Filed: 1984-07-31
Abstract: PURPOSE:To run a wagon stably without detecting trees or the like on the outside of a running path by varing the detection length of an obstacle sensor in accordance with the signal of steering control of wheels. CONSTITUTION:The magnetic field from an electric wire 2 for guide to which a low frequency current is flowed is detected by pickup coils 8, and the difference between voltage generated in right and left coils 8 is controlled electrically to drive a steering motor 9. At this time, a steering signal sent from a steering control part 10 to the motor 9 is detected. When the wagon enters a curve on the running path, the steering signal is detected to operate a detection short distance circuit 11, and the circuit 11 acts upon an ultrasonic oscillating circuit 12 of an ultrasonic reflecting sensor 3 to reduce the output of the oscillator 13 and the detection length is shortened. After the wagon passes the curve, a detection long length circuit 14 is operated by the steering signal for a straight in the running path, and the detection length is restored tothe original value. Thus, the unnecessary stop that the wagon is stopped by detecting obejcts on the outside of the running path is prevented on the curve, and the detectable length is extended to secure the safety of collision prevention on the straight.

Title: Magnetic head supporting device
Inventor: YOSHIDA HIROSHI
IPC: G11B21/21
Filed: 1989-06-28
Abstract: PURPOSE:To prevent the danger of falling-off of a head slider even when a hard disk is driven reversely by supporting a supporting spring to a head supporting member while a magnetic head supporting side is tilted in a direction parted from the recording layer forming face of the hard disk sequentially. CONSTITUTION:The free end of a cuntilever supporting spring 2 is slightly tilted in a direction parted from the surface of the hard disk 3 gradually. When the hard disk 3 is slightly driven reversely at the start of a spindle motor, a head slider 4 is drawn in the direction of arrow B with the friction force. However, when the head slider 4 is energized in the direction of arrow B, the cuntilever supporting spring 2 arranged tiltedly generates a clockwise moment around the mounting end to a head base 1b of the supporting spring 2, the free end is energized in the direction of arrow D. Thus, the falling off of the head slider 4 is surely avoided and the possibility of losing the reliability is precluded.
