Title: Reflection type projecting screen
Inventor: IWAMURA SEISHIROU
IPC: G03B21/60
Filed: 1978-11-08
Abstract: PURPOSE: To obtain the bright images free from degradation in contrast even in a bright place by letting light be reflected effectively to a visible range and letting the harmful incident light coming from the portions other than the projector be absorbed into the screen.  
     CONSTITUTION: Convex lenses 12 such as the ones wherein the size is of the extent not identifiable in observation and the positions of the respective focuses 10 come to the outside of a reflecting surface 11 are formed over the entire surface of the incident face 9 of a transparent plate 8. Part of the reflecting surface 11 on the reflecting light axis is made mirror surface 13 and other portions are made black color surface 14. When parallel luminous fluxes enter such screen, they focus at the symmetrical points 16 of the focuses 10 and the luminous fluxes advancing from said points are diffused and radiated as reflected light as if they are luminous fluxes having radiation angle θ from light sources 17. In addition, harmful incident light is absorbed in the black color surface 14. Here, if the radiation angle θ is made equal to the observation range by selecting the thickness and refractive index of the transparent plate 8 and the focal length of the convex lenses 12, always bright images may be obtained.

Filed: 1981-09-02
Abstract: PURPOSE:To improve the corrosion resistance of chemical equipment by treating the surfaces of new metallic blank materials such as Ti, Zr, Ta or the like used in the chemical equipment with nitric acid. CONSTITUTION:In order to improve the corrosion resistance of chemical equipment which uses novel metals such as Ti, Zr, Ta or the like as a material, the surfaces of these novel metals are treated with nitric acid in the stage of blank materials or after the metals are assembled to the chemical devices. The concn. of the nitric acid to be used is preferably about >=2N. The treating temp. is above ordinary temp. and more particularly dipping the metals in boiling nitric acid is preferable. The preferable treatment time for dipping is about >=2hr. The corrosion resistance is improved more positively by heating the above-mentioned new metallic blank materials at about <=700 deg.C in an oxidative gaseous atmosphere such as air to form oxide films beforehand on their surfaces then subjecting the same to the above-mentioned nitric acid treatment. The combination with treatments with other acids such as sulfuric acid or a treatment with mixed acids is effective equally to the treatment with the nitric acid alone.
