  • Publication number: 20250090745
    Abstract: A medical liquid injection device includes: a reservoir assembly storing medical liquid in a storage space defined by a reservoir and a plunger moving linearly inside the reservoir, a needle assembly connected fluidly to the reservoir assembly to discharge the stored medical liquid, and a driving unit transmitting a driving force generated by a driving module to the plunger. The driving unit includes a rod member coupled to the plunger to move linearly together with the plunger, a wheel member rotating by the driving force, and a connection member having a catching portion that is movable in an axial direction of the wheel member and the rotation thereof with respect to the wheel member is limited around the axial direction.

  • Patent number: 9403936
    Abstract: A method for preparing a pitch for carbon fibers and a pitch for carbon fibers prepared by the same are disclosed. The method includes introducing a peroxide compound and ozone into a petroleum-process residual oil, followed by heat treatment for reaction. By the method, the pitch for carbon fibers, which exhibits excellent oxidative stabilization and oxidative incompatibility while having a high softening point and high strength, can be obtained at high yield at a relatively low temperature.

  • Publication number: 20110186414
    Abstract: A dome switch integrated touch window for a mobile terminal includes a lower substrate, a dome switch, a spacer sheet, and an upper substrate. A dome switch is disposed on a lower substrate to correspond to a contact terminal. The dome switch extends through a spacer sheet and an upper substrate disposed on the spacer sheet. The dome switch is covered by a design film. The dome switch includes an operation member having a resilient base disposed over the contact terminal and a resilient protrusion projecting from the resilient base, and a dome disposed between the operation member and the lower substrate. The operation member may have an upwardly concaved dome-shaped groove to receive the dome.
