Abstract: La durabilité de bougies de réchauffage classiques est extrêmement courte lorsqu'elles sont continuellement excitées à une température élevée au cours du fonctionnement du moteur afin d'aider à l'allumage des carburants non-auto-allumants. De telles bougies de réchauffage défaillent typiquement en raison de contraintes thermiques et/ou l'oxydation et la corrosion. On décrit ici un ensemble élément de chauffage amélioré (10, 10', 10'') conçu pour être incorporé dans une bougie de réchauffage. L'ensemble élément de chauffage (10, 10', 10'') comprend une gaine monolithe (24) pourvue d'une paroi relativement mince et généralement annulaire qui définit une cavité borgne (34). L'ensemble élément de chauffage (10) comprend en outre un dispositif chauffant (26, 26', 26'') situé dans la caivité borgne (34) et conçue pour émettre de la chaleur, et un dispositif de transfert de chaleur (28) conçu pour transférer la chaleur de l'élément de chauffage (26, 26', 26'') à la gaine (24). Le dispositif chauffant (26, 26', 26'') est protégé par la gaine (24), qui est fabriquée à partir d'un matériau présélectionné, choisi et formé de manière à réduire au minimum la possibilité de défaillance de l'ensemble élément de chauffage (10, 10', 10'') due aux contraintes thermiques, à l'oxydation et/ou la corrosion.

Abstract: A superlattice superconductor structure is provided in which a phonon generator (10) embedded in a quantum well (18) promotes formation of paired electrons. The superlattice structure provides electrons confined in a narrow energy gap material (11, 12) which is sandwiched between two barrier layers (13a, 13b, 14a, 14b) made of larger bandgap material. The electrons are provided to the quantum well by doping material (21, 22) in the barrier layers (13a, 13b, 14a, 14b) to provide modulation doping of the quantum well (18). The quantum well contains at least one monolayer (10) of another material within its boundaries which is a source of phonons which are generated for the purpose of electron-phonon coupling in order to cause electron pairing. In a preferred embodiment a plurality of phonon generator monolayers (10) will be provided in the center of a quantum well, wherein the phonon generator monolayers (10) are separated from each other by a few monolayers of quantum well material (16) to provide increased number of phonons and therefore increased number of electron-phonon interactions.
