Title: Purifying method for recovered hydrochloric acid
Inventor: MORIMOTO YASUO
IPC: C01B7/07
Filed: 1981-02-16
Abstract: PURPOSE: To efficiently purify recovered hydrochloric acid by bringing the acid into contact with air in a tower composed of a reflux cooler and a stripper and treating it with a neutral phosphate soln. to remove the malodorous and colored components.  
     CONSTITUTION: Recovered hydrochloric acid before purification is introduced into the reflux cooler 1 of a tower from the top 3. In the cooler 1 the acid is heat exchanged for rising hot air, mass transfer is caused to release part of the malodorous component, and CHl and steam are condensed and dropped into the stripper 2. In the stripper 2 the malodorous component is removed almost thoroughly with steam or the like introduced from the intermediate part 7 of the tower and air or the like introduced from the lower part 5 of the tower while refluxing the hydrochloric acid with a pump 4. The acid is then introduced  into a solvent extractor 8 through a branch pipe 6 and brought into contact with a neutral phosphate soln. to remove the colored component. The purified hydrochloric acid is recovered in a vessel 10. The solvent contg. the extracted colored component is regenerated by back-extracting the component with a releasing device 9, and the regenerated solvent is refluxed to the extractor 8 through a solvent vessel 11.

Title: Video projector
Inventor: ONOZUKA KUNIHARU
IPC: G02F1/13
Filed: 1993-02-10
Abstract: PURPOSE:To prevent trapezoid distortion occurring when a video is projected from the obliquely upper part of a screen. CONSTITUTION:Parallel beams radiated from a light source 11 are reflected in the direction of about 90 deg. by a first reflection mirror 15, and irradiate a liquid crystal panel 12 side. The beams reflected at the mirror 15 irradiate the respective picture elements 13 of the panel 12 through a light guiding lens 16. Thus, the video formed on the panel 12 is projected on a second reflection mirror 18 through a projection lens 17. The surface of the mirror 18 is concave on a lower end part, and is gradually flat toward an upper end part. Therefore, the lower side of the video projected from the lens 17 is reduced by the concave surface of the mirror 18 and is reflected. When the video is projected through a projecting lens 14, and is projected on a screen 2 inclined with respect to the optical axis of the lens 14; the trapezoid distortion is corrected, and the video is displayed as a normal video.

Title: Electrostatic attraction type dust cleaner
Inventor: MATSUMOTO TAKESHI
IPC: A47L7/00
Filed: 1989-01-31
Abstract: PURPOSE:To improve the dust attraction ability by providing a rotary drum with its peripheral surface charged, arranging rotary brushes at the front side and the rear side in the advancing direction, and providing a control mechanism to prevent the rotary brushes from rotating in the reverse direction to the dust gathering direction. CONSTITUTION:By pushing a cleaner main body 21 forward (in the direction (d)), a rotary brush 30 rotates in the direction (a) and gathers dust in a rotary drum 28. In this case, since a rotation force reverse to the direction (b) acts to a rotary brush 31, a control mechanism 51 operates to stop the rotary brush 31. When the cleaner main body 21 is pushed rearward, (in the direction (e)), the rotary brush 31 rotates in the direction (b), and gathers dust in the rotary drum 28. In this case, since a rotation force reverse to the direction (a) acts to the rotary brush 30, the control mechanism 51 operates to stop the rotary brush 30. By moving the cleaner main body 21 forward and rearward, the dust is gathered into the rotary drum 28 and absorbed to the rotary drum 28. And when the rotary brushes 30 and 31 pass on the dust attached to the surface to clean, the dust is adsorbed both in the directions (a) and (b), and the dust and dirt clung fast to the surface to clean can be well removed.
