A sun visor has been used only for the purpose of interrupting direct sunshine. Investigation, therefore, has not been made to be on the feeling of touch of the sun visor. In this study, the feeling of touch of sun visor installed in the present automobile was investigated. To clarify the relation between the sense of touch and the mechanical and physical quantity of the sun visor, prototype products of the sun visor of the same shape were made. Surface characteristics and cold feel characteristic of materials were measured by the KES system. In addition, we investigated the relation between the surface property and the sense of touch of various materials. The correlation between favorability and WC, RC, SMD was high on the sun visor prototype. As a result, it was clarified that materials whose surfaces were very smooth and soft were favorable. Those materials consist of leather and moquette. Conversely, the material sensed hard was not favorable. The relation between the mechanical and the physical properties of various materials, and the favorability was able to be approximated by the equation (1).<BR><I>Favorability=2.482+0.02791LC+0.293WC-0.264RC+0.0688MIU-0.0966MMD+0.0253SMD-0.0288qmax</I>(1)

Microporous carbons were produced by carbonizing and activating bamboo (phyllostachys heterocycla). Carbon dioxide was used as an activating agent. Also the activated carbons were produced using bamboo carbons with less potassium fractions. The potassium fractions are mainly distributing in the middle lamella that connects the adjacent cell walls of bamboo. The micropore distribution became sharper for the carbon produced using bamboo carbon with smaller potassium fractions and controlling the yield of activated carbon no less than 70%. It seems that potassium fractions in the middle lamella will accelerate the activation reaction, and then the micropore distribution tends to be broader when the activation reaction reaches the middle lamella.
