IPC: G01S15/89
Filed: 1989-10-19
Abstract: In order to measure a reflecting structure on a volume layer, at least one sound or ultrasound wave packet is emitted by a transducer matrix (1a), which wave packet arrives at the layer (4) coherently. The echo signals on each element (1) of the transducer matrix are processed separately, signals corresponding to the echos of each individual volume element (4a) onto all the transducers of the matrix (1a) being determined on the basis of defined transducer-element/ volume-element-distances (rnm) by means of a correlating calculation. The two-dimensional velocity field of the structure in the layer (4) is furthermore determined by means of two or more transmitted wave packets and evaluation of the resultant phase differences and frequency differences. <IMAGE>

Abstract: The present invention concerns a process for producing a grain-oriented electrical steel sheets by means of a rapid quench-solidification process, for example, a continuous casting by a twin roll strip caster. The feature of the present invention resides in quenching to solidify molten steels into a thin cast sheet of 0.7 to 3.0 mm thickness, at a cooling rate of greater than 50°C/sec. in the central portion along the direction of thickness of the thin cast sheet, cooling the sheet at a cooling rate of greater than 10°C/sec. in a temperature range between 1300 to 900°C and then applying cold rolling for once or twice or more including intermediate annealing under a final cold rolling reduction rate of not less than 80%. In the present invention, precipitate that function as an inhibitor can finely be dispersed by adding 0.02 to 0.2% of Nb into the molten steel ingredients thereby stably produce a grain-oriented electrical steel sheet of high magnetic flux density by means of a rapid quench-­solidification process. Further, since thin cast sheet of desired thickness within a range from 0.7 to 3.0 mm can be produced by the rapid quench-solidification process, thin cast sheet can be cold rolled to a final thickness of less than 150 µm by applying a cold rolling at a reduction rate optimum to magnetic properties, as well as an extremely thin grain-oriented electrical   steel sheet of less than 150 µm (0.15 mm) thickness can be produced in a simple production process and at a reduced cost, which has been remarkably difficult to produce and required expensive cost so far.

Abstract: Apparatus and method for determining the identity and concentration of one or more components in a test atmosphere having a known concentration of oxygen. A solid electrolyte oxygen sensor (100) is used, having a first solid electrolyte wall (113) in contact with, and interposed between, a first electrode (111) and a second electrode (112) and a second solid electrolyte wall (213) in contact with, and interposed between a third electrode (211) and a fourth electrode (212). The second and fourth electrodes (112, 212) are in communication with the test atmosphere. A partition wall (127) separates the first and third electrodes (111, 211) forming a first chamber (114) bounded by the first wall (113) and the partition wall (127) and a second chamber (214) bounded by the partition wall (127) and the second wall (213). Diffusion limiting means (118, 218) inhibit gas-flow of the gas from the test atmosphere (104) to the first chamber (114) and from the first chamber (114) to the second chamber (214). A first negative voltage (or positive voltage when then unknown component has a concentration larger than that of a stoichiometric gas mixture) is applied to the first and second electrodes generating a first electrical current on a first electric current plateau. Simultaneously the EMF across the third and fourth electrodes is measured. These two numbers are correlated with a table to determine gas component identity and concentration.

Abstract: L'invention se rapporte à un synthétiseur de fréquences indirect utilisable dans des systèmes radio à cellules, qui se caractérise par une plus grande finesse de résolution et par une réduction des fréquences parasites et/ou des brouillages de phase et qui permet d'inclure plus facilement un grand nombre de canaux dans une largeur de bande donnée. Ce synthétiseur comprend un détecteur de phase (110) réagissant à un signal de référence et à un signal de commande de phase, afin de produire un signal de commande qui varie en fonction de la différence de phase entre le signal de référence et le signal de commande de phase. Un oscillateur commandé en tension (118) réagissant au signal de commande produit un signal de sortie dont la fréquence varie en fonction du signal de commande. Un diviseur à module variable (106) divise le signal de sortie pour produire le signal de commande de phase. Le diviseur à module variable fait varier son rapport de division en fonction d'un signal de commande de rapport dérivé par un modulateur sigma-delta de second ordre ou d'ordre supérieur (102) en réponse à un signal de commande de fréquence deltaPHI et au signal de commande de phase. Le modulateur sigma-delta (102) écarte les bruits de quantification, qui apparaissent dans le signal de commande de rapport, de la fréquence du signal de commande de phase et de ses multiples. Un synthétiseur de fréquences direct peut être obtenu au moyen du même modulateur sigma-delta et du même diviseur à module variable, en étant conçu cependant de sorte que le signal de fréquence de référence s'applique à l'entrée du diviseur, lequel le divise directement pour fournir la fréquence de sortie désirée.
