Abstract: A method for manufacturing a semiconductor device having an excellent metallization is provided. The method includes the steps of a) providing a semiconductor substrate, b) forming a conductive layer on the semiconductor substrate, c) forming a dielectric layer on the conductive layer, d) forming a titanium nitride layer directly on the dielectric layer without contacting the conductive layer, and e) patternizing the titanium nitride layer, the dielectric layer and the conductive layer, wherein the dielectric layer is used for avoiding spontaneous electrochemical reaction between the titanium nitride layer and the conductive layer.

Abstract: Ethylene/(meth)acrylic acid ionomers which have been modified with relatively low levels of a stearic acid moiety, particularly metal stearates and especially calcium stearate have improved resilience for a given level of hardness or PGA Compression values. The improvement is seen in bulk material when measurements are made on solid neat spheres. When used as cover material, the improvement is more manifest for softer material, and is less, or disappears, for typical mixed metal ionomer hard covers. The stearic-modified ionomers or ionomer blends are especially useful when the ionomer is formulated for use as a golf ball core, center, one-piece ball and as a soft golf ball cover. For covers, softer ionomer compositions will show an improvement.

Abstract: Ionomers based on ethylene/unsaturated carboxylic acid copolymers are modified with from 0.5 to 15 weight percent adipic acid. The modified-ionomers have improved melt flow and melt processing behavior over unmodified ionomers having a comparable level of neutralization of acid groups present. Certain mechanical properties are improved, particularly stiffness, abrasion resistance and low temperature izod impact. The ionomers modified with adipic acid are in particular suitable for balata ball replacement when formulated as golf ball cover compositions and covers.

Abstract: Disclosed are chemical agents with unexpected activity to inhibit the interactions between human immunoglobulin E (IgE) and its receptor (Fc.epsilon.RI) which interactions are known to be involved in triggering allergic responses. The agents may be used to module the allergic response in the treatment of various clinical conditions, including rhinitis, asthma, urticaria, atopic dermatitis, and anaphylacric shock. The agents can be formulated for oral, topical or parenteral administration.

Abstract: A method for purifying protein containing histidine residues using immobilized metal, affinity chromatography. The hydrophilic index of the histidine residues is determined (HI). If the HI is at least 2 the pH of the solution containing the protein is adjusted to about 6.75 to 7.2 and applied to the IMAC column such that the protein binds to the column.

Abstract: A system and method for the filing, retrieving, verifying, translating, exchanging and updating documents by scanning said documents into and storing said documents on a programmed computer system, which system generates or assigns to each document handled a two-dimensionable machine readable image code which contains content and identifying information about the document, as well as information about the document format, and processing instructions. In addition the machine readable image code may contain information concerning textural and/or pictorial content of the document, bio-metric information and the like.

Abstract: An electromechanical gating mechanism comprises an electrical energy generating system for generating electrical energy in response to and utilizing energy derived from mechanical motion consciously generated by an intelligent agency. An electronic decision making apparatus is solely powered by the electrical energy generated by the electrical energy generating device. The decision making apparatus, which may include a non-volatile memory, is adapted to receive information, to make one of a set of possible decisions based on the information and on its logic and/or data in its memory and to generate a specific low power electrical output in response to a selected one of the set of possible decisions being made. A mechanical gate has at least two positions.
