Abstract: L'invention se rapporte à un moyen de fabrication de coupleurs de fibres optiques monomode 1x8 à large bande. On a découvert qu'on peut faire fusionner un coupleur de fibres optiques 1x7 (12) en enroulant en torsades six fibres (1, 2, 3, 6, 7, 8) autour d'une septième fibre (10) centrale, en chauffant la région de contact entre les sept fibres et en les étirant jusqu'à obtenir la répartition désirée de puissance optique parmi les sept fibres. Des coupleurs à la fois de type 1x6 et 1x7 peuvent être produits de cette façon selon l'ampleur de l'étirage. En utilisant un tel coupleur combiné à un coupleur 1x2 classique et à un coupleur 1x2 à large bande, on peut fabriquer des coupleurs 1x8 en recourant uniquement à deux ou trois coupleurs séparés à la place des sept coupleurs qui sont nécessaires dans des structures de coupleurs en arbres. De plus, en profitant des comportements de réponse aux longueurs d'ondes sélectionnées qui sont caractéristiques de chaque coupleur dans l'ensemble combiné, la combinaison de coupleurs 1x2 et 1x7 ou 1x6 est réalisée de façon à assurer une uniformité de couplags relativement accrue sur une largeur de bande de +/- 50 nm autour des longueurs d'onde de fonctionnement du coupleur 1x8.

Abstract: An arrangement for controlling a zero crossing switch (32) in order to connect a source of zero crossing AC voltage (20) to and disconnecting it from an AC load line is disclosed herein along with its method of operation. To this end, means (22) are provided for producing externally controlled command signals (12) intended to control when the switch (32) connects and disconnects the load line to and from the AC voltage. At the same time, a specific window of time is selected, which window begins a particular period of time prior to and includes at least certain zero crossing points of the AC voltage. Internally controlled command signals (16) are produced in response to the AC voltage and externally controlled signals (12) for actually controlling when the switch (32) connects (ON) and disconnects (OFF) the load to and from the AC voltage. These internally controlled signals (16) are produced such that either an ON or OFF signal, but not both, is produced entirely throughout the specific window of time in order to prevent command signals from switching between ON and OFF states within any given window of time. This, in turn, reduces current surges at the output of the zero crossing switch (32), thereby reducing electromagnetic interference (EMI).

Abstract: Storage, manipulation, and retrieval of files, for example data representations of scanned documents, is facilitated by establishing a relationship between an arbitrary, image domain file label (160) and a computer recognizable text domain file name for the file. Selection of the arbitrary, image domain file label is interpreted as a selection of the related file. The arbitrary, image domain file name is assigned by way of a paper form (150) or the like, and may be assigned at the time of document storage. The arbitrary, image domain file label facilitates the meaningful naming of a file for storage when a keyboard or other typical text entry apparatus is unavailable, such as when inputting a document for storage by way of a facsimile machine. Character recognition is not performed on the arbitrary, image domain file label, so the burden on the processing resource is minimized, while errors from inaccuracy are eliminated. Selection of a file for processing by way of its arbitrary, image domain file label may be by appropriate indication on either a screen display (Fig. 13) or a printed form (Fig. 12).

Abstract: A semiconductor laser module is used for transmitting signals by optical fiber in optoelectronic communication. The module comprises a semiconductor laser (1), a lens (2), a receptacle (6) and a lens holder. Reflection beams at an end of a fiber (3) must not return to the semiconductor laser. To deviate the reflection beams from the semiconductor, a key-shaped glass block (10) is mounted in the receptacle. Conventionally the block has been in tight contact with the end of a fiber. Repetition of putting on and taking off ferrules contaminates the glass block. Adhesion of dust deteriorate the performance against noise induced in the laser by the return of the beam. To avoid the adhesion of dust to the surface of the transparent block, the key-shaped transparent block (10) is inserted into an axial hole of the receptacle, separating from the block. A gap between the block and fiber prohibits dust from cohering to the block. The deviation of axes of the receptacle and lens holder is small enough. The assembly is easy. The coupling between the receptacle and lens holder has strong mechanical strength.
