Abstract: An exterior material (6) such as a tile which is likely to flake due to cracks or other possible defects in the wall base (2) of a concrete structure can be effectively repaired by boring an anchor hole (24) extending from the surface of the exterior material (6) to the concrete wall base (2), and inserting and inflating an expansion anchor bolt (26) in the anchor hole (24). By using a drilling device (10) capable of spouting out a cooling fluid while drilling, even hard nonmetallic material such as a ceramic tile can be effectively bored to form a suitable anchor hole (24).

Abstract: A suitable inert gas such as argon or a mixture of inert and reactive gases such as argon and hydrogen is introduced onto the backside of wafers being processed in a CVD reactor during the deposition of tungsten or other metals, metal nitrides and silicides, to avoid deposition of material on the backside of the wafers being processed. Each process station (4b,4c,4d) includes a gas dispersion head (12b,c,d) disposed over a platen (14b,c,d). A vacuum chuck including a number of radial and circular vacuum grooves in the top surface of the platen is provided for holding the wafer in place. A platen heater is provided under the platen. Backside gas is heated in and about the bottom of the platen, and introduced through a circular groove in the peripheral region outside of the outermost vacuum groove of the vacuum chuck. Backside gas pressure is maintained in this peripheral region at a level greater than the CVD chamber pressure. In this manner, backside gas vents from beneath the edge of the wafer on the platen and prevents the process gas from contacting the wafer backside. If the process gas is also to be prevented from contacting the periphery of the wafer frontside, a shroud is urged against the platen to direct the backside gas into a cavity formed between the shroud and the platen. This cavity contains the wafer frontside periphery, so that backside gas venting from between the shroud and the wafer frontside periphery excludes the process gas.

Abstract: Mit dem erfindungsgemäßen Verfahren wird eine Anfangssynchronisation und eine Anpassung eines Empfangsfilters eines digitalen Empfängers in einem binären Basisbandübertragungssystem durch Einsatz einer Trainingssequenz vor der Übertragung von Nutzdaten erreicht. Durch eine spezielle Trainingssequenz werden die Koeffizienten für ein auf das Empfangssignal anzupassendes digitales Filter erreicht. Die Zeichensynchronisation und das Erkennen des Endes der Trainingssequenz erfolgt selbsttätig. Nach Empfang einer Trainingssequenz steht im Empfänger ein optimal angepaßtes Empfangsfilter zur Verfügung. Das Verfahren ist innerhalb einer vorgegebenen Rechengenauigkeit unabhängig vom Pegel des Empfangssignals; es läßt sich mit einem herkömmlichen Signalprozessorsystem implementieren. <IMAGE>

Abstract: The plateau region of P-C-T isotherm of a hydrogen absorbing alloy between the α phase region and β phase region thereof is expressed by a normal cumulative distribution function wherein hydrogen content X is taken as frequency and the logarithm of equilibrium hydrogen pressure as a random variable. Parameters such as standard deviation σ of the function are determined by numerical analysis based on measured data as to the equilibrium hydorgen pressure and hydrogen content of the plateau region of the alloy to be evaluated. Whether the equilibrium characteristics of the alloy are acceptable is determined using the parameters as evaluation criteria.
