  • Patent number: 9612695
    Abstract: Providing a touch panel that suppresses reflection of light and prevents a reduction in the visibility of an image even when strong outside light is incident thereon in an outdoor environment. The touch panel has a plurality of first electrodes juxtaposed in parallel to each other in a first direction and a plurality of second electrodes juxtaposed in parallel to each other in a second direction. The first electrodes are continuously formed, the second electrodes are discontinuously formed, and a connecting electrode that electrically connects each parts of each of the second electrodes at a discontinuous portion is arranged under each of the first electrodes through an interlayer insulating film. A contour line provided to the interlayer insulating film arranged on the connecting electrode is formed to be curved under each of the first electrodes or the second electrodes.

  • Patent number: 9403119
    Abstract: An emission gas treatment apparatus recovers a recycle feed containing boron from emission gas discharged by a glass melting furnace. The apparatus includes a collection device for collecting a component containing boron from the emission gas by a wet process to obtain a collected liquid, a first filter for separating the collected liquid into a solid and a liquid, and an ion-exchange resin for forming a boron solution by removing an impurity from an extracted liquid obtained in the first filter. The apparatus also includes a mixing tank for mixing an extracted solid obtained in the first filter in the boron solution to form an extracted solid-containing solution, a second filter for separating the extracted solid-containing solution into a solid and a liquid, and a vacuum dryer for recovering the recycle feed from an extracted solid obtained in the second filter.

  • Patent number: 8525629
    Abstract: Provided is a reactor including a coil, and a core having an inner core portion arranged inside the coil and an outer core portion covering the outside of the coil. The inner core portion of the reactor has a higher saturation magnetic flux density than that of the outer core portion. The outer core portion has a lower permeability than that of the inner core portion, and is made of a mixture of a magnetic material and a resin. The case has a heat-transfer portion at an inner wall surface, as a heat-radiation structure for at least one of the coil and the inner core portion. With the reactor, even if the outside of the coil is covered with a core member, heat generated in the reactor can be effectively dissipated.
