Title: Power steering device
Inventor: SHIRAKAWA FUJIO
IPC: B62D5/07
Filed: 2001-02-09
Abstract: PROBLEM TO BE SOLVED: To improve a steering feeling in detection of an abnormal condition of a vehicle speed signal and in its recovery to a normal condition. SOLUTION: When an abnormal condition in the vehicle speed signal is detected and a stepping motor is rotated to a predetermined retracting position, a rotation speed of the stepping motor is set to 0.2 Vr (step S4). When the vehicle speed signal is recovered to a normal condition and the stepping motor is rotated to a vehicle speed matching position, the rotation speed of the stepping motor is set to 0.5 Vr (step S8). In this way, in detection of the vehicle sped signal abnormal condition, a steering assisting force is changed comparatively slowly, while in the recovery to the normal condition, vehicle speed sensitive control of the stepping motor is quickly restarted.  Therefore, an uncomfortable steering feeling due to a rapid change of the steering assisting force can be prevented from being given to a driver in detecting the vehicle speed signal abnormal condition, and the steering responsiveness can be improved in recovery to the vehicle speed signal normal condition.

Title: Base station designation system and base station designating method in cdma system
Inventor: TAKANO NAOKO
IPC: H04W36/18
Filed: 2001-02-22
Abstract: PROBLEM TO BE SOLVED: To provide a base station designation system, where the number of code sequences used for objects of discrimination by a base station is minimized, so as to enhance the utilizing efficiency of the code sequences and improve the discrimination accuracy.
