Latest Patents
Dorfeld's latest patents include a resistor composition and method of manufacture. This invention discloses a range of resistor compositions that exhibit a stability of less than 0.5 percent change in resistance after 2,000 hours at 175 degrees Celsius. These compositions also have a temperature coefficient of resistance of less than ±25 ppm per degree Celsius. The compositions comprise alloys of nickel, chromium, and silicon within a selected range. Additionally, the patent outlines a method of manufacturing these compositions on a reproducible basis, which includes the use of silicon and nickel chromium targets subjected to sputtering gas and electrical potential.
Another significant patent involves a process for enhancing the adhesion of coatings applied to glass-ceramic articles. In this method, the surface area to be coated is roughened before the article is completely cerammed. When subjected to elevated temperatures, flaws produced by the abrasion step are healed, allowing for coatings to be applied either before or after the ceramming step.
