Abstract: In an anode side electrolytic domain (130), a radial flow is formed from an outer peripheral opening (131) to an inner side opening (141) of an anode side mesh electrode (140). Flows horizontal to the electrode surface of the anode side mesh electrode 140 are formed. Gases such as ozone generated from water electrolysis in the anode side electrolytic domain (130) are dissolved in raw water in the anode side electrolytic domain (130), and anode side electrolytic water is generated. Gas such as ozone that has been atomized by the anode side mesh electrode (140) comes into contact with the raw water, and high concentration anode side electrolytic water is generated. The anode side electrolytic water generated in the anode side electrolytic domain (130) flows in the inner side opening (141) of the anode side mesh electrode (140).

Abstract: Useful, new electronic devices are disclosed which utilize the huge polarization and electric double layer generated by excimer formation reaction in solid thin host films doped with excimer forming atoms (rare-gases and halogens: hereinafter, the parent atoms of excimers) at ambient temperature and pressure. A fundamental type of these devices is a single layer solid-state excimer device, which consists of a thin film fabricated by selecting a material from insulating metal oxides, at least one dopant from the parent rare-gas atoms (Ar, Kr and Xe) of excimers, and at least one dopant from parent halogen atoms (F, Cl, Br and I) of excimers. The dopants can be doped in the thin film during its fabrication process. Upper and lower electrodes can be added to the thin film when they are needed, and practical devices can be obtained by fabricating the electrodes and thin film together on a substrate.
