Abstract: PURPOSE: A semi-permanent virtual connection control method by a server is to provide various services by minimizing a change to a software in a terminal for a multimedia service communication between call originating subscriber and a destination subscriber. CONSTITUTION: In a standby state(300), when a service request is received from a semi-permanent virtual connection subscriber(301), an asynchronous transfer terminal requests a service from a server through a switching system(302), and the server analyzes a profile of a registration service by its management table(303) to determined whether the service is identical to registered information(304). If the service is identical to the registered information, the server transmits a service available and resource reservation state to the terminal(305). The switching system transmits and receives a service according to the registered information(306), when the switching system receives a service completion request from the subscriber or from the server(307), it performs a release procedure(308). If the service is not identical to the registered information, the server transmits service not-available and its reason to the terminal, and determines whether the subscriber is a service registered information change available subscriber(310). If the subscriber is a service registered information change available subscriber, the server determines whether a registered information negotiation is possible(311). If the registered information negotiation is available, the server receives a changed information from the subscriber(312), receives negotiated information, processes it and is transited to a standby state(315). If the subscriber is not the service registered information change available subscriber or the registered information negotiation is not possible, it ends the process(316).

CONSTITUTION: The apparatus comprises a plurality of culture containers a cover having water inlet holes(4') formed a depressed central part(4) and a connecting groove around the lower face and a container(3) with a bottom face having a plurality of drainage holes, and a plurality of holding boxes composed of a bottom face(8) composed of latticed frames(9) and a catch rise formed bottom edge for holding and fixing the culture containers. The cover and the container are united into one body, and the boxes holding the culture containers are piled in layers in a fixed height and area.

Abstract: 본 발명은 GSM 900MHz, DCS 1800MHz, 및 DCS 1900MHz 대역과 같은 다중 대역에서 각 대역에 대한 혼합기의 필요성을 제거함에 의해 통신 장치(100)가 동작 가능한 방법 및 장치에 대한 것이다.  예를 들면, 2중 대역 GSM/DCS 1800 무선 전화기에 있어서, GSM 및 DCS 대역 모두에 대한 국부 발진기(LO) 삽입 주파수는 조합 필터(222, 246)의 사용을 통해 혼합기(234)로 제공된다.  그러므로, 혼합기 입력으로 이중화(duplexing) 및 정합(matching) 요구는 단순화되고 신호 손실을 최소화된다.  GSM RX/LO 조합 필터 및 DCS RX/LO 조합 필터의 공통 출력 포트는 혼합기의 입력으로 이중화된다.  또한, 혼합기의 입력 임피던스 정합은 IF 주파수에서 RF 트랩을 제공하는 외에, 각 대역내에서의 수신된 신호에 대한 임피던스를 정합시키도록 설계된다.  혼합기의 출력에서의 정합은 IF 필터의 주파수를 정합시키도록 설계되며, RF 입력 주파수에 저 임피던스를 제공한다.  최종적으로, 3중-대역 무선 전화기가 또한 설명된다.
