摘要:
A method for removing nitrogen oxides and organic chlorine compounds from a combustion waste gas, which comprises the steps of: adding ammonia (NH.sub.3) as a reducing agent to a combustion waste gas containing nitrogen oxides and organic chlorine compounds; causing the combustion waste gas added with ammonia to contact with, while keeping the temperature of the combustion waste gas within a prescribed range, with a catalyst comprising at least one selected from the group consisting of platinum (Pt), palladium (Pd), ruthenium (Ru), manganese (Mn), copper (Cu), chromium (Cr) and iron (Fe) and oxides thereof, supported on the surface of a carrier comprising at least one selected from the group consisting of titanium oxide (TiO.sub.2), silicon oxide (SiO.sub.2), aluminum oxide (Al.sub.2 O.sub.3) and zirconium oxide (ZrO.sub.2), thereby removing nitrogen oxides and organic chlorine compounds from the combustion waste gas.

The present invention discloses a method of controlling combustion of a fluidized-bed incinerator. In a fluidized-bed incinerator (5), a method of controlling combustion of the fluidized-bed incinerator comprises measuring a supply rate of incineration waste by a supply rate measuring unit (11) using a photoelectric element (1) arranged on a shoot (2) for supplying incineration waste (3) from a dust feeder (4) to the incinerator (5), and when the supply rate of incineration waste is higher than a predetermined value, decreasing a supply rate of incineration waste of the dust feeder 4 to suppress a combusting operation, increasing an induced gas rate of an exhaust gas induced blower (9) of the incinerator to suppress an increase in an incinerator internal pressure decreasing a flow rate of fluidizing air of a forcing blower (7) to suppress a combusting operation, or increasing a flow rate of a blower (8) for supplying air to a free board portion to prevent production of an unburnt gas.

A method for efficiently amplifying abnormal prion protein (PrPSc) derived from bovine spongiform encephalopathy (BSE) is provided. Ultimately, the invention aims at eradicating the transmission of a prion disease by detecting a BSE-infected cow early and developing a method for inactivating prions and permitting early examination of prion inactivation. Provided is a method for efficiently amplifying PrPSc derived from BSE, wherein the method is based on a PMCA (protein misfolding cyclic amplification) method in which normal prion protein (PrPC) is used as a source and PrPSc is used as a seed, and PrPSc derived from BSE is amplified by stir-mixing, incubating, and sonicating both the PrPC and the PrPSc repeatedly, and wherein the method includes performing stir-mixing-incubation-sonication in the presence of a polysaccharide sulfate.

A luminescent product molded by centrifugal molding which is inhibited from curling and has a white layer for improving phosphorescent performance. The product comprises: a hiding layer formed from a first mixture which is a mixture of a first thermosetting resin and a pigment by subjecting the mixture to centrifugal molding with heating; a phosphorescent layer obtained from a second mixture which is a mixture of a second thermosetting resin and a phosphorescent pigment having a higher specific gravity than the second thermosetting resin by pouring the second mixture on the hiding layer and subjecting it to centrifugal molding with heating; and a transparent layer. The phosphorescent layer is located nearly at the center of the product thickness. Thus, the product can be effectively inhibited from curling.

A storage battery includes: a bottomed metal case (10) accommodating an electrolyte and a collector (7) having a flat plate connected to one side of an electrode assembly (5) containing a strip-shaped positive electrode plate (1), a strip-shaped negative electrode plate (2), and a separator (6); a sealing plate (11) sealing upside of the bottomed metal case; and a lead terminal (9) electrically connecting the sealing plate to the collector, wherein the collector has at least one projection (13) and the collector and the lead terminal are electrically connected with each other via the projection. This construction eliminates the problem of increased contact resistance between the lead terminal and the collector and realizes a storage battery having high current discharging performance in which the contact resistance is reduced.
