Abstract: An apparatus and method for deodorizing a gas mixture including air and a malodorous substance having a flow passage for the gas mixture and a fan for inducing air flow in a predetermined direction through the passage. An ultraviolet lamp for generating uv rays below a critical wavelength is in the flow passage for generating ozone from the air in the gas mixture. An ozone-decomposing catalyst layer is in the passage for contacting the gas mixture, and an ozone-decomposing ultraviolet lamp for generating uv rays above critical wavelength is positioned to irradiate the layer directly. The intensity of the radiation of the two layers is controlled to avoid the discharge of ozone from the downstream end of the passage.

Abstract: A deodorizing apparatus adapted to be placed in an enclosure to deodorize the bad smelling components of the foul air within the enclosure. The body has an interior free space and a ozone-decomposing layer. Ozone is generated within the free space and flows in contact with the layer so that it is decomposed before it can leave the body. The ozone is formed either by silent (corona) discharge or by ultraviolet radiation in the free space, and the energy supplied is sufficient to cause the ozone to flow outwardly into contact with the layer and to draw in foul air through the layer so that the decomposing ozone effectively deodorizes by oxidation the bad smelling components. The flow through the device is sufficient to deodorize the entire enclosure.

Abstract: The sliding contact surface of the main body of a seal component, such as an automotive weather strip or glass run, is provided with the lubricating coating formed from a UV-curing coating material, whereby the drawbacks of the prior art seals, such as the problems of useful life, sealing, whistling sound, sound insulation and manufacturing cost can be overcome.
