IPC: G02B6/38
Filed: 2000-07-17
Abstract: The plug part (1) has at its disposal a protective flap (14) which on a bearing section is linkedly mounted on the plug housing (2) in a manner such that on inserting the plug part into a socket part it is movable from a closure position with a covered end-face side of the plug pin into an opening position with an open end-face side of the plug pin.

IPC: B41J2/16
Filed: 2000-10-18
Abstract: A nozzle plate of an ink jet printing head is formed so that its surface facing toward the ink drop discharge direction will have protruding parts around each of its nozzle holes. Each protruding part is formed in the shape of a circle that is concentric with a corresponding nozzle hole, and the outer edge of the protruding part is formed so as to have an appropriate slope. Due to the configuration of the nozzle plate, a wiper blade can make good contact with the surface (protruding parts) of the nozzle plate around the nozzle holes and ink around the nozzle holes can be cleaned successfully in wiping operation, thereby the ink drop discharge properties of the ink jet printing head can be stabilized and improved. Such a configuration of the nozzle plate is realized by electrodeposition without using a photoresist. Therefore, the shape of the nozzle hole is not affected by the coating status of the photoresist, the precision of a patterning image which is used for the exposure and development, the precision and life of a mask, etc. Therefore, the dimensional accuracy (diameter, roundness, etc.) of the nozzle holes can be improved, manufacturing yield of the ink jet printing heads can be increased, manufacturing costs can be reduced, and high quality printing can be realized.

Title: Method for custom corneal corrections
Inventor: ALEXANDER J RANDY
IPC: A61F9/01
Filed: 2000-10-19
Abstract: A method for customizing corneal corrections includes superposing an imaginary reference field (grid) on the anterior surface of the cornea of an eye to divide the corneal surface into reference areas. Also, a diagnostically determined refractive power map for the cornea is created. An incising laser beam is then directed through an individual reference area to a focal spot. Next, movement of the focal spot along the laser beam path is selectively accomplished to photoalter a predetermined volume of stromal tissue. Subsequently, based on the refractive power map, the predetermined volume of stromal tissue that is to be photoaltered is identified for each specific reference area. Accordingly, the steps of directing the beam and moving the focal spot are then repeated using selected reference areas until the required corneal correction is achieved.

Title: Detection d'erreurs dans un systeme de communication
Inventor: STELZL RUDOLF
IPC: H04L49/111
Filed: 1999-08-02
Abstract: L'invention concerne un procédé permettant de détecter des erreurs dans un système de communication, notamment un système de communication ATM (mode de transfert asynchrone). En l'absence de signaux de communication, des signaux de surveillance sont injectés au début d'au moins une ligne de surveillance (7,8) du système de communication puis prélevés à la fin de cette ligne (7, 8). Selon l'invention, la ligne de surveillance (7, 8) se trouve dans un dispositif de commutation (1) du système de communication. L'absence de tout signal à la fin de la ligne de surveillance (7, 8) permet de déduire la présence d'une erreur dans le dispositif de commutation (1). En outre, un dispositif de commutation (1) présente une ligne de surveillance (7, 8) qui est dotée, au début, d'une unité d'alimentation (2) et, à la fin, d'une unité de prélèvement (3). L'unité de prélèvement est conçue de telle façon qu'elle détecte et prélève les signaux de surveillance injectés par l'unité d'alimentation (2). L'invention permet notamment de déclencher un signal d'indication d'alarme (AIS) très rapidement après la détection d'une erreur dans le dispositif de commutation (1).

Title: Simultaneious single mode and multi-mode propagation of signals in a double clad optical fibre
Inventor: CHEN YIHONG
IPC: H01S3/094
Filed: 2001-04-12
Abstract: An optical amplifier having a suitable length of Er/Yb co-doped double clad optical fibre is used to amplify an input optical signal. The inner clad of the double clad optical fibre supports the propagation of a multi mode signal used to excite Er/Yb co-dopants in the double clad optical fibre. Simultaneously, a single mode signal launched from a single mode laser pump co--propagates with the input optical signal in the core of the optical fibre. In this model, single mode light travels in the single mode core region and the multi mode pump light is mainly in the clad region. The interaction between the two laser pumps is negligible.
