Abstract:
An object of the present invention is to provide a non-evaporating getter which can maintain the adsorbability for the residual gases, and in addition, can secure sufficient characteristics particularly even when it experiences a high-temperature and low-vacuum condition in the fabrication process of a display unit. A non-evaporating getter of the present invention is characterized in that it comprises a substrate having no function as a getter and a polycrystalline film arranged on the substrate which film contains Ti as the main component and has a host of voids in the interior thereof. The fabrication of a non-evaporating getter is made possible by forming a polycrystalline film containing Ti as the main component on the concavo-convex surface of the substrate which substrate has concavities and convexities on a surface thereof and has no function as a getter.
Abstract:
A vacuum device is provided with a getter device. The getter device comprises a deflector. The deflector is provided with raised and/or depressed portions, such as ribs or undulations in the direction of diffusion of the getter material.
Abstract:
A vacuum tube is provided with a line-shaped getter, which comprises a holder (2) with a longitudinal axis, which holder (2) contains a getter material (3) over at least a part of its length, said getter being provided with clamping means to clamp the holder (2). The vacuum tube comprises aligning means for exerting a torque about the longitudinal axis of the holder (2), said torque being as small as possible for a preferred orientation of the holder (2) relative to the clamping means. The clamping means preferably comprise two leaf springs (7, 7'), which are bent so as to be S-shaped and which are provided with apertures (9, 9', 9'') at locations where the leaf springs (7, 7') intersect, for passing the holder (2), and a member (6; 19) is provided on the holder (2) in a clamping manner and the clamping means are provided with an orientation surface (17, 17'; 18, 18'), which extends radially relative to the longitudinal axis of the holder (2). In this manner, during the activation of the getter, displacements of the holder (2) in a direction transverse to the longitudinal axis are precluded. Both constructions can be used independently and cause the position of the holder (2) to be more accurately defined relative to the other elements of the vacuum tube.
Abstract:
A display tube has a getter which is clamped in an aperture of the screening cap. The getter and the screening cap may be of a simple construction and the getter can be replaced in a simple manner so that the display tube can be easily repaired. The getter is supported by the cone and the inner wall of the screening cap.
Abstract:
A gas probe starter (12) for an electrodeless HID lamp (10) includes a getter for removing gaseous impurities from the fill contained in the starting chamber (34) of the gas probe starter (12). In a preferred embodiment, a metal foil (50) having active getter material disposed on the surfaces thereof in the form of a sintered powder is inserted at an optimum location in the starting chamber (34) which depends on the optimum operating temperature of the particular getter material.
Abstract:
A method for the manufacture of a non-evaporable getter device having an electrophoretically deposited electrically insulated heater and support lead wires. To avoid the production of loose particles or short circuits each support lead wire is encircled by a hollow insulating cylinder whose surfaces are partially covered by the electrophoretically deposited heater insulation thus providing a reinforced insulated heater getter device.
