    摘要: Silica-calcium carbonate composition particles having the characteristics of both synthetic silica and calcium carbonate are described along with paper having the particles internally filled therein and a method for making the particles.In the carbonation reaction, which typically involves a step of forming calcium carbonate, while agitating a calcium hydroxide slurry, a mixed gas of carbon dioxide and air is introduced thereinto and synthetic silica, such as colloidal silica or the like, is added before the carbonation rate arrives at 95% but after commencement of the carbonation reaction, followed by further introduction of the mixed gas to continue the carbonation reaction and completion of the carbonation reaction at the time when the pH of the slurry reaches 7, thereby providing the composite particles.

    摘要: A medium dispensing apparatus, a stirring and heat-retaining apparatus, and a dispensing method are provided which enable a medium to be surely supplied at an adequate temperature while variation of the dispensation amount of the medium, liquid dripping which produces air bubbles, and pulsated ejection are prevented from occurring, and local gelation of the medium and contamination due to various kinds of bacteria are prevented from occurring. In a midway of a medium sending tube 11 serving as a medium passage which guides a medium 2 from a medium container 3 to a nozzle 7, a medium returning passage 14 through which the medium is returned to the medium container 3 is branched. When the medium is not to be dispensed, the medium is circulated while the temperature of the medium is retained, and the temperature of the whole of the medium passage from the branching position of the medium sending tube 11 with respect to the medium returning tube 14 to the nozzle 7 is retained by auxiliary heating means 16. When the medium is to be dispensed, an adequate amount of the medium is supplied by means of throttle portions 50 and 51 which are disposed in two or more positions of the tube 11 and the diameter of which is smaller than that of another portion of the tube 11. The temperature of the medium is retained while uniformly stirring the medium by a first stirrer 5a in the medium container 3 and a second stirrer 5b in a heating bath 6.
