Thermoelectric devices and methods for making the same

Thermoelectric devices having enhanced thermal characteristics are fabricated using multilayer ceramic (MLC) technology methods. Aluminum nitride faceplates with embedded electrical connections provide the electrical series configuration for alternating dissimilar semiconducting materials. Embedded electrical connections are formed by vias and lines in the faceplate. Methods are employed for forming tunnels through lamination and etching. A portion of the dissimilar materials are then melted within the tunnels to form a bond. Thermal conductivity of the faceplate is enhanced by adding electrically isolated vias to one surface, filled with high thermal conductivity metal paste. A low thermal conductivity material is also introduced between the two high thermal conductivity material faceplates. Alternating semiconducting materials are introduced within the varying thermal conductivity layers by punching vias within greensheets of predetermined thermal conductivity and filling with n-type and p-type paste. Alternating semiconducting materials may also be patterned in linear or radial fanout patterns through screening techniques and lamination of wire structures. A liquid channel within the faceplate is used to enhance thermal energy transfer. Thermoelectric devices are physically incorporated within the IC package using MLC technology.

Digital positioner for electric controlled valve and method thereof

The invention discloses a digital electric valve positioner and a method thereof. The positioner consists of a control unit, an I/P electric conversion unit, a valve position feedback unit and a malfunction diagnosis unit. By the configuration of the flux characteristic parameters of the positioner, the working flux characteristic aberration which is caused by the factors such as a change of the pressure drop ratio of the adjusting valve, etc. is corrected, which is based on that a plurality of flux characteristics and action directions of the adjusting valve integration are provided. The control to the valve position of the adjusting valve is based on a Fuzzy-PI dual-mode no-interference shifting algorithm. Depending on the internal relationship between the valve position given value, the valve position feedback value and the valve film head pressure which are arranged by a control center and applying a rule-based knowledge reasoning, the malfunction diagnosis is realized through that the user selects to release or partly release the valve film head pressure during the stuck freeing operation. The valve displacement/electric conversion of the valve position feedback unit depends on a non-contact magnetic sensitive potentiometer. The man-machine interaction adopts a touch screen technique, and the control unit is accessed in a control network by an Ethernet interface.
