Title: Improved data compression apparatus.
Inventor: O'BRIEN JOHN TIMOTHY
IPC: H03M7/46
Filed: 1990-09-05
Abstract: The improved data compression system concurrently processes both strings of repeated characters and textual substitution of input character strings. In this system, the performance of data compression techniques based on textual substitution are improved by the use of a compact representation for identifying instances in which a character in the input data stream is repeated. This is accomplished by nesting a run length encoding system in the textual substitution system. This structure adds the recognition of runs of a repeated character before the processor performs the textual substituted data compression operation. A further performance improvement is obtained by expanding the alphabet of symbols stored in the compressor's dictionary to include both the characters of the input data stream and repeat counts which indicate the repetition of a character. The handling of these repeat counts by the textual substitution based compression technique is no different than the handling of characters, or certain modifications are made in the handling of repeat counts.

Abstract: L'invention se rapporte à un film résineux utilisé essentiellement dans la fabrication de cartes de circuits imprimés flexibles, ainsi qu'à un procédé de fabrication d'un tel film. Lors de la fabrication de cartes de circuits imprimés flexibles, la carte subit une variation de dimensions au moment où on procède à l'attaque d'une feuille de cuivre (2) selon un motif spécifié après thermocollage de la feuille sur un film résineux (1). Pour réduire cette variation des dimensions, un rapport (a/b) entre le coefficient d'expansion linéaire (a) du film résineux (1) dans la direction d'avance mécanique (direction MD) et le coefficient d'expansion linéaire (b) de ce même film dans la direction (direction TD) perpendiculaire à la direction d'avance mécanique est réglé sur une valeur égale à 0,2 ou davantage mais inférieure à 1,0, et le coefficient d'expansion linéaire dans la direction d'avance mécanique (direction MD) est reglé sur une valeur comprise entre 0,4 et 2,0 x 10-5 °C-1. On utilise comme film résineux un film de polyimide représenté par une formule générale spécifiée et contenant un pourcentage de période d'identité égale à 90 ou plus. En outre, pour produire un tel film résineux, on fait subir au film (1) un allongement de 1,0 à 1,5 fois dans la direction d'avance mécanique (direction MD) et de 0,5 à 0,99 fois dans la direction (direction TD) perpendiculaire à la direction d'avance mécanique.

Abstract: There is provided a transient electromagnetic method and apparatus for inspecting objects using a moving sensor. The apparatus (13) includes a sensing portion (27) which has a transmitting antenna (29) and at least one receiving antenna thereon (31). The sensing portion (27) is located adjacent to the object which is to be inspected such that the antennas (29,31) are adjacent to the object. The sensing portion (27) is moved along the object at the same time as the transmitting antenna (29) is inducing current in the wall and the receiving antenna (31) is producing a receiving signal of the induced current diffusion in the wall. Because the antennas (29,31) are moving during data acquisition, the speed of inspection is increased. The data is then interpreted to determine the thickness of the object. <IMAGE>
