Title: Dispositif d'alimentation en energie pour endoscope
Inventor: YAMAMOTO HIDEHIRO
IPC: A61B18/14
Filed: 1999-09-17
Granted: 2007-08-28
Abstract: Dans ce dispositif d'alimentation en énergie pour endoscope, qui comprend une unité d'exploitation, un cylindre et une électrode, vient s'insérer un endoscope. Le cylindre porte, sur son extrémité distale, l'électrode et, sur l'autre extrémité, l'unité d'exploitation. L'objectif de l'endoscope introduit dans ce dispositif d'alimentation fait saillie de l'extrémité distale dudit dispositif, l'endoscope pouvant coulisser axialement dans celui-ci. Ce dispositif que l'on peut avantageusement utiliser pour un intervention endoscopique, notamment pour congeler un vaisseau sanguin, se révèle particulièrement utile dans le cas d'une anesthésie du système sympathique de la partie inférieure du thorax; il permet alors de pratiquer l'intervention avec une incision cutanée aux dimensions minimales. Dans la mesure où il n'est pas nécessaire d'introduire ce dispositif dans le corps du patient lors d'une intervention, ni de l'en extraire, le frottement et le stimulus exercés sur la région incisée se trouvent réduits, ce qui diminue les risques de dommages infligés à la région incisée, et permet au patient, de ce fait, de quitter l'hôpital et de rentrer chez lui le jour même de l'opération.

Abstract: An arbor for a guided circular saw has three symmetrical lobes. The lobes have end regions with profiles which follow an arc centred on an axis of rotation of the arbor. The lobes have driving regions with profiles which follow the arc of a circle centred in an opposing lobe. A saw for use with the arbor has an eye with a shape which follows the contour of the arbor. The saw is capable of floating axially along the arbor. The saw and arbor can be used to advantage in sawing machines such as edgers. The arbor provides a much larger saw contact area than do prior art arbors. In one embodiment of the invention the saw is mounted between a pair of spaced apart collars on the arbor. The collars guide the saw but are not tightly clamped to the saw.

Abstract: Through the Internet, it is possible to electronically link documents, by embedding hyperlinks into documents. The hyperlinks, which function as network addresses for specific documents, can be selected to "jump" electronically from a document on one computer system to a document on another computer system. One problem with conventional hyperlinks is that occasionally they become out dated and ineffective, as documents are deleted, for example.  Another problem is that hyperlinks are typically generated without regard to connection time or charges involved in accessing specific computers, leading users to waste time or incur unnecessary charges when hyperlinking.  Accordingly, the inventors devised a system, method, and software that automatically locate and mark specific portions of a document and define hyperlinks including at least a portion of the marked text. An exemplary implementation, tailored for legal citations, processes the portion of the marked text as a search term, and allows completion of hyperlinks without the necessity of including complete file addresses. This implementation also defines a portion of the hyperlinks based on the cost or time of executing the hyperlink, to reduce the cost or time of executing the hyperlink.

Abstract: A hydrogen sensor includes a first electrode and a second electrode provided in contact with a proton conduction layer; a gas diffusion controlling portion provided between a measurement gas atmosphere and the first electrode; and a support element for supporting the proton conduction layer, the first electrode, the second electrode, and the gas diffusion controlling portion. Hydrogen contained in a measurement gas introduced via the gas diffusion controlling portion is dissociated, decomposed, or reacted by applying a voltage between the first electrode and the second electrode to thereby generate protons. Hydrogen concentration is obtained on the basis of a limiting current generated as a result of the generated protons being pumped out via the proton conduction layer from the first electrode side of the proton conduction layer to the second electrode side of the proton conduction layer. Hydrogen concentration on the first electrode is controlled to a partial pressure of not less than 10 -12 atm, or more preferably, of not less than 3 × 10 -12 atm.
