  • Patent number: 5945162
    Abstract: A method is disclosed for introducing into a chemical vapor deposition chamber precursors of elements to be deposited over a heated substrate. The method comprises the steps of maintaining one or more precursors in liquid form or in solution at a pressure higher than the pressure of the chamber; injecting periodically and under control in the deposition chamber precursor droplets each of the droplets having a controllable volume; volatizing the injected precursor droplets to produce evaporated precursors, and conveying toward the substrate the evaporated precursors at a temperature and pressure of the chamber, whereby the evaporated precursors react to produce the elements deposited onto the substrate.

  • Patent number: 5214926
    Abstract: Device for extracting heat from a hot source (7) and transferring it to an autonomous heat accumulator, which is portable, forming a cold source, this device having the special feature that the said accumulator is formed by an enclosure (1) containing ammonia under conditions such that at least a significant portion of the heat transferred to this accumulator causes the ammonia to pass from the solid state to the liquid state. The device is usable for the thermal control of protective equipment or of leakproof protective suits intended for work in a toxic atmosphere or at high temperature, or also in space.
