    摘要: Silver flake and lead borate glass frit are suspended in a liquid organic vehicle of resin and solvent. The silver flakes are present in two different size ranges. The plate is applied between the silicon die and the substrate and is oven fired to provide a bond that accommodates the different coefficients of thermal expansion of the silicon and ceramic substrate. The smaller silver particles improve the sintering of the silver and glass and thereby increase the bond strength while the larger silver particles minimize undersirable shrinkage and cracking of the resultant bond. Silver oxide particles or a special solvent mixture are also used in the paste.

    摘要: A silver glass paste consists of 60-75% silver flake having a tap density greater than 2.8 gm/cc and less than 5.0 gm/cc. The silver flake has a poly-modal flake size distribution. The paste further consists of 12-20% glass frit, 0.5-2% of a suitable organic resin and 8-20% of a suitable organic solvent. The resin may be acrylic and the organic solvent may be an ester alcohol or an ester alcohol mixed with a glycol ether or glycol ether ester.

    摘要: A rectangular frame contains a plurality of upwardly opening trays each having a heat absorber element with a plurality of upstanding vanes. A lens associated with each tray concentrates incident solar radiation on the vanes to preferentially heat a portion of the liquid filling the tray to a relatively high temperature at which vaporization is more efficiently accomplished than in prior solar stills. The evaporated liquid is condensed on an overlying surface and is collected for later use. The system may be used in distilling water and in solar refrigeration.
