Title: Repairing method of retired drain pipes by moving extrusion molding
Inventor: JIN U SEOK
IPC: E03F3/06
Filed: 2000-03-28
Abstract: PURPOSE: A sewer pipe repairing and reinforcing method is provided to repair and reinforce the inside of a sewer conveniently by movably extrusion-molding the adhesive thermosetting resin, and to reduce working hours and expenses. CONSTITUTION: Two kinds of thermosetting resins having low viscosity are mixed, and extruded in a moving extruder(20) installed in a sewer pipe. A resin pipe(29) for repairing and reinforcing is formed with heating and hardening by contacting to the wall of the sewer pipe. The monomer thermosetting resin is extrusion-molded with cellulose for reinforcement of the resin pipe, and aluminum powder is added to the thermosetting resin to improve abrasion resistance. The mold release is formed to simply separate the resin pipe from the heating apparatus. The end of the sewer pipe is sealed with a cover(32) to form the resin pipe evenly. The cover is fixed in the extruder to the specific internal pressure of the cover in extruding the mixed resin, and the cover is separated from the extruder in filling the resin. The extruder forms the resin pipe in the sewer pipe by moving backward.

Abstract: PURPOSE: A sputtering reactor is provided to enhance bottom coverage and consistency of a thickness of a thin film, to consistently sputter corrosion surface of a target. CONSTITUTION: A sputtering device has a small rotatable magnetron(30) arranged opposite a target(16), wherein the magnetron(30) has a first magnet band(44) and a second magnet band(42) of opposite polarity arranged outside the first magnet band(44). The total magnetic flux of the first, inner magnet band(44) is less than that of the second outer magnet band(42). Some of the lines of magnetic flux from the second magnet band(42) pass through the first magnet band(44) and terminate at the second magnet band(42). The remaining lines of magnetic flux from the second magnet band(42) form a magnetic flux loop that encloses the first magnet band(44) and that terminates at the second magnet band(42). Consequently, the ability to confine electrons can be improved because no lines of magnetic flux extend beyond the vacuum chamber. The magnetron may be implemented with unbalanced magnet pairs of opposite polarity coupled through a magnetic yoke or may be implemented with outer cylindrical magnets of one magnetic polarity arranged in an oval or circular band extending from near the target center to the target periphery and inner cylindrical magnets of the opposite polarity arranged inside the band. The total magnet strength of the outer magnets should be at least 150% that of the inner magnets. The outer band is preferably in an oval shape having a minor axis no smaller than 0.8 of the major axis, and more preferably in a circular shape. The outer band either passes through the magnetron rotation axis or is located completely away from the axis.
