Title: Removing method for nitrogen oxides contained in exhaust gas
Inventor: KIYOMIYA MAKOTO
IPC: B01J23/74
Filed: 1978-01-13
Abstract: PURPOSE:To treat a large quantity of exhaust gas at comparatively low temp. with inexpensive catalyst which is hardly poisoned by SO2 etc. contained in the exhaust gas, by catalytic reaction of the exhaust gas contg. NOx with NH3 in the presence of laterite catalyst. CONSTITUTION:Laterite, or laterite having been pretreated with aq. soln. of inorg. acid and dried, is adjusted to a suitable moisture content, and is subjected to extrusion molding or rolling granulation in order to shape it into particles. The molded material is dried at 50-150 deg.C, calcined at 350-800 deg.C, pref, at 400-600 deg.C, to prepare catalyst. In the presence of the catalyst, the exhaust gas contg. NOx is then made to come into contact with NH3 to reduce NOx to N2. The temp. at which the catalytic reaction is effected is usually 200-500 deg.C, pref. 250-500 deg.C. The quantity of NH3 fed to the gas is pref. 0.8-2.0 mols per mol NO. The presence of O2 in the reaction system accelerates the reduction, and the simultaneous presence of water and SO2 to the extent 15% and 400 ppm respectively scarcely decreases the denitration ratio.

Title: Surface inspection apparatus
Inventor: TAKAHASHI IPPEI
IPC: G01N21/89
Filed: 1993-01-11
Abstract: PURPOSE:To detect even a defect of a pressing flaw of a to-be-inspected body well by setting the slit width of a photodetecting window which receives an inspecting light through the to-be-inspected body to be not larger than the diameter of the projected light beams. CONSTITUTION:Beams of a laser light 3 of predetermined 5mm diameter scan the surface of a continuously running film 8 in the widthwise direction. The light beams passing through the film 8 enter a photodetecting window 13 having the slit width of 1mm. If the light beams are cast to a flaw 8a, of the film 8, the light beams from the film 8 are divided up and down via the flaw 8a, not reaching the window 13. At this time, photomultiplier tubes 17, 18 at both ends of a receiver 10 output photoelectric converting signals S1, S2 proportional to the amount of light to an AGC circuit 20. The circuit 20, adding the signals S1 and S2, generates a signal S3. The signal S3 is converted to a signal S4 at 21, and further converted to an evaluating signal S5 at 22. An inspection width signal S7 from an inspection width setting circuit 25 are input along with the signal S5 to an AND circuit 23 which in turn outputs a defect detecting signal S8. A CPU displays 'a defect is present' when receiving the signal S8.
