Abstract: A display device includes a display panel including a first non-folding area, a second non-folding area, and a folding area that are arranged along a first direction, the folding area being foldable along a folding line extending along a second direction intersecting the first direction, a panel lower member disposed below the display panel, and a digitizer disposed below the panel lower member and including a base layer and sensing coils. The base layer includes a folding portion including holes overlapping the folding area of the display panel and first and second non-folding portions disposed along the first direction. The folding portion is disposed between the first and second non-folding portions. The sensing coils are disposed on the base layer, and the base layer includes a matrix including a filler and an elastomer and weaving-shaped fiber lines disposed inside the matrix and alternately arranged with each other.

Abstract: The present invention relates to a pharmaceutical composition for preventing or treating obesity or diabetes, and to a food composition and feed composition for preventing or alleviating obesity or diabetes, comprising as an active ingredient, an Acanthopanax extract, a garcinia cambogia extract, or compounds isolated therefrom. The composition has synergistic antidiabetic and antiobesity activity compared to that of using only an Acanthopanax extract, a garcinia cambogia extract, or compounds isolated therefrom. Therefore, it is possible to reduce the possibility of any side effects that may be caused by an overdose of or long-term administration of the garcinia cambogia extract and a substance isolated therefrom, and thus the composition can be very effectively utilized in the development of a therapeutic agent for diabetes or obesity.

Abstract: The present invention relates to a method for preparing a perfluorodialkyl ether, comprising the steps of: (A) preparing a perfluorodialkyl ether from a compound represented by Formula 1 in the presence of a metal fluoride; and (B) isolating the perfluorodialkyl ether, and to an apparatus for preparing perfluorodialkyl ether, comprising: a reactor for preparing a perfluorodialkyl ether from a compound represented by Formula 1 in the presence of a metal fluoride; a reactant supplier for introducing the compound represented by Formula 1 into the reactor; and a discharge unit for discharging the perfluorodialkyl ether from the upper portion of the reactor.

Abstract: The DC interrupting device includes a main current conduction unit including a main interrupting switch, which is a mechanical switch, a reverse current power supply unit connected to an input terminal of the main current conduction unit and configured to generate a predetermined reverse current, and a reverse current conduction unit configured to supply the reverse current to an output terminal of the main current conduction unit. The reverse current power supply unit includes a first reverse current dedicated capacitor charged by a voltage applied to an input terminal of the main current conduction unit, a polarity reversing inductor configured to reverse a polarity of the first reverse current dedicated capacitor, and a reverse current power supply unit switch configured to perform circuit connection such that the polarity reversing inductor reverses the polarity of the first reverse current dedicated capacitor.
