Title: Measuring method and measuring device of sub-pulse signal in magnetically transferred recording medium
Inventor: YUZAWA TAKESHI
IPC: G11B20/18
Filed: 2000-07-25
Abstract: PROBLEM TO BE SOLVED: To accurately measure sub-pulse amplitude quickly and easily. SOLUTION: Since a 1st hysteresis value is satisfactorily larger than the amplitude value of the sub-pulse signal is applied, when the peak of a pulse signal is first detected from media; whereon the information is recorded by the magnetic transfer, only the positive/negative peaks of the individual pulses of the original pulse signal are detected (S4, 5). Next, a window to be set at a center of positive/negative peak positions adjacent to each pulse is set (S6) so as to include the sub-pulse signal on a base line; and further, the peak is detected (S7) by the 2nd hysteresis value smaller than the sub-pulse signal amplitude. Furthermore, by using the difference between peak values of the positive/ negative peaks, the amplitude value of the single sub-pulse signal is obtained. Thus, the average amplitude value of all pulses of the single sub-pulse signal included in the measured area is obtained.

IPC: B32B27/00
Filed: 2000-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a decorative sheet good in vacuum moldability, bending processability and adhesiveness without using a vinyl chloride resin sheet.

Title: Control device for vehicle
Inventor: MURAMOTO ITSURO
IPC: B60W10/10
Filed: 2000-08-10
Abstract: PROBLEM TO BE SOLVED: To control preceding vehicle follow-up traveling so that an engine operating point is not apart from an optimum fuel consumption line and achieve optimum fuel consumption. SOLUTION: A continuously variable transmission is set in correspondence with load based on required data and a present change gear ratio is obtained in steps 101 and 102. A maximum shifting speed mechanically determined is obtained in a step 103. A relative speed is obtained and a target inter-vehicular distance for follow-up traveling is calculated in steps 104 to 106, and a target driving force for achieving the target inter-vehicular distance is calculated through steps 107 and 108. The target driving force is corrected by limiting to a realizable range for keeping the optimum fuel consumption line based on the maximum shifting speed in a step 109, and the corrected target driving force is outputted to an engine and a transmission controller in a step 110.  Thus, the vehicle is prevented to forcibly attempt to realize the target inter- vehicular distance with respect to rapid acceleration of the preceding vehicle but follows up with moderate acceleration and achieves the optimum fuel consumption.
