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.

Wood floor with decorating patterns and manufacturing method thereof

The invention relates to a wood floor and a manufacturing method thereof. The wood floor with decorating patterns comprises a base material layer, a decorating pattern layer and a protective layer, wherein the decorating pattern layer is arranged on the base material layer and printed by a silk-screen technique and a transfer printing technique or a computer color printing technique, and the protective layer is arranged on the decorating pattern layer. The manufacturing method of the wood floor with the decorating patterns comprises the following steps: (a) coating base paint on the right sides of base materials and also drying the base paint; (b) sanding the base paint of the step (a) and coating a second base paint layer; (c) printing patterns on the surface of the second base paint layer of the step (b) by utilizing the silk-screen technique and the transfer printing technique or the computer color printing technique; (d) covering the protective layer on the pattern surface; and (e) cutting blanks to form floor dimensions. The invention prints the patterns on the base materials through the silk-screen technique and the transfer printing technique or the computer color printing technique so that the adhesive force of the patterns is strong, thereby enhancing the stability of the wood floor; and in addition, the invention enhances the availability of regenerated woods, thereby reducing the production cost.
