There is described a process for the vapor deposition of a scintillator phosphor composition with concomitant shadowing wherein the substrate to be processed is rotated through an arc relative to a vapor source of the scintillator phosphor composition whereby shadowing introduces voided gaps or interstices between columns as a result of the preferential components receiving more coating flux, particularly in the presence of oblique flux. 8 figs.

Process for manufacturing storage batteries and battery produced thereby

Patent - in OSTI.gov collection Sanekata, N. ; Hamada, O.

This invention relates to a process for manufacturing storage batteries and the batteries produced by such process. The process comprises the steps of inserting anode and cathode plates into a container; inverting the container and embedding the projecting lugs of the anode and cathode plates in a sealing agent disposed in concavities in a cover for the container; sealing the cover on the container; removing respective portions of the cover after the solidification of the sealing agent to present thereby a plurality of cavities, each of which exposes the lugs of corresponding anode plates and cathode plates of adjacent cellsmore »« less

Method of producing submicron size particles and product produced thereby

Patent Bourne, R.S. ; Eichman, C.C. ; Welbon, W.W.

Submicron size particles are produced by using a sputtering process to deposit particles into a liquid. The liquid is processed to recover the particles therefrom, and the particles have sizes in the range of twenty to two hundred Angstroms. Either metallic or non-metallic particles can be produced, and the metallic particles can be used in ''metallic inks.'' 4 figs.

Continuous process for fabricating solar cells and the product produced thereby

Patent - in OSTI.gov collection Deminet, C. ; Horne, W.E. ; Oettel, R.E.

The process comprises the following steps: (1) forming a glass sheet which defines a substrate layer for the solar cell product; (2) forming a diffusion barrier layer on at least one surface of the substrate; (3) forming a first electrically-conductive layer on the diffusion barrier, the first electrically-conductive layer being a first electrode in the solar cell product; (4) depositing small-grain polycrystalline silicon in a thin film, i.e., 10 to 100 micrometers, on the first electrode layer; (5) recrystallizing, typically by heating, the deposited polycrystalline silicon until it reforms into large-grain polycrystalline or single-crystal silicon; (6) forming a PN junctionmore »« less

Process for fabricating solar cells and the product produced thereby

Patent - in OSTI.gov collection Corwin, R.E. ; Riemer, D.E.

An electrically conductive, anti-reflective coating is formed on a base layer of prepared silicon in such a manner as to form a good ohmic contact therewith. If doped, the coating can serve as an impurity source during a following diffusion step, in which a p-n junction is formed in the silicon. Undoped coatings may be used when the p-n junction has previously been formed in the silicon. Thick film electrical contacts are then formed by screen printing on the top surface of the anti-reflective coating and then fired at high temperature, I.E. 500/sup 0/-1000/sup 0/ C.
