  • Patent number: 6461369
    Abstract: The present invention discloses a hair trasplanter. A needle to be inserted into a scalp has a pointed end portion to reduce damage of the scalp, and a guide plate in adhered to an end portion of a sliding unit reciprocating in the longitudinal direction of the needle outside the needle, in order to prevent hair roots from being separated at the time of the separation of the needle. As a result, the hair roots inserted into a needle insertion groove are not damaged and are naturally settled in the scalp without modification, thereby stably performing the hair transplantation.

  • Patent number: 6285717
    Abstract: A digital video encoder for a digital video system wherein digital video data output from an MPEG decoder is input and an analogue composite video baseband signal (CVBS) is output comprises first selection means for selectively outputting first and second clocks in response to a first selection signal, signal dividing means for dividing the input digital video data into a luminance signal and a chrominance signal in response to the output of the first selection means, luminance signal processing means for regulating the gain and offset of the luminance signal, adding a synchronizing signal to the regulated luminance signal, and filtering a low band component of the luminance signal to output the filtered signal as a digital luminance signal, chrominance signal processing means for regulating the gain of the chrominance signal, interpolating the gain-regulated chrominance signal, producing color difference signals, interpolating the produced color difference signals, filtering a low band component of the inter

  • Patent number: 5891388
    Abstract: An Fe--Mn Vibration Damping alloy steel having a superior tensile strength is disclosed. The alloy steel consists of, by weight percent: 10 to 24% of Manganese(Mn); up to 0.2% of carbon(C); at least one element selected from the group consisting of 0.1 to 2.0% of Titanium(Ti), 0.1 to 2.0% of Molybdenium(Mo), 0.1 to 1.0% of Vanadium(V), and 0.1 to 0.7% of Tungsten(W), the element increasing a tensile strength of the vibration damping alloy steel; and remaining iron(Fe) and incidental impurities. Further, an Fe--Mn vibration damping alloy steel having a good corrosion resistance is disclosed. The alloy steel consists of, by weight percent: 10 to 24% of Manganese(Mn); up to 0.2% of carbon(C); at least one element selected from the group consisting of 0.1 to 4.5% of Chromium(Cr), 0.1 to 1.5% of Copper(Cu), and 0.1 to 1.1% of Niobium (Nb), the element increasing a corrosion resistance of the vibration damping alloy steel; and remaining iron (Fe) and incidental impurities.
