Title: Method for removing se from se-containing liquid
Inventor: KIJIMA SHUN
IPC: C02F1/66
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To sufficiently remove Se, especially Se (VI), in a concd. aq. salt soln. by injecting a reducing agent into an Se-contg. liq. discharged from an Se-contg. glass producing factory, keeping the pH of the liq. successively at a specified value and finally separating the reduced Se from the liq. SOLUTION: When this method is applied to a plant for treating the liq. absorbent of a stack gas desulfurization tower, an aq. soln. of a reducing agent such as ferrous sulfate set at about 80 deg.C is introduced into a first reaction tank at pH 7-13. Since the first reaction tank is kept alkaline, the ferrous ion added as the reducing agent is reduced to iron hydroxide and deposited in the soln. Besides, air, for example, is blown and an oxidizing agent is injected into the stack gas as the pretreatment for the first reaction tank to oxidize the SO3 <2-> in the soln. to SO4 <2-> to the utmost. Subsequently, the concn. of Se remaining in a concd. aq. salt soln. is lowered in the second stage with pH lower than that of the first stage by pH >=2, and the remaining Se is separated and removed outside the system by the succeeding removing stage.

Title: Bill collecting mechanism
Inventor: NONAKA HISAMITSU
IPC: G07D9/00
Filed: 1986-05-22
Abstract: PURPOSE:To securely collect even an abnormally conveyed, skewing bill and miniaturize a device by providing a sweeper roller which pushes said bill in an erect state which is pushed out by means of a ring type belt, against a bill collecting part by the rotation of its plural vane bodies. CONSTITUTION:A bill 5 which is conveyed from the upper part is discharged toward a bill guide 3 by means of feed rollers 1a, 1b and hits against ring type belts 4a, 4b. After that, since the discharged bill 5 deforms the belts 4a, 4b while advancing along their surfaces, the speed at the time of discharge is reduced, relieving an impact force at the time of dashing against a guide rail 6. Thereby, the rebound of the bill 6 due to collision with the rail 6 can be restrained. Then, the deformation of the belts 4a, 4b ends when the bill 5 arrives at the rail 6, the bill 5 is pushed in the direction of a bill collecting board 7 in an erect state due to the restoring force of the belts 4a, 4b and, when coming to a position where the vanes 2a of a sweeper roller reach, the bill 5 is pushed against the bill collecting board 7 by means of the vanes 2a, thereby, collecting even a skewing bill in an erect state due to the actions of the belts 4a, 4b and the roller 2.

Title: Exhaust gas cleaner
Inventor: TANIGUCHI HIROYUKI
IPC: F01N3/02
Filed: 1993-05-20
Abstract: PURPOSE:To provide an exhaust gas cleaner, with which the damage in a filter can be surely detected by a simple structure. CONSTITUTION:The amount G of particulates collected by a filter is estimated (100) based on the engine speed, the temperature and the pressure of exhaust gas. When the estimated amount G of the collection reaches a prescribed level, it is judged that a filter reactivation time is due (108), and the filter is reactivated (114, 116). The cumulative rotation speed after the previous completion of reactivation is integrated (101). When the collected amount G reaches a prescribed level before the cumulative rotation speed reaches a prescribed minimum value, and when the collected amount G does not reach a prescribed level even after the cumulative rotation speed reaches a prescribed maximum value (104), it is judged that the filter is defective. Otherwise, it is judged that the filter is defective when the exhaust pressure falls out of a prescribed range.

Filed: 1986-05-23
Abstract: PURPOSE:To extend the service life of a thermally ceramic sprayed layer to the exfoliation thereof by melting and resolidifying the surface of the ceramic sprayed layer formed on a base material by using high-density energy and growing the generated fine cracks by a cold-heat cycle. CONSTITUTION:The thermally ceramic sprayed layer 3 is formed via a bond layer 2 on the surface of the base metallic material 1. The high-density energy 5 such as laser or plasma is irradiated to the surface of such sprayed layer 3. The irradiation position is moved to quickly melt the extreme surface layer 3A and thereafter, said layer is quickly solidified to form a resolidified layer 3B and to generate the many fine cracks 6. The pores 4 of the surface layer 3A are mostly annihilated in this stage. The entire part of the sprayed layer 3 is then subjected repeatedly to the cycle of heating and cooling to propagate and grow the cracks 6 to the layer 3C which is not subjected to the resolidification treatment. The fine cracks 6 having directivity function effectively to relieve the thermal stress during use. The service life of the ceramic coated member is thus extended.

Abstract: PURPOSE:To facilitate the measurement and to prevent the production of measuring errors, by providing an optical sensor in a device for testing abrasion resistance of a film, and judging the time when the substrate of a test piece begins to appear to be observed by an electric circuit instead of visual observation. CONSTITUTION:A test piece 2 is fixed to a turntable 1, and an abrasion wheel 3 is set thereon. A switch 6 is closed and the turntable 1 is rotated. At the same time, a counter 5 is started. When the painted surface of the test piece 2 is abraded by the abrasion wheel 3, the painted film is gradually peeled off, and a part where the substrate can be seen, appears. At this time, an optical sensor 7 detects the part. A comparator circuit 9 compares the output voltage from the optical sensor 7 with a reference voltage. When a difference is generated between both voltages, an output is generated from the comparator circuit 9. Then, an energized relay winding 15 actuates the switch 6 and a power source is cut off. The number of rotation of the turntable indicated by the couner 5 becomes the data for the abrasion resistance. Thus the measurement is facilitated and the measuring errors can be eliminated.
