摘要:
The disinfection method of the present invention includes steps (i) and (ii). In step (i), a voltage is applied, in an aqueous liquid (21), between a counter electrode (13) and a first ion-adsorbing electrode (11) containing a first electrically conductive material (11a) capable of adsorbing an ion reversibly, thereby changing a pH of the aqueous liquid (21) to a value less than 5 or to a value greater than 9. In step (ii), the pH of the aqueous liquid 21 is adjusted to a range of 5 to 9.
摘要:
In the method of the present invention, in an aqueous solution 20 containing at least one type of ions (L) other than hydrogen ions and hydroxide ions, voltage is applied between an ion-adsorbing electrode 11 containing an electrically conductive material (C1) capable of adsorbing ions and an ion-adsorbing electrode 12 containing an electrically conductive material (C2) capable of adsorbing ions so that the ion-adsorbing electrode 11 serves as an anode. Thus the electrically conductive material (C1) is allowed to adsorb an anion contained in the aqueous solution 20 and the electrically conductive material (C2) is allowed to adsorb a cation contained in the aqueous solution 20. Subsequently, in a liquid 30 containing water, voltage is applied between either the ion-adsorbing electrode 11 or the ion-adsorbing electrode 12 and counter electrode 13 or 14, resulting in changing the pH of the liquid 30.

In the process of the present invention, first, voltage is applied between an electroconductive substance (11) capable of adsorbing ions and a counter electrode (12) in an aqueous solution (20) containing at least one type of ions (L) other than hydrogen ions and hydroxide ions, so that at least a part of the ions (L) contained in the aqueous solution (20) are allowed to be adsorbed on the electroconductive substance (11). Subsequently, the electroconductive substance (11) is removed from the aqueous solution (20) and then is washed.
摘要:
In a container 10, a first electrode 11 containing a first electrically conductive material capable of adsorbing an ion and a second electrode 12 containing a second electrically conductive material capable of adsorbing an ion are immersed in a liquid (aqueous solution 13) containing at least one type of ion other than hydrogen ion and hydroxide ion. Then a voltage is applied between the first electrode 11 and the second electrode 12 so that the first electrode 11 serves as an anode. This voltage application allows the first electrode 11 and the second electrode 12 to adsorb anions and cations contained in the aqueous solution 13, respectively. In this ion adsorption step, the aqueous solution 13 is treated by a batch method. The voltage to be applied is higher than a voltage that causes electrolysis of a solvent of the solution, assuming that no voltage drop is caused by the liquid (aqueous solution 13).

The portable device of the present invention for regulating the hardness of drinking water includes a collapsible electrode group (20) including ion-adsorbing electrodes (21) and (22) and a power supply (13) for applying a voltage between the ion-adsorbing electrode (21) and the ion-adsorbing electrode (22). The first ion-adsorbing electrode (21) includes a first electrically conductive material capable of adsorbing ions. The second ion-adsorbing electrode includes a second electrically conductive material capable of adsorbing ions. In an example, a voltage is applied between the first ion-adsorbing electrode (21) and the second ion-adsorbing electrode (22), with the first and second ion-adsorbing electrodes (21) and (22) being immersed in the drinking water (25). The applied voltage regulates the amount of ions adsorbed on the first and second electrically conductive materials, and thereby the hardness of the drinking water is regulated.

摘要:
A method for testing a precursor of a secondary cell with high reliability and high efficiency to judge the precursor to be acceptable or defective. The current flowing when a test voltage is applied between a pair of electrodes is measured before an electrolyte is placed between the electrodes. If a current the current value of which exceeds a predetermined reference current value (13) is detected during the time from the start of application of a voltage to a normal secondary cell precursor until the current becomes constant, the precursor is determined to be defective.

A piezoelectric actuator 21 has: a piezoelectric actuator part 22 made up of a common electrode 27, a piezoelectric element 29, and an individual electrode 33; an electrical interconnection joint part 43 formed on the individual electrode 33; an electrical interconnection 45 formed on the electrical interconnection joint part 43; a head block 47 fixed to a nozzle plate 39 through the electrical interconnection 45; and a PI tape 49 disposed within the head block 47. A closed space 57 is defined between the head block 47 and the nozzle plate 39. The closed space 57 is divided by the PI tape 49 into two sections. Of these two sections of the closed space 57, the one on the side of the head block 47 constitutes a first closed space 57a. A moisture absorbent 52 is sealed within the first closed space 57a. Relative humidity within the closed space 57 of the ink jet head 1 is not less than 0% nor more than 20%.
摘要:
A ceramic electronic component includes two or more electrodes 5 and 6 spaced at a predetermined distance from each other, between which a potential difference is produced in operation and a void 9 that penetrates to the outside is provided. In the void 9, a water repellent film 10 is formed. This prevents water vapor from being absorbed in the void 9 connecting the electrodes 5 and 6, and thereby preventing the formation of a conductive path and the occurrence of ion migration.
