    • A cryovessel, in which liquid helium contained in a helium container is maintained at a constant pressure, temperature and volume by using a Gifford-McMahon cryocooler, and control method for such a cryovessel is provided. The cryovessel includes a vacuum container for heat insulation; a helium container disposed in an inner lower portion of the vacuum container in such a manner that the helium container is spaced apart from the vacuum container, the helium container accommodating a superconductive magnet dipped into a liquid helium so as to receive power through a double cable; a GM cryocooler having upper and lower cooling portions accommodated into the vacuum container and a condensing portion connected to the helium container, the GM cryocooler receiving a re-condensed helium from a condenser; a conduction cooling unit for interconnecting the upper cooling portion of the GM cryocooler and the double cable connected to the superconductive magnet, the conduction cooling unit conductively cooling a heat transferred through the double cable; a controller connected, through pipes, to the condenser, heater for heating the helium container, the helium container and the vacuum container, and which controls a pressure gauge for gauging pressure of each container; and a power supply for supplying power to each component. Thus-configured cryovessel is compact in size, inexpensive to manufacture, and capable of minimizing loss of helium. Super cooling is prevented through the use of heater and pressure, liquid level and temperature of the helium container can be maintained constant, to thereby operate the superconductive magnet in a stable manner.
    • 通过使用Gifford-McMahon制冷机将氦容器中所含的液氦维持在恒定的压力,温度和体积,并提供这种低血管的控制方法的冷冻血管。 冷冻血管包括一个用于隔热的真空容器; 氦容器,其设置在真空容器的内下部,使得氦容器与真空容器间隔开,氦容器容纳浸入液氦中的超导磁体,以便通过双电缆接收电力 ; 具有容纳在真空容器中的上下冷却部分和连接到氦容器的冷凝部分的GM制冷机,GM冷冻机从冷凝器接收再凝结的氦; 导电冷却单元,用于将GM制冷器的上部冷却部与连接于超导磁体的双电缆互连,导电冷却单元导通地冷却通过双电缆传递的热; 控制器通过管道连接到冷凝器,用于加热氦容器,氦容器和真空容器的加热器,并且控制用于测量每个容器的压力的压力计; 以及用于向每个部件供电的电源。 如此配置的冷冻血管尺寸紧凑,制造成本低,并且能够最小化氦的损失。 通过使用加热器和压力来防止超冷却,可以使氦容器的液位和温度保持恒定,从而以稳定的方式操作超导磁体。

    • A noxious insect decoy is provided to be disposed in a predetermined space, and to induce noxious insects to be killed naturally by inducing noxious insects to enter an inducing hole disposed between partitions. A noxious insect decoy includes a case body and a cover. The case body has a predetermined internal space, and the cover is detachably coupled to the case body by external force. The cover consists of another cover that includes an inducing hole for a noxious insect(12) that is directly coupled to the case body, and is coupled to the cover(10) to have an internal space for easily inducing noxious insects. The covers(10) are coupled by being engaged with each other by a coupling shaft and a coupling protrusion. Chemicals for inducing the noxious insects are received into the case body.
