Title: Systeme isolant a champ electrique calibre pour machine dynamo-electrique
Inventor: YOUNSI A KARIM
IPC: H02K3/04
Filed: 2001-09-06
Abstract: L'invention concerne un système isolant de mur de base utilisé dans des machines dynamo-électriques porteuses de tensions supérieures à 4 kV et, de préférence, de l'ordre de 13,8 kV, ou plus. Le revêtement isolant du mur de base comprend deux couches isolantes enroulées sur les conducteurs de l'enroulement haute tension. La première couche isolante présente une première permittivité supérieure à la permittivité de la seconde couche isolante enroulée sur la première couche isolante. On obtient par conséquent, à la jonction entre la première et la seconde couche, une augmentation marquée du profil du champ électrique dans le revêtement isolant du mur de base. Cette augmentation du profil du champ électrique génère dans le champ électrique adjacent au conducteur une magnitude maximale inférieure à celle des systèmes isolants classiques. La réduction de la magnitude maximale du profil du champ électrique local dans le revêtement isolant du mur de base permet d'améliorer la durée de vie du revêtement isolant et, par conséquent, le conducteur électrique, tout en permettant en même temps une réduction de l'épaisseur du revêtement isolant du mur de base.

Filed: 1989-11-24
Abstract: ERROR CORRECTION AND DETECTION                   APPARATUS AND METHOD          Abstract A decoder is arranged to operate as a single-bit error correction circuit (ECC) and as a multiple-bit error detection circuit (EDC). The decoder starts and remains in the ECC state as long as no errors are detected in a received data message. When an error is detected or corrected in a received data message, the decoder switches to the EDC state where it remains as long as errors are detected in the received data message. When no errors are detected in the received data message, the decoder switches back to the ECC state. In a generalized multistate decoder, switching occurs from one state to another state, each state having a different error correcting capability, in response to a predetermined number of errors corrected or detected in the received data.
