Document Type and Number:
Japanese Patent JP2623353
Kind Code:
B2
Abstract:
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 which delays the transfer of heat in a radial direction through the getter vapor releasing material. When the getter device is heated by currents induced from a radio frequency field created by a coil positioned outside the tube, opposite the getter device, high yields of getter metal are released in a short time without detachment of the getter material residues from the container.
