  • Publication number: 20110200945
    Abstract: An alignment mark having high precision and good visibility is formed in a simple manner without modification of a manufacturing line or a significant increase of man hours and a flat panel display is manufactured at low cost and with good productivity. To achieve this, the method includes a step of forming a photosensitive film on a substrate, a step of forming an alignment mark by exposing the photosensitive film by using an exposing mask, and a step of performing position alignment by recognizing the alignment mark in an undeveloped state of the photosensitive film.

  • Patent number: 6512632
    Abstract: A drive mechanism includes a fine-movement ring provided at each of both ends of a fine-movement coupling shaft, disposed outside each of rough-movement handles, and having a smaller outside diameter than an outside diameter of each of the rough-movement handles, and a fine-movement handle detachably attached to at least one of the fine-movement rings.

  • Patent number: 6285000
    Abstract: The two ends of an article to be processed which is in the form of a sheet are held by means of a fixed clamp and a movable clamp, the article being held by applying bias by means of a biasing cylinder to the movable clamp in a direction such as would separate it from the fixed clamp and hole-forming processing being performed by means of a laser beam. Since the sheet-like article is held under tension, flatness of even a thin sheet can be maintained and since the underneath space is open, there is no reflection of laser light after passing through the holes that are formed and any processing waste can easily be removed.
