Abstract: A device for adjusting the tightening angle of a needle safety protector is proposed. The device is configured to provide an injection needle in an integrated state with a needle hub for preventing reuse of the injection needle and to fasten the needle hub to a needle safety protector that is disposed of in a folded state after use, a fastening structure is improved such that rotation is possible by a predetermined angle when the needle safety protector is rotated. Accordingly, an injection is safely performed by correcting the injection needle to the reference direction. In addition, even when a syringe is assembled by deviating from a reference angle during the mass production with the automatic line, the wrong angle is corrected in use.

Abstract: A plasma processing apparatus for generating plasma in a chamber maintained in a vacuum state and processing a substrate using the plasma. The plasma processing apparatus includes a refrigerant channel for circulating a refrigerant formed in a shower head, thereby easily controlling the temperature of the shower head and improving the reproducibility of plasma treatment.

Abstract: An ATM switching apparatus and method in which delay of ATM cells is prevented and multicast is implemented are disclosed. The multicast is determined by analyzing a received cell's destination address and the transfer times value. If there are several destination addresses, the same cell buffer address is stored in the respective destination addresses. By using the cell buffer addresses stored in the respective destination address, the cells are transferred until the transfer times value becomes zero. If the transfer times value becomes zero, the cell buffer address used at this time is stored into the cell buffer address storage unit making it available to use as an address for storing a new cell.
