IPC: H04L12/00
Filed: 1989-12-25
Abstract: PURPOSE:To encode an information signal and to efficiently store the signal in a packet by canceling difference between the number of bits in a code, which is formed by encoding a band signal, and the number of bits to be determined corresponding to the power of the band signal with the number of bits for encoding the other band signal. CONSTITUTION:When the number of bits in the code, which is formed by encoding the band signal, is larger than the number of bits corresponding to the power of the band signal, this difference is complemented by being subtracted from the number of bits for encoding the other band signal. When the number of bits in the formed code is smaller than the number of bits corresponding to the power of the band signal, this difference is added to the number of bits for encoding the other band signal. Namely, the difference namely the excess and lack are canceled with the number of bits for encoding the other band signal. Thus, the information signal can be encoded and efficiently stored in the packet.

Title: Disk driver, error recovery processing method of the driver and disk drive controller
Inventor: KIMURA JUNICHI
IPC: G11B20/12
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To easily detect the error caused by thermal asperity by controlling a recording and reproducing means and executing an error recovery processing without conducting a compensation by a compensating means when an error is detected in a recording and reproducing operation. SOLUTION: An arm electronic circuit (AE) 3 is provided with a signal adaptive filter 3a.

Title: Method for predicting service life of mounting section and solder shape
Inventor: MATSUO TOSHIKAZU
IPC: H01L21/60
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a method for predicting service life of a mounted section by which the optimum solder shape can be predicted through the prediction of the service life of a mounted section and solder shape. SOLUTION: A value n(d-D)/h is calculated by using a height (h) 16 and diameter (d) 17 of a solder 9 after it is mounted, a diameter D 15 of a parts electrode 5, and a correction constant (n). This value represents the shape of the mounted solder 9, and the thermal fatigue life of the solder 9 varies depending on the value n(d-D)/h. Therefore, when a parameter containing the value n(d-D)/h is used, the shape of the mounted solder 9 having the longest thermal fatigue life time can be predicted without the use of numerical simulation.
