Abstract: Provided is a piezoelectric single crystal comprising an internal bias electric field, a method of manufacturing the same, and piezoelectric and dielectric application components using the piezoelectric single crystal. The piezoelectric single crystal shows that as a change in each composition of [A] site ions, [B] site ions and [O] site ions from a perovskite type crystal structure ( [A] [B] O3), and oxygen partial-pressure during heat treatment in terms of a manufacturing process are controlled, while maintaining the inherent high dielectric constant and piezoelectric constant, the high internal bias electric field (EI) characteristic essential for the electrical stability of the piezoelectric single crystal is simultaneously satisfied. Therefore, piezoelectric application components and dielectric application components using the piezoelectric single crystal having excellent characteristics can be used in a wide temperature range and operating voltage conditions.

The electric field-vibration generating transducer lowers the cost of production through miniaturization simultaneously with realizing excellent generating characteristics of the electric field-vibration generating transducer based on high efficiency and low voltage driving because the piezoelectric material of the high degree of displacement (high strain piezoelectrics) having a high piezoelectric constant (d33=1,000 to 6,000 pC/N), a high dielectric constant (K3T=6,000 to 15,000) as well as a low dielectric loss (tan ?<2%) is applied thereto, so the electric field-vibration generating transducer may accelerate the movement of a material, a chemical action, and a biological reaction, and may be applied to a medical device for the purpose of treatment for tumors aimed at human bodies and animals.

Abstract: A front airbag including a sub-string and a vent. The front airbag attenuates impact in order to provide protection to a child or an occupant in an abnormal position on a passenger seat. Upon a vehicle collision, the front airbag discharges internal air through a vent provided at the lateral surface of the front airbag, if the front airbag is not inflated at the front, but is instead laterally inflated. The front airbag includes a main tether provided at a central portion of an airbag cushion, a vent selectively discharging air to an outside from the front airbag, and a sub-string, connected to and between the main tether, to control opening/closing of the vent part.
