Provided is an ultrasonic generator with an adjustable ultrasonic focusing depth. The ultrasonic generator with an adjustable ultrasonic focusing depth includes a cartridge housing in which an ultrasound generation portion generating ultrasonic waves is provided, a hand piece in which the cartridge housing is detachably mounted, the hand piece having a first actuator thereinside, and a main shaft to which the ultrasound generation portion is coupled so as to reciprocate in a horizontal direction, parallel to the bottom of the cartridge housing and a vertical direction, perpendicular to the bottom of the cartridge housing. One end of the main shaft is coupled to one end of the first actuator of the hand piece, and an other end of the main shaft is located inside the cartridge housing. The hand piece includes an adjustment portion adjusting an ultrasonic focusing depth of the ultrasound generation portion.

The present invention relates to a chrome compound composed of non-coordinating anions and a trivalent chrome cation, a reactant of the chrome compound and a bidentate ligand, an ethylene oligomerization reaction catalyst system using the chrome compound and the reactant, and a method for preparing an ethylene oligomer using the catalyst system. Through the above conformation, the present invention can selectively produce 1-hexene and 1-octene with high activity while omitting the use of methylaluminoxane (MAO), and can provide an ethylene oligomerization process more suitable for mass production.
