  • Publication number: 20130144268
    Abstract: A sealing vale cover used in a sputum suction pipe, which is mounted in a sputum suction pipe, includes a valve body and an elastic contractible cover. The valve body has a hollow interior and an open end. The elastic contractible cover seals the other end of the valve body. The inner wall surface of the elastic contractible cover is provided with a contact rib. The contact rib extends radially and outwardly from the top of an inner wall surface of the elastic contractible cover. The contact rib is formed with an arc-shaped surface on its protruding portion. When a long conduit of the sputum suction pipe is disposed through the elastic contractible cover, the arc-shaped surface of the contact rib is brought into contact with the outer surface of the long conduit, thereby preventing the leakage of the sputum.

  • Publication number: 20060252349
    Abstract: Disclosed herein is a semiconductor wafer polishing apparatus having a magneto-rheological elastic pad, in which the dielectric layer of the wafer fixed in the wafer holder to contact the abrasive coated on a rotating plate is polished. The semiconductor wafer polishing apparatus comprises a magneto-rheological elastic pad formed by a plurality of segments received to be fixed on the rotating plate; a plurality of electromagnets, having equal or larger diameter than that of wafer to selectively pressurize a part or the entire area of the wafer, which is arranged at the lower portion of the rotating plate in such a way that the central part accords with the central axis of the wafer holder; and a controller for selectively generating the magnetic field at a part or the entire part of the electromagnets.

  • Publication number: 20060186805
    Abstract: An organic EL device and a method for manufacturing the same are disclosed. The organic EL device comprises a substrate having a first electrode arranged on an active region, at least one organic material layer formed on the first electrode, a second electrode formed on the organic material layer so as to extend to an inactive region of the substrate to allow heat of the device to be dissipated to an outside therethrough, and a seal-cup facing the second electrode while being sealingly connected with the second electrode at a seal line via a sealant. The organic EL device can effectively lower an interior temperature of the device while preventing degradation thereof, thereby remarkably increasing lifetime thereof, and enhance interface stability of the device, thereby remarkably suppressing degradation in characteristics of the device.
