Title: Controller of magnetic levitation slider
Inventor: NAKASEKI TSUGUTO
IPC: B60L13/06
Filed: 1985-04-19
Abstract: PURPOSE:To float or land a slider without shock by gradually varying the reference position set value of a servo control system at levitating or landing time of the slider. CONSTITUTION:A servo control system 13 controls a power source to be supplied to a control coil 12 of upward and downward control electromagnet 7 in response to the difference between the detected voltage of a position sensor 8 and the set voltage V output from a reference position voltage setter 14. When a switch S is closed, a capacitor C is charged through a resistor R3 to a power source voltage at the constant time constant. Accordingly, a slider 4 is slowly levitated from the landing state to a normal levitation state on the basis of the time constant determined by the size of the capacitor C. When the switch S is opened, the load of the capacitor C is discharged through a resistor R4 and a transistor Tr. As a result, the set voltage V is gradually increased to land the slider 4 on rails 3.

IPC: B62D5/065
Filed: 1981-06-03
Abstract: PURPOSE:To stop an electric motor when steering power does not need to be supplemented, by driving the motor only for a prescribed period of time. CONSTITUTION:When a transmission is not in the low and reverse positions, the first OR circuit 22 of a controller 17 does not supply an output signal S5 because a low signal S1 and a reverse signal S2 are not applied to the circuit 22.

Abstract: PURPOSE: To avoid abnormal tension on tape at capstan pressing, by controlling the torque of reel so that a given acceleration can be caused to the uppermost circumference of the reel winding diameter through the detection of the tape winding diameter of reel.  
     CONSTITUTION: The photo sensing elements 28, 29 opposing to the light sources 26, 27 produce the output corresponding to the reel winding diameter. The output of the steadystate torque signal generation circuit 30 at the supply side and the transient torque signal generation circuit 32 at the supply side gives a given tape acceleration independently of the winding diameter of the reel 11. Until the tape speed reaches a given speed, the Schmitt circuit 36 detecting the tape speed operates the switch circuit 34 to give the output to the output signal reel drive circuit 39 of the addition circuit 37 to produce the torque corresponding to the winding diameter of the reel motor. Accordingly, the reel is driven with a given acceleration independently of the winding diameter, and the pinch roller is pressed on the capstan when it reaches a given tape speed to avoid abnormal tension on the tape.
