Title: Optical prism
Inventor: OKAMOTO NORIHISA
IPC: G02B5/04
Filed: 1988-12-27
Abstract: PURPOSE:To obtain the optical prism which has no double refractiveness by using plastic formed by mixing or combining org. materials which are positive and negative in optical anisotropy. CONSTITUTION:This prism consists of the plastic formed by mixing or combining the org. materials which are positive and negative in the optical anisotropy. Namely, the optical anisotropy of the molecules appears as a difference in the correlation of the direction 102 of the molecule skeleton of a high polymer 101 and the light 104 oscillating in the direction 103 perpendicular thereto; more specifically, the optical anisotropy appears as the difference as to whether the substituent, such as halogen element or benzene ring, having the easily distortable electron cloud exists in the molecule skeleton direction or in the direction perpendicular to the skeleton. This anisotropy includes the anisotropies which are positive and negative in code and the double refractiveness is suppressed by blending the suitable amt. thereof or combining the same in the form of copolymn.

Therefore, solids are not made to adhere on a deck plate or the like to increase the pressure loss as heretofore generated, nor the solid reducing work is required. The absorption reaction liquid is stored in the jet bubbling pipe by utilizing the pressure balance of the flue gas, and the flue gas is introduced at significantly high speed from a lower opening to form a superjet bubbling layer in the pipe. The gas-liquid contact efficiency is improved by the arrangement.  The absorption reaction liquid is separated from purified flue gas on the upper end of the pipe in the gas-liquid separation chamber.
