After generated hydrogen is dried by a moisture adsorbing device 3, it is purified to hydrogen of >=99% by a separating and purifying device 1, which is constituted of a high-purity hydrogen separating membrane. Thereafter, this hydrogen is stored in a storage device 5. On the other hand, after ash is sufficiently retained in a device 2, it is led to a dehydrating dryer 6 and dried via mechanical dehydrating operation of filtration and compression. Further, filtrate is returned to the device 2 in accordance with necessity. Residue contg. moisture of several percentage is changed into vitriform slag by a melting furnace 7. This vitriform slag is cooled and solidified to form a lump shape and made harmless. As a result, hydrogen is obtained from incineration ash by a simple method and also the residue is easily melted and solidified. Heavy metal is changed into hydroxide and volatilization thereof is prevented.

Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a concrete retaining wall suitable for rearing fireflies by fitting slag containing calcium oxide to piled blocks positioned below the water surface, and forming void space opened to the front faces of the blocks, inside the piled blocks positioned above the water surface. SOLUTION: The front face opening of piled blocks 1 and void space filled with sediment are positioned above the water surface. Grass and the like therefore grow, and fireflies can lay eggs on the grass. Slag 5 fitted to the front faces of the piled blocks 1 is positioned below the water surface. The slag 5 contains calcium oxide forming the shell of Semisulcospina to be the feed of larvae of fireflies, silicic acid to be the feed of Semisulcospina and magnesium oxide for expediting the growth of diatom. Semisulcospina therefore increases, and the larvae of the fireflies eat Semisulcospina to glow and breed. Optimum environment for the egg laying of fireflies and the growth of larvae is therefore created to be suitable for rearing fireflies.

Title: Ink drop creating/flying apparatus
Inventor: SATO HIROAKI
IPC: B41J2/085
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To fly an ink drop stably by creating an ink drop from ink generating a capillary wave in response to a specified signal and controlling an electric field generating means to generate an electric field for flying the ink drop. SOLUTION: An electric field generated by applying a voltage between first and second electrodes causes charge shift at the wave head 24 of a capillary wave 22 generated in an ink 3. The wave head 24 is cut under that state to create an ink drop 6 which flies toward the first electrode to arrive at (print) a record medium. Since an ink 3 forming a capillary wave on the surface at the forward end of an oscillatory member 1 is cut, through action of the electric field, to produce an ink drop being flied, high speed stable flight of ink drop is realized. In order to enhance the effect of stable flight, the second electrode is preferably brought as close as possible to oscillatory member. More specifically, it is set in the range of 100 μm-5 mm.
