Abstract: PURPOSE: To prevent a partial increase in film thickness or liquid dripping in a spin color developing method. CONSTITUTION: A soln. is emitted to a color developing table 11 held at a falling position from a soln. supply part 12. After the soln. supply part 12 is moved to a retreat position, the color developing table 11 is raised to be rotated.

Abstract: PURPOSE:To heighten fire resistance efficiency in a high temperature region by forming a fire resistive material for structure of a building of a fire resistive layer with an inorganic refractory fiber material as its main material, a fire resistive layer with an incombustible material containing moisture as its main material and a plywood for structure. CONSTITUTION:A fire resistive material 35 for structure is constituted of a plywood 34 for structure, a first five resistive layer 36 and a second fire resistive layer 37. When the refractory layer 37 with an incombustible material containing moisture as its main material bears a fire protection function in a comparatively low temperature region, and when it encounters temperature in a low temperature region, moisture is discharged from the incombustible material and consequently, temperature on its back face is lowered. In the meantime, the refractory layer 36 with an inorganic refractory fiber material as its main material bears the fire protection function in a high temperature region, and it certainly holds heat, flame and others which cannot be prevented by the fire resistive layer 37. The plywood 34 for a wall face 5 is fixed with nails on an outdoor S1 side of a column 3, the five resistive layers 36, 37 are arranged on the outdoor S1 side of the plywood 34, and thin coating mastic polishing finish 62 is applied on the extreme outer face of the fire resistive layer 37. Consequently, it is possible to heighten refractoriness in the high temperature region.
