Title: Device for welding curved plate
Inventor: CHOI WON HONG
IPC: B23K37/02
Filed: 1998-12-30
Abstract: PURPOSE: A device for welding a curved plate is provided to control movement by using four-shaft moving apparatus in a robot type having a perpendicular coordinate and to finely adjust location by being connected to the lower end of a slider at the perpendicular shaft of the four-shaft moving apparatus. CONSTITUTION: A weaver(330) is installed in perpendicular to a touch(310) for being reciprocated for a certain distance in the same structure with a slider(320) of adjusting arch length. The traveling speed of various driving units installed on a traveling table(210) is reduced by a traveling motor. Then, the driving units are traveled along a guide rail by converting rotational force into linear movement by using the combination of a rack gear and a pinion gear. Herein, the touch is prepared for a plane linear welding by an angle adjusting joint(340) and a perpendicular shaft slider(360). And, every driving units except the traveling unit move to the center of administration or an initial point for being in an initial state. A contacting sensor detects the location of a curved unit while welding a material along the welding line by the traveling of the touch. Thus, the traveling speed is reduced while the angle of the touch is adjusted by the rotation of a rotating shaft according to the angle of the curved unit.

Filed: 1998-12-31
Abstract: PURPOSE: A method for disk unit state management during standby roaming of wireless communication switchboard is disclosed to enable the main processor, which has been converted into active state to access the hard disk with new management program, during the main processor's active/standby procedure to applicate new management program. CONSTITUTION: A method for disk unit state management during standby roaming of wireless communication switchboard is composed of activation, conversion, execution, and completion. A's OMP checks for input of new program in B's hardware, which is in standby state and if inputted, A's OMP separates A and B's hard disks. Active A's OMP leads new management program stored in idle B's hard disk and loads it in idle B's OMP and its main processor. A's OMP activates B's active/standby procedure movement and B's hardware is switched to active state. Active B's hardware checks A's main processor state to see if it is "OLD". If not, process is rerouted to step where B's active/standby procedure is activated. If "OLD", B's OMP converts A's hard disk's state into "OLD". B's OMP decides to either execute new management program or not. If yes, B's hard disk information is copied in A's hard disk, completion of process is confirmed and if not properly completed, error message is returned to user copy process is repeated. If completed correctly, A's hard disk is switched to standby state.
