Patent CA-2277805-C (CA)
Inventor: NAKAMURA NAOKI
IPC: C03C4/00
Filed: 1999-07-12
Granted: 2003-09-16
Abstract: A nonlinear optical silica material mainly consisting of SiO2-GeO2 to which hydrogen or halogen element X is added. Oxygen bonded to Ge contained in the nonlinear optical silica material is replaced by H or X, and one Ge has two Ge-O bonds and one Ge-H (or Ge-X) bond at Ge points where nonlinearity is exhibited in the silica material. The Ge-H (or Ge-X) bond does not relate to a crystal network, so that when the polarity is oriented in order to exhibit nonlinearity at Ge~, an electric field to be applied can be lowered, and when a optical semiconductor hybrid element or the like is produced, other portions of the semiconductor elements can be prevented from being broken or degraded in performance. An insulating film can be interposed between the semiconductor substrate and the nonlinear optical silica film to prevent undesired impurities from dispersing into the semiconductor substrate and other elements and preventing a defect from being caused in the crystal of the substrate due to the silica film.

Abstract: L'invention concerne un procédé de codage ou de décodage d'un signal audio qui combine les avantages du traitement appelé mise en forme temporelle du bruit (TNS = Temporal Noise Shaping) et de la substitution de bruit. Un signal audio temporel discret est d'abord transformé dans la plage de fréquence de façon qu'il soit possible d'obtenir des valeurs spectrales du signal audio temporel. Ensuite, est exécutée une prédiction des valeurs spectrales relatives à la fréquence, pour qu'il soit possible d'obtenir des valeurs résiduelles spectrales. Dans les valeurs résiduelles spectrales sont détectées des plages qui comprennent des valeurs résiduelles spectrales avec des caractéristiques de bruit. Les valeurs résiduelles spectrales se trouvant dans les plages de bruit subissent une substitution de bruit, après quoi des informations concernant les plages de bruit ainsi que la substitution de bruit sont introduites dans des informations latérales d'un signal audio codé.

Title: Finish topping machine for bulb crops
Inventor: SHUKNECHT LEE N
IPC: A23N15/08
Filed: 1998-04-20
Granted: 2004-07-06
Abstract: A finish topper for bulb crops having a plurality of longitudinal, parallel, generally horizontal, spaced-apart moving belts (64, 66, 68, 70, 72) for conveying bulbs through the apparatus. Adjacent belts are driven at different linear speeds. In a preferred embodiment, alternate belts are replaced by stationary rails (56) to maximize the speed differential. Below and adjustably close to the belts is a driven rotating blade (80) for cutting the bulb stems and also exerting a downwards draft of air through the belts. Onions introduced onto the belts are conveyed through the apparatus by the belts, and the differential in speed between the moving belts and stationary rails causes the bulbs to rotate and gyrate randomly as they are being conveyed. Because the belts are spaced apart, the bulbs assume momentarily an attitude to permit the uncut stems of bulbs to extend downwardly between the belts.

Title: System consisting of an oil pump and of a valve for oil burners
Inventor: LUESCHER MICHEL
IPC: F23N1/00
Filed: 2000-01-27
Granted: 2007-01-09
Abstract: The invention relates to a system made of an oil pump and of a magnet valve for preventing oil from dripping when the oil burner is switched off. The inventive system is provided with an oil pump (23) and a magnet valve (10) which has a closing body (16) that comprises an oil flow borehole (17). The closing body (16) is displaceably located in a borehole (12). An oil line (11) goes through the borehole (12). The oil flow borehole (17) of the closing body (16) complements the oil line (11) in a first position of the inventive magnet valve (10). The oil flow is thus released. The closing body (16) interrupts the oil line (11) in a second position of the magnet valve (10). A vacuum is simultaneously generated in said second position. The vacuum reverses the direction of oil flow in an end section (15) of the valve (11). The oil is thus prevented from dripping.

Abstract: The invention relates to flow control in data transmission in telecommunications systems, particularly in wireless telecommunications systems. In the present invention flow control information is tunnelled over a connection leg (Iu) which does not support flow control on a lower transmission protocol layer (ATM) underlying a user level (LAC). The nodes (RNC, 3G      MSC) at the both ends of the leg (Iu) are arranged to use the flow control information to control the data flow on the lower transmission protocol level (ATM) of the leg. In other words, the transmission of new data on the lower transmission protocol level (ATM) is ceased or the data rate decreased when the flow control information activates the flow control in the transmitting node, and similarly, the transmission of new data on the lower transmission protocol level (ATM) is restarted or the data rate increased when the conveyed flow control information deactivates the flow control. The need of flow control may be recognized from the receiving buffer status on the lower transmission protocol level or from incoming flow control information received over the following leg of the connection in the downlink direction.
