Abstract: PROBLEM TO BE SOLVED: To obtain a bright color image with simple constitution by combining a polarized light separating and synthesizing means with a color light separating and synthesizing means and efficiently utilizing illuminating light from a light source in a reflection type liquid crystal projection optical system. SOLUTION: A non-polarized white light beam outputted from a lamp 1 is separated to the transmitted light beam of a P polarized light beam and the reflected light beam of an S polarized light beam by a polarizing beam splitter 3. Thereafter, the P polarized light beam is made incident on a cross dichroic prism 4 and the S polarized light beam is made incident on a cross dichroic prism 5, then they are respectively separated to three primary color light beams. The respective separated color light beams are made incident on reflection type liquid crystal panels R1, G1, B1, R2, G2 and B2, optically modulated according to a specified image signal, and converted in terms of the P polarized light beam and the S polarized light beam and reflected and outputted.  The reflected and outputted linearly polarized light beams of R, G and B carrying image information of the respective color light beams are respectively made incident on the prisms 4 and 5, color-synthesized and returned to the splitter 3, whereby both polarized light beams are synthesized. Then, the synthesized light beam is enlarged and projected to a screen by a projection lens 6.

Abstract: PURPOSE: To attain image recording at a high speed with high quality by means of a shuttle type image recording means by delaying or quickening image recording by a recording head on a forward or a return path by a time corresponding to a deviation in a recorded image. CONSTITUTION: A printer section 102 uses a shuttle type head printer. A correction pattern having been stored in an image memory 104 in advance is printed on a recording medium by the printer section 102. A system control section 108 detects a deviation in the scanning line direction caused between a print image on a forward path and a print image on a return path by a recording head based on a correction pattern read by a scanner section 101. The time (correction time) corresponding to the deviation from the detected print image is set and the printing of the magnetic head on the forward path or the return path is delayed by the set correction time under the control for the printer section 101 afterward.

Abstract: PROBLEM TO BE SOLVED: To realize an effective and low cost method for extracting a metallic element with a solvent by removing an acid entrained from a preceding step and/or an acid produced by extraction through dialysis using an ion exchange membrane and thereby lowering the concentration of the acid in an aqueous phase. SOLUTION: An anionic exchange membrane is suited for an ion exchange membrane used in dialysis because an acid of a mixture of acid and salt is removed, and an extraction device to be used for extracting a metallic element with a solvent is routinely usable as an extraction device. An extracting medium which generates a hydrogen ion can be used as an extracting medium and for example, β-diketones such as acetylacetone, acidic organic phosphorus compounds such as di-2- ethlhexylphosphoric acid and fatty acids such as naphthenic acid are named. The extraction device and a dialysis device are installed in a room whose indoor temperature is controlled to the about 25±3 deg.C, and the internal temperature of the extraction device is not specially controlled, and further, a stirring operation is continued during the extraction of the metallic element.  Thus it is possible to significantly cut consumption of the alkali used for removing the acid without entailing the generation of by- product salts and enhance the extraction efficiency of the useful metallic element to produce is at a low cost.
