Abstract: PURPOSE: An ADSL(Asymmetric Digital Subscriber Line) system in which symmetric/asymmetric services are available, and method for maintaining and managing a transmitting/receiving link thereof are provided to perform a symmetric/asymmetric service for providing a symmetrical type bidirectional high speed/low speed service and an asymmetrical service to a subscriber using one coaxial line. CONSTITUTION: An ATM(Asynchronous Transfer Mode) cell bus interface unit(101) receives an ATM cell signal outputted from an ATM cell bus, and performs a cell header conversion operation needed for an ATM cell switching and a cell routing operation based on a VPI/VCI(Virtual Path Identifier/Virtual Circuit Identifier) address to output the performed result to a multiplexer(102). The ATM cell bus interface unit(101) receives a cell signal outputted from the multiplexer(102), and outputs the received cell signal to the ATM cell bus. The multiplexer(102) receives the ATM cell signal outputted from the ATM cell bus interface unit(101) to multiplex the received ATM cell signal, and outputs the multiplexed ATM cell signal to the first ADSL-C transmitting/receiving unit(103) and the first ADSL-R transmitting/receiving unit(104). The multiplexer(102) receives the ATM cell signal outputted from the first ADSL-C transmitting/receiving unit(103) and the first ADSL-R transmitting/receiving unit(104) to demultiplex the receive ATM cell signal, and outputs the demultiplexed ATM cell signal to the ATM cell bus interface unit(101). The first ADSL-C transmitting/receiving unit(103) receives a high-speed ATM cell bus outputted from the multiplexer(102), and converts the ATM cell signal into an ADSL frame signal to output the converted ADSL frame signal to the first line driver(105). The first ADSL-C transmitting/receiving unit(103) receives a low-speed analog ADSL signal outputted from the first line driver(105), and converts the received signal into the ATM cell signal to output the converted ATM cell signal to the multiplexer(102).

Title: 수문의 개폐장치
Filed: 1999-04-08
Abstract: 본 발명은 수문에 관한 것이다. 
     종래의 수문은 단순히 수압에 의하여 열리고 닫히는 수문이 있었으나 완전히 개문되는 수문은 없었던 것이 현실이다. 
     이러한 결점을 해소하기 위하여 본발명의 수문은 수문의 내부에 전자석 또는 자석을 구성시켜주어 수문을 열고자 할 때에 전자석과 연결된 전기를 차단시켜 수문을 개문시켜줄수가 있도록된 방식의 수문에 관한 발명인 것이다. 
     수문의 작동이 필요하면 이동식 발전기 또는 전기의 힘을 이용하여 개폐 시킬수가 있을 뿐만 아니라 최악의 조건하에서는 인위적인 조절에 의해서 개문시킬수가 있도록 된 수문인 것이다 
     종래의 유압식 수문[실용신안등록제107651호]과 같은 유압 피스톤식 수문은 홍수시에 상류에서 흘러 내려오는 모래 자갈과 같은 물질에 의하여 수문을 지탱하여 주는 피스톤이 망가지기 때문에 수문의 수명을 단축시켯던 것이며 또한 홍수시에 수문 하단부에서 발생하는 버불 현상에 의하여 모래 자갈등이 수문의 하단부로 밀려 들어갈수 밖에 없는 구조로 인하여 수문이 열릴때에 수문 하단부로 밀려 들어간 모래 자갈의 지랫대 현상에 의한 수문의 뒤틀림 작용으로 인하여 수문의 본래 기능을 상실하게 되는 것이다. 
     또한 고무판재로된 고무댐[보]의 경우[실용신안 등록제56240호]와 같이 물을 막고 있는 것이 고무로된 재료 이다보니 상류에서 흘러 내려오는 모래 자갈과 같은 것들이 고무판재에 충격을 가할수밖에 없다보니 제품의 수명이 단축 될 수밖에 없었던 것이다. 
     그러나 본 발명의 수문은 이러한 결점들을 해결하고자 수문의 본체는 금속 또는 프라스틱 재료로 구성시켯으며 수문의 개폐는 홍수시에 자동으로 감지되는 감지쎈서가 홍수를 감지하게 되면 전자석과 연결된 전기의 회로를 자동적으로 차단시켜버리기 때문에 자동적으로 열리게 되는 것이다 
     또한 전기적 동력이 차단 되었을때에는 인위적으로도 수문을 개폐를 하여 줄수 있는 수동 개폐장치는 공지의 기술이기 때문에 상술하는 것을 생략 하기로 한다. 
     수문을 닫고자 할 때에는 전기자석과 연결된 전기를 통과 시켜주게 되면 전자석의 힘에 의하여 자동적으로 닫히게 되는 것이다. 
     특히 평소에는 일반자석의 힘에 의하여 계획된 저장수위가 보장되는 폐문상태를 유지하다가 홍수시에는 가압되는 수압의 힘이 자석의 힘을 능가하기 때문에 자동적으로 수문이 열리게 되는 것이다.

Abstract: PURPOSE: A water turbine with high efficiency is provided to extract the super low head of water power in an overflow shape. CONSTITUTION: A water turbine(1) with high efficiency comprises two discs(2), many blades(3) and a rotating shaft(4). The blades are in an airfoil shape. When water passes through discs, the water turbine is rotated by the dynamic lift of the blades and rotated in one direction even though water direction is changed in a symmetrical shape with the rotating shaft. In case of shallow water, the diameter of the disc is increased and the length of the blade is reduced for high water power. In case of deep water, many water turbines are coupled in a line according to needed power. Thus, the water turbine is efficiently used in a river with no head or little head without air pollution.

Abstract: PURPOSE: A method for performing handover to a channel having a small interference of a DECT(Digital Enhanced Cordless Telephone) system is provided to make a base station previously confirm interference probability of a communication channel handover-requested from a mobile terminal, and to make the base station reject a handover request to perform handover with a new communication channel having a small interference. CONSTITUTION: A base station controller receives a handover request signal 'BHO.REQ(Bearer Hand Over. Request)'(S310). A base station MAC(Medium Access Control) directs the base station controller to reconfirm a wireless environment of a communication channel(S320). The base station controller confirms and records RSSI(Receive Signal Strength Indicator) values relating to all frequency channels of a slot including the communication channel(S330). The base station controller compares the RSSI values with a threshold value of the base station MAC(S340). If the RSSI values are bigger than the threshold value, the base station MAC performs a reject decision relating to the 'BHO.REQ' in the designated communication channel(S350). The base station MAC applies the reject decision to the base station controller as a 'BEARER.RES' signal(S360). The base station MAC transmits the reject decision to a mobile terminal as an 'MT_RELEASE' signal(S370). The base station MAC feeds back to the first step 'S310', without standing by an answer from the mobile terminal.

Abstract: PURPOSE: A mobile telephone for adjusting the calling sound automatically and an adjusting method thereof are provided to use the mobile telephone effectively according to circumstances by adjusting the calling sound of the mobile telephone in response to ambient noise. CONSTITUTION: A mike signal input terminal(10) receives the ambient noise of the mobile telephone through a mike, and applies the analog signal of the ambient noise to an amplifier(20). The amplifier(20) amplifies the analog signal from the mike signal input terminal(10) and receives a battery voltage signal, and then applies the analog signal and the battery voltage signal to a House Keeping Analog Digital Converter(H.K.ADC,30). The H.K.ADC(30) makes the level of the analog signal into data, and normalizes the data level as a digital signal to output to an MSM(Mobile Station Modem) chip(40). The MSM chip(40) inputs the level of the digital signal from the H.K.ADC(30) into an inner processor, changes the corresponding information into appropriate level of digital signal in response to the inputted value, and outputs the appropriate level of digital signal to a buzzer(50). The buzzer(50) adjusts the calling sound of the mobile telephone in response to the digital signal from the MSM chip(40), and generates the calling sound.

Abstract: PURPOSE: A nozzle core is to process a supplied yarn by an introduced compression fluid and is provided rotatably. Preferably, there is provided drive means for rotating the nozzle core. Preferably, a housing is provided to the nozzle core and is rotated integrally with the nozzle core. CONSTITUTION: Nylon 6 FDY70D-24F is used as each of the core yarn C1 and the entanglement yarn El, and is subjected to a compression fluid process with the use of the fluid processing apparatus 1 shown in figure 1 under the following conditions: Yarn speed: 400 m/min; Over feed of core yarn C1: +35%; One rotation of housing 11: 30 seconds. As a result, nozzle washing has been conventionally carried out at a rate of one time per 1 to 1.5 days; however, the replacement of the compression fluid processing nozzle may be carried out at a rate of one time per 4 to 5 days. Namely, it is possible to delay a washing period three to four times as much as the conventional case. Therefore, it is possible to greatly improve productivity as compared with the conventional case. Further, a process stability and yarn quality are unchanged, and a uniform bulky yarn can be obtained.
