  • Patent number: 5548421
    Abstract: A plasma addressing electro-optical device including a first substrate having a major surface: a plurality of first electrodes formed on the major surface of the first substrate so as to extend in substantially parallel relationship to each other; a second substrate having a major surface opposed to the major surface of the first substrate; a plurality of second electrodes formed on the major surface of the second substrate so as to extend in substantially parallel relationship to each other to generate plasma addressing between adjacent ones of the second electrodes; an electro-optical material layer formed between the first substrate and the second substrate; and a plasma discharge chamber formed between the electro-optical material layer and the second substrate so as to seal an ionizable gas therein. The plasma discharge chamber has a height of about 75% or more of a distance between the adjacent ones of the second electrodes.

  • Patent number: 5525862
    Abstract: An electro-optical device applied as an image display device includes a first substrate having a plurality of non-overlapping first electrodes on a major surface thereof; and a second substrate opposed to the first substrate and having a plurality of non-overlapping second electrodes on a major surface thereof wherein the second electrodes are disposed substantially perpendicular to the first electrodes. This device further includes an electro-optical material layer disposed between the first and second electrodes; and a discharge chamber disposed between the electro-optical material layer and the second substrate, and filled with an ionizable gas, the discharge chamber having a plurality of scanning units, the scanning units being divided by partition walls formed by a printing process. By formation of grooves by the printing process, the difficult process of etching of grooves or formation of electrodes in the grooves is unnecessary, and the manufacturing is easy.

  • Patent number: 5526151
    Abstract: A plasma addressed liquid crystal display device having a plasma cell and a liquid crystal cell stacked one above the other is manufactured by a method of forming stripe-shaped barrier ribs by printing to a substrate on which a plurality of plasma electrodes are previously formed, filling a temporary reinforcing material between each of the stripe-shaped barrier ribs to bury the periphery of the individual barrier ribs, polishing to planarize a top portion of each of the barrier ribs buried in the reinforcing material, removing the temporary reinforcing material to expose the plasma electrodes and finally joining a dielectric sheet in contact with the planarized top portions of the barrier ribs, to assemble a plasma cell. Barrier ribs formed in the plasma cell of the plasma addressed liquid crystal display device can be polished stably with no worry of destruction.

  • Patent number: 5420707
    Abstract: A plasma addressing electro-optical device having an improved surface electrode structure which miminizes the structure of a plasma cell and is capable of producing stabilized plasma discharge. The plasma addressing electro-optical device includes a first substrate having a plurality of first electrodes which are arranged substantially in parallel to each other on a major surface, and a second substrate which is opposed to the first substrate and has a plurality of second electrodes which are arranged substantially in parallel to each other on a major surface thereof so as to define an addressing unit for plasma discharge between the inside wall surfaces of adjacent ones of the second electrodes. The second electrode each function as an anodes and a cathode and preferably have a height of 100 .mu.m or more.

  • Patent number: 5167162
    Abstract: In a starter system for an internal combustion engine, an input member of an overrunning clutch is provided with an annular shoulder surface abutting an annular end surface of a cylindrical boss portion of a reduction gear unit casing when the overrunning clutch is at a rest position, and a cylindrical sleeve portion extends from the annular shoulder surface towards the reduction gear unit so as to be closely fitted on the cylindrical boss portion of the reduction gear unit casing. Thus, water and other foreign matters are not only shut off by these mutually abutting annular surfaces, but also prevented from reaching this region by the cylindrical sleeve portion closely fitted on the cylindrical boss portion of the reduction gear unit. Also, the centrifugal force prevents water and other foreign matters from reaching this area when the starter is actuated and the two annular surfaces are not in contact.
