  • Patent number: 10654629
    Abstract: There are provided a check valve structure that not only prevents backflow of fluid but does not discharge fluid for unintended pressure in a correct direction, and a squeeze container using the check valve structure. A squeeze container includes a container and a nozzle member attached to an opening of the container. The nozzle member is provided with a check valve structure that is closed in an unloaded state, and that blocks a flow of fluid from downstream and allows a flow of fluid from upstream. The check valve structure is opened when an elastic valve element elastically deforms in two stages due to pressure of fluid from upstream (container).

  • Publication number: 20120271252
    Abstract: Disclosed is a medical fluid nozzle which makes fluid drops less likely to remain at its tip portion after the medical fluid is dropped. The medical fluid nozzle 1 is a substantially cylindrical shape with a tip surface formed in a substantially planar shape. An annular ridge 10 is formed along the circumferential direction at the tip portion of the medical fluid nozzle 1. The ridge 10 is formed so as to be continuous with the tip surface of the medical fluid nozzle 1 and has an extended surface 11 formed with an increased diameter so as to be flush with the tip surface of the medical fluid nozzle 1.

  • Publication number: 20110142206
    Abstract: A method includes selecting a first set of digital subscriber lines (DSLs) supported by a digital subscriber line access multiplexor (DSLAM). The DSLs of the first set exhibit reduced performance based on historical performance data. The method includes sending a request to the DSLAM for a first performance parameter for each of the DSLs of the first set. The method includes receiving the first performance parameters. The method includes removing DSLs from the first set that have suitable performance based on the first performance parameters to create a second set of DSLs. The method includes selecting a line profile to apply to the second set of DSLs. The method also includes sending a second request to the DSLAM to apply the line profile to the DSLs of the second set and then to determine a second performance parameter for each of the DSLs of the second set.
