  • Patent number: 8457907
    Abstract: A compensation device for fluidic oscillation flow meters is provided. The compensation device includes a fluid supply unit, a fluidic oscillator, an electronic valve, a reference tank and a computer. The fluid supply unit supplies fluid into a pipe. The fluidic oscillator generates a characteristic oscillation frequency when the fluid supplied from the fluid supply unit passes through the fluidic oscillator. The electronic valve controls a flow rate of the fluid passing through the fluidic oscillator. The reference tank accumulates and stores the fluid passing through the electronic valve. The computer calculates a characteristic linear compensation coefficient using data about the time for which the fluid had passed through the fluidic oscillator, an oscillation frequency of the fluidic oscillator, a preset flow rate of the electronic valve, and a preset fluid accumulation amount of the reference tank. The computer stores the calculated characteristic linear compensation coefficient.

  • Publication number: 20090252967
    Abstract: A CNT transparent electrode may have a CNT layer consisting essentially of CNT only, together with a cover layer that may include conductive particles and a polymer. The cover layer may cover an upper and/or a lower portion of the CNT layer. The CNT transparent electrode including the CNT layer which essentially consists of CNT only and does not contain other materials such as a binder or a dispersing agent can exhibit excellent conductivity. When the CNT layer is covered by the cover layer, surface roughness, film uniformity, adhesion between the CNT transparent electrode and the substrate and stability in the process of applying the CNT transparent electrode to devices can be enhanced, compared to the case where only the CNT layer is used.
