hmmm, this was a educational task for Mr. Suzuki at that time... Antway, I've not known this page is linked to other Univ's page. It is a work of Osaka prefecture University, and it belongs to her, I suppose. Of course, you can use or improve it by your own risk. However, if anyone wants to link such a property, I suppose, s/he should contact with the original author... Kenji
