A self-regenerating, self-cleaning hydrophobic surface is formed when particles are secured on a carrier that is itself a mixture of particles and binder. When particles on the surface are ablated by erosion, new particles in the carrier are exposed to regenerate the self-cleaning surface, resulting in a long-lasting self-cleaning action. The self-cleaning surface may be used with particular advantage outdoors, e.g. on vehicles, where self-cleaning materials are particularly exposed to the effects of the environment. |

An electronic device substrate, such as a semiconductor silicon wafer or a liquid crystal glass substrate, with a surface which has just undergone cleaning treatment and which is covered with a clean oxide or nitride film which will readily adsorb organic contaminants is treated with an aqueous solution containing choline, or alternatively a similar substrate which has not been cleaned is treated with a treatment solution comprising a SC-1 solution to which choline has been added. Following drying, a surface concentration of choline of between 5null1010 moleculesnull7null1012 molecules/cm2 is adsorbed onto the substrate surface. This treatment suppresses organic contamination of the substrate from the atmosphere. As a result, the surface carbon concentration of an electronic device substrate can be suppressed to a value of no more than approximately 3null1013 atoms/cm2, even for manufacturing processes carried out in typical clean rooms with no chemical filters installed. |

There are described apparatus and methods wherein ultraviolet light kills and/or degrades and vaporizes microorganisms and organic material which naturally form over time on a heat exchanger. As this matter is eliminated, the pressure drop is decreased (i.e., airflow is increased) and the heat exchange efficiency (capacity) is increased. Less energy per Btu removed is used by the cooling system, and less energy is used by the HVAC system to move air. |

A protection system for a conveyor for items, such as food items, is provided to keep the conveyor free from bacteria and other contaminants which may accumulate and build-up on the conveyor track and track traversing components. The protection system includes a shroud surrounding the conveyor to which pressurized, bacteria-free air is fed. A preferred bacteria removal unit is a filtration unit to filter bacteria from the ambient air. Herein, a combination filter and blower unit is disclosed which finely filters ambient air, preferably down to 3 microns, and pressurizes the air and blows it into an air manifold connected to the shroud by a series of air ducts. The shroud walls cooperate to form a slot through which the meat hangers can extend and for allowing the clean air in the shroud to be continually flowed therethrough and circulated around the conveyor components. A cleaner, such as a steam cleaner, can be located at a predetermined position along the track between the unloading and loading stations for the meat transported by the conveyor. The protection system herein advantageously keeps the conveyor clean and sanitized during conveyor operations without requiring costly conveyor shutdowns for cleaning and maintenance. |

The water drop removing apparatus for a camera lens assembly is arranged to automatically wipe off water drops or the like attached on the front face of the lens assembly to make field shooting in rainy or snowy weather easy. Injection nozzles consisting of a soft tube in the number of three, for example, are disposed on the top edge and each side edge in such a manner that they are mounted to be rocked around a rocking shaft by a motor or an air rocking mechanism. Each of the injection nozzles are connected with an electromagnetic valve, an air pump, or the like. The three injection valves are rocked fanwise in an order to inject air onto the face of the shooting window through the injection nozzles during the forward period of this rocking. The nozzles on each side is rocked from top to bottom. This causes the water drops attached on the front face of the shooting window to be automatically removed, so that there is no need to wipe off water drops with cloth or the like. In addition, the injection nozzles may be automatically operated at rainfall by using a rainfall sensor. |
