Abstract: A purifying unit containing an adsorbent is positioned between the discharge outlet of a discharge pipe from which boiled water is discharged, and an extracting chamber, so that boiled water flows into the extracting chamber after detrimental components are removed from the boiled water by the purifying unit. Further, a passage change-over section is provided in order to circulate water through the heater until the water is heated up to a temperature suitable for extraction of coffee, and the passage change-over section allows water to be discharged into the extracting chamber from the discharge outlet of the discharge pipe when the water is heated up to the suitable temperature.

Abstract: A cursor moving system includes a designated-area management unit for processing for display on a screen of areas to be designated by a cursor. A cursor position management unit processes movement of a cursor indication position on the screen according to a cursor moving operation by a pointing device. A cursor position determination unit searches for a designated area to which the cursor belongs now, and another designated area existing in a travelling direction of the cursor, based on information on a current position of the cursor and information on a travelling direction of the cursor received from the cursor position management unit in response to the pointing device. It also determines whether or not the nearest designated area existing in a travelling direction is separated from the current designated area.
