This study surveys the tension differences between Korean domestic and foreign looms and analyses fabric mechanical properties due to warp and weft tension differences using KES-FB system. Paper is divided by two parts. In this 1st paper, fabric is designed as 5 harness satin weave using 75d/36f warp and 100d/192f weft polyester filaments, and is woven by $Omega^\circledR$ rapier loom by Textec Co.Ltd and Picanol$-GTX^\circledR$ rapier loom by Picanol Co.Ltd respectively. These grey fabrics are processed on the same dyeing and finishing processes. Weavability is also analysed by measuring warp tension variation according to the warp position, the relationship between shed amount and the warp tension on one fixed heald frame is surveyed, and the relationship between end breaks and warp and weft tensions is also discussed.

Recently a large number of electronic control devices are abruptly increasing in vehicles as the electronic industry advances. Also the number of wiring harnesses and complexity of wiring is proportionally increased to the devices. A newly developed connector named bridge connector is introduced in this study for the purpose of the wiring structure changes. A wiring structure among distributed control systems by using serial communication is proposed with the bridge connector in this paper. The bridge connector contains a auto-recovery fuse made by PTC thermistor material for the protection of the over-currents on local control devices. The auto-recovery function of the fuse is needed for the maintenance free system in the distributed controls. The PTC fuse characteristics organized in this study is tested and the results are showed in detail for the real application.

In this paper, stack voltage monitoring module is developed which monitor cell voltage of the fuel cell stack and transfer it to the main controller for monitoring fault and stopping drive when the trouble is happened in the fuel cell stack. Especially, the circuit, for monitoring each cell voltage of several hundreds cells in stack, is designed and analyzed. The connector is also developed for making wire harness simple and low cost because wire harness is complicated when the cells are connect each monitoring circuit.

This study analyzed the accidents and researched on risk of the actual condition in roof works. This study revealed that 68% of accidents in roof works occurred on small sized construction sites. And 79% of accidents are caused by fall. It is simply because most laborers do not wear the safety harness and the mounted equipment is not properly installed. According to our research, we realize that most of roof works have some risk of the fall accidents. Most of roof working sites have the danger of falling at ladder and temporary walkway. In oder to prevent accidents in roof works, the basic rule such as wearing the safety harness must be followed.

The Purpose of this study is to investigate the jeogori included in the buddist statue in 1748. The jeogori was similar in shape to excavated costume of Andong Kwon, Papyung Yoon, and Chungyeongunju in 18th century. This jeogori was useful to estimate the interesting process of shape change of jeogori in 18th century. Four different silk fabrics were used in the jeogori. Outer fabrics were satin weave with floral, lattice strip, dragon, and cloud patterns. The ground area was 5-harness warp faced satin and the patterned area was 5-harness filling faced satin. An inner fabric was simple plain weave. Warp and filling yarns of all fabrics in this jeogori had no twist.

In order to investigate the mechanical properties such as tensile, bending, shearing, thickness and weight of the wool fabrics were measured by KES-F system. Samples were classified into blend ratio, weave type, fabric count. Blend ratio was classified into two groups, which are P/W blended fabric (p=63~65%, w=35~37%) and all wool fabric. Weave type was classified into four groups, which are plain, 3 harness twill, 4harness twill, satin. Cloth count was classified into three groups, which are loose, medium, tight. Statistical analysis was performed using T-test, F-test. The results were as follows; 1. There was significant difference in the thickness, tensile, bending, shearing according to the blend ratio. 2. According the weave, there was significant difference in the bending, weight and thickness in the P/W blended fabrics. There was significant difference in the tensile, weight, thickness, bending, shearing, shearing hysterisis (2HG) in the all wool fabrics. 3. There was significant difference in the shearing properties according to the fabric count.

In this paper, various tow parameters such as equivalent tow thickness, amplitude of longitudinal tow and tow intervals were investigated and compared with each other by using microscopic observation to find out the exact deformation patterns between both directions of the fabric structure (Longitudinal and Transverse Directions). Specimens for the observation were taken from draped helmet which is made of fabric composite (Five Harness Satin Weave). From the observation results, it was found that there are different deformation pattern between tow directions and effect of geometric condition on the deformation of the fabric materials during draping process was verified.

Recently an automobile industry is concerned about an automobile wiring harness system. It means that development of component modules is on the increase. An importance of the connector in one part of the modules will be enhanced. A connector is made of P.B.T. (Poly Butylene Terephthalate). PBT is resistant to the high temperature. This paper deals with thermal strain of connector. According as temperature increase, effects of the temperature and thermal strains give an analysis of the deformation using ABAQUS. This apparent thermal strain results actually from the variation of temperature. Being based on this analysis, axiomatic design applies to design parameters of the connector. As compared with CAE analysis, a performance improvement makes certain of the truth of the matter.

This paper describes a machine vision algorithm for inspecting a crimpled terminal. The crimpled terminal is one of wire harness assemblies which transmit current or signals between a pair of electrical or electronic assemblies. The major defect considered is wire exposure on wire barrels. To detect the wire exposure, we develope a multi-layer perceptron in which three features extracted from the image of the crimpled terminal are used as input data. The three features are edginess, variance, and total number of valley points(TVP). The multi-layer neural network has been successfully tested on a number of real specimens collected from a wire-harness factory.
