IPC: G02B6/255
Filed: 2001-12-04
Abstract: A fusion splicing apparatus for fusion splicing end portions of optical fibers by butt discharging. Parameter data of a brightness distribution waveform of optical fiber in cross section is measured from a picked up image. A  degree of attribution for the measured parameter data is obtained from fuzzy operation data registered in advance, and the type of the optical fiber is identified through a fuzzy operation. The identified type of the optical fiber is collated with fusion splicing conditions for each type of optical fibers registered in advance. The collation result is diplayed.

Title: Improvements in and relating to telecommunications networks
Inventor: HUNNEYBALL TIMOTHY JOHN
IPC: H04L45/50
Filed: 2002-04-25
Abstract: A telecommunications network comprising an SDH ring (9) of a plurality of interconnected MPLS (Multi Protocol Label Switching) enabled network devices (2) (SONET / SDH / WDM multiplexers) is configured to support both central and distributed network / routing protocols. Central management of the network is effected by a central management terminal (1) by means of OSI protocols run over a first data communications network (DCN) (5) of embedded Data Communications Channels (DCCS) (5), (5a). Distributed management of the network is performed by means of MPLS / IP protocols run over a second data communications network (DCN) (6) of embedded Data Communication Channels (DCCS) (6), (6a), (6b), (6c), (6d). The topologies of the two DCNs (5), (6) are different. The central management DCN (5) extends (link 5a) to the central management terminal (1) via an Ethernet interface, whereas the distributively managed DCN (6) is blocked at the interface. Data devices (3), in the form of MPLS enabled switches or routers, are connected to the SDH ring (9). The distributed control DCN (6) extends (links 6a, 6b, 6c, 6d) to the data devices (3a), (3b), (3c), (3d), whereas the centrally controlled DCN (5) is prevented from extending to the devices (3). Thus an existing legacy optical network may be converted so as to run two DCNs in parallel, the first DCN (5) supporting OSI protocols (in a centrally managed environment) and the second DCN (6) supporting GMPLS (Generalised MPLS) protocols that strictly follow data traffic.

Title: Polymere et son utilisation dans la production de papier et de carton
Inventor: TAMMI ANNA-LIISA
IPC: D21H17/29
Filed: 2002-05-20
Abstract: L'invention concerne un copolymère stabilisé avec un polysaccharide cationique, qui est utilisé comme additif destiné à la production de papier ou de carton et pouvant améliorer la résistance d'une bande humide. Dans ledit copolymère, un acrylamide ou métacrylamide, un acide carboxylique vinylique et éventuellement d'autres monomères vinyliques sont utilisés comme monomères. La résistance à l'état humide d'une bande correspond à la résistance d'une bande de papier ou de carton pendant la production pour une teneur en matière sèche de 20 à 60 %. L'additif de l'invention améliore non seulement la résistance de la bande humide, mais également la résistance superficielle du produit. Par comparaison avec les additifs de la technique antérieure, un rapport relatif faible entre le nombre de chaînes latérales et les groupes cationiques est utilisé, puisqu'un polysaccharide ayant un caractère cationique supérieur offre une meilleure stabilité.

Patent CA-2448610-A1 (CA)
Inventor: LEIMER MARK ALAN
IPC: F01L3/08
Filed: 2003-11-07
Abstract: A valve stem seal assembly includes a retainer with one or more built-in sprees, a cavity at one end, an annular flange on the opposite end, and a cylindrical interior passageway therebetween. The built-in sprees extend from the bottom surface of the cavity to the annular flange. The valve stem seal assembly also includes a jacket made of an elastomeric material integrally bonded to the retainer. When the valve stem seal assembly is fitted atop the valve guide, a gap is formed between the bottom surface of the cavity of the retainer and the top surface of the valve guide to accommodate manufacturing tolerances in the height of the valve guide. The jacket is integrally bonded to the retainer by introducing material into the cavity, through the built-in sprues, and out of the bottom of the annular flange. One preferred method of manufacturing the valve stem seal assembly provides placing the retainer atop a tool plate that contains a circumferential groove, positioning the retainer to properly receive an elastomeric material, pouring the elastomeric material through the built-in sprees forming the jacket and curing the elastomeric material until the jacket is bonded with the retainer. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Filed: 2003-01-21
Abstract: The invention relates to a method and a device for measuring optical distanc e by emitting an amplitude-modulated, bundled optical signal and by receiving the signal reflected on the target object. The modulation frequency is continuously regulated by means of a regulation loop in such a way that a fixed phase difference, which is independent from the distance, is maintaine d between the emitted signal and the received signal. The aim of the invention is to reduce the means required for the distance evaluation circuit, simultaneously maintaining a high level of precision, and to increase the obtainable regulation speed. To this end, the phase difference is detected b y means of a phase comparator.

Title: Radio communication method and system for communication between a plurality of radio communication terminals
Inventor: OGAWA HIROYO
IPC: H04W84/12
Filed: 2003-01-09
Abstract: A reference local oscillation signal transmitting station (1) radiates a reference local oscillation signal to a service zone. The signal received by each radio slave station terminal (2) is partially branched and inputted to an injection-locked oscillator (6), thereby obtaining a local oscillation signa l synchronized with the reference local oscillation signal. The slave station terminal (2) branches the thus obtained local oscillation signal into two, o ne of which is inputted to a transmission frequency converter (mixer) (7), and the other of which is inputted to a reception frequency converter (mixer) (8 ). An IF band transmission modulation signal is inputted to the mixer (7), frequency-converted to a radio frequency band, and thereafter transmitted. O n the other hand, a received radio modulation signal is inputted to the mixer (8), down-converted, and thereafter inputted to an IF band demodulator (10), thereby restoring information signal. The invention can resolve the problems of phase noise occurring due to a millimeter wave band oscillator and of signal quality degradation due to a frequency offset, and can raise the frequency utilization efficiency at the same time.
