摘要： A flame-retarded speaker diaphragm is prepared by making a cone from cellulose fibers, impregnating the cellulosic cone with a solution of a trimethylol melamine monomer, an organic phosphorus- and nitrogen-containing compound, and a trialkyl amine catalyst in an alcohol solvent, and heating the impregnated cone until the solvent is removed and the melamine resin is cured. Flame retardancy is imparted to the cellulose cone-shaped diaphragm without the sacrifice of its frequency response.

摘要： Feature points (41, 42, 43) in the heat image (10) of a casting die (1) are extracted and a predetermined geometrical conversion processing is performed on the heat image (10) such that the feature points are superimposed on the reference feature points (61, 62, 63) set in a reference heat image (30) picked up previously to generate a corrected heat image (20). A difference image (40) is generated by superimposing the corrected heat image (20) and the reference heat image (30) such that the corrected feature points (51, 52, 53) in the corrected heat image (20) is superimposed on the corresponding reference feature points (61, 62, 63). With such an arrangement, a highly reliable difference image can be generated even when the imaging field of vision slips off among a plurality of heat images.

摘要： Disclosed herein is a technique of removing metal contained in a solution through chelation, which makes it possible to preclude undesired aggregation and permit effective aggregation through an aggregating process. A surface active agent containing a hydrophobic group, a hydrophilic group and a chelating group is added to the solution to be processed, and subsequently an aggregating process is carried out. The chelating group chelates metal, the hydrophilic group prevents undesired aggregation, and the hydrophobic group is effectively aggregated in the aggregating process. Various uses are possible by selecting the charge of ligand.

摘要： Provided is a method for producing a heat sink that can easily and effectively form a heat radiating film on the surface of a substrate without requiring enormous heat energy for increasing the temperature of the substrate. The method is a method for producing a heat sink having a substrate and a heat radiating film formed on the surface of the substrate, including a first step of casting a substrate by injecting molten metal into a cavity of molding dies; and a second step of applying a heat radiating coating to the substrate through spraying or dropping in the period from when the molding dies are opened after the casting until when the temperature of the substrate that has been cast becomes lower than the deposition temperature that is a temperature necessary to deposit the heat radiating coating on the substrate.

摘要： A method of separating an aqueous colloidal solution by agglomeration into water and agglomerate of colloidal particles by applying voltage to the aqueous colloidal solution to promote the agglomeration of colloidal particles. The frequency of the voltage to be applied to the aqueous colloidal solution is increased to about 10 kHz to improve efficiency of agglomeration and suppress electrolysis of water. As the frequency is increased, hydrogen is generated earlier than the reaction of oxygen generated by the electrolysis of water with the colloidal particles, thus not oxidizing the colloidal particles. Further, as the frequency is increased, the colloidal particles tend to obtain a greater oscillation energy, thus facilitating the agglomeration thereof.
