  • Publication number: 20160139710
    Abstract: A method for patterning a light transmitting electrically conductive member uses a light transmitting laminate material in which an electrically conductive layer including an overcoat layer and silver nanowires embedded therein is formed on a surface of a light transmitting base film and includes a step of treating a surface of the electrically conductive layer which is not covered with a resist layer using an iodine solution to at least partially iodize the silver nanowires and a step of applying a thiosulfate solution to the surface of the electrically conductive layer which is not covered with the resist layer to remove a silver iodide exposed to a surface of the overcoat layer. Since a white cloudy or a whitened silver iodide is removed, the optical transmission characteristics of the non-electrically conductive region can be improved.

  • Publication number: 20150221413
    Abstract: A conductor includes: a transparent conductive film which is formed on a transparent substrate and includes a silver nanowire; and a metal film of which at least a portion is formed to overlap the transparent conductive film, in which a portion in which the transparent conductive film and the metal film overlap each other includes a buffer film which has adhesion to each of the transparent conductive film and the metal film and does not impede conduction between the transparent conductive film and the metal film. Preferably, the buffer film is, for example, an ITO film, and at this time, an upper surface of the transparent conductive film is a reverse-sputtered surface.

  • Patent number: 5300917
    Abstract: A junction box incorporating an integrally formed shunt busbar. The shunt busbar incorporates a first pair of terminals to act as leads to couple the shunt busbar in a current loop of a circuit, and a second pair of terminals to couple a voltage sensing device across a portion of the shunt busbar. The voltage sensing device is preferably a high input impedance voltage comparator. The input impedance of the voltage comparator is great enough to negate the affect of the internal resistance of the mating terminals of the busbar. Furthermore, the second pair of terminals is located on the shunt busbar such that the terminal resistances thereof are outside of the current loop. The electrical busbar is preferably mounted in a suitable insulating housing. When the shunt busbar of the present invention is connected to the high input impedance voltage comparator, a circuit path that allows for easily and accurately measuring the voltage drop across the busbar is made possible.
