  • Patent number: 7845548
    Abstract: The present invention is directed to a lamination method. The lamination method includes making the interior of a process chamber a vacuum, the process chamber including a first and a second metal sheet, supplying the first and the second metal sheets, injecting a bonding material between the first and the second metal sheets supplied, bonding the first and the second metal sheets with each other, and heating the bonded metal sheets. The first metal sheet is a superconductive tape, and the second metal sheet is stabilization metal tape.

  • Publication number: 20090107395
    Abstract: Disclosed herein is a deposition apparatus with a guide roller for a long superconducting tape. The deposition apparatus has a supply reel which is provided in a vacuum chamber and rotated to supply the tape, a feed and deposition unit which is spaced apart from the supply reel and vacuum deposits a superconducting layer on the tape while feeding the tape, and a collection reel which is spaced apart from the feed and deposition unit and is rotated to collect the vacuum-deposited tape.

  • Publication number: 20090110952
    Abstract: Disclosed herein is a gradient thin film, formed on a substrate by simultaneously depositing different materials on the substrate using a plurality of thin film deposition apparatuses provided in a vacuum chamber, wherein the gradient thin film is formed such that the composition thereof is continuously changed depending on the thickness thereof by deposition control plates provided in the path through which the different materials move to the substrate. The gradient thin film is advantageous in that the thin film is formed by simultaneously depositing different materials using various deposition apparatuses, so that the composition thereof is continuously changed depending on the thickness thereof, with the result that the physical properties of a thin film are easily controlled and the number of deposition processes is decreased, and thus processing time and manufacturing costs are decreased, thereby improving economic efficiency.

  • Publication number: 20080067273
    Abstract: Disclosed is a long-tape deposition apparatus for depositing specific substance on superconductive tape. The apparatus includes a drum having a helically-shaped guide groove formed on the outer surface thereof and a strip of tape wound along the guide groove and disposed in a vacuum chamber, a deposition source disposed to be distanced from the drum, a supply reel and a retreat reel disposed at respective sides of a shaft of the drum for supply and retreat of the tape, respectively, in which when the drum rotates, specific substance from the deposition source is deposited on the surface of the tape and at the same time the tape is continuously supplied and retreated by the supply reel and the retreat reel, and a slip-roller installed to extend along longitudinal direction of the drum, to be near the circumferential surface of the drum and to protrude from the outer surface of the drum, the slip-roller which rotates along moving direction of the tape enabling the tape to slip over the guide groove of the drum.

  • Publication number: 20070057017
    Abstract: The present invention is directed to a lamination apparatus and a lamination method using the same. The lamination apparatus includes a process chamber and a pump connected with one side of the process chamber for making the interior of the process chamber a vacuum. Inside the process chamber, a first and a second supply unit, an injection unit, and a bonding unit are provided. The first and the second supply units supply a first and a second metal sheet, respectively. The injection unit injects a bonding material between the first and the second metal sheets supplied, and the bonding unit bonds the first and the second metal sheets with each other. According to the present invention, a bonding force of the bonding material may be enhanced and various kinds of bonding materials may be used.
