Title: Data demodulator
Inventor: SATO TOSHIFUMI
IPC: H04L27/233
Filed: 1993-02-25
Granted: 1997-09-30
Abstract: A data demodulator demodulates a differential phase-shift-keying (DPSK) modulated receive signal to produce symbol rate demodulated data.  A phase detection means, delay means, and phase difference detection means connected in cascade detect the phase of the receive signal and generate a phase difference signal having N-phases, in synchronism with respective clock signals. A decision means generates decision data on the basis of a phase range of the phase difference signal, and a decision error computing means computes a decision error on the basis of each phase of the phase difference signal and a corresponding decision phase of the decision data.          Decision error adding means, and respective decision error registers accumulate and store respective decision error sums.  A signal processing means reads out the decision error sum from each of the decision error registers, computes a sampling phase signal by a prescribed computing technique, and outputs a sampling phase signal.  Finally, a sampling means generates the symbol rate demodulated data by sampling a phase of the decision data and the sampling phase signal.

Abstract: Capteur (10) pour détecter l'entraînement d'un fluide de faible densité dans un fluide de densité plus élevée, en particulier l'entraînement d'un gaz frigorigène dans un liquide frigorigène. Typiquement, le capteur (10) est installé dans une canalisation d'approvisionnement en liquide à pression plus élevée (24) d'un système de réfrigération (26). Le capteur (10) a un flotteur différentiel (16) comportant un élément flotteur (54) monté sur pivot (56) dans une chambre (14) raccordée à la canalisation d'approvisionnement (24). L'élément flotteur (54) a une densité plus élevée que celle des deux fluides dans lesquels il fonctionne, mais l'emplacement du pivot (56) en un point intermédiaire de la longueur de l'élément flotteur (54) donne une densité nette pour le flotteur différentiel (16) qui est inférieure à celle de l'un des fluides. Le flotteur différentiel (16) peut donc supporter un fonctionnement à haute pression, disons 2 MPa, et peut agir comme flotteur pour détecter la présence ou l'absence du fluide de plus faible densité dans le fluide de densité élevée. Le flotteur différentiel (16) peut aussi être utililsé comme dispositif de maintien du régleur (20) ou en remplacement des tubes capillaires servant à régler le débit du frigorigène.

Abstract: Redundant facility payload signals (12, 14) received by redundant interface modules (16, 18) are redundantly provided (28, 30; 32, 34) to redundant downstream modules (24, 26) in an equipment (10). A non-symmetrical facility protection algorithm is resident in the B interface module (18). Symmetrical equipment protection algorithms are independently resident and operative in each module of pairs of identical A and B modules at each stage of the data stream. Module or data failures result in switchover only of the disabled data path or module so that the ability to transport payload is maintained and other modules or data paths are unaffected. Facility switchover is effected by detecting a working line failure and transmitting commands to switch the protection line to the A path modules. Equipment switchover is effected by checking for a working or protection module failure independently in each path and independently communicating independent switchover decisions to the other side and downstream. The methodology and mechanism are disclosed in a SONET element embodiment, although the invention is applicable in other contexts.

Abstract: In a line accommodation circuit for use in combination with a cell exchange apparatus to carry out a conversion operation of a sequence of input data signals into a sequence of asynchronous transfer mode cells sent to the cell exchange apparatus, first and second function systems which are identical in structure with each other are supplied with the input data signals in parallel and are switched from an active system to a standby system by a switching operation indicated by a system controller.      During the switching operation, the active system stops the conversion operation and produces the asynchronous transfer mode cells left therein while the standby system starts the conversion operation to produce a following asynchronous transfer mode cell. A test cell is inserted in the active system after a last one of the asynchronous transfer mode cell held in the active system and placed in the standby system before a following asynchronous transfer mode cell following the last asynchronous transfer mode cell. The test cell is at first detected by the standby system and thereafter detected by the active system. When the test cell is detected by both the active and the standby systems, the next asynchronous transfer mode cells succeeding the following asynchronous transfer mode cell are sent from the standby system which is rendered into a new active system. The active system which interrupts the conversion operation is rendered into a new standby system.

Title: Extrusion die with interchangeable extrusion nozzles
Inventor: LUPKE MANFRED A A
IPC: B29C48/11
Filed: 1992-05-11
Granted: 2000-02-08
Abstract: The annular channel elongate nozzle of an extrusion die (10) suitable for use for extrusion into a travelling mold tunnel, has an inner core (16) profiled for attachment to any one of a number of interchangeable end fitting nozzles outlet (100). The profiling takes the form of a step between an upstream portion (22) of the core and a reduced diameter downstream portion (24). Each end fitting outlet has an annular sleeve (34) to fit about the downstream core portion to extend the surface of the upstream portion of the core. The sleeve abuts the step (26) thereby locating the end fitting outlet correctly. No locking means is necessary between the end fitting and the core in the region of the nozzle. Attachment may be effected between them at a location downstream of the point at which extrudate is extruded into the mold tunnel.  Hence, attachment is not hampered by the presence of extrudate and the attachment (40, 20, 25) may not interfere with the flow of extrudate.

Title: Low polarization sensitivity gold mirrors on silica
Inventor: FILAS ROBERT WILLIAM
IPC: G02B1/10
Filed: 1995-07-06
Granted: 2000-01-11
Abstract: Gold is useful for infrared polarization-insensitive mirrors on silica. However, gold does not adhere to bare silica. The adherence is enhanced by depositing an optically thin glue layer of Ni-P on a silica surface after sensitization of the surface with SnF2 and activation with PdCl2/HCl. The Ni-P layer is deposited in a thickness sufficient to enhance adherence of gold to the surface of silica but insufficient to act as a barrier to the passage of infrared radiation to or from the gold layer. One measure of the Ni-P thickness is the absorbance of the glue layer of >0.008 at 550 nm (>0.003 at 850 nm) as measured by a spectrophotometer. A 100- 150 nm thick gold layer, deposited by e-beam deposition on this adhesion layer, adheres well enough to pass the commonly used "Scotch tape adhesion test". The ability to make gold adhere to silica with very low optical loss is useful in fabrication of lightwave devices which require the use of reflecting surfaces, such as on optical fibers or waveguides.
