Filed: 1990-01-04
Abstract: Une machine à souder automatique est utilisée dans un groupe de soudage interne (30) passant le long de l'intérieur d'une conduite et effectuant les passes de soudure intérieure à la jonction de l'embranchement des conduites (32, 33). Le groupe de soudage interne (30) possède un système de commande électronique comprenant plusieurs ensembles de commande par microprocesseurs (92, 94, 96, 98), chacun d'entre eux effectuant des opérations spécifiques fonctionnelles pour le groupe de soudage interne (30). Le système de commande dirige le fonctionnement de soudeuses internes orbitales (140) pour leur appliquer une vitesse d'avance lente ou nulle au point de départ afin que l'amorçage de l'arc soit très fiable. Après l'amorçage de l'arc, la vitesse d'avance des soudeuses internes (140) s'accélère pour atteindre une cadence élevée pendant la plus grande partie de la passe de soudure. Quand la passe se termine, la vitesse d'avance des soudeuses (140) et la vitesse d'amenée du fil sont réduites brusquement à zéro pour terminer la soudure.

Title: Detecting location of time slot where data begins using pointer in justification or stuffing synchronous tdm
Inventor: KANEKO HIROAKI
IPC: H04L7/08
Filed: 1992-06-29
Abstract: In a synchronous TDM communications system wherein the data is transmitted after being subject to zero, negative or positive justification, a location of a time slot where data having a predetermined length begins, is specified by detecting a pointer.  The pointer, which is included in a demultiplexed channel information, is extracted from the demultiplexed channel information. Further, a pointer value indicative of the predetermined length is detected.  Still further, a justification status is also detected using the pointer extracted.  On the other hand, a timing signal is received which corresponds to the zero justification.  A pointer offset is produced using the timing signal, while another pointer offsets are generated by advancing and retarding the pointer offset by one time slot.  Subsequently, one of the three offsets is selected depending on the justification status.  A comparator compares the pointer offset selected and the pointer value and outputs a signal indicative of the first time slot of the data in the event that the comparison coincidence has been detected.

The container may include a mechanism to enhance the bulk gas transfer rate during the application of the vacuum while still maintaining the desired atmosphere within the container. The container atmosphere may be precharged with gas of a desired composition. In addition, fumigants may also be included therein.      The package is suitable for field packing applications in which the product, such as strawberries, is picked directly into the container surrounded by the cooling collar with the container and cooling collars being placed in an outer box or other receptacle. The modified atmosphere package may be sealed and palletized prior to vacuum cooling.
