Title: Travelling course setting device for self-travelling vehicle
Inventor: KAMIMURA KENJI
IPC: G05D1/02
Filed: 1989-10-25
Abstract: PURPOSE:To recognize a work area easily by setting a travelling course by the work area which is recognized based on the position data of the optical reflecting means which reflects light to the light incident direction. CONSTITUTION:A self-travelling vehicle 1 possesses a controller which contains a calculating means which calculates the direction of respective reflectors 6a-6d arranged around the work area to the advancing direction of the self-travelling vehicle and the distance from respective reflectors 6a-6d. The direction is calculated by this controller based on the rotation angle of a rotation table 4 at the upper part of the car 1. Further, the distance is calculated based on the difference between the phase of a light beam injected from a light emitting device 2 and the phase of a reflected light returning from the reflectors 6a-6d to a light receiver 3. And, the travelling course is set in the work area recognized based on the calculated position data of the optical reflecting means 6a-6d. Thus, the work area can be recognized without arranging the many numbers of reflecting means 6a-6d.

Abstract: PURPOSE: To directly measure the depth of the defect of a material to the degree of 1 mil by providing means for conducting relative motion between the material and a pair of impedance elements, an oscillator connected to the elements, a pair of phase detectors, and a means for comparing the output signals in a material defect detector. CONSTITUTION: An impedance bridge 10 has impedance elements 12a, 12b and probe coils 14a, 14b. The connecting point of the coils 14 is connected to a reference voltage. The connecting point of the elements 12 is driven by an oscillator 6. Magnetic flux lines generated from the coils 14a, 14b form an eddy current in an adjacent conductive substance. The signals of the coils 14a, 14b are applied to phase detectors 30a, 30b, and compared by a differential amplifier 34. When there is not the damage of an object near the coil 14, the bridge 10 is balanced so that the signals to the amplifier 34 are equal. At the time when there is the damage near the coil 14, they become unequal by the change of the eddy currents. Thus, when the probe is scanned to cross the defect, the output of the amplified 34 is changed from zero, a positive value, a negative value to zero. Thus, the depth of the detect can be directly measured.
