摘要： PURPOSE:To improve decoloring and coloring by light and decoloring and coloring sensitivity by simultaneously subjecting the color developing layer of an opto-electrochemical element to the impression of an electrochemical oxidation o reduction potential and photoirradiation. CONSTITUTION:After transparent electrodes consisting of ITO, etc., are formed on a transparent substrate consisting of glass, etc., the color developing layer of a transition metal oxide is formed by a vapor deposition method to form a coloring developing substrate. The transition metal oxide is exemplified by WO3, MoO3, etc. The color developing layer of the opto-electrochemical element having the color developing layer contg. the transition metal oxide in such a manner is simultaneously subjected to the impression of the electrochemical oxidation or reduction potential and the photoirradiation. Thereby, the photoelectric current direction is controlled by the impressed potential, the coloring and decoloring by light are executed in this way and the high-density coloring and high-sensitivity coloring and decoloring are executed by the synergistic effect of light and oxidation or reduction current.

摘要： PURPOSE: To provide a deodorizing/disinfecting apparatus which conducts regeneration of a deodorant by removing odorous substance and bacteria by adsorption corresponding to a short-time high load deodorization while decomposing and disinfecting the odorous substance adsorbed under a low deodorizing load. CONSTITUTION: A deodorizing/disinfecting apparatus contains one deodorizing space 15, a deodorizing sheet 10 having a desired area arranged in the deodorizing space 15 free to run and an ultraviolet ray source 13 arranged in proximity to the deodorizing sheet. The deodorizing sheet 10 carries a whole amount of deodorant to match a short-time high deodorizing load. This enables applying of the total irradiation of ultraviolet ray to the deodorant as a whole to be carried with the running of the sheet to match photodecomposition rate and the deodorant mainly comprises a photoreactive semiconductor and an adsorbing substance.

摘要： PURPOSE:To reduce the load of a blower motor by applying voltage across a plurality of conductive porous layers laminated by interposing permeable non-conductive layers in an air filter for an air cleaner for air conditioning or the like. CONSTITUTION:Two conductive porous layers 1 or more are laminated by interposing air permeable non-conductive layers 2 composed of a non-woven cloth or the like used as a filter medium to constitute a filter. For the conductive porous layers 2, wet and dry non-woven cloth containing conductive fibers or the like is used mostly, although not particularly specified. A non-woven cloth sheet into which metallic fibers are contained is used for the purpose. Power source terminals 5 connected with cathodes or anodes of a power source are disposed respectively on the conductive porous layers 1, 1, connected with the power source and voltage is applied among the conductive porous layers 1, 1. Also folding work can be carried out to increase the filter area.

摘要： PURPOSE:To decrease a required UV exposure and to improve color developing density by having a 1st color developing process by light inclusive of wavelength light of the intrinsic absorption wavelength end of a transition metal oxide and a 2nd color developing process by the reducing current of a color developing layer. CONSTITUTION:The photoirradiated parts of an optical electrochemical element are slightly developed in colors and the absorption is generated in a visible light area by the 1st color developing process by the light inclusive of the wavelength light of the intrinsic absorption wavelength end of at least the transition metal oxide. Since the oxidation reduction potential and resistance value of the color developed parts change, the more reducing current flows from the higher potential than in the unirradiated parts flows in the photoirradiated parts and further, these parts darkly develop colors. The required UV exposure is decreased in this way and the color developing density is increased.
