Pier copings are formed by placing and curing concrete in the through holes. Rubber bearings(11) are installed on the lower connecting support members. Prestressed concrete girders(20) are installed on the rubber bearings. Girder connection units(100) connect the prestressed concrete girders. Non-shrinkage concrete is placed in the girder connection units.

Title: Method for controlling power transmission in wireless power transmission apparatus and wireless power transmission apparatus thereof
Inventor: JUNG CHUN KIL
IPC: H02J7/00
Filed: 2011-03-23
Abstract: PURPOSE: A power transmission control method and a power transmission device in a wireless power transmission device are provided to effectively control wireless power transmission by detecting foreign materials between the wireless power transmission device and a wireless power reception device. CONSTITUTION: A primary core(110) transmits a wireless power signal and a pulse signal to a wireless power reception device side. A sensor(126) senses foreign materials during wireless charging. A transmission controller(120) calculates the power loss of the wireless charging according to the sensing condition of the foreign materials disposed on the charging position of the wireless power transmission device. The transmission controller controls the primary core for stopping the power transmission in a power loss state over a reference value. The sensor is composed of an infrared sensor.

Title: Device for removing resist and mask blank and method for manufacturing omask blank
Inventor: NAM KEE SOO
IPC: G03F7/26
Filed: 2011-04-08
Abstract: PURPOSE: An apparatus for removing a resist film, a mask blank, and a method for manufacturing a mask blank are provided to produce a high quality mask blank by eliminating an unnecessary resist film from a peripheral region. CONSTITUTION: An apparatus for removing a resist film includes a dissolution agent supply nozzle(23) and an exhaust unit The dissolution agent supply nozzle supplies a dissolution agent, dissolving the resist film, to an edge of a substrate. The exhaust unit is arranged to be adjacent to the edge of the substrate. The exhaust unit inhales the resist film dissolved with the dissolution agent and discharges. The exhaust unit includes a top inhaler(21) and a low inhaler(22).
