Patent CA-2428379-A1 (CA)
Inventor: PASSARELLI FRANK JR
IPC: G01N29/34
Filed: 2001-11-14
Abstract: The disclosed invention mounts transmitting and receiving electrical coils (52, 54) within channels or chambers (48, 50) formed by the notched ends of magnets (24, 28) closest to the metallic structure under test (40) where said magnets (24, 28) are arranged to form annlar arrays (20, 22) of an electromagnetic acoustic transducer (EMAT) pair applicable in non-destructive testing. The detection of one or more electromagnetically-induced resonant frequencies at shifted locations indicates te presence of one or more flaws (58, 60) in the metallic structure under test (40). The novel recessed mounting of the coils provided by the channels or chambers (48, 50) substantially reduces the observed electrical cross-talk between coils (52, 54) over the prior art and reduces the likelihood of the coils (52, 54) making contact with the subject metallic structure under test (40) as it is in longitudinal motion relative to the coils (52, 54).

Title: Silicon production process
Inventor: WAKAMATSU SATORU
IPC: C01B33/03
Filed: 2002-10-18
Abstract: A silicon production process which improves the production efficiency of trichlorosilane while an industrially advantageous output is ensured and the amount of the by-produced tetrachlorosilane is suppressed. This process does not require a bulky reduction apparatus for the by-produced tetrachlorosilane,can construct a closed system, which is a self-supporting silicon production process, can easily control the amount of the by-produced tetrachlorosilane and therefore can adjust the amount of tetrachlorosilane to be supplied to a tetrachlorosilane treating system when the tetrachlorosilane treating system is used.   This process comprises a silicon deposition step for forming silicon by reacting trichlorosilane with hydrogen at a temperature of 1,300°C or higher, a trichlorosilane forming step for forming trichlorosilane by contacting the exhausted gas in the above silicon deposition step to raw material silicon to react hydrogen chloride contained in the exhausted gas with silicon, and a trichlorosilane first recycling step for separating trichlorosilane from the exhausted gas in the trichlorosilane forming step and recycling it to the silicon deposition step.

Abstract: The equations of friction and wire-friction and innovative hinges are exploited to substantially decrease the tensile forces of all wires of a life-saving door-detachment device, which automatically or manually detaches the jammed and/or locked doors from the body of a transport system, when it has come to rest after being involved in an accident and/or fire, by pulling the hinge-pins out of the hinge-holes and/or fracturing the hinge-members. Catch bands thereof prevent the detached doors from flying off and striking rescue-workers and others in the vicinity. As a result, passengers can escape from the vehicle within seconds or be quickly rescued. The shorter the evacuation time, the greater the survival chance, particularly, when the passengers are severely injured and/or the transport system catches fire. A catch pin serves as a catch band and member of a doorstop to keep the door open in one of the defined positions.

Abstract: La présente invention concerne des logiques de calage temporel des émissions en provenance de plusieurs stations de base à destination d'un terminal. Pour réaliser le calage temporel, on détermine les différences entre les heures d'arrivée des émissions des stations de base, telles qu'on les constate au niveau du terminal, et on les fournit au système qui les utilise pour reprendre la synchronisation des stations de base de façon que les trames radio spécifiques du terminal arrivent à ce terminal dans un créneau de temps particulier. Selon l'une de ces logiques, on découpe la différence de temps entre deux stations de base en une différence de temps du niveau trame et une différence de temps du niveau de la bribe. Dès qu'on lui demande d'effectuer des mesures de différence de temps et d'en rendre compte, le terminal mesure la synchronisation au niveau de la bribe pour chaque station de base candidate, par rapport à une station de base de référence. En outre, le terminal mesure également la synchronisation au niveau de la trame et ne reporte cette information dans la mesure de différence de temps que si c'est nécessaire. Dans les autres cas, le terminal applique pour la partie du niveau trame une valeur définie telle que zéro.
