20150056565 | TOOL FOR BONDING ORTHODONTIC BRACKET - The present invention relates to a tool for adhering an orthodontic bracket, comprising: a pair of bracket holding portions for holding a bracket to be bonded to teeth while approaching or separating from each other; and a pair of handle portions connected to the pair of bracket holding portions, for controlling the bracket holding portions to allow the same to approach or separate from each other, wherein a scale for measuring the height of a bracket for the end of teeth is formed in at least any one of the pair of bracket holding portions. Therefore, an operation is convenient, measurement is easy and measurement time can be reduced since the tool has a simple and uncomplicated structure. In addition, it is possible to improve the effectiveness of orthodontic treatment since a bracket can be bonded by precisely setting the height of the bracket. | 02-26-2015 |

20090021325 | FRONT-END MODULE - A front end module is disclosed. The front end module includes a plurality of antennas receiving different frequency band signals, respectively, an impedance matching circuit unit comprising a plurality of tuners respectively connected to the plurality of antennas to control impedance matching, a selection unit selecting one frequency band signal from multiple frequency band signals passing through the impedance matching circuit unit, a measuring unit measuring signal strength of a received signal selected at the selection unit, and a control unit controlling an operation of the selection unit and an impedance of the tuner according to the signal strength of the received signal measured at the measuring unit. | 01-22-2009 |
20090038141 | METHOD FOR MANUFACTURING ANTENNA - Provided is a method for manufacturing an antenna which is minimized and used in a low frequency band. The method includes forming and preparing a radiator for an antenna, mounting the radiator inside a dam molding part including an upper dam molding part and a lower dam molding part, injecting a molding material into the dam molding part through an inlet provided at one side of the dam molding part, the molding material including a composite material with a controlled diameter and content, hardening the injected molding material, and separating the hardened molding material covering the radiator from the dam molding part. Accordingly, a miniaturized antenna can be provided, which can achieve a high integration density, prevent deformation of the radiator caused by external pressure generated in processes, and be used in a low frequency band by covering the radiator with a molding material having a high permittivity and a low-loss characteristic. | 02-12-2009 |
