Abstract: An impact beam for car doors is reinforced at its central portion. In an embodiment, the impact beam consists of a longitudinal beam stepped at two positions to allow its central portion to be thicker than its opposite end portions. In another embodiment, the impact beam consists of a longitudinal base beam body, and a hollow reinforcing beam body having a length shorter than that of the base beam body and a sectional size larger than that of the base beam body, and fitted over a central portion of the base beam body. The impact beam further comprises a beam bracketing structure for fastening the opposite ends of the impact beam on a door panel. This beam bracketing structure consists of two support brackets fixedly mounted to the door panel, and a locking mechanism for locking each end of the beam to an associated one of the two support brackets.

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 composite material ball screw is provided to improve a damping efficiency by inserting a composite material shaft member into the center of the screw and to stably drive at a high speed by increasing natural frequency. CONSTITUTION: A composite material ball screw includes a hollow shaft(11) having a screw thread(15) on an outer circumference and a composite material shaft member(12) fixed in the center along an axial direction to have a space for forming sliding friction with an inner surface of the hollow shaft through the vibration. Since the composite material shaft member is fixed only at both ends of the hollow shaft, vibration energy is vanished to friction energy due to sliding friction between the inner surface of the hollow shaft and the outer surface of the composite material shaft member to make the attenuation action become large.
