Patent EP-0879834-A1 (EP)
Inventor: TANG HONG WONG
IPC: C08F4/70
Filed: 1998-05-14
Abstract: Syndiotactic 1,2-polybutadiene is a thermoplastic
resin which has double bonds attached in an
alternating fashion to its polymeric backbone. Films,
fibers and molded articles can be made utilizing
syndiotactic 1,2-polybutadiene. It can also be
blended into rubbers and cocured therewith. It is
generally preferred to synthesize syndiotactic 1,2-polybutadiene
in an aqueous medium by suspension or
emulsion polymerization. In such aqueous
polymerization techniques reactor fouling and particle
size control problems are frequently encountered.
This invention is based upon the unexpected finding
that reactor fouling can be greatly reduced or
eliminated and that particle size can be regulated by
conducting such aqueous polymerizations in the
presence of a controlled amount of dissolved oxygen
which is within the range of about 0.01 ppm to about 4
ppm. This invention more specifically discloses a
process for preparing syndiotactic 1,2-polybutadiene
in an aqueous medium with minimal reactor fouling
which comprises polymerizing 1,3-butadiene monomer in
the aqueous medium in the presence of (1) a catalyst
system which is comprised of (a) transition metal
compound, (b) an organoaluminum compound and (c) at
least one member selected from the group consisting of
carbon disulfide, phenyl isothiocyanate and xanthic
acid and (2) from about 0.01 ppm to about 4 ppm of
oxygen.

Abstract: A method for producing a NOx sensor comprises the steps
of forming electrodes (24, 40, 50) on ceramic green sheets,
and stacking and integrating the ceramic green sheets into
one unit followed by sintering to prepare a substrate (300),
wherein an oxygen concentration is controlled to be not more
than 0.5 % in a sintering atmosphere after removal of a
binder in the step of sintering the substrate (300).
Specifically, the sintering is performed in an atmospheric
atmosphere in Interval 1 in which the temperature in a
furnace is changed from room temperature to about 1000 °C,
and the sintering is performed in a nitrogen atmosphere
(oxygen concentration in the atmosphere in the furnace is
controlled to be about 400 ppm) in Interval 2 in which the
temperature is changed from 1000 °C to a maximum temperature
followed by spontaneous radiational cooling. Accordingly,
it is possible to suppress alloy formation on a detecting
electrode (40) for detecting a measurement gas component
(for example, NOx), and it is possible to improve the
measurement accuracy of the NOx sensor.

Abstract: A method for reducing hot carrier reliability problems within an integrated
circuit device. The method includes forming a shallow trench isolation structure
incorporated with the device by filling a trench with a photoresist plug and
removing a portion of the photoresist plug to a level below the depth of a channel
also incorporated with the device. A nitride liner disposed within the trench under
the photoresist plug is then recessed to a level substantially equal to the level of the
photoresist material, which is then removed. The method further includes the
deposition of oxide fill within the trench, thereby encapsulating the recessed nitride
liner.

Abstract: The low pass filter for use in the UV spectrum comprises a dielectric stack which ensures an anti-reflective function for wavelengths ( lambda ) greater than a critical value ( lambda  c). The critical value is less than 300 nm. Beneath these layers there is a metal base layer ensuring a reflection function for wavelengths greater than the critical value of wavelength ( lambda c). The combination formed in this way does not require a very thick dielectric stack - a thickness between a hundred nanometres and several micrometres if sufficient. The metal forming the base may be an alkali metal, or an alkali earth, so that the cut-off wavelength lies within the UV spectrum. One or more layers of material having the required anti-reflective properties may be used, and the layers may alternate with two different materials.

Abstract: La présente invention concerne des procédés et des systèmes de pilotage de pompe de charge qui forcent une pompe de charge d'un filtre en boucle PLL à charger ou décharger un condensateur pendant un temps défini indépendant du signal d'erreur du détecteur de phase. Puis la pompe de charge est activée en réaction à un signal d'erreur du détecteur de phase. Au lieu de compter sur le signal d'erreur pour activer une pompe de charge, cette pompe de charge peut être activée pendant une durée qui ajoutera ou supprimera une quantité requise de charge au filtre à boucle. On peut ainsi diminuer les temps de verrouillage tout en réduisant les dimensions et le prix de la pompe de charge. Cette invention s'applique de préférence à une pompe de charge intégrée dans une boucle PLL.
