Title: Travel control device of electric motor vehicle
Inventor: TANAKA SHINOBU
IPC: B66F9/24
Filed: 2001-04-05
Abstract: PROBLEM TO BE SOLVED: To reduce fluctuation amplitude of a speed command value when traveling on a bad road. SOLUTION: A period of vibration F of a driver is derived from output of a limit switch (S1). Whether or not to travel on the bad road is determined from the derived period of vibration F (S2). When a road is not the bad road, first delay time Δt1 is set as delay time of a speed command (NO of S2, and S3). When the road is the bad road, second delay time Δt2 larger than Δt1 is set as delay time of the speed command (YES of S2, and S4). The speed command value according to an operation quantity of an accelerator pedal by an accelerator detecting sensor is derived (S5). The derived speed command value is outputted to a traveling motor by delaying by the delay time set in the Step S3 or S4. The traveling motor is controlled on the basis of this speed command value (S6).

Title: Device and method for evaluating quality of regenerated signal, device and method for regenerating data, and recording data and method therefor
Inventor: FUJIMOTO KENSUKE
IPC: G11B20/12
Filed: 2001-04-11
Abstract: PROBLEM TO BE SOLVED: To obtain accurate evaluation values by measuring regenerated signal quality evaluation value, only in regions which have no defects. SOLUTION: The number of times for detecting the regenerated signal quality evaluation values is counted by a counter 107 and is integrated by a register 103 for each small interval shorter than a processing unit of a CPU for controlling a device. When a defect is detected on a disk, a defect detection signal is extended between the small interval detecting the defect and the next small interval by registers 113 and 114. The values integrated in the register 103 are written in a register 104 for each small interval. The values in the register 104 are integrated in a predetermined number of times in a register 106 by the extended defect detecting signal. This value is used as a final averaged evaluation value.  Since the integrated value for the small interval detecting the defect and a small interval immediately, before the small interval is made invalid by the extended defect detecting signal, the averaged evaluation value can be obtained, without being influenced by the defect on the disk.
