The optical reflection and the insertion loss department measurement system are composed of the optical direction coupler which is deriving the optical transmission of a message part and reflected light to the department of sphere optical. The optical technology that can measure microscopic optical to the present 0~ -60㏈m and the technology that can derive the stable laser are guaranteed, and in a mass production step, the uniformity part is a problem that should be solved for measuring the different optical spare parts, and the part can be solved sufficiently through the algorithm of repeat error modification and moving average arithmetic way. In this paper, the source used the distributed feedback laser diode when λ = 1310㎚, λ = 1550㎚, and the receiving optical department used InGaAs pin photo diode. The measurement scope was 0 ~ - 60㏈m for the optical reflection loss and insertion loss, and the disjointing was 0.01㏈, and the stability displayed 0.1㏈/h.

Power steering gear is the part of an automobile. That converts circular movement of steering wheel into lateral movement of rack for changing driving direction. Recently power steering gear gets more common. A Korean company manufactures a speed sensitive power steering gear, which provides variable steering feel depending on speed of the car. However, the Broens company in Australia produces and exports the test equipments for manufacturing power steering valves. Some Korean companies import the test equipments from Broens and the maintenance cost gets increasing. The purpose of this study is development of the valve balance tester to measure the valve torque of the power steering gear. This study designed and manufactured a chuck and a jig of the valve balance tester to take hold of the power steering valve using CAE analysis.
