Title: Time-of-flight bacteria analyser using metastable source ionization
Inventor: BERTRAND MICHEL J
IPC: H01J49/16
Filed: 2001-11-27
Abstract: For analyzing micro-organisms and other high-molecular weight species, a sample of the substance to be analyzed is prepared, placed in a pyrolyzer where it is pyrolyzed with a selected temperature program to provide pyrolyzed product of a high-dalton mass range. The product is ionized using metastable atoms which results in efficient ionization with little fragmentation. The metastable atoms are generated using a generator that provides a beam of metastable atoms which is basically free from ions. The ionized product is then analyzed using a high acquisition rate mass analyzer, such as a time-of- flight (TOF) analyzer.

Patent CA-2433076-A1 (CA)
Inventor: DROUIN DOMINIQUE
IPC: B81C1/00
Filed: 2001-02-05
Abstract: L'invention concerne un procédé de lithographie permettant de fabriquer des structures d'un composé métallique-semi-conducteur résistant à l'attaque chimique placées sur un substrat ayant des résolutions à l'échelle sub-micrométrique. On procède, à cet effet, au dépôt de couches superposées de métal et semi-conducteur capables de réagir entre elles afin d'obtenir un composé métallique/semi-conducteur résistant à l'attaque chimique. Un rayonnement provenant d'une source de rayons X/ultraviolets extrêmes se propage à travers un masque réfléchissant à motifs à rayons X transparents/ultraviolets extrêmes et est projeté sur les couches superposées de métal et semi-conducteur. Le masque transparent de rayons X comprend des motifs d'absorption de rayons X imprimés sur les rayons X, alors que le masque réfléchissant d'ultraviolets extrêmes comprend des motifs d'absorption d'ultraviolets extrêmes imprimés sur le rayonnement d'ultraviolets extrêmes. L'énergie des photons de rayons X/ultraviolets extrêmes est absorbé localement par les couches de métal et semi-conducteur. L'absorption de cette énergie provoque une réaction entre les deux couches responsables de la formation du composé métallique/semi-conducteur résistant à l'attaque chimique dont les structures correspondent aux motifs imprimés sur le rayonnement par le masque de rayons X/ultraviolets extrêmes. La couche métallique est gravée par la suite à l'aide d'une technique de gravure par plasma ou humide sélective, laissant ainsi les structures de composé métallique/semi-conducteur résistant à l'attaque chimique intactes.

Abstract: A corrugated heat exchanger element (30) may have grooves (36) and ribs (38) on the interior and exterior surfaces of the tube. The corrugations on the tube may be linear corrugations or helical corrugations. The texturing of the interior and exterior surfaces (32, 34) of the tube, and the corrugations in the tube may provide a heat exchanger element (30) that has a large surface area. The surface texturing and corrugations may also provide a heat exchanger element that promotes internal mixing of fluids that flow by and through the element. Increased internal mixing and increased surface area of an element may allow the heat exchanger element to have a high heat transfer coefficient. A heat exchanger element (30) or heat exchanger elements may be assembled into a heat exchanger that has a high overall heat transfer coefficient. Ends of the heat exchanger element may be pointed to focilitate attachment of the element to a support structure.
