摘要： PROBLEM TO BE SOLVED: To provide a radio communication system capable of reducing the stringency of the high-speed radio service in an area or near a boundary where both a high-speed radio base station and a low-speed radio base station provide service.SOLUTION: Two types of threshold values are set to parameters required for hand down control for every application type indicating service which a terminal receives. For a user, such as a user performing an HD image communication, who wants to continue the high-speed radio service with a high throughput, a hand down threshold value is set to be low to prevent that switching between high-speed radio service and low-speed radio service cannot be made frequently. For a best-effort user who does not need a sufficient throughput, on the other hand, the hand down threshold value is set to be high to control that switching between high-speed radio service and low-speed radio service can be made positively.
摘要翻译：要解决的问题：提供一种无线电通信系统，其能够降低高速无线电基站和低速无线基站两者的边界内的区域或附近的高速无线业务的严格性提供服务。
解决方案：两种类型的阈值被设置为终端接收的每种应用类型指示服务的切换控制所需的参数。对于希望以高吞吐量继续高速无线电业务的用户（例如执行高清图像通信的用户），将切换阈值设置为低以防止在高速无线电业务和低速无线电业务不能频繁发生。另一方面，对于不需要足够的吞吐量的尽力而为的用户，降低阈值被设置为高，以便可以积极地进行高速无线电业务和低速无线业务之间的切换。版权所有（C）2012，JPO＆INPIT

摘要： PURPOSE:To early uniformize a circulating water temperature to eliminate a chilled water layer, and to remove marine living things by providing an auxil iary system having an auxiliary circulating pump inside a saline water circulat ing system, and agitating, mixing the water in an outlet of the auxiliary system. CONSTITUTION:At the time of filling water before a plant is stopped, an auxiliary system inlet valve 121 and an auxiliary system outlet valve 120 are opened to fully fill sea water in an auxiliary system 116, and a small circulating cycle of the system 116-a sea water circulating system 108-the system 116 is formed. A flow velocity in the system 116 is enhanced by an auxiliary system circulating pump 117, circulating warm water is agitated to uniformize its temperature. The circulating water having a small temperature difference is supplied to the system 108 by mixing high temperature water at an auxiliary system outlet 118 with auxiliary system water raised at its temperature at each one cycle. Thus, stepwise temperature rise is intended to suppress a temperature layer formation. Accordingly, circulating water temperature can be made uniform, and existence of marine living thing can be suppressed.

摘要： PROBLEM TO BE SOLVED: To collect the latest safety information in a short time without generating congestion in a network when communication between a safety confirmation server on a center side for collecting the safety information from a portable radio terminal and radio base stations recovers after the communication between both of them becomes impossible during a disaster occurs.SOLUTION: When communication with a safety confirmation server 103 becomes impossible due to the occurrence of a disaster, each radio base station 101 autonomously collects safety information from a portable radio terminal 102 controlled by the own station. At a point of time when the communication with the safety confirmation server 103 recovers, each radio base station 101 consolidates the safety information which has been collected up to the time and collectively transmits the consolidated safety information to the safety confirmation server 103.
