Boron-substituted graphite, which contains N-bonded boron atoms in a small proportion relative to whole substituted boron atoms, is produced by heating a feed fine particulate mixture of an infusibilized carbonaceous material and a boron compound such that the carbonaceous material is carbonized into a carbon structure, raising a temperature of the resulting heated fine particulate mixture promptly to a graphitization treatment temperature in an inert atmosphere unreactive with boron, retaining the graphitization treatment temperature for a time sufficient to allow graphitization of the carbon structure to proceed to a desired extent, and then quickly cooling the resulting graphitized mixture. The boron-substituted graphite is useful as a negative electrode in a lithium-ion secondary battery.

A method for decreasing the concentration of a chlorinated aromatic compound in the exhaust gas from a combustion furnace. The exhaust gas from the combustion furnace is passed through a bag filter. The concentration of the chlorinated aromatic compound in the exhaust gas is measured and the operating temperature of the bag filter is adjusted based on the measured concentration of the chlorinated aromatic compound in order to decrease the concentration of the chlorinated aromatic compound in the exhaust gas.

Incineration apparatus and method which suppress generation of dioxins

An incineration apparatus which can suppress the generation of dioxins, including a combustion furnace (,) for burning a combustible in combustion air within the furnace, chlorinated aromatic compound measuring device (,) for measuring an amount of a chlorinated aromatic compound generated in the combustion furnace, and control device (,) for monitoring the amount of the chlorinated aromatic compound generated, obtained by the measuring device (,), and varying operating conditions of the combustion furnace (,) on the basis of the monitored result, such as to decrease the amount of the chlorinated aromatic compound generated in the combustion furnace (,).

A laminated steel sheet for cans comprises: a steel sheet; a metallic chromium plated layer with a 5 to 150 mg/m.sup.2 coating weight formed on the sheet; a hydrated chromium oxide layer with a 3 to 15 mg/m.sup.2 coating weight in terms of chromium formed on the metallic chromium layer; a bonding layer formed on the hydrated chromium oxide layer; and a biaxially oriented polyethylene terephthalate resin film formed on the bonding layer with a strip-shaped margin left for welding, the bonding layer being obtained by curing an adhesive having bisphenol A epoxy resin which has 15,000 to 30,000 number average molecular weight and is from 70 to 90 wt. % of said bonding layer with the remainder being resol phenol resin which has a base of bisphenol A. Other related laminated sheets are also provided.

Laminated steel sheet for cans

A laminated steel sheet for a welded can which includes: a steel sheet; a plating layer formed on the steel sheet, the plating layer having a surface roughness represented by a PPI of 5 to 150, the plating layer having a tinning layer and a chemical treatment layer, the tinning layer being formed on the steel sheet and the chemical treatment layer being formed on the tinning layer, the tinning layer having a coating weight of 0.9 to 2.8 g/m.sup.2, the chemical treatment layer containing 5 to 50 mg/m.sup.2 of metallic chromium and hydrated chromium oxide containing 5 to 25 mg/m.sup.2 of chromium; and a resin film thermo-compressed on the plating layer in a band form, the resin film being a biaxially oriented film of a polyethylene terephthalate copolymer, the polyethylene terephthalate copolymer having an acid component of which 0.5 to 10 mol % is isophthalic acid.
