Title: Method for producing welding wire rod of small tensile strength deviation
Inventor: KWON JEONG SEOK
IPC: C21D8/06
Filed: 1998-12-19
Abstract: PURPOSE: A method for producing a wire rod of welding rod is provided to minimize the deviation of tensile strength between the overlapped part and the central part of the wire rod. CONSTITUTION: A billet contains 0.02-0.10wt% of C and 0.003-0.021wt% of Ti for being heated at a temperature of 900-1010°C. The billet is continuously hot rolled for being wound up at the temperature of 800-950°C. Then, the billet is cooled for being 700-750°C at a cooling speed of 2-5°C/sec and for being 600-650°C at the cooling speed of 1°C/sec. Herein, the standard deviation of tensile strength in a ring is under 1.25. The wire rod is rapidly cooled after being wound up to reduce the growth time of TiC precipitate. Then, the wire rod is slowly cooled after deformation for reducing the deviation of tensile strength in the ring.

Filed: 1998-12-24
Abstract: PURPOSE: A device for continuously loading and unloading powdery material is provided to prevent environmental pollution due to leakage of oil, to dispose a small amount of material remaining in the bottom of a ship and to remove iron pieces or metal pieces mixed in a material. CONSTITUTION: By starting a motor(41), the material sucked with air via a suction hole(34) is transferred to a loading unit(35) by passing through a closed pipeline(33). The sort and particle size of the material(11) is confirmed by a camera attached adjacently to the suction hole in an operation chamber(18). The strength of air of a blower(40) is determined according to the sort and particle size of the material and the size of the pipeline whereby the material is sucked. Most of the material flowed into the loading unit is deposited on the bottom by the weight of itself. A portion of the material passes through a filter(37) with air. The sucked air is vented out to atmosphere by passing through the filter and the material mixed in the air is attached on the filter. If material more than a certain amount is deposited on the filter, corresponding valves(38) of the filters are sequentially opened. The attached material is shaken off by using a vibration generator(39) and then loaded on the loading unit.

Abstract: An improved method is disclosed for forming a strata of overlapping sheets suitable for use in a pop-up dispensing system. The sheets are cut from ribbons having at least one side edge which has a knee-like protrusion, with the opposing side edge being either, substantially parallel to the longitudinal axis of the ribbon, or having one or more knee-like protrusions formed on the opposing edge. The ribbons are then phased so that the knee-like protrusion on one edge aligns with either the essentially parallel edge of an adjoining ribbon or a knee-like protrusion on the side edge of the adjoining ribbon. Phasing can be accomplished by either, aligning knee-like protrusions on the side edges of adjoining ribbons, or reversing the orientation of the side edges of alternating ribbons. After phasing, the ribbons are overlapped creating a series of predetermined, areas of greatest overlap adjoining areas of least overlap such that successive ribbons are bonded only by the interfacial interaction between ribbons. By overlapping multiple ribbons in this manner a strata is formed which is then folded to interleave the ribbons. A resulting stack of interleaved ribbons is cut to form blocks of individual interleaved sheets. The process can be accomplished manually or in a continuous production process.

Abstract: PURPOSE: An apparatus for detecting a frame starting point of a frequency hopping(FH)/orthogonal frequency division multiplexing(OFDM) communications system is provided to make a transmitter transmit data frames inserting synchronous symbols designating synchronous patterns, and to make a receiver detect the synchronous patterns of the synchronous symbols, so as to exactly detect the frame starting point without an energy arithmetic operation. CONSTITUTION: A frequency hopping(FH)/orthogonal frequency division multiplexing(OFDM) data frame inputted to a frame detector(300) is inputted to a correlator(310). The correlator(310) detects a synchronous symbol of the FH/OFDM data frame, and detects synchronous patterns of predetermined bits of the synchronous symbols, then calculates correlations of the synchronous patterns to output the calculated correlations to a correlation detector(320). A threshold comparator(325) inputs the correlations to detect the correlations as valid correlations, only when correlations under a low threshold value and over a high threshold value are detected, and performs a data demodulation. A guard interval remover(330) removes a guard interval inserted into a frame transmitted from a transmitter, and outputs a data frame starting point to a serial to parallel(S/P) converter(340). The S/P converter(340) converts data of the guard interval remover(330) in parallel, and outputs the parallel data to a fast Fourier transform(FFT) block(350). The FFT block(350) applies an FFT to the parallel data to calculate phases and amplitudes of each carrier frequency component, and outputs the parallel data to a parallel to serial(P/S) converter(360). The P/S converter(360) converts the parallel data in serial to output the serial data to a signal demodulator(370). The signal demodulator(370) inputs the serial data to demodulate the serial data to original data, then outputs the original data.
