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.

Abstract: Provided is an electric field-vibration generating transducer having a piezoelectric material of a high degree of displacement, and a manufacturing method thereof. 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: An after-treating apparatus of exhaust gas and a catalyst device installed therein is disclosed. The after-treating apparatus of exhaust gas primarily removes the exhaust gas in a first filtering device and a second filtering device, and secondarily purifies within the catalyst device. The first filtering device and the second filtering device are controlled by opening and closing a valve through a time control part. That is, when particulate of the exhaust gas is collected in the first filtering device, the second filtering device burns the collected particulate by means of an electric heater. Also, the catalyst device is prepared by wash-coating an active substrate on a honeycomb, the active substrate being produced by supporting platinum, nickel, and promoter on a supporter of alumina and chromic oxide.
