The present invention provides a mercury removal system and method for effectively removing a mercury component, which is present in a gas stream in an extremely small amount in wet gas cleaning. The mercury removal system in wet gas cleaning includes a water washing tower for introducing therein a target gas containing a mercury component and transferring the mercury component into an absorbing solution, a flash drum (10) for flashing the absorbing solution discharged from the water washing tower to separate the absorbing solution into a gas component and waste water, an oxidation treatment means (1) for adding an oxidizing agent to the absorbing solution at the preceding stage of the flash drum, and a waste water treatment means for subjecting to coagulation sedimentation treatment the separated waste water containing the mercury component at the following stage of the flash drum to dispose of the mercury component as sludge.

The present invention provides a mercury removal system and method for effectively removing a mercury component, which is present in a gas stream in an extremely small amount in wet gas cleaning used for coal or heavy oil gasification, petroleum refining and the like. The mercury removal system in wet gas cleaning comprises a water washing tower for introducing therein a target gas containing a mercury component and transferring the mercury component into an absorbing solution, a flush drum (10) for flushing the absorbing solution discharged from the water washing tower to separate the absorbing solution into a gas component and waste water, an oxidation treatment means (1) for adding an oxidizing agent to the absorbing solution at the preceding stage of the flush drum, and a waste water treatment means for subjecting to coagulation sedimentation treatment the separated waste water containing the mercury component at the following stage of the flush drum to dispose of the mercury component as sludge. The present invention also provides a mercury removal method using the above-described system.

A convergence system for a cathode-ray tube having three detection magnetic pole pieces are disposed opposing to each other on both sides of a center beam for forming magnetic paths inside the neck part of a cathode-ray tube. A first convergence yoke is disposed outside the neck part of the cathode-ray tube for forming magnetic paths together with the magnetic pole pieces. A first coil is wound on a first convergence yoke to generate a magnetic field for correcting horizontal misconvergence between the center beam and a side beam on a side of the center beam. A second coil is wound on the first convergence yoke to generate a magnetic field for correcting horizontal misconvergence between the center beam and a side beam on the other side of the center beam. A third coil is wound on the first convergence yoke to generate a magnetic field for correcting vertical misconvergence between the center beam and both side beams. Furthermore, a second convergence yoke is disposed on the neck part of the cathode-ray tube at a different position from the first convergence yoke. A fourth coil is wound on the second convergence yoke to generate a magnetic field for correcting vertical misconvergence between both side beams.

A deflection system for a cathode-ray tube including a horizontal deflection core, a magnetic coil, and a vertical deflection coil toroidally wound on the magnetic core. The vertical deflection coil has a plurality of superimposed winding layers arranged with respect to a vertical axis of the deflection system with at least one of the layers of the vertical deflection coil being disposed asymmetrically with respect to the vertical axis or disposed symmetrically with respect to the vertical axis and having winding portions delimiting at least one gap along an extent thereof at a position other than the vertical axis. In this manner, an induced voltage in the at least one of the layers is substantially equal to an induced voltage in each of another of the layers at least in the region of the vertical axis, whereby ringing is substantially prevented.

A lithium-ion secondary battery capable of securing safety at a time of battery abnormality and restricting a drop in a high rate discharge property is provided. A lithium-ion secondary battery 1 has an electrode group 5 formed by winding a positive electrode plate 2 in which a positive electrode mixture including a positive electrode active material is formed at a collector and a negative electrode plate 3 in which a negative electrode mixture including a negative electrode active material is formed at a collector via a porous separator 4. A flame retardant is mixed to the positive electrode mixture of the positive electrode plate 2. The mode of pore diameters formed at the positive electrode mixture, which is measured by a mercury porosimetry, is set to a range of from 0.5 to 2.0 μm. The moving path for lithium-ions and at the same time the moving path for electrons are secured at a charge/discharge time.

Provided is a catalyst which can prevent a lowering in selectivity for a target product in a gas phase catalytic reaction and has an excellent frictional resistance. A catalyst which is a supported catalyst comprising an inert support that is coated with a catalyst powder, characterized in that the inert support is ring-shaped and has an outer periphery that is curved in the lengthwise direction of the support, and the catalyst is produced by granulation in a moisten environment. The above described catalyst is useful in the gas phase oxidation of propylene, isobutylene, tertiary-butyl alcohol or methyl tertiary-butyl ether to thereby produce an unsaturated aldehyde corresponding thereto, or in the gas phase oxidation of such an unsaturated aldehyde as described above to thereby produce an unsaturated carboxylic acid.
