Title: Method and device for focusing laser beam
Inventor: FUSE KEIJI
IPC: B23K26/064
Filed: 1996-03-12
Abstract: A laser beam condensing device which can be manufactured at low cost by using reflecting mirrors which can be machined at low cost, and which is capable of condensing a laser beam to a high energy density while eliminating any optical path difference, even if the optical axis of the incident beam is strayed. This device includes a first and a second reflecting mirror. An incident laser beam is deflected by these mirrors in the same direction. One of the two mirrors is a toroidal mirror, while the other is a spherical, cylindrical or toroidal reflecting mirror. The mirror surfaces of the two reflecting mirrors are machined so that the second reflecting mirror can cancel out any wave front aberration of the laser beam reflected by the first reflecting mirror.

Abstract: A protection switching system (10) includes a plurality of telecommunications modules (12, 14A. 14B, 16A, 16B) for processing and/or switching telecommunications signals. A first module (12) provides signals to one pair of modules (12A, 12B), which are in turn connected to another pair of modules (16A, 16B). A standby module (14B, 16B) controls the switching of all the modules (12, 14A, 14B, 16A, 16B) in the system (10) which require switching in the event that a standby module (14B, 16B) is activated. A controller monitor circuit (20) monitors the faults present on the working modules (14A, 16A) and, if a fault is detected, signals the corresponding standby module (14B, 16B), which in turn provides protection switching.

Title: Dispositif de fermeture automatique de couvercle de w.-c.
Inventor: GENESSE BRYAN V
IPC: A47K13/10
Filed: 1996-11-05
Abstract: La présente invention concerne un dispositif de fermeture automatique d'un couvercle de WC comprenant un bras (30) à tranche biseautée chargé par ressort et fixé pivotant à un support (52) de montage réglable, lui-même fixé sur le côté du réservoir (50) d'un WC. Le bras (30) bascule vers l'extérieur lorsqu'il est animé par le mouvement de rotation que l'on imprime à la poignée (38) de la chasse d'eau du fait que la tranche biseautée transforme ledit mouvement de sens vertical en un sens horizontal. Ledit mouvement horizontal fait pivoter le bras et le place en contact avec le couvercle (86) de manière suffisante pour provoquer la chute du couvercle de sa position ouverte habituelle vers une position fermée. Des amortisseurs (90) élastiques amortissent la chute du couvercle dont ils réduisent le bruit. Un second mode de réalisation utilise un solénoïde électromagnétique (98) fournissant le mouvement nécessaire à la fermeture du couvercle (86). Un troisième mode de réalisation emploie une barre de levier (106) encastrée sous un bras pivotant (104) pour modifier la direction vers le bas du mouvement de fermeture du couvercle en une direction vers l'extérieur.
