Abstract: Le domaine extracellulaire du récepteur de l'érythropoïétine (protéine de fixation de l'EBO dite EBP) a été exprimé et surproduit dans E.coli. En régulant la concentration en oxygène et le pH pendant la fermentation on ne permet que la production de certaines variantes de protéines à terminaison amino native. Les procédés exposés permettent une bonne récupération de l'EBP purifié qui se fixe quantitativement à l'EPO. La protéine active purifiée concurrence le récepteur de l'EPO associé à la membrane pour se fixer à l'[<125>I] EPO et neutralise la stimulation dépendante de l'EPO dans un test de prolifération cellulaire. De plus la constante de fixation de l'équilibre des radioligands de cette interaction a été déterminée par immobilisation d'EPB sur gel d'agarose par l'intermédiaire d'une cystéine libre. L'EBP de l'invention a de nombreuses utilisations en matière de détermination de la structure des protéines par RMN ou cristallographie, de conception et de découverte de médicaments, et de thérapie. Une protéine de fusion de l'EBP et une chaîne lourde d'hémoglobine ont également été obtenues; ladite protéine, dite EBP-Ig, est une matrice préformée de dimérisation, également utile en matière de conception et de découverte de médicaments.

Abstract: A conventional facsimile machine re-dials by using another telephone line after an elapse of a predetermined period of time since when a communication error after a line connection has occurred, so that it takes a predetermined period of time to re-dial by using the other telephone line, and hence a receiving end may receive data transmitted from another facsimile machine during this period.  In order to prevent that, a facsimile machine of the present invention comprises: a plurality of line connecting means, each of which has a telephone line for transmitting/receiving data; a line selecting section for selecting a telephone line to be used when a plurality of telephone lines are connected; and an auto-dial sending section for changing over the telephone line currently selected by the line selecting section to another telephone line so as to make a call immediately, when the receiving end is busy.

Abstract: A method for manufacturing a bead inductor includes steps of forming a molded body of a resin or a rubber including a powdered magnetic substance, with a conductor coil formed by winding a metallic wire coated for insulation embedded therein; cutting both end portions of the molded body so as to expose end portions of the conductor coil; and attaching external terminals to exposed end portions of the conductor coil so as to be electrically connected. In order to increase reliability of connection between the conductor coil and external terminals, both end portions of the conductor coil prior to the forming step are immersed into a solder bath so as to include the cutting regions of both end portions of the molded body therein such that soldered portions are formed by removing insulation coating on both end portions of the conductor coil. A bead inductor is produced by using this conductor coil.

IPC: G02F1/35
Filed: 1999-07-30
Granted: 2009-04-14
Abstract: A fast, environmentally-stable fiber switch uses a Sagnac interferometer having an active fiber portion located asymmetrically in the loop of the interferometer. A pump pulse is applied to the interferometric loop and acts upon the active fiber portion to cause a change in its refractive index either by a thermal effect or by a non-thermal nonlinear effect. Because the active fiber portion is located asymmetrically in the loop, the change in refractive index of the active fiber portion is seen by the clockwise propagating light signal and the counterclockwise propagating light signal at different times, thus causing a temporary difference in the phase changes experienced by the two counterpropagating light signals. The temporary difference in the phase changes causes the two light signals to combine constructively at a switched output port of the input/output coupler of the interferometric loop until the phase changes of the two signals are again the same, at which time the signals combine at an unswitched output port of the coupler. The on-time of the switch is set primarily by the length of the Sagnac loop, and the fall time, which is caused by the Sagnac architecture, can be fast, even with a relatively slow active fiber.

Title: Block adaptive quantisation
Inventor: LANCASHIRE DAVID
IPC: G01S13/90
Filed: 1999-10-15
Granted: 2007-05-29
Abstract: A block adaptive quantisation device processes blocks of sample pairs to determine an aggregate or average value at 18. The average or aggregate value is applied to each of a number of exponent look-up tables 22 to 26, which output and exponent value (E) dependent on the extent of compression required. The exponent value is split by an exponent splitter into a remainder value (R) and a shift value (S). The remainder value is used to select one of a number of divide look-up tables to which the unsigned data sample is applied, and the shift value is used to apply a variable bit shift to the data sample (either before or after the division operation). Each divide look-up table 42 to 48 comprises the same group of divide look-up tables. The combination of the four look-up tables in the group, together with the variable bit shift defines a series of code tables made up of a group of divide look-up tables repeated at six dB intervals. The remainder value selects one of the code tables within the group, and the bit shift operation determines the selected one of the repeated groups. The code tables within the group are spaced logarithmically, as are the groups themselves. This arrangement considerably reduces the number of look-up tables required for a given processor, reducing memory requirement and increasing speed.
