  • Patent number: 11065034
    Abstract: An automatic hair implanter is capable of continuously performing hair transplantation work by applying a structure of a conventional manual hair implanter. The automatic hair implanter (hair transplantation device) comprises a rotating magazine therein, and several needle modules are stored in the magazine. Two pushrods, which are positioned on a rear portion of the device and capable of translational motion, play a role of pushing a needle and a shaft, which constitute a needle module, forward. The needle and the shaft may be moved backward by a spring positioned inside the magazine.

  • Publication number: 20120064233
    Abstract: Disclosed is a method of manufacturing an MMO anode using reel-to-reel continuous coating and heat treatment, including continuously coating a surface of a metal substrate with an MMO (Mixed Metal Oxide) coating solution using a continuous coater and passing the metal substrate through a heat pretreatment furnace and a heat treatment furnace to form an MMO coating layer on the surface of the metal substrate. When a long wire type MMO anode is manufactured, a uniform coating layer is formed thanks to the use of reel-to-reel continuous coating and heat treatment under uniform conditions, thus increasing durability and quality of the long wire type MMO anode. The exposure time of the metal substrate to the outside between the processes is minimized, and productivity is increased, thus decreasing the manufacturing cost to result in high product competitiveness.
