IMPROVED HIGH-CAPACITY GETTER PUMP AND MANUFACTURE OF ITS BLADE BY SINTERING

摘要

FIELD: vacuum pumps. SUBSTANCE: getter pump has many porous sintered blades made of nonevaporating getter material and provided with first flat surface, second flat surface parallel to first one and spaced 0.5-5.0 mm from the former in thickness; blades are placed in casing and separated by empty space; abutting surfaces of adjacent blades are spaced 0.5-10 mm apart. EFFECT: improved design.
