Production technology in traditional industries is inherited in the form of " remember while watching the back of the master." It is a knowledge base of the form of "tacit knowledge", and they need to be formalized by the power of science and technology. Movement of experts is recorded using an infrared camera. The position in the space of the marker affixed to each part of the body of the subject is acquired as digital data. In this report, Kyoto bow showed examples that formalized the tacit knowledge of manufacturing in traditional industries. Kyoto bow is a Japanese bow often used for archery enthusiasts. Mr. Shibata is the 21st bow priest. In order to elucidate the tacit knowledge, he possessed, vibration tests and bending tests were conducted. Test results proved that materials with high modulus of elasticity were chosen when Mr. Shibata chooses materials.

There are many traditional technologies that have much knowledge to fabricate products in Japan. Such a knowledge is so-called technical intuitions and sensitivities. The craftsmen apply the technique for regenerating some traditional products and we defined the knowledge as “implicit knowledge.” The concept of this study is to scientifically analyze the implicit knowledge of those technologies. Here, the implicit knowledge would be traced from the contemporary view point. Thus, the knowledge can be applied to the modern technology which is adaptable to the market requirements. Finally the traditional technology retailed with the advanced technology many create a new technology. Kyokabe is one of Japanese clay wall for the traditional architectures. The clay wall consists of clay, sand and straws. Straws obviously play a reinforcement, thus Kyokabe can be treated as a composite material. Straws are immersed in the mixture of clay, sand and water for some period of time. The implicit knowledge which Plasterers (masters of Kyokabe) have acquired is that increase in the straws quantity results in increase in compressive strength and increase in the time improves workability in drawing. In this study, the implicit knowledge is scientifically resolved. The effects of the quantity and the immersion time on the compressive properties and workability of Kyokabe were also investigated.

Braids have been applied to various components for over one thousand years. Binding, bundling and hanging are listed in the representative uses of braids. The braids have characteristic mechanical properties, low modulus, large deformability, variable Poisson's ratio and low stiffness under flexural and compressive loads, and so on. Evaluation method of the braid properties has not been established. In order to clarify mechanical properties of the braids under the initial tensile loading quantitatively, an evaluation method is proposed in this study. By the application of the proposed method to three kinds of glass fiber braids, effects of braiding structure on the mechanical properties are discussed. Therefore the valid tensile testing method for evaluation of the braid properties could be proposed.
