This paper proposed the optimal algorithm of grinding system and the method to realize it. The optimal function was proposed in order to design the optimal grinding process. DE(Differential Evolution) algorithm was used to obtain the selective optimal function. The realization of algorithm was implemented by LabView software used widely at industrial field and the proposed algorithm was verified for through computer simulation. The result of the proposed algorithm can be used for the guide line of the grinding process.

RFID reader platform with self-diagnosis function studied in this paper has an automatic state recognition function, a report function, and an automatic upgrade function. Also, since it uses frequency operation policy in multiple reader environments, it will be frequently used in the large operation environment and multi-readers environment. Therefore, the technology can meet the demands not only in the domestic RFID market, but in the global market.

The demand of bike increases eco-friendly as the mean of transportation but domestic production basis becomes sluggish. In this study, the design analysis of horizontal and vertical frame is performed on the model which is proposed as the bike of new concept in conjunction with public transport system. As the result, the structural analysis is conducted on the main frame of urban bike used with cast magnesium alloy. As the vertical load of 150 kg is applied, the design technology insures that maximum stress less than 70 MPa is obtained.

ID registered in RFID tag is written as a binary or code form and interpreted by RF reader. It must be changed to FQDN structure for the internet service. FQDN(Fully Qualified Domain Name) form also must be resolved during the several steps in the application service networks. In this paper, we studied the technical issues and proposed the resolution mechanism fur the sample ID system. As a sample ID, we applied ISBN to RFID system.

The single phase switched reluctance motor has simple, robust structure and economical drive system. So, it is useful to apply in the industrial and home applied machines. Especially, the single phase induction motor, used much in field, has a low efficiency and control ability. For the replacement of it, the single phase SRM is presented. In this paper, the design and characteristics of single phase SRM considering the rotor shape will be presented in the base of general electric motor design method and poly phase SRM design method.

This paper addresses the prediction of the material property continuities of a microstructure. Prediction was made by measuring the dynamic responses distribution of the fabricated materials used in the microstructures. When these distributional material properties were used in estimating the mechanical performances of microstructures, the differences between the computer simulation and the experimental result of microstructures could be reduced and their reliability design could be made.

The objective of this study is to identify the priority of elements for effective implementation of MES in small and medium-sized manufacturing enterprises trying to develop into smart factories. For this purpose, the Delphi method and the Analytic Hierarchy Process(AHP) mothod are applied. As a result of the study, the cooperation of the members in the supply chain is the most important factor for small and medium-sized enterprises in order to survive in the global competitive environment. Therefore, the enterprises need to make various efforts to create synergies through the technical strength of suppliers and the cooperation in the process of introducing and operating MES.

While graduates of Japan's technical high schools might demonstrate skills in a given specialty, they would be hard-pressed in any attempt to pass national universities' notorious entrance examinations. In a collaborative effort begun in 1994, the faculties of engineering at Niigata, Nagasaki, and Toyama Universities set about the task of preparing entrance examinations, and a general curriculum geared to the needs and educational backgrounds of these students, offering them supplementary lessons. While the larger project officially ended in 1999, we are carrying the research forward in Niigata University.
