Abstract: Une source de rayonnement (12) pour magnotomètres optiques (10) utilisant des isotopes d'hélium comme élément de résonnance (30) comprend un laser (12) à semi-conducteur pompé électroniquement, lequel produit une seule ligne étroite de rayonnement stabilisée en fréquence sur la fréquence centrale de la ligne de résonnance de l'hélium à pomper optiquement. La stabilisation en fréquence est accomplie à l'aide d'une rétroaction électronique (34, 40, 42, 44), permettant de réguler une source de courant (20), éliminant ainsi la nécessité d'une synthonisation de fréquences mécaniques.

Abstract: Système à actionnement par fluide primaire et à propulsion de fluide secondaire qui peut être utilisé, par exemple, en tant que dispositif pour coeur artificiel implantable, comprenant une pompe unidirectionnelle pour pomper le fluide électrorhéologique, deux conduites de retour en boucle reliées à la pompe et pour chaque conduite de retour, deux valves électrorhéologiques placées à l'intérieur desdites conduites en débit de série, et un dispositif à actionnement par fluide primaire et à propulsion de fluide secondaire relié à cette boucle en un endroit situé entre les deux valves électrorhéologiques. Les dispositifs à actionnement par fluide primaire et à propulsion de fluide secondaire peuvent comprendre une chambre dont l'intérieur est divisé par un diaphragme souple transmettant la pression en une première cavité destinée à recevoir le fluide électrorhéologique de cette boucle de retour et une seconde cavité destinée à propulser le fluide secondaire. Les valves électrorhéologiques sont actionnées pour pressuriser une première cavité tout en vidant l'autre et vice versa. Dans la version de la présente invention destinée aux pompes de soutien cardiaque, le dispositif à actionnement par fluide primaire et à propulsion du fluide secondaire est remplacé, par exemple, par un conteneur flexible, placé à l'intérieur de la cavité corporelle, dont le fonctionnement permet de transmettre la pression du fluide à l'intérieur de la cavité.

Abstract: A liquid cooling apparatus includes a heat exchanger, a tank, leakage sensors, first and second level sensors, a timer counter, and a control section. The heat exchanger cools a coolant to be supplied to a heat generating portion in an electronic device. The tank temporarily stores the coolant cooled by the heat exchanger before the coolant is supplied to the electronic device. The leakage sensors detect leakage of the coolant in a circulation path for repeatedly performing cooling and heat absorbing operations. The first and second level sensors detect a decrease in amount of the coolant in the tank. The timer counter counts a time interval between the instant at which a leakage detection output is output from one of the leakage sensors and the instant at which a coolant decrease detection output is output from one of the first and second level sensors. The control section stops an operation of the electronic device when a value of the timer counter is a predetermined value or less.

Abstract: A variable speed transmission (1) is disclosed which has a torque converter (6) at the input of both a fixed transmission (4) which is used for low vehicle speeds and a variable transmission (5) which is used for medium and high vehicle speeds. The variable transmission (5) has a variator (11) which may be of the belt and pulley, hydraulic or electric types. The variable transmission (5) is more efficient than heretofore because power is split within the variable transmission (5) by a power split differential (9) between the variator (11) and a main power output shaft (3). Thus, the variator (11) is only called upon to handle a portion of the power when the variable transmission (5) is in operation. Thus, power losses in the variator (11) are substantially reduced.

Abstract: Disclosed are an aluminum alloy casting having a high strength and a high toughness, and a production process for the same. The aluminum alloy casting comprises silicon (Si) in an amount of 2.5 to 4.4% by weight, copper (Cu) in an amount of 1.5 to 2.5% by weight, magnesium (Mg) in an amount of 0.2 to 0.5% by weight and the balance of aluminum (Al), and a matrix thereof includes a dendrite which has a size of 30 micrometers or less. Since the Si addition amount is suppressed as less as possible and since the size of the dendrite is micro-fined in the aluminum alloy casting, the toughness is improved remarkably. Further, since the Cu and Mg are added in the predetermined addition amounts, the strength is enhanced in the aluminum alloy casting. In addition, a solution treatment which is employed in the production process can further enhance the strength of the aluminum alloy casting.
