Title: Bar code reader pen
Inventor: SUGINO TADAAKI
IPC: G06K7/10
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To enable a bar code reader to read even when the center distance between a bar code and a bar code reader pen is extended by applying a monolayer coating reducing reflection to the irradiation plane of top end optical glass. SOLUTION: By applying the monolayer coating reducing reflection to the irradiation plane of the top end optical glass, even when the floating distance A between top end optical glass 3 and a bar code surface 4 is extended, the reflected light on the bar code surface 4 is reduced and the output level of a light receiving element is low, the output difference of white and black is intensified.  On the top end of a light emitting element 1, one end of a light guide 2 composed of an optical fiber for guiding light to the top end is abutted, the bar code surface 4 is irradiated with light from the other end of the light guide 2 for projection through a top end optical glass coat surface (monolayer reduction reflection coating part) 3-1, and one part of light reflected, namely, the reflected light of a reading diameter within a range limited by an iris diameter is made to pass through the top end optical glass 2, a lens 5 and a diaphragm 6 and read by the light receiving element 7 according to 1/a+1/b=1/f and magnification m=b/a.

Title: Purification of phosphoric acid produced through wet process
Inventor: MARUYAMA KENSAKU
IPC: C01B25/234
Filed: 1981-04-02
Abstract: PURPOSE: Phosphoric acid produced through the wet process is extracted with an alcohol and the extraction residue is extracted again with an extractant containing an alcohol and sulfuric acid of lower concentration than that in the first extraction to produce purified phosphoric acid of lowered sulfate group content in high extraction yield without any specific treatment.  
     CONSTITUTION: Phosphoric acid produced through the wet process is extracted with an alcohol to collect phosphoric acid. Further sulfuric acid and an alcohol are added to the extraction residue to effect extraction again for increasing the extraction yield wherein the concentration of the sulfuric acid is made lower than 80wt%. When the concentration of the sulfuric acid used here exceeds 80wt%, it becomes difficult to keep the content of sulfate group at 30ppm (as SO 4 ) or less, i.e., JIS specification for industrial phosphoric acid. That is presumed that sulfate esters are formed by the dilution heat of sulfuric acid, gets mixed into the extracts and their separation is difficult by usual washing.
