20110100804ELECTROCHEMICAL ANTIFOULING SYSTEM FOR SEAWATER-WETTED STRUCTURES - An electrochemical antifouling system for preventing fouling organisms from adhering to seawater-wetted structures includes a direct current circuit for creating an electrolytic environment in seawater, the direct current circuit having an adjustable direct current source, a lattice electrode having a single metallic component so as to provide a dimensionally stable lattice structure, the lattice electrode electrically insulated from a surface of a seawater-wetted structure, at least one corrosion-resistant counter electrode having polarity opposite to the lattice electrode and disposed at a distance therefrom, and a switching device configured to alternatively switch the lattice electrode to (a) a continuous operating mode, and (b) a temporary depletion mode, wherein the lattice electrode is disposed in a distance range from the surface of the seawater-wetted structure so that the surface lies within an area of influence of an increase in pH value of the seawater caused by electrolysis.05-05-2011
20090206982THIN-FILM RESISTOR WITH A LAYER STRUCTURE AND METHOD FOR MANUFACTURING A THIN-FILM RESISTOR WITH A LAYER STRUCTURE - A thin-film resistor with a layer structure with a Ti layer and a TiN layer is described, wherein a layer thickness of the Ti layer and a layer thickness of the TiN layer are selected such that a resulting temperature coefficient of resistance (TCR) is smaller than 1000 ppm/° C.08-20-2009
