  • LARGE AREA DEPOSITION IN HIGH VACUUM WITH HIGH THICKNESS UNIFORMITY
    Publication number: 20150114566
    Abstract: The invention relates to an effusing source for film deposition made of a reservoir comprising one hole characterized by the fact that the hole diameter is less than one order of magnitude than the mean free path of the molecules determined by the pressure and its thickness is at least one order of magnitude smaller than the diameter. Preferably the source has several holes.

  • Process and apparatus for spot welding with a laser beam
    Patent number: 8304687
    Abstract: The invention relates to a laser spot welding process for executing a spot weld in two successive steps, namely a first step of preparing the surface state of the material to be welded and a second step of welding as such. The luminous energy (BR) reflected by the weld region of the material is measured in real time during the first step and then processed by a controller circuit (37) connected to a control circuit (30) of the laser source (31). In this way, the characteristics (LM) of the laser beam are adjusted in real time as a function of the measurements effected to allow effective control of the quality of the weld obtained, and in particular of its dimensions. The invention also relates to a welding device for implementing this process.
