[Object] It is an object of the invention to provide a cleaning apparatus for cleaning a precision substrate capable of preventing a contamination factor from adhering again, to prevent a natural oxide film from being formed, and to prevent a water mark.[Solving Means] In a cleaning apparatus 1, a substrate-to-be-cleaned 2 is disposed in a container 3, and an atmosphere component measuring device 4 which measures an atmosphere in the container 3, gas supply means 5 for controlling an atmosphere, and gas discharge means 6 and 7 are disposed in the cleaning apparatus 1, the cleaning apparatus 1 includes at least one the gas supply means 5 which equally supplies gas from a portion opposed to a surface-to-be-cleaned, gas supply means 21 for supplying gas to a rotating/holding mechanism comprising a cylindrical stationary shaft 16, a fluid bearing 17 and a rotation support member 18, gas discharge means 7 for discharging gas into a drainage mechanism, and gas supply means 31 for supplying gas for controlling an atmosphere when cleaning liquid is injected. The atmosphere component measuring device 4 which measures the atmosphere in the cleaning apparatus 1 can measure at any timing, and can detect one or more of a flammable component, a combustible component and a oxdizer component.
摘要:
A plurality of liquid chemicals are fed onto a substrate to be treated, which is held and spinned, and the liquid chemicals scattered from the substrate to be treated by a rotator are separately recovered in respective recovery tanks (16 to 19) by each chemical. A lifting mechanism controls lifting operation of respective fences (3a to 3s) which form respective recovery tanks (16 to 19) so as to recover the liquid chemical into a certain recovery tank, while at the time, inlets of the other recovery tanks are closed at that time. Such a lifting mechanism includes a fence lifting plate provided with a cams portions 29a engaging with the respective fences (3a to 3d) to lift the corresponding fence, and performs lifting operation of the respective fences (3a to 3d) by rotating the fence lifting plate (29) around the shaft of the fence lifting plate (29) by a motor (34) so that the liquid chemical to be recovered is prevented from mixing in other recovery tanks.
摘要:
Method using oxygen removal for extending the useful shelf-life of refrigerated red blood cells. A cost-effective, 4.degree. C. storage procedure that preserves red cell quality and prolongs post-transfusion in vivo survival is described. Preservation of adenosine triphosphate levels and reduction in hemolysis and in membrane vesicle production of red blood cells stored at 4.degree. C. for prolonged periods of time is achieved by removing oxygen therefrom at the time of storage; in particular, by flushing with an inert gas. Adenosine triphosphate levels of the stored red blood cells are boosted in some samples by addition of ammonium phosphate.
