Title: Automatically Loaded Exparnder for steam generator
Inventor: PARK GI TAE
IPC: B21D39/20
Filed: 2000-12-29
Abstract: PURPOSE: An expander is provided to automatically mount or separate the expander by installing a spring made of high elastic material, a spring guide and a bearing between an expander cage and a mandrel. CONSTITUTION: An expander includes a cage, a mandrel movably inserted into the cage, a plurality of rolls, and a lock nut. A spring(70) made of high elastic material, a spring guide(80) and a bearing(90) are installed between the expander cage and the mandrel so that the expander can be automatically separated from a tube when a reverse rotational force is applied thereto. If the rotational force is applied after enlarging the tube, the expander is forced in a direction against the compressing force of the spring(70) so that the expander is automatically separated from the tube due to the restoring force of the spring(70).

Title: depositing of device for compact disk
Inventor: CHUNG JI WOO
IPC: G11B33/04
Filed: 2001-04-24
Abstract: PURPOSE: A device for keeping a compact disk is provided to keep the compact disk by upward and downward sliding a moving cover panel part, thereby using a keeping package for a long time and providing various designs of the keeping package. CONSTITUTION: A device for keeping a compact disk includes a bottom panel part(30) securing the compact disk, a moving cover panel part(10) inserted into the bottom panel part, and opening and shutting by moving forward and backward to attach and detach the compact disk, wherein the bottom panel part includes a securing part(34) having inner and outer projections for preventing movement of the disk, insertion parts(31) each having a concave part formed at right and left outer peripheral surfaces and an inclination part(32) formed in the center of the outer surface of the upper protrusion, an operating hole(33) forming a groove to prevent movement by putting a finger of a user; the moving cover panel part includes a guide cover surface(14) downward formed at right, left, rear end surfaces, a cut part(11) formed by cutting the upper surface of the guide cover surface, moving bars(12) formed at the right and left inner wall of the cut part, preventing projections(13) formed with the moving bars with maintaining regular gaps for inserting a print from the outside.
