Title: Coating method of inorganic substrate
Inventor: MITSUOKA YOSHIAKI
IPC: B05D7/00
Filed: 1978-08-31
Abstract: PURPOSE: To form three-dimensional patterns readily and inexpensively by simultaneously spraying the coatings using solvents of different boiling points from two or more spray guns containing said coating onto an inorganic substrate.  
     CONSTITUTION: The coatings using two or more kinds of solvents of different boiling points are simultaneously sprayed onto the surface of an inorganic substrate 1 composed primarily of cement, plaster, etc., by using separate spray guns and the plural coatings sprayed are mixed on the coated surface of the substrate 1. Then, because of a difference in the boiling points of the solvents in the coatings, the solvent of the lower boiling point evaporates first in the coated surface and the resin in the coatings deposit. Next, the solvent of the high boiling point evaporates with a delay. Hence, the three-dimensional and varied uneven patterns 2 composed of the even films may be readily and inexpensively formed in the coated surface.

Abstract: PURPOSE:To convert the polarizing state of a beam regardless of the wavelength of light by utilizing a phase change between a P wave and an S wave to be generated by reflecting the beam by using an optical means having a reflection face. CONSTITUTION:All the linearly polarized beams having various wave-lengths of semiconductor lasers 1-4 are converted to circularly polarized beams by a Fresnel prism 100 wile receiving the operation of reducing position error between P wave and the S wave to pi/2.
