  • Patent number: 8956501
    Abstract: A method and apparatus for replacement of damages display shield (typically glass) covering a display screen on a device, typically a mobile phone. Mobile phones have an electronic display protected by a glass shield. Between the glass and the display is often a plastic polarizing or other intermediary sheet. Removal of a damage glass can be accomplished by cutting thru the polarizer with a moving wire or blade. This separates the glass from the sensitive display and allows replacement of the glass without damaging the more expensive display.

  • Patent number: 8844602
    Abstract: Provides a method and a terminus processing tool whereby terminus processing for the purpose of connection to another optical fiber may be carried out simply. The terminus processing method entails cutting an optical fiber 20 composed of a glass fiber 21 and a coating 24; and with the optical fiber 20 positioned relative to a terminus processing tool that is disposed contacting the coating at the end surface of the optical fiber 20 and that has a protruded-into space for accommodating inward protrusion of the glass fiber 21, and with the cut end surface of the glass fiber 21 facing the protruded-into space, pushing the optical fiber 20 to thereby strip the coating 24 from the glass fiber 21.

  • Patent number: 8469076
    Abstract: The present invention relates to a polarizer film peeling machine and a polarizer film peeling method thereof. The polarizer film peeling machine includes an operation platform and a conveyor device having a translatable surface. The operation platform forms a slit at a site where a polarizer film is peeled off. The translatable surface of the conveyor device is located under the slit. In peeling off a polarizer film, a glass substrate from which the polarizer film is to be removed is set to slide on the a top surface of the operation platform to pass through the slit and the peeled-off polarizer film is guided through the slit to be laid flat on the translatable surface of the conveyor device and move with the translatable surface of the conveyor device.

  • Patent number: 8419896
    Abstract: A method for reworking a bonded display (e.g., a bonded LCD) having a substrate (e.g., plate or film) adhesively bonded to a face (e.g., front face) of the display. The method provides for efficient and clean removal of the substrate from the bonded display when necessary (e.g., when defect(s) are present) to afford a de-bonded display that is undamaged such that the resulting de-bonded display (e.g., de-bonded LCD) can subsequently be re-bonded as a component in a device being manufactured.

  • Patent number: 8211270
    Abstract: A method of detaching two plates adhered via an adhesive sheet or a curable resin layer, comprising moving, relatively parallel to each other, said two plates to develop a shear stress causing rupture of said adhesive sheet or curable resin layer. According to the present invention, two plates bonded via an adhesive sheet or a curable resin layer can be detached by only moving the two plates relatively parallel to each other. Therefore, even when at least one of the two plates is thin and poor in flexibility, two plates can be detached from each other substantially without a force (load) which causes high distortion (deformation) producing a breakage or crack on the plates. Accordingly, for example, when two optical plates adhered via a transparent adhesive sheet need to be re-bonded, two optical plates can be detached from each other and adhered again. Thus, the production cost of equipment with a display function, which carries a flat-panel display, can be reduced.
