  • Patent number: 11335491
    Abstract: The present invention controls the pressure and flow rate of fluid, in order to obtain uniform performance, configure a closed loop magnetic circuit so as to include an electromagnet, a flapper, and a yoke material, and elastically deform the flapper itself by Maxwell attractive force generated between a magnetic pole of the electromagnet and the flapper to make the separation distance between the nozzle and the flapper variable. As opposed to a rigid flapper structure that swingably moves around a supporting point, like a conventional servo valve, the electromagnet, the magnetic pole, the nozzle, the flapper, and the like are arranged such that a change in magnetic gap directly leads to a change in air gap.

  • Patent number: 8003206
    Abstract: An optical laminate is provided, which prevents the occurrence of interface reflection and interference fringes at the interface between a light transparent base material and an antistatic layer has been effectively prevented. The optical laminate includes a light transparent base material and an antistatic layer and a hardcoat layer provided in that order on the light transparent base material. The hardcoat layer is formed on the antistatic layer using a composition for a hardcoat layer including a resin and a penetrative solvent. The penetrative solvent penetrates into the antistatic layer and the light transparent base material so that the antistatic agent contained in the antistatic layer disperses into the antistatic layer or the light transparent base material.
