  • 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.

  • Publication number: 20090231325
    Abstract: In a display device having a video signal drive circuit disposed laterally adjacent to the screen, the frame area is reduced and the vertical line noise at the center of the screen is prevented from appearing. Driver lines are drawn to areas disposed above and below a display area from the video signal drive circuit. R, G, and B drain lines are branched from each of the driver lines via R, G, and B switches. The R, G, and B switches are driven by R, G, and B switching lines. In order for preventing the interference between the driver line for supplying the center area of the screen with the image signals and the B switching line, a shield line is disposed between the driver line and the B switching line.
