With the wave maker and the pool

摘要

PROBLEM TO BE SOLVED: To synchronize respective wave-generating devices to continuously generate waves with various specified patterns, by controlling respective correcting motors of phases through a phase-discrimination device, on the basis of the output of respective pulse generators, the output of original point signal generator, and the output of a phase-difference setter. ;SOLUTION: This device is constituted of a speed change gear 3 altering the phases by a phase-correcting motor, a pulse generator 5 detecting the revolution of the shaft and outputting a specified number of pulses, a speed reducer 6 connected to the shaft of the speed change gear, a crank mechanism 7 connected thereto, an original point signal generator 8 output thereby, wave- generators S₁-S₃ connected to the crank mechanism, etc. Since a phase- discriminator (controller) 11 controlling respective phase-correcting motors on the basis of the output of a phase-difference setter (input part) setting phase- differences drives motors 1 of respective wave-generators and servo-motors 4 thereof and the original point signal generator 8 controls the revolution number of the servo-motors 4 to synchronize respective wave-generators, whirlpools do not arise at the nearby position of the wave exit and hence, various kinds of waves can be continuously generated.;COPYRIGHT: (C)1997,JPO
