Title: Handover between wireless telecommunication networks/systems
IPC: H04W36/14
Filed: 2000-09-01
Abstract: A method and a wireless telecommunication system of performing network-assisted handover of calls between a serving network and another wireless network that employs communication protocols different from those of the serving network. A message is sent from a mobile station of a user to the serving wireless network, which includes an indication that the mobile station is capable of communicating with the neighboring wireless network. Information relating to the communication characteristics of the neighboring wireless network is also sent from the serving wireless network to the mobile station. Using the information relating to the communication characteristics of the neighboring wireless network, the mobile station receives radio signals from the neighboring wireless network. The quality of the radio signals between the mobile station and the neighboring wireless network is measured. The serving wireless network sends a message to the neighboring wireless network to request a handover of the communication transaction when the quality of the radio signals between the neighboring wireless network and the mobile station meets a predetermined minimum threshold. Then a handover of the communication transaction from the serving wireless network to the neighboring wireless network is executed after the neighboring wireless network has established a communication channel for the mobile station pursuant to the handover request.

Abstract: PURPOSE: A space-saving cathode ray tube is provided to realize a CRT having a depth that is less than that of a conventional CRT having an equivalent screen-size. CONSTITUTION: A cathode ray tube(510) includes an electron gun(512) directing electrons towards a faceplate(520) having an electrode(522) biased at screen potential. The electron beam is magnetically deflected to scan across the faceplate(520) to impinge upon phosphors(523) thereon to produce light depicting an image or information. A neck electrode(544) near the tube neck is biased at or below screen potential and a second electrode(546) between the neck electrode(544) and the faceplate(520) is biased at or the screen potential. As a result, the electrons are deflected over a greater total angle than is obtained from the magnetic deflection. A third electrode proximate the faceplate(520) is biased at or below screen potential to direct electrons towards the faceplate(520), thereby to increase the landing angle of the electrons thereon. A metal and ceramic support includes a resistive voltage divider to which ones of the electrodes connect.

Abstract: 자동차의 공조기 등에 사용되는 냉매 팽창밸브의 내구성 향상을 꾀한다. 
     10은 오리피스부재이며, 밸브 본체(30)의 오리피스(32a)가 밸브 본체(30)를 구성하는 알루미늄재보다 경도가 높은 예를 들면 스테인레스재로 구성되어 있다. 오리피스부재(10)는 대략 원통상으로 형성되어 있고, 일방의 개구의 단부(10a)는 오리피스(32a)를 형성하는 밸브 본체(30)의 접촉면과 평면 접촉하도록 평면 형상으로 형성되고, 타방의 개구의 단부는 밸브체(30)와 대항배치 되도록 여덟팔자 모양의 테이퍼 형상으로 형성되어 있다. 또한, 오리피스부재(10)의 외측부에는 나사부가 형성되고, 밸브 본체(30)의 오리피스(32a)에 형성된 나사부와 나사결합하여 오리피스(32a)에 고착되어 있다. 또한 이 고착을 견고히 하도록, 오리피스부재(10)와 오리피스(32a)와의 나사결합부에 접착제 예를 들면 록타이트를 도포하여 경화시켜도 된다. 밸브 본체(30)에 알루마이트 처리가 되어 있어도 오리피스부재(10)는 밸브 본체(30)와 평면 접촉하여 고착되므로, 밸브 본체(30) 상의 알루마이트 피막을 찢고, 부분적으로 알루마이트 피막을 파괴하는 일이 없다.
