Description

本发明涉及一种装在电子管内的圆环形消气装置。
圆环形消气装置在技术上是人所熟知的,例如美国专利NO.3151736、3381805、和3385420中就公开过这种装置。为了从这种装置获得消气金属的高产出率,一般的做法是扩大或加宽环形通道,美国专利NO.3719433和4642516公开过这种“宽通道”消气装置。
但是,即使是这种类型的装置也不可能保证大量地蒸发出消气金属蒸气而并不出现可放出消气金属的消气材料从其容器中脱落、甚至引起消气剂容器壁熔化的危险。
因此,本发明的目的是提供一种改进的宽通道消气装置,这种装置不存在现有技术中同样形状的消气装置的一个或多个缺点。
本发明的另一目的是提供一种具有高的消气金属产出率的宽通道消气装置。
本发明的再一个目的是提供一种不出现消气剂容器壁熔化的宽通道消气装置。
本发明的又一个目的是提供一种可放出消气金属蒸气的消气材料不会从容器中脱落的宽通道消气装置。
通过下面对本发明的详细说明和附图,本专业的技术人员将能更清楚地了解本发明的上述的和其他的目的和优点。附图中:
图1是本发明消气装置的第一最佳实施例的顶视平面图;
图2是沿图1的2-2′线的横截面图;
图3是本发明消气装置的第二最佳实施例的顶视平面图;
图4是沿图3的3-3′线的横截面图;
图5是本发明消气装置的闪蒸特征(钡蒸发特性)与现有技术消气装置的闪蒸特性的对比曲线图。
下面参见附图,特别是图1和2,图中同一零件标以同一标号,图中示出了适合于装在电子管内的宽通道圆环形的气化消气装置100的第一最佳实施例。消气装置100包含一个最好用不锈钢制的容器102,用来支持可放出消气金属蒸气的消气材料104,容器102有竖直外壁106、竖直内壁108和连接外壁106与内壁108的底部110。底部110设有防止消气材料从容器中脱落的机构112。在这第一最佳实施例中,上述机构112是环形槽114的形式,它与底壁做成一整体,并穿入由外壁106与内壁108构成的空间。环形槽114的横截面通常为灯泡状,它在向下邻近底壁110处变窄。
将消气材料104压入由上述内壁、外壁和底壁构成的空间,并由容器102支持着。消气材料104有上表面116和置于该表面上的保温机构118、118′、118″、118″,当位于电子管外的线圈产生的射频(RF)场所感应的电流加热消气装置时,上述保温机构可减缓热量通过消气材料向周围散发。保温机构最好包含四个等间距的径向槽,这些槽压入上述消气材料的上表面,并且至少部分地穿入由上述内壁、外壁和底壁构成的空间,它们的长度通常大于宽度。
下面参看图3和4,图中示出了气化消气装置200的第二最佳实施例。其容器202具有由底壁208连接在一起的外壁204和内壁206,容器202支承着可放出消气金属蒸气的消气材料210,消气材料210有上表面212和多个保温机构214、214′、214″、214″,保温机构最好具有四个等间距的径向槽,这些槽被压入上述消气材料的上表面中,并且至少部分地穿入由上述内壁、外壁和底壁构成的空间,它们的长度一般大于宽度。
底壁208设有防止消气材料210脱落的机构216,这种机构的形式是多个穿通底壁208并暴露出消气材料210的下表面的孔218。这就可防止材料210与底壁208之间形成过高的压力。
例1
这个例子说明现有技术的消气装置的特性。制成了30个消气剂容器,其外壁直径15mm、内壁直径4mm,其底壁没有环形槽。容器中填有1000mg含50%BaAl4和50%Ni(重量百分数)的粉末混合物,其上表面不设置保温机构。按照美国国家标准ASTM F 111-72使消气剂闪蒸,以便测定钡的产出率曲线。花的总时间为35秒。得到的产出率曲线示于图5中曲线1。消气剂容器开始熔化的起始时间用线A表示。
例2
本例也说明现有技术的消气装置的特性。制成了30个消气装置,并按例1那样严格闪蒸,但其容器底壁设有如美国专利NO.4642516所述的槽。得到的产出率曲线示为图5中曲线2。消气剂容器开始熔化的起始时间用线B表示。
例3
本例说明本发明消气装置的特性。按例2制成30个消气装置,但其消气剂粉末混合物的上表面设置有如图1和2所示的保温机构。得到的产出率曲线示为图5的曲线3,消气剂容器开始熔化的起始时间用C线表示。
例4
本例也是说明本发明的,按例3制成30个消气装置,但底壁上的槽用图3和4所示的孔代替。结果发现其曲线与图5的曲线3和线C一样。
从图5可以看出,在现有技术的例1和例2的消气装置中,当消气金属钡的产出率只稍稍超过180mg,即等于消气装置中含钡量(250mg)的72%时,消气剂容器便开始熔化。
而本发明消气装置在消气剂容器开始熔化前能产出约230-240mg的钡,约等于消气装置含钡量的92~96%。
在本说明书和权利要求书中所用的“可放出消气金属蒸气的消气材料”一词的意思既包括释放出消气金属蒸气前的材料也包括释放出消气金属蒸气后的材料。这个词既可理解为与消气装置一起出售的消气材料,也可理解为在工作管子中的消气材料,后者是消气金属已从消气材料中蒸发出并在管子内表面形成薄膜的材料。
虽然上面已参考一些最佳实施例较为详细地说明本发明,这些实施例告知本专业的技术人员如何最好地实践本发明,但是,在不背离本发明的精神和范围的原则下,其它的改型也是可以应用的。
