Title: Apparatus for output automatic compensation of multi-channel digital transceiver
Inventor: YOO GYEONG BONG
IPC: H04B7/155
Filed: 2002-12-18
Abstract: PURPOSE: A device for automatically compensating an output of a multi-channel digital transceiver is provided to time-divide an output local frequency of a PLL module, and to convert a down-converted IF in a frequency down-converter, thereby automatically compensating a transmission output with a DC voltage passing through a channel filter. CONSTITUTION: A frequency down-converter(207) converts a multi-channel frequency extracted from a directional coupler(206) into a certain IF. A PLL module(212) time-divides a local frequency controlled according to a multi-channel FA(Frequency Allocation), and outputs the divided local frequency to the frequency down-converter(207). Channel filter/power detector(208) passes a specific frequency band only, and converts the passed frequency band output into a DC value. A controller(211) controls transmission output attenuation degrees of an attenuator(204), and controls a gain of a channel synthesizer/CFR(Crest Factor Reduction) portion(201) by using a DC voltage of the passed frequency.

Abstract: PURPOSE: A system and a method for providing origination area information service of an originated call of a mobile phone are provided to effectively process of a call of a mobile subscriber by extracting area information of an originated call. CONSTITUTION: When an SCP(Service Control Point) receives a call triggered from an SSP(Service Switching Point)(301), it analyzes the call(302), recognize whether the call is for a service requiring origination information, and analyzes the received origination number(303). If the origination number indicates a mobile phone, the SCP requests an SSP(Service Switching Point) connect a channel with an AIN-IP(Advanced Intelligent Network Intelligent Peripheral)(304). When a signal requesting a service is received, the AIN-IP sends a prepared announcement to a user and requests inputting of voice(305), receives and recognizes subscriber's voice or a phone code of an origination area(306), and then, extracts information on an origination prefix(307). The AIN-IP transfers the extracted origination information to the SCP(308). The SCP searches an actual destination phone number(309). The SSP pages a destination provider and connects a channel between a terminal of an origination subscriber and the destination provider(310).

Title: Semi-solid concentration processing of metallic alloys
IPC: B22D17/00
Filed: 2000-07-26
Abstract: A metallic alloy having a semi-solid range between the liquidus temperature and the solidus temperature of the metallic alloy is processed by cooling the metallic alloy from an initial metallic alloy elevated temperature to a semi-solid temperature of less than the liquidus temperature and more than the solidus temperature, and maintaining the metallic alloy at the semi-solid temperature for a sufficient time to produce a semi-solid structure in the metallic alloy of a globular solid phase dispersed in a liquid phase. The cooling may be accomplished by providing a crucible at a crucible initial temperature below the solidus temperature, pouring the metallic alloy into the crucible, and allowing the metallic alloy and the crucible to reach a thermal equilibrium between the liquidus temperature and the solidus temperature of the metallic alloy. The method further includes removing at least some, but not all, of the liquid phase present in the semi-solid structure of the metallic alloy to form a solid-enriched semi-solid structure of the metallic alloy, and forming the metallic alloy having the solid-enriched semi-solid structure into a shape.

Abstract: 본 발명은 플로트 유리의 제조중에 유리 용융 탱크로부터 조절가능한 공급 채널을 통해 스파우트 립에 공급되고 그 표면상에서 플로트 조의 주석 표면으로 안내되는 유리 용융물을 스파우트 립을 지나 공급하기 위한 장치에 관한 것이다.  본 발명에 따르면, 유리 용융물에 접하게 되는 적어도 스파우트 립의 표면이 내화성의 비희유 금속 층으로 덮이면, 스파우트 립의 서비스 수명이 상당히 증가된다.
