摘要:
The three-layer magnetic element of the present invention comprises, on a substrate, a first hydride-oxide or nitride-oxide layer O having a metal magnetic layer M mounted thereon, the latter having either a second hydride-oxide or nitride-oxide layer O’, or a non-ferromagnetic metal layer M', mounted thereon. The layer M is continuous, has a thickness of 1 to 5 nm, and has the magnetization thereof parallel to the layer plane in the absence of layers O and O’. There is, for a range of temperature equal to or greater than room temperature, an interfacial magnetic isotropy perpendicular to the layer plane on the interfaces O/M and M/O' that is capable of decreasing the actual demagnetizing field of the layer M or orienting the magnetization of the layer M in a manner substantially perpendicular to the layer plane.

摘要:
An energy source of a thermal tissue operating system performs self-tests using simulation heating elements and jaw heating elements in tissue-grasping jaws of a handpiece. Power is supplied to the simulation heating elements and verified, without necessitating connection of a handpiece. Power is also delivered and verified to each of the two jaw heating elements when the handpiece is connected. Voltage and current are measured by peak hold detectors, and the peak hold detectors are tested to verify correct operation. All tests may be combined in a power on self-test (POST).

Cet escalier préfabriqué en béton est constitué d'au moins une crémaillère sur laquelle est agencé au moins un élément de marche (1, 2) comprenant au moins une marche une contremarche. La crémaillère et l'élément de marche définissent une cavité linéaire et continue destinée à recevoir un ferraillage (5) de renfort mécanique, puis à être remplie de béton. Elle se présente sous la forme d'éléments individualisés (3, 4) constitués chacun de deux parties latérales reliées entre elles par une partie inférieure, au moins une partie latérale de ces éléments individualisés étant conformée de manière à recevoir une marche et une contremarche (1, 2).
摘要:
A segmented track made of a plurality of elastomeric track segments is provided. Each track segment is made of reinforced elastomeric material and is provided, at each end thereof, with a joint element adapted to be connected to the joint element of adjacent track segments. Each track segment comprises longitudinally extending reinforcing elements which are embedded into the elastomeric material and which are extending between and coupled to both joint elements.

The photodiode of the invention includes a stack of three layers including an intermediate layer (2) provided between first and second layers (1, 3) of semiconductors having a first type of conductivity, and a region (4) in contact with at least the intermediate layer (2) and the second layer (3) and extending transversally relative to the planes of the three layers (1, 2, 3), said region (4) having a second type of conductivity the opposite of the first type of conductivity. The intermediate layer (2) is made of a semiconducting material having the second type of conductivity, an inversion of the type of conductivity of the intermediate layer (2) from the second type of conductivity to the first type of conductivity being induced by the dopants of the first type of conductivity in the first and second layers (1, 3) so as to form a P-N junction with said region (4).
摘要:
This radiator for domestic heating with a heat-transfer fluid operating in two-phase form comprises: a reservoir (3) of said heat-transfer fluid; a hot source (6), intended to raise the temperature of said heat-transfer fluid to a temperature such that it causes said fluid to undergo a change of phase; a heater, at which the heat transfer with the ambient air takes place, having n channels (4), communicating in a lower zone with the reservoir (3), it being possible for n to be equal to 1. According to the invention, the heat-transfer fluid is a mixture of at least two different heat-transfer liquids, the heat-transfer liquids having between them boiling points differing by at least ten degrees Celsius, and the liquid with the lowest boiling point representing 70% to 95% of the volume of the mixture for a mixture temperature of about 200°C.
