Abstract: L'invention se rapporte à un amplificateur optique présentant un profil de gain sensiblement plat et indépendant, sur un domaine étendu, de la puissance de la pompe, de la puissance des signaux d'entrée et du nombre de ces signaux. Cet amplificateur met en oeuvre un résonateur optique possédant un milieu à gain dans lequel l'accroissement du gain se produit de manière non homogène par pompage du milieu à gain pour au moins une longueur d'onde dans au moins une queue d'absorption du milieu à gain. Le résonateur est un résonateur en anneau qui comporte de préférence une fibre dopée à l'erbium. Il est possible d'ajouter des co-dopants à la fibre afin de renforcer l'effet d'accroissement non homogène. L'invention concerne également un procédé d'égalisation du gain qui consiste à introduire un signal de pompe dans un milieu à gain. Une pluralité de signaux optiques à différentes longueurs d'ondes sont introduits dans le milieu à gain. L'émission stimulée au sein du milieu à gain bloque le gain dudit milieu.

Title: Prosthetic heart valve
Inventor: MYERS KEITH
IPC: A61F2/24
Filed: 2001-01-29
Granted: 2011-01-04
Abstract: A tubular prosthetic semilunar or atrioventricular heart valve is formed by cutting flat, flexible leaflets according to a pattern. The valve is constructed by aligning the side edges of adjacent leaflets so that the leaflet inner faces engage each other, and then suturing the leaflets together with successive stitches along a fold line adjacent the side edges. The stitches are placed successively from a proximal in-flow end of each leaflet toward a distal out-flow end. During operation, when the leaflets open and close, the leaflets fold along the fold line. Distal tabs extend beyond the distal end of each leaflet. The successive stitches terminate proximal of the distal tab portion so that no locked stitches are placed along the distal portion of the fold line. The tab portions of adjacent leaflets are folded over each other and sewn together to form commissural attachment tabs. The commissural tabs provide commissural attachment points to accommodate sutures and the like in order to secure the tab to a vessel wall, if a semilunar valve, and papillary muscles and/or chordae tendineae if an atrioventricular valve.

Title: Method and apparatus for recording address information on disc medium
Inventor: KOBAYASHI SHOEI
IPC: G11B7/26
Filed: 2002-03-19
Granted: 2013-04-16
Abstract: In step S1, an address generation block generates and pre-encodes a synchronization signal, address data, and address information composed of an error correction code of the address data which are to be recorded on an optical disc and outputs them to a modulation block. Simultaneously with this, a carrier signal generation block generates a carrier signal for carrying the address information and outputs it to the modulation block. In step 2, the modulation block MSK-modulates the carrier signal input from the carrier signal generation block with the pre-encoded address information input from the address generation block and the obtained MSK-modulated signal is output to a wobble formation block. In step S3, the wobble formation block forms on the optical disc a spiral groove wobbled in accordance with the MSK-modulated signal input from the modulation block. On this optical disc, an arbitrary address can be accessed rapidly.

Abstract: L'invention concerne un palier hydrodynamique sensible à une charge, présenté sous la forme d'un palier de butée ou d'un palier d'un tourbillon, destiné à supporter, guider et lubrifier un élément entraîné en rotation relative, en vue de minimiser l'usure de celui-ci, en réponse à la rotation relative sous des charges sévères. Dans l'espace situé entre des éléments espacés entraînés en rotation relative et en présence d'un lubrifiant sous forme de liquide ou de graisse, un ou plusieurs corps de palier de forme d'anneau continu, monobloc et de forme générale circulaire définissent au moins une surface dynamique et une pluralité de régions support. Chacune de ces régions définit une surface statique orientée dans une relation généralement opposée avec la surface dynamique, de manière à être en contact avec un des éléments entraînés en rotation relative. Plusieurs régions soumises à la flexion sont définies par le corps de forme générale circulaire du palier et sont d'une seule pièce avec des régions support adjacentes et sont situées entre celles-ci. Chaque région soumise à la flexion comprend un premier élément de type faisceau étant connecté au moyen d'une articulation intégrée souple avec une des régions support et un second élément du type faisceau présentant une connexion à articulation intégrée souple avec une région support adjacente. Au moins une géométrie locale d'affaiblissement de la région soumise à la flexion est située au milieu des premier et second éléments de type faisceau. En réponse à l'application d'une charge à partir d'un des éléments entraînés en rotation relative par rapport au palier, les éléments de type faisceau et la géométrie locale d'affaiblissement deviennent fléchis, entraînant la déformation de la surface dynamique et l'établissement d'une géométrie hydrodynamique destinée à la lubrification en coins dans l'interface dynamique.
