초록

An evaporable getter device for mounting in an electron tube is provided which comprises a pan-shaped container having a vertical side wall formed around the perimeter of a disc shaped bottom wall and a pulverized getter metal vapor releasing material pressed into the space formed by said side wall and said bottom wall. There is also provided a first heat transfer retarding means which delays the transfer of heat in a circumferential direction through the getter metal vapor releasing material. There is also provided a second heat transfer retarding means...
