Japanese Patent JP3354842
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To guide a propulsion object within an almost satisfactory range to a scheduled arrival part by adjusting the discrete distance between a pair of coils. SOLUTION: A reception signal validity discriminating part 9 discriminates that a propulsion object 1 reaches a distance, in which is has been cleared beforehand that the validity of reception signals 4R and 4L is not guaranteed by experiment or the like for each receiving coils 3R and 3L from a relation among a propulsive distance XS, propulsive depth (d), and distance XN from each receiving coil 3R and 3L. Then, the reception signal validity discriminating part 9 discriminates that the validity of the signals 4R and 4L is not guaranteed based on the discriminated result which is generated earlier among its own discriminated result and the judged result of a signal intensity discriminating part 8, generates a reception invalidation signal F, and outputs it to a horizontal direction displacement amount calculating part 7 and a guidance instructing part 6. Moreover, at the time of starting propulsion object steering control, a receiving device is set so that the discrete distance between the coils 3R and 3L can be a maximum by a receiving coil position adjusting mechanism 38, and an operator operates the position adjusting mechanism 38, when display corresponding to the signal F is operated at the instructing part 6 for adjusting the discrete distance between the coils 3R and 3L so as to be short.
