Abstract: Provided herein is an orthodontic frame work and methods of making and using the same. The framework is configured to be placed within a dental arch nearby a tooth or teeth of a patient in combination with an appliance via an attachment for moving the tooth or teeth, the framework being less pliable than the appliance so as to serve as an anchor or a backbone of the appliance, the appliance is effective to move a tooth or teeth from an initial position to an intermediate position or final position of the tooth or teeth according to a prescription by a treating doctor, and the attachment is via a material forming the appliance and is configured to allow the framework to exert a non-reciprocal force upon the appliance and the appliance to exert a non-reciprocal force upon the tooth or teeth.

Abstract: Provided herein is an orthodontic hybrid appliance for moving one or more teeth of a patient and methods of making and using the same.

Abstract: A dielectric sheet having two layers made of different materials for forming a differential dielectric sheet on a plasma display panel, a plasma display panel using the same, and a manufacturing method therefor.

Abstract: A glass composition for a plasma display panel (PDP) and its fabrication. method are disclosed. The composition, comprising a ZnO—B2O3 group and alkaline earth metal oxide, is environment-friendly, has a high discharge efficiency and is used as various PDP dielectric materials. The fabrication method allows to compose the low melting point unleaded non-alkali glass composition at a low cost.

Abstract: An optical sheet and a backlight unit using the same are disclosed, in which deviation of a viewing angle is minimized to improve picture quality. The optical sheet includes a diffusion sheet provided with a plurality of diffusion patterns diffusing incident light in at least two directions to allow the incident light to have different strengths.

Abstract: The present invention relates to an apparatus for collecting soluble component-removed powder that collects soluble component-removed and poorly soluble component-containing powder to recycle by removing the soluble component from the powder through filtering using a vacuum pump after mixing soluble component- and poorly soluble component-containing powder and a solvent dissolving the soluble component, and a method of the same. According to the invention, it can be easily achieved to collect and utilize soluble component-removed powder, after the soluble component is dissolved in a solvent, by vacuum pumping the solvent through a filter and then discharging a solution containing only the soluble component, further effectively prevent overload by removing the soluble component-removed powder stuck on the surface of the filter in the vacuum pumping through backwashing.
