  • Patent number: 6851639
    Abstract: A tape medium running device which can more correctly detect erroneous detection of a winding diameter, prevent an approach from being made to the end of the magnetic recording tape at high running speed and causing a damage on the tape, and can shorten fast forwarding/rewinding time. In this device, a winding diameter change detecting unit detects a change in winding diameter, and a ratio of a detected change in diameter and a maximum value of changes in winding diameter having been detected previously is compared with a predetermined winding diameter change comparison reference to detect abnormality. Thus, it is possible to prevent any approach from being made to the end of the magnetic recording tape at a high running speed based on an erroneous detection to causing a damage on the tape, and to shorten time for fast forwarding and rewinding.

  • Patent number: 6853139
    Abstract: The present invention has an object to provide a cold-cathode discharge lamp which can suppress sputtering on a lead-in wire and reduce consumption of mercury so as to achieve a longer lifetime without increasing an amount of applied mercury. The cold-cathode discharge lamp of the present invention is characterized in that a lead-in wire connected to a cylindrical electrode in a lighting tube is made of a material same as a material that forms the cylindrical electrode. It is possible to suppress concentration negative glow discharge shifted to the lead-in wire and to allow the electrode to be covered with even negative glow discharge. Thus, it is possible to reduce mercury consumed by excessive sputtering on the outer surface of the internal lead-in wire and to achieve a longer lifetime of the cold-cathode discharge lamp.
