Title: Fusing treatment of incineration ash
Inventor: TANI TOSHIO
IPC: B09B3/00
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To provide a fusing treatment method of incineration ash capable of obtaining fused slag low in the elution of heavy metals such as Pb in the case of forming fused slag by heating for fusion and cooling the incineration ash of the municipal refuse or the like even in the fusion by heating at a lower temp. SOLUTION: Fe powder or the like is mixed with the incineration ash and fused by heating. The Fe powder acts as a deoxidizer, and then, the heavy metal oxides such as PbO are reduced to react with chlorine in the incineration ash to form the chlorides even in the lower fusing temp. Since the chlorides are low in b.p. and m.p. and easily volatilized, the transferring ratios of Pb or the like to the fused slag are reduced and quantities of the eluted substances from the slag are lowered. Since the fusing temps. are lowered in this way, the service life of the device is improved, the energy cost is reduced and the over all fusing cost is made low.

Title: Corrosion-resistance enhancing method for hard-chrome plated film
Inventor: NITOU TAKEHIRO
IPC: C25D5/48
Filed: 1990-10-08
Abstract: PURPOSE:To form polishing layer to seal the cracks by subjecting the surface crack grooves of a plating film to ultra-finish polishing. CONSTITUTION:The polishing amount for ultra-finish working is varied depending upon the groove width state of each crack opening in a plated film 5 and the crack density thereof to form a polishing layer 3 on the surface of the plated film 5, thereby sealing the crack openings. Namely, the ultra-finish polishing which is based on the (f) value defined in accordance with the crack density is performed. As a result, the plated film 5 ceases to have any permeation crack via which corrosion substances permeate the surface of a base member. This enables special increase in the corrosion resistance of the iron base member covered with the hard chrome plated film 5.
