摘要: PURPOSE: A method for detecting a gas leaked position of a gas pipe is provided to rapidly and accurately grasp a gas leaked position in a gas piping composed of a plurality of pipes. CONSTITUTION: A method for detecting a gas leaked position of a gas pipe is as follows. Gas pressure in the inside of a gas pipe is successively sensed per every set time periods with two or more gas pressure sensors are installed in a plurality of gas pipes(S101). Gas pressure sensing signals sensed by the selected two gas pressure sensors among gas pressure sensors are respectively integrated with respect to elapsed time per each time period(S105). A correlation value of the sensing signals of the two gas pressure is obtained by integrating a multiplied value of the sensing signals of the two gas pressure respectively integrated(S109). When the correlation value at one or more time points of the corresponding time period is over a reference value set in advance, a gas leaked position of the gas pipe is calculated by using a time interval between the time point corresponding to the highest correlation value and an in-between time point of the time period(S115).

摘要: A temperature controller of a nano imprint apparatus and a nano imprint apparatus including the same are provided to reduce a manufacturing cost of the nano imprint apparatus by controlling arbitrarily and freely an installation position. A heat exchange pin(100) is composed of a heat-conducting material and includes a plurality of air flow paths. A first thermoelectric module(200) is coupled with the one side of the heat exchange pin in order to connect a heat-absorbing reaction part. A second thermoelectric module(300) is coupled with the heat exchange pin in order to connect a heat-radiating reaction part with the other side of the heat exchange pin. An air suction tube(400) is used for forming an air suction path from the inside of the chamber to the air flow path of the heat exchange pin. An air discharge tube(500) is used for forming an air returning path to the inside of the chamber through the heat exchange pin. A temperature sensor(600) senses the temperature of the air through the air suction tube or the air discharge tube. A temperature control unit(700) compares the temperature received from the temperature sensor with the reference temperature and supplies selectively the power to the first and second thermoelectric modules.
