Title: 10M Target Transferring Equipment Using Micro Controller
Inventor: LEE HAE SEONG
IPC: F41J5/00
Filed: 2000-12-29
Abstract: PURPOSE: A 10m target conveying apparatus is provided to improve the convenience of use and increase the endurance of a shooting equipment by easily conveying a shooting target using a micro controller. CONSTITUTION: A power is supplied when a user pushes an operating switch. At this time, the operation starting state is alarmed by JP1 for connecting a button and a lamp. Then, a motor is operated after reading a software state using U1 and a current value is checked so as to determine whether the shooting target reaches a destination. If the shooting target does not reach the destination, a circuit is operated to move the shooting target forward and backward directions. The operation of the circuit is stopped when the user pushes the switch one more. At this time, the current flow in the circuit is automatically shut down. In this state, when the user pushes the switch one more, the current flow is regenerated so that the shooting target is moved forward or backward in reverse direction.

Abstract: PURPOSE: Provided is a reduction method of nitrogen oxides and sulfur oxides from exhaust gas by using hydrogen peroxide solution and calcium hydroxide solution. CONSTITUTION: The method comprises the steps of (a) injecting 17-25 wt.% of hydrogen peroxide solution heated to a temperature in a range of 350-550°C and calcium hydroxide solution heated to a temperature in a range of 200-550°C into a reaction tank(2) filled with exhaust gas through injection nozzles(3) connected to a reactants tank(4), (b) spraying water to reacted compounds (nitrogen oxides) produced in the reaction tank(4) and transferred to a cooling tower(5) through nozzles(6) so as for the reacted compounds (nitrogen oxides) to become liquid, (c) collecting the nitrogen oxides liquid into a solid waste storage pit(7) installed at a lower portion of the cooling tower(5), (d) separating calcium sulfate (CaSO3) of a solid state.
