  • Patent number: 11672163
    Abstract: An apparatus for manufacturing a display device, includes: a heater which generates heat; a pressing member which contacts a target object of a display device to transfer the heat to the target object; a body connected to each of the heater and the pressing member and through which the heat from the heater is provided to the pressing member; and a first housing cover extended from the body to surround the pressing member and the body in a plan view. Engagement of the first housing cover with the target object defines an internal space of the first housing cover having a temperature, and measurement by the apparatus, of the temperature of the internal space, controls bonding of layers of the target object to each other.
    Type: Grant

  • Patent number: 9469619
    Abstract: Provided is a two-step method of producing a compound of chemical formula 1 in the presence of an alcohol solvent and a Group 3B metal catalyst or a salt thereof, comprising a first step comprising alkylation or isomerization of an aldohexose-containing substrate to obtain an intermediate, and a second step comprising dehydration of the intermediate to produce a compound of chemical formula 1. Preferably, additional solvent and/or catalyst are not added in the second step.

  • Patent number: 8450234
    Abstract: The present invention relates to a catalyst used for producing dimethylether, a method of producing the same, and a method of producing dimethylether using the same. More particularly, the present invention relates to a catalyst used for producing dimethylether comprising a methanol synthesis catalyst produced by adding one or more promoters to a main catalyst comprised of a Cu—Zn—Al metal component and a dehydration catalyst formed by mixing Aluminum Phosphate (AlPO4) with gamma alumina, a method of producing the same, and a method of producing dimethylether using the same, wherein a ratio of the main catalyst to the promoter in the methanol synthesis catalyst is in a range of 99/1 to 95/5, and a mixing ratio of the methanol synthesis catalyst to the dehydration catalyst is in a range of 60/40 to 70/30.
