摘要:
When an outer surface of an effective portion 20 of a panel 20 is substantially spherical, a diagonal axis of the effective portion, a long axial effective diameter, land a short axial effective diameter are Sd, Sh, and Sv, the panel is shaped to satisfy the relationship, Dp/Sd (Ta-Tmin) or .vertline.T max-Ta.vertline.>.vertline.T min-Ta.vertline..
