Filed: 1982-11-24
Abstract: PURPOSE:To save the energy for the removal of a light component such as methylacetylene from crude butadiene in a distillation column, by extracting a part of the vapor near the feed zone of the column, and recycling to the neighboring zone after condensation. CONSTITUTION:Crude butadiene containing a small amount of light component is supplied through the line 26 to the distillation column 31 and distilled. A part of the vapor is extracted from the line 32, condesed by the intermediate condenser 33, and returned to the column 31. The amount of vapor in the column above the returning zone is usually less than 1/5 of the amount below the returning zone. The vapor discharged from the top of the column is introduced through the line 27 to the condenser 28, and condensed. A part of the condensed vapor is recycled, and the remaining part thereof is discharged from the line 29. The condenser 28 is operated with a cold refrigernat, however, its load is remarkably lower than that of the intermediate condenser 33. A reboiler 35 is attached to the bottom of the column, and butadiene is discharged from the line 36.

IPC: G02B27/22
Filed: 1994-08-08
Abstract: PURPOSE:To miniaturize an entire device, to make a distance from a field lens to an observing position long, and to easily stereoscopically view the image of image information by superimposing and forming two pieces of image information as a spatial image on the field lens provided near an image-forming surface by a pair of image-forming lenses. CONSTITUTION:The spatial images of the image information 2L and 2R are superimposed on the image-forming surface by the image-forming lenses 5-L and 5-R of an image-forming means 5, and the corresponding spatial images are respectively observed by left and right eyes from the observing position by an observer through the filed lens 7 arranged on the image-forming surface, that is, a position where the exit pupils of the lenses 5-L and 5-R are formed into the image by the field lens 7. Thus, the observer observes the erect image of the image information 2L by positioning the left eye 12 at the image-forming position of the exit pupil of the lens 5-L. At such a time, the diameter, the focal distance and the image-forming position of each lens are set so that the image information 2-L for the left eye does not enter the right eye 13. Thus, the image information required for stereoscopic vision is properly guided to the left and the right eyes.

IPC: C09J11/06
Filed: 1984-10-01
Abstract: PURPOSE:An adhesive facilitating detection of leakage of water after bonding which is prepd. by incorporating a material which is discolored upon reaction with water. CONSTITUTION:For example, in a water feeding pipe line, water supply pipes 1a, 1a of rigid PVC are connected to each other by means of a coupling socket 1b. The pipes 1a, 1a coated with an adhesive 2 on the peripheral surface A of an end are inserted into the coupling socket 1b coated with the adhesive 2 on the inner surface B of the both ends, and connected with each other by setting the adhesive 2, wherein as said adhesive 2, a PVC resin-base adhesive mixed with about 2% material, such as fluorescein sodium, which is discolored upon reaction with water, is used. When the pipe line is filled with pressurized water, it is possible to easily detect visually a portion failing in adhesion because the adhesive 2 slightly forced out of the joint S is discolored from brown to green in the case of leakage of water.

IPC: G02B7/34
Filed: 1987-08-19
Abstract: PURPOSE:To eliminate the influence of stray light passing nearby the border surface of a condenser lens and to improve the accuracy of focus detection by beveling the border surface of adjacent condenser lenses not in parallel to the optical axis of a photographic lens.
