summary：
In this talk, based on mathematical studies in the research and development of new devices and materials in Canon Inc., I show how mathematics plays important roles in manufacturing industry. As their examples, an electric conduction problem in terms of percolation theory, and a problem of computational method in computational fluid dynamics (CFD) are illustrated. On the studies of the conductivity as a percolation phenomenon, I mention that the industrial requirements to support a design of materials bring novel viewpoints and interesting mathematical facts to us. On the studies of the computational method in CFD, I show also that primitive insights based on singularity theory and abstract description of the fluid dynamics in terms of diffeomorphism yield a novel algorithm to analyze behavior of liquid in inkjet printers numerically. Finally I state that the collaboration between university and industry are quite crucial in mathematical analysis even for manufacturing industry.
