Abstract: 본발명은 국토개발에 따른 도로제반 건설, 철도레일공사나 택지 개발 공사등 산업건설 현장에서 발생되는 나무뿌리(일명 : 통목근)의 폐기물의 효율적인 처리 방법 및 재활용을 할 수 있는 방법에 관한 것이다. 
     종래에는 상기 나무뿌리를 폐기하기 위하여 땅속에 매립하거나 소각시키는 방법으로 폐기 처리를 하였으나, 땅속에 매립하는 경우에는 다량의 부피가 큰 통목근을 비좁은 토지 속에 매립시키는 과정에서 지반이 약하여 토지를 이용할 수 없게 되었고, 소각시켜 매립하는 경우에는 수분이 함유된 통목근을 완전 연소시키려면 오래시간 동안 고열로 소각시켜야 함으로서 많은 에너지의 낭비를 초래 하였던 것이다. 
     따라서 본 발명은 상술한 제반 문제점을 해결하고자 발명된 것으로서 별도의 통목근 분리 장치를 제공하여 통목근을 원활한 방법으로 분쇄 및 분리하여 본 발명의 공정에서 발생되는 굵은입자 및 작은입자와 미립자는 입자의 크기별로 3단계로 분리하여 굵은 입자 (톱밥크기이상)는 땔감으로 사용하게 하고 작은 입립자 (톱밥크기이하)는 축사 청소용 보료나, 작물용 퇴비로 사용하고 미립자(고분자)는 재활용 종이의 원료인 펄프로 재활용하게 함을 목적으로 발명된 것으로서 본발명을 적용시키게되면 실제로 폐기되는 양은 극히 적은 양으로서 다량의 토목근 폐기량를 1/10이하로 축소시켜 매립시킬 수 있도록한 특징이 있게한 것으로서 본 발명은 수집된 통목근을 세척시키는 세척부(B) 와 이를 소정의 크기로 절단하는 절단부(C)와다시 절단된나무를 파쇄시키는 파쇄부(D)를 설치하고, 파쇄되어 잘게 찢어진 목근조각을 최종적으로 로울러분쇄부(F)의 로울러 분쇄기(16)에 의하여 분쇄시킨 입자를 3단계(굵은입자, 작은입자,미세입자)로 선별할 수 있는 선별부(G)로 선별케하고 선별된 입자를 소각부(H)에 의하여 소각시켜서 완전 연소된 재를 수거하여 연소된 재는 작물재배용 퇴비로 재활용하거나 매립시켜 폐기시키고 굵은입자는 땔감으로, 작은입자는 축사청소용보료나 작물재배용퇴비로, 미세입자(분진)는 재활용종이의 원료인 펄프의 재료로 재활용할 수 있게한 나무뿌리(통목근)의 효율적인 폐기 및 재활용 장치인 것이다.

Abstract: PURPOSE: To compensate for fluctuations in the static magnetic field for a MRI apparatus. CONSTITUTION: RF probes 1P1, 1P2 are placed, and standard, static magnetic field is measured as a standard frequency at first. Then, the static magnetic field is measured as a frequency at a right time. Amount of the fluctuation in the static magnetic field is acquired from the difference. A frequency for transmitting RF pulses and a detecting frequency for receiving NMR signals or a gradient current are corrected to compensate for the amount of the fluctuation. As a result, fluctuations in the static magnetic field caused by movements of any metal objects near a MRI apparatus such as passages of a train or changes in the environment such as changes in the temperature can be compensated.

Title: Fingerprint sensing device and method using time-variable property of fingerprint signal
Inventor: KIM WON CHAN
IPC: G06K9/00
Filed: 2002-03-09
Abstract: PURPOSE: A device and method for recognizing a fingerprint is provided to detect an inherent fingerprint pattern from a time value necessary for achieving to a specific reference value of a fingerprint signal. CONSTITUTION: If a fingerprint is contacted with a fingerprint sensing device, a fingerprint signal creation unit(110) creates an analogue fingerprint signal(VSP) which reflects a change/discharge characteristic of a fingerprint impedance in each sensing point. The analogue fingerprint signal(VSP) is converted into a digital coefficient signal in a signal conversion unit(120). The digital coefficient signal is processed in a signal processing unit(140). An inherent fingerprint pattern of a corresponding fingerprint is detected. The signal processing unit(140) executes a feedback of a signal process result to a control unit(130). The control unit(130) analyzes the feedback signal and applies a control signal(Sc) to a reference signal generating unit(150) and a clock signal generating unit(160) for detecting a detailed fingerprint pattern. A size of a reference signal(Vref) and a period and a generating time of a clock signal(Sclk) being applied to the signal conversion unit(120) are adjusted by the control signal(Sc). The control unit(130) supplies an enable signal(EN) to the fingerprint signal creation unit(110) and the signal conversion unit(120). The enable signal(EN) is used for adjusting a supply of an electric charge in the fingerprint signal creation unit(110) and used for adjusting a coefficient point of a clock signal in the signal conversion unit(120).
