Abstract: A method is described for depositing thick, low-stress refractory metal films on a substrate. For example, a layer of tungsten of any required thickness may be deposited by the silicon reduction of tungsten hexafluoride in a CVD reactor. This is accomplished by alternating the process step of plasma depositing an amorphous silicon film, with the process step of exposing the silicon film to tungsten hexafluoride until the required thickness of tungsten is reached. The thickness of the deposited amorphous silicon film must be less than the thickness at which the conver­sion of silicon to tungsten becomes self-limiting to assure that all of the amorphous silicon is converted. The bombardment of the silicon during the plasma deposition "hammers" the underlying tungsten film and relieves the stress in the film.

Abstract: A function for an electronic typewriter (10) is described. The function assures that when an operator moves the print mechanism back into a region where text has been typed either using a different pitch print element (15) or using a different language keyboard (14), the operation of the typewriter (10) is not enabled until the operator is notified that there exists a condition where a mismatch exists. In the case of the pitch mismatch, the typewriter (10) is only enabled after the operator takes steps to change the print element (15) or position the print point to a position where the mismatch no longer exist. 
     In the situation where a keyboard (14) mismatch exists, the operator must take some step to restart the typewriter operation. This may be the changing of the keyboard (14) to correspond to the keyboard used to key the text in that region, and the changing of the print element (15). The changing of the keyboard (14) may be the only change required, since some languages share print elements.

Abstract: The invention is based on a drying plant for building panels, in particular for fibrous plaster panels or plaster panels containing chips, the panels being placed for drying on a conveyor belt and the water content contained in the panels being removed by supplying heat. In the known drying plants of the convection drier type, the drying process takes a very long time and the strength of the building panels suffers because the water content is removed very quickly on the panel surfaces in particular, as a result of which a disadvantageous dehydration takes place there. 
<??>According to the invention, the drying process is designed in two stages, there being provided for predrying a convection drier, after which there is connected, for post-drying, a high-frequency generator. As a result, a relatively fast drying process and, by the hydration of the surfaces in the drying process, increased strengths of the building panels are obtained.

Abstract: Changes in the  in situ  geometrical and stoichiometric properties of deposited films are brought about by employing a radiation beam directed to a spot which is scanned across the growth surface in a chemical vapor deposition reactor system, e.g., MOCVD system. Gaussian profile spot intensity variations at selected regions at the growth surface will selectively enhance the deposition growth rate and/or  in situ  stoichiometric content of the deposited film. Selective monotonic increasing and decreasing changes in film thickness and stoichiometric content can be accomplished while the spot is scanned across the growth surface. Such changes or variations in film thickness and stoichiometric content are useful in fabricating semiconductor devices having regions of different bandgap and refractive index properties in one or more semiconductor layers of such devices. These property variations may be utilized to produce buried index waveguiding features in such devices and produce multiple emitters each having a different wavelength emission useful in printer and optical communication applications.
