Abstract: A safety electric socket in which two spring-supported doorplates are respectively pivoted to a holder block to block the neutral and hot slots against outside dust and water and to stop the spring-supported on/off switching button from downward movement. The doorplates are opened for allowing downward movement of the switching button to switch on power supply when the neutral and hot blades of an electric plug are respectively inserted into the neutral and hot slots.

Abstract: A composition of human interferon-alpha (IFN-?) subtypes produced from human lymphoblastoid cells is disclosed. These purified IFN-? composition comprise higher specific activities and may be applied in the treatment of cancers, viruses, and immuno diseases.

Abstract: The present disclosure pertains to an integrated post-etch treatment method which is performed after a dielectric etch process. Using the method of the invention, byproducts formed on the sidewalls of contact vias during the dielectric etch process can be removed efficiently. The method of the invention also reduces or eliminates the problem of polymer accumulation on process chamber surfaces. An overlying photoresist layer and anti-reflection layer are removed during the performance of the post-etch treatment method. Typically, after the etch of a dielectric material to define pattern or interconnect filling spaces, a series of post-etch treatment steps is performed to remove residues remaining on the wafer after the dielectric etch process. According to the method of the present invention, a post-etch treatment method including one or more steps is performed after the dielectric etch process, preferably within the same processing chamber in which the dielectric etch process was performed.
