The washing machine includes: a body having an inner space of a predetermined volume; a washing tub installed in the body, with a water supply pipe connected to a side of the washing tub so as to supply washing water or a detergent into the tub and with a drain pipe connected to the side of the tub at a position opposite that of the water supply pipe so as to drain used water or used detergent; a cover mounted to a predetermined portion of the body so as to open or close the tub; and an ultrasonic generator installed in at least one predetermined portion of the tub so as to apply ultrasonic vibrations to a laundry contained in the tub.

Abstract: An optical coherence tomography (OCT) probe using lead zirconate titanate (PZT). In the OCT probe using PZT, a sine wave is induced from a vibrator made of a piezoelectric element, so that an image in which the scanning range is increased can be captured due to the vibration of the vibrator. A decrease in the vibration of the vibrator can be minimized by optimizing the position where the base fixes the vibrator.

Abstract: Disclosed herein is an ultrasonic extrusion apparatus which causes resonance of an extrusion die using ultrasonic vibrations, thus reducing friction between the extrusion die and an extrusion material. The ultrasonic extrusion apparatus has an increased number of ultrasonic vibrators provided around the extrusion die in the circumferential direction to increase the vibration output, whereby when extruding a metal material such as a magnesium material, friction between the metal material and the extrusion die can be reduced, thus improving the performance of the extrusion process (preventing a reduction in an extrusion rate, generation of heat, cracking of a product, errors in measurements, etc.).

Abstract: Disclosed is a direct-type driving module of a differential gear for an electric vehicle, which is configured to directly connect a driving shaft of a driving motor to a driving bevel gear without a decelerator. In the direct-type driving module according to the present invention, the driving axel of the driving motor is connected to a driving bevel gear geared with the differential gear through a coupler, thereby easily adapting to the change of a driving axel. In addition, a rotator of the driving motor can be prevented from being compressed or applied with a tensile load due to an external force applied to a driving axel installed in a direct-type driving method, thereby increasing durability of the driving motor.
