Title:
ULTRASONIC TREATMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/178436
Kind Code:
A1
Abstract:
An ultrasonic treatment system which comprises a calculation unit for calculating the relationship between the amplitude of a vibrator unit when ultrasonic vibration has been generated, and the current supplied to an ultrasonic wave generation unit, said relationship being calculated on the basis of both the time elapsed since the time the vibrator unit was manufactured, and the number of times vibrator unit heat processing has been performed. An ultrasonic treatment control unit comprises a current value setting unit for setting the current to a suitable current value that causes the amplitude of the vibrator unit to be a target amplitude, the current being set on the basis of the relationship, calculated by the calculation unit, between the amplitude of the vibrator unit, and the current.
