Patent CA-2272270-C (CA)
Inventor: OHLSEN IB
IPC: F23C1/02
Filed: 1998-01-13
Granted: 2007-10-02
Abstract: A method as well as a burner are provided for introducing solid, liquid or gaseous fuel into the burning zone of a kiln, such as a rotary kiln for manufacturing cement clinker or similar products, where fuel is conducted through substantially concentric ducts (1, 6) and where primary air is conducted through two likewise concentric and annular ducts (8, 9) arranged around the fuel ducts, where the air in one of these air ducts (9) is made up of axially flowing air, whereas the air in the second air duct (8) comprises air which is caused to rotate about the centre axis of the burner, and where the portions of primary air can be -independently controlled. The peculiar feature of the burner is that the primary airstreams are mixed at a relatively low velocity in a collecting duct (15) into a primary airstream which is subsequently accelerated up to a desired, relatively high velocity prior to being injected into the kiln via an annular nozzle (14). There is thus obtained effective mixing of fuel and air in an operationally reliable manner with a minimum loss of pressure, and the flame shape can be adapted to the optimum desired.

Abstract: Breaking hard compact materials, such as rock and concrete, is based upon a controlled-fracturing process. A high-pressure foam is used to pressurize a predrilled hole of appropriate geometry. The high-pressure foam is delivered to the bottom of the drilled hole by a barrel inserted into the hole. The barrel includes a seal near the bottom of the hole. By restricting and controlling the pressure of the high-pressure foam to the bottom of the hole, a controlled fracturing is achieved which results in the fracturing and removing of a large volume of material at a low expenditure of energy. The foam-injection method produces almost no fly rock or airblast. The foam-injection method may be used to fracture, remove and/or excavate any hard material such as rock or concrete. The method may be used in either dry or water filled holes and the holes may be in any orientation. The foam injection apparatus is carried on a boom mounted on a carrier. An indexing mechanism allows both a drill and a foam injection apparatus to be used on the same boom for drilling and subsequent high-pressure foam injection.

Abstract: The intervals (120, 125) between the spectra (111, 112, 113) of carrier waves are greater than or around the coherent bandwidth, and hence the carrier waves can receive mutual correlative phasing.      Therefore, even if the spectrum (112) receives phasing by a specific carrier wave during call and consequently the line quality degrades, the call can be continued by the other spectra (111, 113). In this case, the other received signals are synchronously detected and combined by a maximum ratio composite method, and carriers can be regarded as independent of each other. Therefore, diversity reception by a maximum ratio composite method of branches, the number of which is equal to the number of carriers used for communication, is possible. Since the intervals between the frequencies are so set by using existing circuit techniques that the carriers are almost mutually in correlation, no radio circuit having frequency characteristics of wide band nor processor for high-degree digital signal processing is needed.

Granted: 2002-09-17
Abstract: An improved digital decision directed phase locked loop (DD-PLL) for use with short block codes using phase shifting keying (PSK) modulation. The improvement involves a conventional digital phase lock loop which is modified to base its loop corrections on the results obtained by decoding the short block code rather than on a symbol by symbol basis as is customary in conventional DD-PLLs. The improved method of loop corrections involves retaining the symbol data pending the decoder's decision, derotating the retained data in accordance with the decoded result, and integrating the derotated data to form a composite estimator upon which to base the loop correction. In its preferred embodiment, the invention uses an (8, 4) biorthogonal code with quatenary PSK.

Selon la méthode, on analyse les cellules extraites du liquide corporel d'un individu au moyen d'ARNm à la recherche d'au moins un gène spécifique du cancer; et/ou on analyse les cellules extraites d'un liquide corporel d'un individu au moyen d'ADN et/ou d'ARNm à la recherche d'au moins un gène spécifique du cancer, et on effectue la même recherche sur des cellules non cancéreuses du même individu en vue de comparaison. En particulier, on analyse les cellules et les cellules cancéreuses à la recherche d'au moins un gène associé au cancer, puis on effectue la même recherche sur des cellules non cancéreuses du même individu en vue de comparaison. Les gènes spécifiques du cancer sont notamment les oncogènes, les gènes suppresseurs de tumeur mutés et les gènes qui ne sont sensiblement pas exprimés dans les cellules non cancéreuses extraites du liquide corporel étudié. Les gènes associés au cancer sont par exemple spécifiques de tissus, corrélés avec la capacité de former des métastase que possèdent les cellules cancéreuses circulantes, codent pour des récepteurs d'hormones stéroïdes, sont des gènes de chimiorésistance et/ou sont corrélés à l'immunomodulation, à la prolifération cellulaire ou à l'apoptose. L'invention concerne avant tout l'utilisation de ladite méthode pour le diagnostic in vitro du cancer. Elle concerne également l'utilisation des cellules cancéreuses disséminées et micrométastasées, caractérisées selon l'invention, pour tester des substances afin d'étudier leur activité antinéoplasique, ainsi que des moyens permettant de mettre en oeuvre ladite méthode.

Title: Output device, method of controlling it, and storage medium
Inventor: FUKANO KAZUKO
IPC: G06F3/153
Filed: 2000-10-27
Granted: 2007-08-21
Abstract: An output device (103) can be quickly and easily set to the operating parameters required for a particular output process. The output device has RAM (204) that temporarily stores the control parameters, and flash ROM (206) that stores the same parameter values in a nonvolatile manner. Specific parameter values are stored in RAM (204) in response to a specific command from the host (102). A customization command causes the output device (103) to save the operating parameters from RAM (204) into the flash ROM (206). Another customization command causes the output device (103) to restore the parameters from flash ROM (206) to RAM (204). A particular operating environment defined by the parameters stored in nonvolatile memory can therefore be quickly reset en masse.

Abstract: Cette invention a trait à une technique et à un dispositif permettant de détecter des modifications scéniques entre les champs successifs d'un signal de télévision numérique. Des trames I, qui débutent les nouveaux groupes d'images (GOP), sont alignées avec des modifications scéniques. Lors de la phase de pré-traitement (205, 210), on calcule, pour chaque champ d'entrée successif, le changement dans la somme des différences de pixels entre des champs impairs successifs ou des champs pairs successifs. Une modification scénique est détectée lorsqu'une valeur positive importante de modification de somme est suivie d'une importante valeur négative. Il n'est pas décidé quel type d'image sera utilisé avant la phase finale de codage (225, 235). Il est possible d'invalider les trames I lorsque le niveau d'un tampon de codage est trop élevé. Un compteur remet à zéro l'indication de modification scénique pour éviter un état de modification scénique perpétuel pour des transitions photo mouvement. En mode film, le codage axé sur l'image recommandée MPEG est désactivé lorsqu'une modification scénique se produit à la limite d'un champ, par exemple, lorsqu'il n'existe pas de champ redondant dans l'image.
