  • Patent number: 8789540
    Abstract: The present invention provides a novel structure for sealing a cosmetic container using a double-injection molded rib on the container body sealing against a deformable hard-rubber ring on the container cover. The invention will maximize product reliability by improving the sealing structure of a make-up base or cosmetic container through providing a clear, air-tight effect since the sealing structure cannot be deformed, even in the case of long-term use. The invention provides uniform, airtight adhesion without unequal distribution of coupling intensity between internal sealing components when the container cover is closed. Further, the aesthetics of the container are increased because a closure clasp is not necessary, and it is possible to eliminate the problem of dried-out product created when the container is fitted with a closure clasp or similar device.

  • Patent number: 8293612
    Abstract: A method for manufacturing a lateral double diffused metal oxide semiconductor (LDMOS) device includes forming an oxide layer on a semiconductor substrate, forming first and second trenches by partially etching the oxide layer and the semiconductor substrate, forming a small trench overlapping with the second trench so that the second trench has a stepped structure, and depositing one or more dielectric layers so that the first trench forms a device isolation layer defining a semiconductor device region and the second trench having a stepped structure forms a drain extension device isolation layer. The breakdown voltage of the LDMOS device may be improved while reducing the on-resistance, thereby improving the operational reliability of the device.
