Filed: 1997-03-21
Abstract: A process of producing molten iron involves: a) introducing iron oxide, flux, oxygen, nitrogen, carbon, and hydrogen to a smelter reactor; b) maintaining conditions to cause (i) the iron oxide to be reduced, (ii) molten iron to be created and stirred in the bottom of the reactor, surmounted by a layer of foaming, FeO-containing slag, and (iii) carbon monoxide gas to rise through the slag; c) causing at least some of the carbon monoxide to react with the oxygen; d) releasing an offgas containing CO, CO2, H2 and H2O; and e) removing at least some of the molten iron and slag from the reactor. Good process stability is achieved by: f) repeatedly measuring, during the process, the conditions of the slag height, the temperature of the molten iron, the levels of CO, CO2, H2, and H2O in the offgas, the carbon level in the molten iron, and the FeO level in the slag, and g) subsequently adjusting one or more process variables (e.g., a reactant feed rate, the iron bath stirring rate, or the height of the oxygen lance above the slag) so as to help keep one or more of those process conditions within a predetermined range.

Title: Method and anastomotic instrument for use when performing an end-to-side anastomosis
Inventor: RYGAARD JORGEN A
IPC: A61B17/11
Filed: 1996-04-30
Abstract: In a method of establishing an end-to-side anastomosis by using an instrument (501) with a passage (502D) for a bypass vessel, terminated by a circumferential anvil (502A, 503B), about which the end of the bypass vessel may be everted and then inserted through an anastomosis opening in a second vessel, such as a coronary artery, after which the tissue edges to be joined are first clamped together by clamping slides (505) and then stapled together by stapling plungers (506) so as to interconnect the two vessels, the main novel feature is that the stapling plungers (506) are arranged to move at an angle to the passage (502D) instead of parallel to it. With this arrangement, it is possible to use a greater number of staples than has been possible in previous related methods. Preferably also, the instrument is adapted to be divided lengthwise of the passage (502D).

In such a case, the degree to which the space between the rotor (3) and the stator (1, 2) is filled and the amount of the heat generated by the friction can be regulated. Further, the ratio of the material flows in the different supply conduits (6, 7) determines the ratio of the thicknesses of the layers obtained. Therefore, the method and apparatus according to the invention make it possible to regulate the properties of the final product easily and in several different ways.

IPC: G11B5/012
Filed: 1997-04-15
Abstract: L'invention concerne des jonctions composées de trois couches, une couche ferromagnétique, une couche isolante et une autre couche ferromagnétique. Ces jonctions présentent des effets de magnétorésistance allant d'environ 16 % à plusieurs centaines de pour-cent à température ambiante. Des effets accrus sont observés lorsque la résistance à l'effet tunnel (R¿T?) effective est comparable à la résistance du film électrode (R¿L?) sur la zone jonction dans des segments de jonction de section transversale. La magnétorésistance accrue géométriquement peut être expliquée quantitativement par la présence de courant non uniforme sur la zone de jonction quand R¿T? est comparable à R¿L?, dans le segment de section transversale. Pour une zone de jonction fixe, la résistance de jonction (R¿J?) effective peut être modifiée de moins de 1 ohm à plusieurs kilo-ohms par variation de l'épaisseur de la couche isolante ou par sélection de manière appropriée de couches ferromagnétiques. Les jonctions tunnel à trois couches de la présente invention sont non volatiles, stables et reproductibles.

Title: Method for growing plants and apparatus for growing plants
Inventor: TAKAYANAGI EIFU
IPC: A01G31/02
Filed: 1998-06-05
Abstract: Disclosed are a plant cultivation apparatus and a plant cultivation method. The method employs an artificial light efficiently for cultivating the plant while oxygen necessary for growing a plant root can be supplied sufficiently and growth of bacteria can be prevented. Heat damage such as a chip-burn may be prevented by minimizing heat generated by the artificial light (fluorescent light).      In the method, the plant root is bathed in a cultivation water solution containing fertilizer and air having high concentration of carbon dioxide may be blown into the cultivation water solution intermittently during a plant cultivation term. All inside walls of a cultivation room may be covered with a light reflection layer. Additionally, the output of the fluorescent light may be controlled to 30 to 70 % of a rated specification. As a result, the plant can be cultivated with a minimum quantity of light.
