  • Patent number: 7959989
    Abstract: The present invention relates to a novel cyclic olefin compound, a polymer including the cyclic olefin compound, a liquid crystal alignment film including the polymer, and a liquid crystal display device including the liquid crystal alignment film. Since the polymer includes the cyclic olefin compound as a main chain, the thermal stability is excellent and the photoreactive speed is high. Accordingly, the production time can be reduced, the production cost can be reduced, and the anchoring force of the liquid crystal can be increased because the alignment property is stabilized due to the curing.

  • Patent number: 7812445
    Abstract: Provided is a semiconductor memory module allowing a filling member formed between a module substrate and memory chips mounted on the module substrate to completely fill the space between the module substrate and the memory chips. According to embodiments of the present invention, the semiconductor memory module includes a module substrate having at least one memory chip mounted on the substrate such that its edges are oblique to major and minor axes bisecting the module substrate. The oblique orientation allows for an improved opening between memory chips formed on the substrate so that the filling member may be properly formed between the module substrate and the memory chips to prevent voids where the filling member is not formed.

  • Publication number: 20100173386
    Abstract: Provided is a prokaryotic expansin protein capable of expanding cellulose. The prokaryotic expansin protein performs the same function as existing plant expansin proteins. The prokaryotic expansin protein can be produced at greatly reduced cost on an industrial scale, unlike plant expansin proteins. Particularly, when lignocellulosic biomass is hydrolyzed into glucose using the prokaryotic expansin protein and cellulase, the hydrolysis rate of cellulose can be markedly increased by the cellulase, resulting in improved yield of the glucose. In actuality, the use of the prokaryotic expansin enables the production of bioenergy at low cost with a reduced amount of enzyme used. The prokaryotic expansin protein softens the textures of pulp, cotton fibers (e.g., jeans), etc. Therefore, the prokaryotic expansin protein can be used for various purposes, such as biopulping and biostoning.
