Abstract: The present invention relates to a low-pressure chemical vapor deposition (LPCVD) process for de­positing silicon dioxide. In particular, the present invention describes a process involving a pre-cleaning step in which all impurities are removed from the substrate followed by a LPCVD step performed at temperatures of between 200°C and 300°C. 
     More particularly, the present invention involves a process in which a substrate is washed using a pre­determined cleaning process. The substrate is then exposed to a dilute hydrofluoric acid solution which removes native oxide and contaminants from the surface. Next, the substrate is rinsed with, for example, de-ionized water or ultra-clean water to remove any hydrofluoric acid or other residue from the previous process steps. A layer of semiconductor material, for example, silicon dioxide, is then deposited using a low-pressure chemical vapor deposition process in which the gas flow comprises silane, oxygen and nitrogen at temperatures below 300°C. Oxide qualities approaching those of thermally grown oxides have been achieved.

Abstract: A process for the separation of contaminants and toxic substances from waste water passed into tanks or vessels (100) is proposed. The tanks or vessels are equipped with built-in elements (101), which can be formed as brushes, rods, nets, strips or the like, and which are provided with a biofilm. The built-in elements on the one hand receive deposits of materials which favour the growth of the biofilm, and on the other hand the flow is altered so that the sedimentation of sedimentable materials is improved. At preset intervals, the new growth of biofilm is mechanically removed by scraping devices in such a manner that part of the biomass remains on the built-in elements, so that growth of organisms can again take place there. <IMAGE>

Abstract: A double-acting, rotating piston reciprocating in a cylinder with the motion of the piston providing the valving action of the Sibling Cycle through the medium of passages between the piston and cylinder wall. The rotating piston contains regenerators ported to the walls of the piston. The piston fits closely in the cylinder at each end of the cylinder except in areas where the wall of the cylinder is relieved to provide passages between the cylinder wall and the piston leading to the expansion and compression spaces, respectively. The piston reciprocates as it rotates. The cylinder and piston together comprise an integral valve that seqentially opens and closes the ports at the ends of the regenerators alternately allowing them to communicate with the expansion space and compression space and blocking that communication. The relieved passages in the cylinder and the ports in the piston are so arranged that each regenerator is sequentially (1) charged with compressed working gas from the compression space; (2) isolated from both expansion and compression spaces; (3) discharged of working gas into the expansion space; and (4) simultaneously charged with working gas from the expansion space while being discharged of working gas into the compression space, in the manner of the Sibling Cycle. In an alterate embodiment, heat exchangers are external to the cylinder and ports in the cylinder wall are alternately closed by the wall of the piston and opened to the expansion and compression spaces through relieved passages in the wall of the reciprocating, rotating piston.
