  • Patent number: 6016668
    Abstract: A method for dissolving a hardened glass solder, a method for separating components joined by a glass solder, a method for disassembling a fuel cell, and an apparatus for disassembling a fuel cell, include heating the hardened glass solder in a melt of a hydroxide. As a result, components which had been joined through the use of the hardened glass solder are able to be reused or subjected to a recycling process.
    Type: Grant

  • Patent number: 4362766
    Abstract: In the present invention a process is provided for depositing a protective passivating film of doped or undoped amorphous silicon on a body of semiconductor material. In the process a body of semiconductor material is disposed within a reaction vessel, a silicon-hydrogen gaseous compound is fed into the reaction vessel and decomposed by means of a glow discharge. The decomposition of the silicon-hydrogen gas mixture results in the deposition of amorphous silicon on the semiconductor body.
