Minimization of the heating up of a magnetostrictive element of a ultrasonic exciter and method for producing

摘要

The invention relates to essential elements of the ultrasonic oscillator and a manufacturing method in an ultrasonic sterilizer development task.; More specifically, the magnetostrictive element (磁 歪 素 子: magnetostrictive element) and a wave guide rod: According to the bonding method of the (導 破 棒 wave guide), with minimal heat input to the furnace (furnace) magnetostrictive element, instead of the heating method under existing pressure conditions, an ultrasonic transmitter and a method of manufacturing the same.; In manufacturing the ultrasonic oscillator applicable to an ultrasonic sterilizer, when bonding the magnetostrictive element and the wave guide rod are molten at a temperature of 575~590 ℃ range Al-Si alloy and has a tensile strength of 230-250 17~25㎏ / ㎟ melting at ℃ range and with minimal heat input of a magnetostrictive element, characterized in that for joining the magnetostrictive elements to the bonding material of the two kinds of Sn-Ag alloy having a tensile strength of 10~15㎏ / ㎟ after creating the wave guide rod molten film the method of the ultrasonic transmitter.
