  • Patent number: 9318724
    Abstract: Methods for protecting circuit device materials, optoelectronic devices, and caps using a reflowable getter are described. The methods, devices and caps provide advantages because they enable modification of the shape and activity of the getter after sealing of the device. Some embodiments of the invention provide a solid composition comprising a reactive material and a phase changing material. The combination of the reactive material and phase changing material is placed in the cavity of an electronic device. After sealing the device by conventional means (epoxy seal for example), the device is subjected to thermal or electromagnetic energy so that the phase changing material becomes liquid, and consequently: exposes the reactive material to the atmosphere of the cavity, distributes the getter more equally within the cavity, and provides enhanced protection of sensitive parts of the device by flowing onto and covering these parts, with a thin layer of material.

  • Patent number: 7691288
    Abstract: The invention is directed to a process for making screen-printable getter composition comprising: (a) glass frit; and (b) pre-hydrated desiccant material; dispersed in (c) organic medium. The present invention further relates to a getter composition utilizing low-softening temperature glasses comprising, based on weight %, 1-50% SiO2, 0-80% B2O3, 0-90% Bi2O3, 0-90% PbO, 0-90% P2O5, 0-60% Li2O, 0-30% Al2O3, 0-10% K2O, 0-10% Na2O, and 0-30% MO where M is selected from Ba, Sr, Ca, Zn, Cu, Mg and mixtures thereof. The glasses described herein may contain several other oxide constituents that can substitute glass network-forming elements or modify glass structure. The desiccant material is pre-hydrated to reach its saturation level of moisture absorption. The process of pre-hydration can be done by exposing the desiccant in a normal temperature/humidity environment of for example, 25° C. and 50-60% RH. For 24 to 48 hours or up to the time when weight gain (due to moisture absorption) stops increasing.

  • Publication number: 20100019651
    Abstract: The invention relates to a low-pressure mercury vapor discharge lamp provided with a discharge vessel (10; 210; 310) which encloses a discharge space (11; 211; 311) comprising a filling of mercury and a rare gas in a gastight manner. The discharge vessel (10; 210; 310) further comprises an amalgam (63; 263; 363) which communicates with the discharge space (11; 211; 311). The lamp has discharge means (41a, 41b; 234; 341a, 341b) for maintaining an electric discharge in the discharge vessel (10; 210). The amalgam (63; 263; 363) comprises a bismuth-tin-indium compound having a bismuth (Bi) content in the range between 30<Bi<70 wt. %, a tin (Sn) content in the range between 25<Sn<67 wt. %, and an indium (In) content in the range between 3<In<5 wt. %. The lamp according to the invention can be dimmed in a more controller manner.
