This paper descrived housing design in conception of dynamic characteristics. The vibration and noise in power train system of automobile are important on the environment matter. The vibration caused by meshing teeth of gear is transmitted to the gear box faces through shafts and bearings. Shape of housing is used different radius of curvature(R=0 to 80 mm). The velocity responese, sound power and radiation efficency on the surface of gear box are calculated. The sound power and radiation efficency are compared with different radius of curvature.

This study proposes that the Phase Linearization Interpolation is higher efficency than the existed Orthogonal Frequency Division Multiplexing system in the Multipath channels time-varient. Also, it showed that time domain equalization is better than the existed frequency domain equalization about the calculation and efficency for clear Inter Carrier Interference of the doppler effect.

Flat fluorescent lamp(FFL) is used as a light source for LCD TV backlight and is composed of many discharge channels but each channel may not be turned on simultatneouly especially at cold temperature. The simultaneous start of each lamp channels of FFL was accomplished by driving FFL with specially designed voltage and currnet waveforms without sacrificing the inverter efficency.

In this paper, we present the new method for joint aspect inspecting system. We use the image processing and laser maker for light source. We can find the matrial joint status through processing the line pattern which is made by laser maker. To get the line pattern, in first, we did the preprocess of threshold. If the shape of line had over two segments, then the joint status is abnormal. We show our system efficency by experiment on tire facility.

본 논문에서는 ATM 계층에서 GFR 서비스의 공정성 기준을 만족시키고, 효율적인 셀 서비스를 위한 버퍼관리 및 스케줄링 기법을 제안하였다. 시뮬레이션을 통한 성능 분석 결과 기존의 WRR 방식에서 만족하지 못하는 공평성 기준 2(MCR plus equal share)를 만족시킬 수 있었다. 또한 수율면에서도 제안된 알고리즘이 기존의 WRR보다 약 29% 향상되었고 공평성 지표에서는 WRR보다 제안된 알고리즘이 더 우수함을 확인할 수 있었다.

이종접합태양전지는 단결정 실리콘 기판 표면에 고품질 비정질 실리콘층을 적층함으로써 전기의 근원인 전하의 재결합 손실을 줄여 높은 개방전압을 얻을 수 있다는 특징이 있다. 초박형 태양전지는 기존 태양전지보다 뛰어난 광전변환 특성(Photovoltaic characteristic)을 가지고 두께가 얇아 제품 형상 시 자유도가 높아진다. 본 논문에서는 n-type Bare wafer($160{\sim}180{\mu}m$)를 이용하여 $50{\mu}m$의 웨이퍼를 제작하였다. a-Si:H(p)_a-Si:H(i)_c-Si(n)의 광흡수층 구조를 성막하여 cell을 제작하였다. 그 결과 Voc(Open Circuit Voltage)가 0.666, Jsc(Short-Circuit Current)가 34.77, FF(Fill Factor) 69.413, Efficency 16.07%를 달성했다.

In this paper, complex discharge type ozonizer with a screw type electrode has been designed and manufactured for environmental improvement using low power and high efficency ozoniazer. The complex discharge type ozonizer is equipped with three electrodes{central electrode(CE), internal electrode(IE) and external electrode(EE)}. Ozone of the complex discharge type ozonizer is generated by superposition of silent discharge and surface discharge in discharge space as a screw type CE and IE are respectively applied to AC high voltage of inverse-polarity has $180[^{\circ}]$ phase difference, EE is common electrode. In this time, when oxygen has been used as supplied gas, the maximum values of ozone concentration, ozone generation and ozone yield were obtained as 8,334[ppm], 3,249[mg/h] and 65.3[g/kwh].

A mutational alteration in the signal sequence of ribose-binding protein (RBP) of Escherichia coli, rbsB103, completely blocks the export of the protein to the periplasm. Intragenic suppressors for this mutation have been selected on minimal medium with ribose as a sole carbon source. Six suppressor mutations were characterized in detail and were found to have single amino acid wubstitution in the mature portion of RBP, which resulted in the mobility shift of the proteins on SDS polyacrylamide gel. Amino acid changes of these suppressors were localized in several peptides which are packed to form the N terminal domain of typical bilobate conformation of RBP. The involvement of SecB, a molecular chaperone, was investigated in the suppression of signal sequence mutation. Translocation efficency was found to be increased by the presence of SecB for all suppressors. It is likely that the folding characteristics of RBP altered by the suppressor mutations affect the affinity of interaction between SecB and RBP.

This paper describes the design process of three-phase squirrel cage induction moter. stator and rotor were modelled with the result obtained from loading distribution on the provided specification. For proving validity of the result obtained from loading distribution, through Maxwell simulator the first test target values, output and efficency, synchronous speed and etc, were compared with the design result.
