Abstract: Une méthode de représentation de variations régionales de petites amplitudes au niveau de la position du géoïde est décrite. Les ressources naturelles ayant une densité différente de celle des milieux environnants dans le fond marin peuvent provoquer des variations de hauteur de la surface de la mer par rapport à un niveau de référence. Des valeurs de hauteur sont obtenues au moyen de données altimétriques provenant d'un avion en vol, les orbites de l'avion étant adaptées entre elles. Des variations d'ondes longues avec une longueur d'onde dépassant environ 200 km dans la position du géoïde sont éliminées par filtration. Des variations dans la position du géoïde qui se trouvent dans une fourchette sélectionnée sont amplifiées, et la position du géoïde est corrigée par rapport aux interférences provenant de la profondeur de l'eau.

Abstract: An immunoassay utilizing a biotin bridge is performed with a solid phase with anti-biotin immobilized on its surface. In accordance with the assay, the solid phase is incubated with a biotinylated binding species, preferably biotinylated antibody, specific for the ligand to be detected. This is then reacted with the test sample, followed by a labeled binding member, either in a sandwich-­type or competitive-type binding assay. The label is then detected in accordance with conventional detection techniques. Use of the solid phase with only a biotin-­specific antibody attached thereto expands the utility and versatility of a single solid phase for use in the detection of an unlimited variety of ligands.

Abstract: To produce corrosion- and wear-resistant protective coatings on magnesium or magnesium alloys by anodic oxidation, use is made of a low-alkali aqueous electrolytic bath which contains
 a) borate or sulphate anions, and
 b) phosphate and fluoride or chloride ions
 and which is adjusted to a pH of 5 to 11, preferably 8 to 9. The applied direct current is interrupted for a short time or partially reversed in order to permit the formation of magnesium phosphate and magnesium fluoride or chloride and, possibly, magnesium aluminate. This produces coatings without or with only very slight inherent coloration which can readily be coloured and which yield a good adhesive base for lacquer coatings or post-treatments.

Abstract: An automatic document conveying device for use with an image processing machine having a transparent plate on which to place documents. The device includes an opening-closing frame and a document table. A conveyor roller means is rotatably mounted in the opening-closing frame. It also includes a document delivery means for delivering sheet-like documents from the document table. The document delivered from the document table is introduced into a required position on the transparent plate by the conveyor roller means. The rotation of the conveyor roller means in the introducing direction is stopped while the introduced document is still nipped between the conveyor roller means and the transparent plate. A guiding means which permits advance of the document from the document table to the transparent plate but hampers movement of the document from the transparent plate toward the document table and deflects it upwardly is provided between the document table and the conveyor roller means. When the conveyor roller means is rotated in the carrying direction, the document on the transparent plate is deflected upwardly by the guiding means and discharged through a discharge opening formed in the opening-closing frame.

Abstract: This invention provides an optical head apparatus in which a grating coupler (8), which is formed on a circular region which has a center on an axis (18) and has a periodical structure with dents and projections in a configuration of concentric circles or spirals around the axis (18), input-couples laser light (7) emitted from a semiconductor laser (5) and turns it into waveguided light (16B) which transmits in waveguiding layer (15B). The waveguided light (16B) is converted, in a region where the waveguiding layer (15B) and a waveguiding layer (15A) overlap each other, to waveguided light (16A) which transmits in the waveguided layer (15A). By a grating coupler (9), formed on a ring-shaped area which is located around the axis (18), which has a periodic structure with dents and projections of a configuration of concentric circles or spirals around the axis (18), the waveguided light (16A) is radiated and focused onto points (FA), (FB) and (FC) which are located on the axis (18). Light reflected from a reflecting surface (19) is input-coupled by the grating coupler (9) and is converted to waveguided light (21) which transmits through the waveguiding layer (15A) toward the center. The waveguided light (21) is radiated at the innermost edge of the waveguiding layer (15A) and the amount of radiated light is detected by a light detector (10) to obtained control signal and playback signals.

Filed: 1989-06-15
Abstract: A system for mapping rules and objects from a database system (10) during an inference cycle includes a database system (10), a knowledge request translator (14), and an inference system (16, 17). The database system (10) stores both the facts (12) and rules (11). The knowledge request translator (14), in response to rule retrieval requests (15), retrieves rules from the database system, each rule retrieval being based on rule selection criteria that are included in the rule request. The inference system (16, 17) generates rule retrieval requests, including rule selection criteria, for use by the knowledge request translator (14). The inference system (16, 17) initiates inference operations in connection with rules (11) retrieved by said knowledge request translator (14), and facts (12) in the database system. In initiating inference operations, the inference system (16, 17) supplies fact criteria to the knowledge request translator (14), which generates, in response thereto, database inquiries to initiate existence tests in connection with the facts (12) in the database system (10). The results of the existence tests are used in connection with subsequent processing during the inference operations.
