    摘要: A supporting device for a display unit for rotating a display screen to be oriented vertically. The supporting device includes a fixed member mounted on a base, an elevating member secured to the fixed member to be lifted or lowered, a pivot bracket rotatably coupled to an upper end of the elevating member while being secured to a rear surface of the display unit, an operating lever having an upper portion rotatably coupled to the upper end of the elevating member, a holder formed at the fixed member to allow the operating lever to be caught therein when being rotated rearward in a lifted state of the elevating member, a horizontally movable member secured to the upper end of the elevating member, and a cam portion formed at the pivot bracket.

    摘要: Disclosed is a process for preparing dimethyl ether, including a) reacting methanol containing 0-80 mol % of water in the presence of a dehydration catalyst, b) transferring the reaction product into a single separation column, thus separating dimethyl ether, water, and unreacted methanol, c) withdrawing dimethyl ether and withdrawing unreacted methanol from the sidestream of the single separation column, and d) recyling the unreacted methanol to the a) reacting the methanol. Dimethyl ether may be prepared from water-containing methanol, and the separation and withdrawal of dimethyl ether, water, and unreacted methanol may be realized using a single column, thus reducing the investment cost and the operating cost.
