Title: Error correction decoding device and its method
Inventor: NAKAMURA TAKAHIKO
IPC: G06F11/10
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To decrease the rewriting frequency of coefficients of a divided polynomial and a dividing polynomial and to increase the speed of error correction decoding processing by calculating the coefficient of a quotient polynomial via the arithmetic part of Euclidean algorithm and by means of two coefficients of high orders of both divided and dividing polynomials, when the difference of degrees is equal to 1 between the divided and dividing polynomials. SOLUTION: The arithmetic part of Euclidean algorithm 2000 calculates error correction polynomials, including an error numeric polynomial, an error position polynomial, etc., from a syndrome generated at a syndrome generation part 1000 and by means of the Euclidean algorithm. Then the error numeric and error position polynomials are sent to an error correction part 3000, in which the errors of both polynomials are corrected. When the difference of degrees is equal to 1 between the divided and dividing polynomials, the part 2000 performs a division operation with high orders and by means of two coefficients. Thus, it is possible to decrease the rewriting frequency of coefficients of both the divided and dividing polynomials and to increase the speed of error correction decoding processing.

Abstract: PURPOSE:To clarify the electrically connected state, and make a connector difficult to be in the incompletely connected state. CONSTITUTION:When a charger-side connector 20 is pushed onto the side of a car body-side connector 10, the restoring force pushes back the charger-side connector 20 since the pushing inclined surface 25b of a spring plate 25 is laid in the state getting on the pushing inclined surface 17a1 in a deep hole 17 up to the middle. Namely, since the connectors are mutually separated up to the middle when the hand is released, the electric connection is also interrupted. On the other hand, when the pushing is conducted until the guide part 25a of the spring plate 25 gets over the top part which is the connecting part between the drawing inclined surface 17a2 and the pushing inclined surface 17a1 in the deep hole 17, it works to draw the charger-side connector 20. Namely, although the connector 20 is pushed out up to the middle, it is conversely drawn when exceeds this, so that the mutual connectors are naturally combined to each other when the hand is released, and also electrically connected in the perfect state.
