  • Publication number: 20190301661
    Abstract: The proposed vacuum jacketed tube may deliver the high/low temperature fluid with less temperature-transfer, especially may delivery high/low temperature fluid through a flexible structure. The vacuum jacketed tube includes a tubular structure surrounding a pipe wherein the fluid is delivered therethrough. Also, the space between the tubular structure and the pipe may be vacuumed. Therefore, the heat transferred into and/or away the fluid may be minimized, especially if the tubular structure and the pipe is separated by at least one thermal insulator or is separated mutually. Moreover, the vacuum jacketed tube may be mechanically connected to the source/destination of the delivered fluid, even other vacuum jacketed tube, through the bellows and/or the rotary joint. Besides, the pipe may be surrounded by a Teflon bellows and the tubular structure may be surrounded by a steel bellows, so as to further reduce the heat transferred into/away the fluid delivered inside the pipe.

  • Patent number: 9805913
    Abstract: A process control method is provided for ion implantation methods and apparatuses, to produce a high dosage area on a substrate such as may compensate for noted non-uniformities. In an ion implantation tool, separately controllable electrodes are provided as multiple sets of opposed electrodes disposed outside an ion beam. Beam blockers are positionable into the ion beam. Both the electrodes and beam blockers are controllable to reduce the area of the ion beam that is incident upon a substrate. The electrodes and beam blockers also change the position of the reduced-area ion beam incident upon the surface. The speed at which the substrate scans past the ion beam may be dynamically changed during the implantation process to produce various dosage concentrations in the substrate.
