Inventor: PRENTICE SUSAN MONET
IPC: C08F279/02
Filed: 1992-10-14
Abstract: The present invention relates to a free radical emulsion polymerization process. The latex is prepared by polymerizing (a) at least one conjugated diene, (b) at least one non-carboxylic vinyl aromatic or aliphatic comonomer selected from the group consisting of styrene, α-methyl styrene, p-methyl styrene, vinyl toluene, acrylonitrile, methacrylonitrile, vinylidene chloride, ethyl acrylate, butyl acrylate, vinyl pyridine, methylmethacrylate, hexylacrylate, 2-ethyl hexyl acrylate or mixtures thereof, and (c) at least one ethylenically unsaturated carboxylic acid monomer selected from the group consisting of acrylic acid, methacrylic acid, maleic acid, fumaric acid, 3-carboxyethylacrylate, itaconic acid or mixtures thereof. The process of the present invention is characterized by (a) initially polymerizing the non-carboxylic comonomer in the presence of the unsaturated carboxylic acid and in the absence of any conjugated diene to a conversion of 3 to 12 percent to form a partially polymerized latex; and thereafter (b) copolymerizing the conjugated diene with the unreacted non-carboxylic comonomer in the partially polymerized latex. The present process mitigates the formation of codimers of the conjugated diene and non-carboxylic comonomer. The present process also provides a latex having unique film forming characteristics and polymer morphology leading to unique film stiffness and stress-strain relationship.

Abstract: The invention relates to a circuit arrangement for determining the total charge generated by a single event in a semiconductor radiation detector. The signals from the charge-sensitive preamplifier with RC feedback, following the detector, are processed digitally in this arrangement. The final results, the total charge quantity released in the semiconductor detector by means of a single quantum of radiation, is obtained, according to the invention, from the difference of two values. The first value is obtained from L results of a numeric deconvolution of the charge distribution function of the radiation result, convoluted with the preamplifier transfer function, which, as a rule, is well defined, in the input signal, over a number L of those time windows in the input signal which in each case completely cover the charge distribution of the radiation event. This value represents the total charge of the quantum of radiation. The second value obtained from the N results of a numeric deconvolution of the charge distribution function of the stage noise, convoluted with the preamplifier transfer function which, as a rule, is well defined, in the input signal, over a number N of those time windows in the input signal which do not contain any charge attributable to any radiation event. This value specifies the instantaneous charge contribution of the stage noise to the measured charge. …<IMAGE>…

Abstract: An optical beam amplification and delivery system comprises a central station (2) having a phase conjugate mirror (26) and an optical amplifier (24) coupled together for amplification and phase conjugation of an input optical signal. Further provided is a local station (4), means (8, 10, 12, 14) for supplying a source optical signal at said local station (4) and optical fiber means (18) connecting said central (2) and local (4) stations. Coupling means (16, 19, 20) at said local station (4) couple said source optical signal into said optical fiber means (18) for amplification and phase conjugation at said central station (2) and for returning along said optical fiber means (18) to said local station (4). Said coupling means (16, 19, 20) decouple the returned optical signal from said optical fiber means (18) for use at the local station (4), said phase conjugate mirror (26) rendering said returned optical signal more nearly diffraction limited than an originally diffraction limited optical signal of the same power that is transmitted in a single path through said optical fiber means (18). Said optical fiber means (18) have a cross-sectional area sufficient to substantially inhibit stimulated Brillouin scattering by said return optical signal (Fig. 2). Further disclosed is a respective method of providing an amplified relatively diffraction limited optical signal for use at a first local station.

Abstract: A method is disclosed for processing an optical fiber (10) to include an integral lens (24) and a metallized outer coating (18). The fiber is first etched to include a tapered transition region and a thinned end region. The etched fiber is subsequently metallized and covered with a protective coating (20). A wet chemical etching technique is used to form an integral lens over the endface of the fiber. The protective coating is then stripped and any free metal is removed. The method allows for the fiber metallization to be in relative close proximity to the lens such that the fiber may be soldered into place near its endface, limiting any subsequent movement of the fiber relative to the aligned optical device.

Abstract: A semiconductor photodetector device includes a reversed conductivity type region (45) extending through a window layer (44) to a light absorbing layer (43), and a short carrier lifetime region (60) formed to surround the reversed conductivity type region such that the lifetime of minority carriers generated in a portion of the light absorbing layer outside a depletion layer (51), which is formed around the reversed conductivity type region, is significantly shorter than the lifetime of minority carriers within the light absorbing layer near the bottom of the depletion region. The photodetector device can respond quickly to variations in incident light to generate photocurrent, due to the reduction of response speed reduction which would be caused by carriers generated in the portion of the light absorbing layer outside the depletion layer.

Abstract: L'invention concerne les circuits intégrés et leur fabrication. Il est décrit un procédé pour réaliser des électrodes juxtaposées très rapprochées, telles que celles qu'on rencontre dans les registres à décalage à transfert de charge. Selon l'invention, on dépose une première couche de silicium polycristallin (14) et on fait une oxydation localisée sur une faible largeur, pour diviser la couche en deux électrodes (15 et 17). Puis on désoxyde totalement la zone de couche qui a été oxydée entre les deux électrodes, pour réaliser un espace évidé dans lequel on pourra loger une troisième électrode (38). Cette troisième électrode, en silicium polycristallin également, est déposée après qu'on ait reformé une légrère couche isolante sur les flancs des électrodes (15 et 17). Comme la largeur de l'espace évidé entre les deux premières électrodes est faible, il se forme une surépaisseur de silicium polycristallin. Il ne reste qu'à graver le silicium sur l'épaisseur de la couche déposée pour que ne subsistent des électrodes que dans les zones qui présentaient une surépaisseur. On a ainsi formé une troisième électrode très proche des deux premières, et pourtant sans recouvrement autre que sur les flancs des deux premières.

Abstract: The invention concerns a blast nozzle for high-pressure cleaning equipment, the nozzle having a high-pressure line and, connected to the line, a nozzle tip. In order to design the nozzle so that the high-pressure jet produced can be oriented in different directions, the invention proposes that the high-pressure line is in the form of a flexible high-pressure hose and carries a number of jointed elements loosely fitted concentrically over the hose. One end of each jointed element has an inner part-spherical surface while the other end has an outer part-spherical surface. Each inner surface lies flat against, and in frictional contact with, the outer surface of the next element and surrounds it to an extent sufficient for the two elements to be fixed with respect to each other in the longitudinal direction, but capable of being flexed with respect to each other when the force holding them in place is exceeded.
