Abstract:
PURPOSE: An opening and closing valve for a harmful gas incinerator is provided to prevent the melting and corrosion of a valve due to heat by installing Teflon gasket. CONSTITUTION: An opening and closing valve for a harmful gas incinerator comprises a cylinder(302), front and back covers(305,312), a cover(309), a first gasket(308), a blocking plate, a valve room(314), and a rear cover ring. The cylinder is installed in the front cover. The first gasket seals a through-hole through which a cylinder rod passes. The cover is fixed to the front cover to the first gasket with being pressed. The rear cover prevents the separation of the first gasket. The blocking plate is combined in the leading end of the cylinder rod. The valve room comprises a through hole and a third gasket. The through hole is opened and closed to the reciprocation of the blocking plate. The gas pipe is shut tightly by the third gasket. A fourth gasket of the rear cover ring is closely combined in the through hole of the valve room.

Abstract:
PURPOSE: An electromagnetic engine is provided to accomplish high power by attaching a permanent magnet to the top and side surface of a cylinder. CONSTITUTION: An electromagnetic engine comprises a head(100), a cylinder(200), and a crank body(304). A first permanent magnet is arranged inside the head. A second permanent magnet is attached to the exterior wall of the cylinder. The permanent magnet bar is arranged in the center of the piston. The first and the second permanent magnet and a permanent magnet bar push the piston. An enamel copper wire is wound in the piston. The piston generates induced electricity with a reciprocation movement.
Abstract:
PURPOSE: A vortex water power generator is provided to stably generate electricity by installing a water power generator of the high efficiency by increasing the current speed of water. CONSTITUTION: A vortex water power generator is composed of a horizontal guide pipe(100), a vortex guide pipe(200), a hopper, a turbine, and a generator. A bottom and both sides are combined so that section is formed in a U shape to make water flow in one way in the horizontal guide pipe. The vortex guide pipe is formed in a cylindrical shape having the diameter which is twice or more as large as the width of the horizontal guide pipe to generate vortex. The hopper is installed in the lower end of the vortex guide pipe and changes the flow speed rapidly. The turbine is installed in the lower end of the hopper and is rotated by water passing the hopper. The generator is connected to the turbine and generates electricity by self-revolving with the rotary force of the turbine.
