Abstract: An apparatus and method for applying a coating to glass including a support surface for supporting a glass pane, a print screen having a screen support frame defining a perimeter of the print screen disposed above the support surface to apply a coating over the print screen. The print screen is deflected into contact with the glass pane at predetermined points thereon and the coating is moved over the print screen to deposit the coating on the predetermined points on the glass pane when the print screen is so deflected. The apparatus also includes a vapor manifold having a predetermined width disposed within the perimeter defined by the screen support frame and coupled to a source of vapor. The vapor manifold distributes a vapor blanket over the print screen and the glass pane, thereby reducing the rate at which the coating on the glass pane dries and impede evaporation of the coating from the print screen.

Abstract: An on-board gas composition sensor is disclosed for monitoring oxygen content levels in the exhaust gas of an internal combustion engine. The gas composition sensor includes a light source for generating excitation light, e.g. in the 350-525 nm wavelength range. A sensor body of porous high-temperature fluorescent inorganic oxide ceramic exposed to the exhaust gas emits an optical fluorescence signal responsive to oxygen content in the exhaust gas upon exposure to the excitation light at 400.degree.-650.degree. C. A florescence detector receives the optical fluorescence signal from the sensor means and generates an exhaust gas oxygen content output signal in response. Fiber-optic cable can be employed for transmitting excitation light to the sensor body from a remotely located light emitter. The same or a separate fiber-optic cable can transmit the optical fluorescent signal from the sensor body to the fluorescence detector also at a remote location.

Abstract: An electrically heated window assembly and method for heating a movable front door window (side lite) of a motor vehicle defrosts and deices the front window by producing a concentration of heat at the portion of the front window through which an operator or passenger of the vehicle views an exterior rear view mirror. To heat the window, a current flows between a first bus bar, positioned along the front edge of the window, and a second bus bar, positioned along the rear edge of the window. A conductive film provides the current path between the respective bus bars. A nonconductive break is formed in the conductive film substantially along the nominal door line of the window to prohibit heating of the window below the nominal door line. The first bus bar may preferably be arcuately-shaped to provide a uniform heating pattern on the window. Various control devices, such as temperature sensors and position sensors, are used to control the heating process.

Abstract: A crystalline silicon carbide film is grown on a heated crystalline silicon substrate by laser ablation of a pure carbon target. For substrate temperatures during deposition above 1000.degree. C. and single crystal silicon substrates the resulting SiC film is expitaxially oriented with respect to the substrate. Films of stoichiometric SiC are grown up to thicknesses of about 4000.ANG.. These films grow on top of the silicon substrate and whereas the source of carbon for the film is from the ablation plume of the carbon target the source of the silicon is from the substrate. By using a method of alternate ablation of a pure carbon and a pure silicon target, similar epitaxial films can be grown to thicknesses in excess of 1 .mu.m with part of the silicon being supplied by the ablation plume of the silicon target.
