Title: Optical device packaging
Inventor: KASHYAP RAMAN
IPC: G02B6/34
Filed: 1994-01-31
Granted: 1999-11-23
Abstract: The invention provides a method of assembling a package comprising a photosensitive optical device (1, 2), the package having a window (5) positioned to allow optical frequency electromagnetic radiation from a source (18) to impinge on a photosensitive part (2) of the optical device. In one embodiment the invention enables a packaged intermediate product (6) to be fabricated, which may subsequently be formed into an external cavity semiconductor laser having certain specified characteristics, by writing a grating (15) into a photosensitive fibre (2). Use of a window (5) allows the characteristics of the laser to be defined after packaging so that, firstly a large stock of external cavity lasers having all possible characteristics need not be held, and secondly so that the reflectivity of the grating (15) need be chosen only once the degree of coupling between the fibre (2) and the laser diode (1) has been established, thus enhancing the performance of the external cavity laser.

IPC: H01R13/436
Filed: 1995-09-07
Granted: 2005-11-15
Abstract: An electrical connector assembly securely locks electrical contacts within a connector housing. The connector assembly includes a plurality of electrical contacts each having first and second longitudinally spaced locking elements. A connector housing includes an interconnection end and a contact insertion end. The connector housing-also includes an initial contact support member positioned adjacent the insertion end of the housing.

Abstract: La présente invention porte sur un appareil utilisant les techniques de nettoyage à sec pour nettoyer une tête de lecture/écriture (14) du type à transduction par contact comme celles des systèmes d'entraînement de bande de sauvegarde de données informatiques. L'appareil comprend un boîtier (30) renfermant une bobine débitrice (40) de bande de nettoyage, une bobine réceptrice (42) pour la bande utilisée ou souillée , et un train d'engrenage pour transmettre à la bobine réceptrice, à une vitesse de rotation réduite, l'énergie rotative provenant d'une source d'énergie externe, tel le cabestan d'entraînement de la bande. Le train d'engrenage comprend une pluralité d'engrenages qui constituent un système réducteur tel que la bande de nettoyage peut passer sur la tête à une vitesse de nettoyage efficace qui est substantiellement inférieure à la vitesse normale de lecture/écriture du dérouleur de bande. L'appareil comprend en outre un mécanisme d'obturation mobile (122) pour bloquer l'un de deux tracés lumineux entre un émetteur de lumière (94, 96) et un capteur de lumière faisant partie du système d'entraînement de la bande, ce qui permet de fournir un signal unique au dérouleur de bande. Le mécanisme obturateur est activé au moment de l'introduction dans le dérouleur de bande par la mise en tension de la bande de nettoyage contre le mécanisme obturateur de manière à le mettre en position opérationnelle de blocage du tracé lumineux sous l'effet d'un ressort, ce qui indique au dérouleur de bande qu'un appareil de nettoyage a été introduit dans le dérouleur de bande, de sorte que le cycle de nettoyage fonctionne pour une période de temps d'entraînement de la bande établie par le fabricant.

Abstract: A display element includes a disk which rotates through 160°-180° to display a bright or a dark side in a viewing direction in ON and OFF positions respectively.          An constantly on LED is arranged to illuminate the disk in ON position for viewing in an first arc including the viewing direction.  The disk masks the LED to viewers in the OFF position of the disk.  In addition to light from the illuminated disks, the components may be arranged so that viewers over a second arc may view the LED directly when  the   disk  is in ON position.  The elements may be arranged in arrays to form a changeable sign. Thus the array may be made up of single elements, of columns of such elements or of a combination of elements and columns.

Abstract: Ingress noise in a hybrid fiber-coax transmission system (10) may be reduced by employing asymmetric taps (30 1'-30 8',) between a pair of line extenders (28-28) for attenuating downstream and upstream information by different weights. The downstream weights of the taps are selected to achieve a substantial constant power level at each tap for individual subscribers (14-14). The upstream attenuation of each tap is selected to allow for a nearly constant level of subscriber-generated information to be received at the line extender while the subscriber generated upstream information is supplied to the taps at a constant value that is maximized to reduce the effect of ingress noise.
