Plasma Surface Treatment of Milled Carbon Fibre in a Fluidized-Bed Reactor. (1998)

Kawamura, H., Okubo, T., Kusakabe, K., Morooka, S.

Milled carbon fiber has a bright prospect because it is suitable for extrusion of moulding. Although the strength of carbon fiber composites depend on the interfacial adhesiveness between fiber and...

Study of cancer mortality by grid square method.

Okubo, T

The grid square method as used in Japan has been standardized by the government, by use of the lines of the earth's latitude and longitude. The basic unit covers an area of approximately one square...
