摘要： The invention relates to a tape transport mechanism in which two reels are respectively driven by different motors, thereby transporting a magnetic tape from one reel to another reel by passing through the portion of a read/write head without any variation in tension. At the initial stage to transport the magnetic tape, an acceleration time from a stop state of the tape until a tape speed reaches a reference speed and an average tension deviation to be applied to the magnetic tape during this time are obtained. Correction values to correct variations in run characteristics of two reel drive systems are calculated by use of the acceleration time and the average tension deviation. Upon next and the subsequent magnetic tape transport, currents to be supplied to the motors to drive two reels are controlled by use of the drive current command values corrected by those correction values.

摘要： A remote surgery supporting system and a method thereof for presenting realism control data generated by realism control data generating means 101 from image data from work environment data detecting means 104 and measurement data processing means 118 and from force and proximity data. While seeing this presentation, the surgical operator inputs actions through action command inputting means 114 and following to that, diseased tissue manipulating means 102 executes a work to a diseased part 125. Manipulation force of each surgical operator from manipulation command generating means 103 and force reflection from the diseased part 125 are combined and presented to the action command inputting means 114. Thereby, a plulality of surgical operators can perform the surgerical operation while seeing the realism control data and sensing the manipulation force of other surgical operators and the force reflection from the diseased part. Thus, a master/slave type remote surgery supporting system which allows a plurality of surgical operators to perform a surgical operation which requires many degrees of freedom can be provided.

摘要： A magnetic head is provided in a tape transport path along which a magnetic tape is transported from one reel directly to another reel. In order to record or reproduce data to or from the magnetic tape with the magnetic head while the magnetic tape travels, it is necessary to stabilize a tape velocity at the magnetic head position to a desired velocity. The tape velocity at the magnetic head position is determined based on tape velocities at the respective reel positions, a tape path length from the head to one reel and a tape path length from the head to the other reel, and a closed loop control is effected by using the tape velocity at the magnetic head position to match the tape velocity to a desired velocity.

摘要： PURPOSE: To perform an adaptable correction within a short time by deciding an appropriate correction value while considering the causal relation of the characteristic difference and correction value between each reel driving system. CONSTITUTION: At the time when the movement of a magnetic tape 1 is started, the time till the speed of one reel 6 or 7 attains a predetermined reference speed from the stopped state is measured. The average tension error of the magnetic tape 1 in the measuring time is obtained, and the acceleration error of two reel driving systems are respectively calculated from two parameters of the measuring time and the average tension error, then the driving command is corrected against two reel driving systems so as to eliminate this acceleration error. By driving the tape in the manner of obtaining the driving command to compensate the characteristic error of two reel driving systems, the stable tape transfer is realized within a short time.

摘要： PURPOSE:To prevent the damage of a tape at the time of threading by optimizing a tape feed speed and making a load applying to the tape constant. CONSTITUTION:In a threading mechanism transferring a reader block 4 of a tip of a magnetic tape 3 from a supplying reel 2 to a take up reel, a turning angle is detected by a turning angle detector detecting a turning angle of a motor 27 for driving threader arm 6, an angle detector detecting an angle of a link mechanism constituting the threader arm 6, and a tape tension detector. And a transferring speed of a tip of the threader arm 6 is obtained from length of the threader arm 6 and the turning angle of the threader arm 6. A measured speed of the tip of the threader arm 6 is controlled by a motor driving the threader arm 6 so as to be made an arbitrary speed.
