Deformation control of a silicon-wafer slicer cutting a crystal ingot is studied analytically. The thin rotating blade is clamped at the outer boundary and prestressed in the radial direction, while the inner periphery is subjected to stationary, distributed in-plane and lateral slicing loads from the workpiece. The deflection of the blade is obtained analytically by introducing the multi-model expansion method, further applying the Galerkin method to the governing equations of the system. Numerical results are presented for an actual SUS 301 blade cutting a 6"-diameter silicon ingot at a speed of 1550 rpm. Two control schemes that maintain the flatness of the rotating blade are examined in detail. In the first scheme, a pair of concentrated lateral forces are applied to the blade to reduce the blade deflection. In the second scheme, a pair of moments are also applied to the blade to improve the flatness of blade. Simulation results obtained show that the application of control moment is more effective than the simple lateral forces to the improvement of flatness of the slicing blade.

This paper surveys end-of-life strategies currently used in the electronics and appliances industries and identifies product characteristics that guide designers to specify appropriate strategies. The survey indicates that important characteristics are wear-out life, design cycle, technology cycle, functional complexity, number of materials, and number of parts. Two key characteristics, wear-out life and technology cycle, serve as factors to categorize products' appropriate life-cycle scenarios. The categorization leads to a methodology that guides product designers to seek environmentally friendly designs, and to identify opportunities for developing new recycling technologies. Further, an application of quality function deployment (QFD) as a design support tool for helping design engineers early in the product design based on appropriate life-cycle strategies is proposed.

持続可能社会像の議論のため、「持続可能社会シナリオ」が盛んに描かれているが、文章の合理的理解が困難であり、また、シナリオ作成の計算機支援も十分ではない。以上の問題を解決するため、本研究は、論理構造に注目したシナリオ表現方法論、シナリオ作成の計算機支援方法論を提案し、これらを実装したシナリオ作成・分析支援システム「Sustainable Society Scenario (3S) Simulator」を開発した。さらに実行例として、持続可能社会における製造業のシナリオを作成した。
