Title: Steering device for unmanned carrier of magnetic guidance type
Inventor: MUKOGASA YUKIO
IPC: G05D1/02
Filed: 1992-07-09
Abstract: PURPOSE:To ensure the steering control of an unmanned carrier along a magnetic guide tape with high safety by suppressing the influence of the disturbance caused by the magnetic foreign matters like the iron scraps, etc., mixed in the concrete floor of an unmanned carrier traveling route. CONSTITUTION:A bit detection type magnetic sensor 3 mounted on an AGV detects a magnetic guide tape 1 laid on a floor surface 2 along an unmanned carrier traveling route. Then, a steering device of the unmanned carrier of a magnetic guidance type performs the steering control of the unmanned carrier based on the detection signal of the sensor 3. A delay circuit 6 consisting of an LPF is connected to the output sides of the magnetic detection elements #1-#3 and #8-#10 arranged at both sides of the sensor 3 among those elements #1-#10 of the sensor 3. Thus, the output response is delayed for the detection element that reacted to a magnetic foreign matter P existing at the periphery of the tape 1 during traveling of the unmanned carrier, and the influence of the magnetic disturbance is eliminated and the steering performance of the unmanned carrier is improved.

Abstract: PURPOSE:To measure the DC voltage with high accuracy by providing an analyzer having the same characteristic as that of a polarizer for allowing a light beam outputted from a Pockels effect element to transmit through and a photodetector for photodetecting a transmission light of the analyzer and comparing it with known light intensity. CONSTITUTION:A laser light emitted from a laser light source 1 is inputted to a Pockels effect element 5 through a polarizer 2, a lambda/4 phase shifter 3 and a chopper 4. To this element 5, an electric field by a DC voltage 10 to be measured is applied through electrodes 6, 7, therefore, a circularly polarized light generates a Pockels effect. In this case, the circularly polarized light is inserted through the element 5 as an intermittent light of a frequency (f), therefore, it is outputted as an elliptically polarized light whose compression is different by magnitude of the voltage 10. Thereafter, by allowing it to pass through an analyzer 8, it becomes a linearly polarized light by which only a light beam in the polarized light direction of the analyzer 8 is allowed to pass through, and light intensity of the linearly polarized light is measured by a photodetector 9. Subsequently, in the photodetector 9, it is compared with light intensity corresponding to a known voltage measured in advance, and a voltage of the voltage 10 can be measured.
