  • Film transfer method
    Patent number: 6666943
    Abstract: A device is formed by transferring a film onto a substrate when the film requires but the substrate is not adapted to a high temperature heat treatment process. The film having layers and formed on a first substrate having layers is transferred onto a second substrate having layers. The method of transferring the film comprises a first step of forming a lift-off layer and the film to be transferred on the first substrate, a second step of bonding the film to be transferred to the second substrate and a third step of separating the film to be transferred from the first substrate by etching the lift-off layer and transferring it onto the second substrate.

  • Signal outputting apparatus and image forming apparatus
    Publication number: 20030053089
    Abstract: A signal output apparatus comprises a vibration applying unit that contacts with and applies a vibration to a sheet, and a detection unit that outputs a signal by the vibration. An apparatus for determining a type of a sheet comprises a vibration applying unit that contacts with and applies a vibration to a sheet, and a detection unit that outputs a signal by the vibration, wherein a type of the sheet is determined on the basis of the signal from said detection unit. An image forming apparatus comprises a vibration applying unit that contacts with and applies a vibration to a sheet, and a detection unit that outputs a signal by the vibration.
