Patent EP-1043281-A1 (EP)
Inventor: TANKALA KANISHA
IPC: C03B37/018
Filed: 2000-04-07
Abstract: The present invention discloses a method of fabricating rare earth-doped
preforms for optical fibers. A silica soot is deposited as a layer with high porosity on an
inner surface of a silica-based tube by a modified chemical vapor deposition (MCVD)
process at a temperature high enough to produce the silica soot but low enough to avoid
sintering of the soot into the silica-based tube. The silica-based tube is then immersed in
a solution including a rare earth element and optionally a codopant element for impregnation. The
excess solution is drained and the silica-based tube is dried in a stream of chlorine and
inert gas at an elevated temperature. Then, the rare earth element and the optional codopant
element are oxidized under an oxygen partial pressure at a temperature high enough to
overcome kinetic limitations against oxidation. Finally, the soot layer is consolidated
while flowing oxygen and optionally a mixture of chlorides of a second codopant element
at a sintering temperature at which the second codopant element reacts with oxygen to form
codopant oxide which is delivered around the rare earth element oxide deposited in the
soot layer. In the method of the current invention, one or more rare earth elements are
codoped with preferred codopants including but not limited to Ge, Al, P and/or B to
enhance the performance of the rare earth ions. Other dopants may also be used in
conjunction with the preferred dopants for modifying the refractive index of the core.

Abstract: An aqueous dispersion comprising a copolymer which is the polymerization
product of a mixture of vinylic monomers wherein from about 5% to about 90% by
weight of the vinylic monomers are selected from co-esters of a drying oil acid and an
unsaturated α, β-polymerizable unsaturated carboxylic acid, contains from about 0.5%
to about 50% by weight based on the weight of the copolymer of a hydrophobic ester or
partial ester of a drying oil acid and a polyol. The copolymer polymerized in the
presence of the hydrophobic ester or partial ester is characterized by a relatively low gel
content, and by a relatively broad, multi-nodal, molecular weight distribution, including
a low molecular weight component which acts as a transient plasticizer and coalescing
agent. The aqueous dispersions can be formulated into quick drying coating
compositions which form smooth protective films on various substrates, without
requiring volatile coalescing agents.

Abstract: An optical fiber filter is produced which has a sinusoidal response or a modulated sinusoidal response with any desired amplitude and wavelength period. This is achieved by first producing an elongated adiabatic taper in a single-mode fiber which has been stripped of its protective jacket. Then, on the slope of this adiabatic taper, at each end of the central zone, there is formed a non-adiabatic taper such as to obtain a predetermined sinusoidal or modulated sinusoidal response in the filter.

Abstract: L'invention concerne un circuit de calage de résistance-condensateur-diode couplé à une capacité S d'un étage de sortie d'un circuit de déviation horizontale permettant de réduire les oscillations de dépassement en provoquant un amortissement critique. La tension d'alimentation de l'étage de sortie varie de matière parabolique et verticale pour moduler le courant de déviation horizontale et assurer une correction Est-Ouest. Un condensateur à circuit de calage comporte une borne qui est couplée en courant continu à la tension d'alimentation. Par conséquent, chaque borne du condensateur présente la même composante de parabole à vitesse verticale. De ce fait, la différence de tension en courant continu générée entre les bornes du condensateur ne comprend aucune composante de parabole verticale. Ainsi, la sensibilité de l'amortissement aux variations de la tension d'alimentation à vitesse verticale est supprimée ou réduite de manière avantageuse.

Abstract: An optical sensor architecture receives an input optical signal (502) from a signal source (500) and outputs a perturbed optical signal (510) from at least one sensor (508) to a receiver (520). An optical amplifier (516) is positioned along a return fiber (512) at an optical distance at least 10 kilometers from the receiver (520), with the optical amplifier (516) amplifying the perturbed optical signal (510) propagating to the receiver (520). If only one optical amplifier (516) is used, the optical distance between the amplifier (516) and the receiver (520) may be between about 10 km and about 80 km, and an optical distance of between about 10 km and about 150 km may separate the sensor (508) and the receiver (520). If additional optical amplifiers (544) and dedicated pump distribution fibers (540, 552) are used, the optical distances may be correspondingly greater. Alternatively, increasing the number of sensors (508) necessitates a reduction in the optical distance separating the sensors from shore.

Abstract: The invention relates to an integrated circuit and to a method for determining the current yield of a part of the integrated circuit. According to the invention, the current yield of at least one circuit part (ST) of the integrated circuit (IS) is determined by measuring the current yield of a current source (T1, T2, T3, T4) which is arranged on an input terminal (EA1, EA2) or output terminal (AA1), whose current yield is proportionate, in a defined manner, to a number of reference current sources (REF0...REF7) which are located inside the circuit and which have different current yields, and whose current yield is compared with that of the circuit part (ST) to be measured. By knowing which of the internal reference current sources (REF0...REF7) have a higher and which have a lower current yield than that of the circuit part (ST) to be measured, and by knowing the current yield of the current sources (T1, T2, T3, T4) arranged on an input terminal (EA1, EA2) or output terminal (AA1) as well as by knowing the proportion of the current yields, the current yield of the circuit part (ST) can be measured without directly accessing the integrated circuit (IS) from outside.

Abstract: The invention aims to compensate for tolerances which occur in the interior construction of rail vehicles, using a floating floor construction and to allow a force-reducing relative displacement between the installation components which are permanently mounted onto the construction shell, such as seats, back panels, cupboards etc. and the floor, whilst excluding the penetration of moisture between the permanently mounted attachments or installed sections and the floor, which can be displaced in relation to each other. This is achieved by a corner profile (12), located between the floor plate (5) and the attachments or installed sections (18) that are permanently mounted onto the construction shell. Said corner profile runs both longitudinally and transversally in relation to said attachments and sections, forming a bearing surface (11) for the floor covering. One limb (13) of said corner profile forms the edge of the floor plate (5) which is to receive the floor covering and the other limb (15) is positioned so that it can be displaced in a longitudinal and transverse direction, in relation to the construction shell. The horizontal tolerance compensation can be absorbed by a flexible seal (17) which is fixed to the limb (15) and lies against the construction shell.
