  • Patent number: 6624571
    Abstract: There is disclosed an electroluminescent (EL) device accomplishing improved visual performance. The device has a transparent substrate on which a transparent electrode layer is formed. The transparent electrode layer is partitioned into segments to represent desired shapes in terms of pixels by selective emission of the segments. Parts of the transparent electrode layer are brought out toward the outer periphery of the transparent substrate to form terminals. Display electrodes, the terminals, and conductive interconnects that are different in function are formed from the transparent electrode layer. The conductive interconnects connect the display electrodes with the terminals. Other terminals for connection with a back electrode are also formed from the transparent electrode layer. An auxiliary electrode layer having a resistivity smaller than that of the transparent electrode layer is formed on the transparent electrode layer.

  • Patent number: 6211578
    Abstract: A instrumentation system is disclosed for providing improved reliability when used in a vehicle. The vehicle instrumentation system includes a plurality electronic component units and a reference portion which functions as a platform. The electronic component units have connecting portions, while the reference portion has mounting portions that have a plug-in structure. The electronic component units are mounted to the reference portion via the mounting portions. The vehicle instrumentation system receives current through the connecting portion of one of the electronic component units and through the connector of the reference portion. Current through the reference portion is prevented from introducing noise through the connecting portions of the electronic component units because it passes directly from the vehicle battery through a fuse box.

  • Patent number: 6211585
    Abstract: A stepping motor type indicator provided with unambiguous stable points having a holding force in a non-excited condition sufficient to suppress undesirable movements of a pointer. The stepping motor type indicator includes a stepping motor (2) having a rotor (28) with an output shaft (27) and stators (A, B). Yokes (23, 26) have a plurality of pole teeth (232, 233, 262, 263) extending toward curved outer surfaces of the rotor. The pole ends of a specific pole tooth (232a) chosen from one of the plurality of pole teeth is made to have a pole end area different than that of the remaining pole teeth. This structure produces unambiguous stable points (“a”-“l”) and produces strong holding forces so that an attractive force exerted by the stable point (“a”) on the pointer (4) toward stopper pin (7) is increased to positively suppress undesirable movements of pointer (4).
