  • Patent number: 6127619
    Abstract: A method for cost-effectively producing thermoelectric elements and thermoelectric modules with a multitude of thermoelectric couples is disclosed. This method makes the fabrication of very small size thermoelectric elements and miniaturized, compact, powerful thermoelectric modules possible. Methods of the present invention can be also used to fabricate integrated thermoelectric modules in electrical or other devices. The invented method is based on an additive technology using thermoelectric pastes and a patternable insulator layer. Layers of conductive traces are first fabricated on the two insulating planes. A patternable insulator layer is formed and filled with P- and N-type thermoelectric pastes. The thermoelectric elements are formed during the curing or sintering of the thermoelectric pastes. Sizes and positions of the thermoelectric elements are defined by the patterned insulator layer.

  • Patent number: 5980785
    Abstract: In accordance with the present invention, there are provided novel metal-containing compositions useful for the preparation of electrical resistance devices (e.g., resistors and thermistor elements). Compositions according to the invention comprise at least one low melting point metal material, and optionally a higher melting point metal material, with the further presence of a binder system also being optional. Compositions according to the invention exhibit a wide range of resistivity and a wide range of values for temperature coefficient of resistance (TCR). Compositions with low values for TCR are useful for resistor applications while compositions with large values for TCR are useful for thermistor applications. Resistor or thermistor elements can be produced by applying compositions according to the invention onto suitable substrates and subsequently alloying (i.e., curing and/or sintering) the compositions.

  • Patent number: 5922397
    Abstract: In accordance with the present invention, it has been discovered that conductive traces made from transient liquid phase sintering (TLPS) pastes, plated by electroless or electrolytic means, result in improved solderability, adhesion and conductivity of the circuitry. Transient liquid phase sintering pastes employed in the practice of the present invention differ from conventional metal loaded polymer thick film (PTF) inks in that they contain, in addition to a binder, they also contain both a relatively high melting metal powder and a relatively low melting solder powder capable of forming a continuous intermetallic/metallic phase after sintering. The present invention is particularly useful, for example, for the fabrication of single and multi-layer printed circuit boards, providing horizontal and vertical conductive interconnects, metallized through-holes, and conductive pads for electronic component attachment.

  • Patent number: 4475204
    Abstract: Flat, transparent slabs of vitreous silica of optical quality are produced by melting granular starting material in a vacuum by means of an electrical heating system. The starting material is melted while sustaining a heat flow from the top to the bottom of the crucible. The bottom of the crucible is made permeable to gases. The heat isolation power of the crucible wall increases from the bottom to the top of the crucible.
