Abstract: When a rotary table rotates, a main control section of a multi-tasking machine detects vibration of the rotary table on which a workpiece is mounted based on fluctuation of a position droop computed by a servo system. The main control section computes the arrangement position (the eccentricity amount and the eccentricity angle) of the workpiece with respect to the rotary table based on, for example, the detected vibration, the weight of the workpiece, and the rotation speed of the rotary table. The main control section computes the attachment position of a balancer with respect to the rotary table based on the computed arrangement position of the workpiece. Therefore, a suitable attachment position of a vibration suppressing balancer with respect to the rotary table is easily obtained.

Abstract: A computer-aided learning method and apparatus for a learning user to learn materials inexpensively. Not only does the apparatus provide the user the freedom as to where and when to learn, and the guidance as to what to learn, the apparatus also reduces a significant hurdle to learning—Tuition.

If the user is a learning user, the apparatus allows the user to access information regarding learning materials. If the user is an institute user, the apparatus permits the user to access information regarding at least one learning user. The institute user might be interested to use the apparatus to recruit employees to fill job openings. A learning user pays significantly less than an institute user to access information, so as to encourage the learning user to work on learning materials.
