Patent SE-7606869-L (SE)
Inventor: PETROFF P M
IPC: H01L29/73
Filed: 1976-06-16
Abstract: Described are procedures for fabricating silicon devices which prevent the formation and/or activation of stacking fault nucleation sites during high temperature processing steps, such as steam oxidation of silicon wafers. The procedures, which take place before such high temperature steps, include forming on the back surface of the wafer a stressed layer and then annealing the wafer for a time and at a temperature effective to cause the nucleation sites to diffuse to a localized region near to the back surface. Illustratively the stressed layer comprises silicon nitride or aluminum oxide. Enhanced gettering is achieved if, prior to forming the stressed layer, interfacial misfit dislocations are introduced into the back surface by, for example, diffusion of phosphorus therein. Following the gettering step(s) on the back surface, conventional procedures, such as growing epilayers and/or forming p-n junctions, are performed on the front surface of the wafer.

Abstract: A low cost, simple to manufacture, two axis gyro having an outer flexure assembly and an inner flexure assembly. Each flexure assembly contains two flexure hinges which represent a reduction in the number of hinges and milled cuts from those required in prior art devices.  The inner flexure assembly is designed to nest within the outer flexure assembly and both are mounted centrally on a rotatable shaft for rotation about the gyro spin axis.  The two flexures of the outer assemblies are separated 180.degree. from each other and adjacent to two slots also separated by 180.degree. in the rim of the outer gimbal.  Likewise, the two flexures of the inner flexure assembly are separated 180.degree. from each other and 90.degree. from each of the outer flexures.  The outer flexure assembly axis is offset axially by a controlled amount from the inner flexure assembly axis to achieve nominal balance on both flexure axes.

Abstract: The invention relates to a process and device for the production of a plastic hose with a wick that is arranged in it and is longer than the hose, the latter being intended for watering flowers and the like. The hose 2 in question is intended to be wound on a reel 1 shaped like a regular polygon and having notches 5, which during the winding process come to lie straight in front of the corners 6 of the reel 1. As a result, the hose 2 wound up on the reel 1 forms straight parts 8 extending along the sides 7 of the reel 1 using the open ends situated in the corners 6. The reel 1 is turned in stages, so that the said straight parts 8 successively come to lie in front of a hook arrangement 9. The latter is led back and forth through the straight parts 8, so that the hook arrangement 9 introduces into the parts 8 some wicks that are longer than the parts 8. The device consists of a reel 1 that is rotatably mounted on a bearing at its centre 3 and has the shape of a regular polygon, which is arranged to rotate in stages. The reel 1 cooperates with a cutting device 4 in order to furnish the hose 2 wound up on the reel 1 with notches 5. The reel 1 also cooperates with a hook arrangement 9, which is provided in order to introduce - during the rotation of the reel 1 in stages - the wicks into the straight parts 8 situated along the polygonal sides 7 of the hose 2. <IMAGE>

Abstract: Comprehensive shunting systems for draining fluid from a region of the body, such as in the treatment of hydrocephalus. The shunting systems greatly improve the drainage of such fluid and are capable of attaining a significantly extended lifetime of service within the patient being treated. A catheter accommodates the growth of the patient, even when the shunt system is inserted within an infant. The shunt systems improve drainage of fluid through a shunt by preventing proteinaceous buildup resulting in shunt malfunction. In addition, an improved proximal catheter is disclosed which is capable of being caused to assume a position spaced from the body tissue, i.e., ventricular lining. Valve assemblies attain pressure regulation, such that stagnant reservoirs or columns of fluid are eliminated to prevent formation of sediment and ultimately valve malfunction, and collapse of a body cavity due to evacuation of fluid is not encountered. A trocar for inserting the catheter into the body for ease of the patient and surgeon. A syphon effect within the shunt system is also prevented and a variable pressure response of a slit valve at the time of surgery is provided.

Abstract: In a central heating system, the temperature (tw) of the heating fluid is controlled depending on the outdoor temperature (tu) and the indoor temperature (ti). A non-linear operating graph presenting the relation between the outdoor temperature (tu) and the heating-fluid temperature (tw) is approximated by a sequence of linear sections (a, b, c, d) of different steepness, the location of the transit points between the sections being determined by the difference between the desired reference temperature (to) and the sensed indoor temperature (ti). Thus, the system optimizes the heating curve in a self-adaptive way.

Abstract: A transport and storage container for low and medium level radioactive waste is sealed with an external cover after being charged with a receptacle insert. The receptacle insert has a cup-like configuration and is arranged in the storage container and adapted directly to receive the radioactive waste. The storage vessel and the receptacle insert conjointly define an annular space therebetween. The storage container must be appropriate for remotely-controlled handling and must have the greatest possible capacity per drum. For this purpose the top of the receptacle insert has a radially extending centering ring at the edge of its opening with segment-like recesses disposed in spaced relationship to each other around its periphery. The wall of the insert tapers downwardly toward the base thereof. A supporting ring extends around the outer periphery and is arranged on the external surface of the insert in spaced relationship to the centering ring and its outer diameter is greater than the inner diameter of the centering ring. The invention is also directed to a method of charging such a container for low and medium level radioactive waste.

Abstract: A supply tank for supplying fluid to a tandem master brake cylinder of a motor vehicle. The tank has a bottom section and a top section which is not shown. The bottom section comprises a partition wall which separates the two chambers from each other, the partition wall being formed with a passage which is arranged approximately in the center of the bottom section. In each chamber, an outlet is configured at each end of the bottom section. From each outlet and along the partition wall toward the middle of the bottom section, there extends one pipe which has an opening respective at its free end. The openings are positioned below the minimum admissible fluid level. The purpose achieved by the configuration of the pipes within the supply tank is that the effect of an inclination of the supply tank does not impair the efficiency of the hydraulic fluid and that, consequently, the outlets are supplied with hydraulic fluid at all times and in any condition.

Abstract: A method of removing nitrogen and phosphorus from waste water by using an activated sludge including aerobic bacteria is disclosed. The waste water is fed continuously and gradually into a treatment basin in which the sludge is contained so that a mixed liquor consisting of the waste water and the sludge is formed therein. A cycle consisting of an agitating step and an aerating step is repeated at least two times and each cycle is finished within two hours, with the ratio of the agitating time to the aerating time being between one to one and to one. In the agitating step, the mixed liquor presents an anoxic condition and a succeeding anaerobic condition. Denitrification occurs in the anoxic condition and the aerobic bacteria release phosphorus in the anaerobic condition. During the aerating step, nitrification is caused while the bacteria excessively ingest phosphorus from the mixed liquor.
