proportional to the deflection of the capsule as the probe tip makes contact with the surface.

摘要:
An enclosure constructed of vinyl foam filled blow-molded panels. These panels are structured with tongue and groove connections built in to provide quick interlock one to another without the need for tools in assembly or disassembly. The construction characteristics provide panels that are rigid, strong, insulated, sound deadened with high flotation qualities. The enclosure is transportable by towing the assembled structure on a built-in sled bottom or dissembling the panels, stacking them and transporting them in a vehicle.

We disclose a gripper and associated apparatus and methods for delivering nano-manipulator probe tips inside a vacuum chamber. The gripper includes a tube; a compression cylinder inside of and coaxial with the tube; and at least one elastic ring adjacent to the compression cylinder. There is a vacuum seal coaxial with the compression cylinder for receiving and sealing against a probe tip. An actuator is connected to the compression cylinder for compressing the elastic ring and causing it to grip the probe tip. Thus the probe tip can be gripped, transferred to a different location in the vacuum chamber, and released there. Samples attached to the probe tips will be transferred to a TEM sample holder, shown in several embodiments, that includes a bar having opposed ends; an arm attached to each opposed end of the bar; one or more slots for receiving a probe tip; and, each slot having an inner part and an outer part, where the inner part is smaller than the outer part. The TEM sample holders just described are inserted into a carrier cassette. A cassette for transferring one or more TEM sample holders comprises a platform; at least one bar extending upwardly from the platform; the bar having a groove for receiving and holding a TEM sample holder. A rotatable magazine holds one or more probe tips and selectively releases the tips. The magazine includes a cartridge having a plurality of longitudinal openings for receiving probe tips and dispensing probe tips.

A molding machine having a mold including upper and lower mold plates, an upper heat transfer platen connected to the upper mold plate, and a lower heat transfer platen connected to the lower mold plate. Each mold plate contains mold cavities. When the mold plates are aligned and abutted, mold locations from the upper and lower mold plates cooperate to form mold volumes. Each of the heat transfer platens contain two series of independent channels for supplying heat transfer media to control the temperature of the material being molded. Each series of channels includes feeder channels and transverse channels. All of the transverse channels of a heat transfer platen are substantially coplanar and parallel. A plurality of adapters supplies heat transfer media to the channels. A ram is connected to one of the heat transfer platens. A control system controls movement of the ram. A protection device continuously monitors the operation of the molding machine. The protection device monitors the movement and position of the ram and the pressure exerted by the ram. The control system contains a plurality of triggers to ensure the molding machine is operated under predetermined conditions.

摘要:
An arrangement for transporting microtitration plates in an automatic handling machine is disclosed comprising at least one linear-transport device on which a carriage, which has at least one place of deposit for a microtitration plate, is transported in a straight line, under automatic control, between two limit positions. A lifting device is included with vertically displaceable bolts by which the microtitration plates can be lifted off or deposited on the carriage. At least one rotary device is also included in which a rotary element which has at least one resting place for a microtitration plate can be moved, under automatic control, about a fixed rotation shaft. The rotary device is designed and arranged in such a way with respect to the linear-transport device that the resting place can be rotated between the place of deposit and the microtitration plate which has been lifted and is resting on the bolts, so that the surface centers of gravity of the place of deposit of the resting place and of the microtitration plate lie on a line which is parallel to the bolts.
