  • Patent number: 6467667
    Abstract: Device for severing at least one optical fiber When severing optical fibers (1) with conventional severing devices, after the severing operation the severed fibers (1) are distributed in a disorderly manner on the second fixing element (26), with the result that they can only be removed with difficulty and laboriously. Using a bonding device (20, 21) in the form of a rocker (21) with an adhesive strip (20), the fiber ends are adhesively bonded on during the severing operation, with the result that they remain in an orderly manner on the adhesive strip after the severing operation. The rocker (21) is in this case mounted such that it can pivot between an inserting position and a severing position, in order to facilitate the insertion of the fibers (1).

  • Patent number: 6412677
    Abstract: There is disclosed a method of cutting a plate glass mother material in which a plurality of grooves are scribed/processed beforehand on one main surface, and appropriate pressing is constantly performed, so that more preferable materials to be pressed can be formed. When a plate glass mother material 20 is pressurized by an indenter 191, and cut in a portion of groove D1, vibration is momentarily generated. The vibration is transmitted to a vibration sensor 193 via an indenter base 190. Subsequently, at the time when the vibration sensor 193 detects the vibration, a Z-axis servo motor 192 of a pressing device 19 stops, and pressing by the indenter 191 stops. Therefore, the indenter 191 does not advance by more strokes than necessary, glass in a cut portion can be prevented from being chipped.

  • Patent number: 6337943
    Abstract: A device is for fixating a fiber ribbon cable in a ribbon fiber cutting machine. A fixture or jig holding a stripped fiber ribbon cable is placed on the cutting machine in a predetermined position, by placing the jig in a machine-mounted holder and pressing the jig against one side thereof. The jig is positioned so that the ribbon fibers will enter respective V-grooves on a first support and engage a resilient surface on a second support. The fibers can be linearised in the grooves on said support surface, despite possibly being deformed when stripping the cable, by angling the jig in relation to said V-grooves on said support surface. The fibers are pressed down into the grooves, thereby fixating the fibers in both a vertical and a lateral direction. The fibers will also be parallel with one another in the space between said support. Arranged in said space is a knife by means of which a fracture line or weakening is made on the fibers.

  • Publication number: 20010048014
    Abstract: A method of producing a semiconductor device of the present invention is applicable to a multilayer wafer for leadless chip carrier packages and breaks it on a package basis. The method begins with a step of forming a generally V-shaped groove in one major surfaces of the wafer in the direction of thickness of the wafer. A weak, cleaving portion is formed in the other major surface of the wafer in alignment with the groove. A cleaving force is exerted on the wafer to thereby form a break in the cleaving portion, so that the wafer is caused to break from the groove toward the cleaving portion in the direction of thickness of the wafer. The cleaving portion may be replaced with a strong, non-cleaving portion, in which case the break is formed in the interface between the non-cleaving portion and the wafer due to a difference in cleaving force.
