A loop heat pipe system includes: a loop heat pipe (LHP) including an evaporator, a condenser, a vapor line, and a liquid; a temperature sensor to measure temperature of part of the LHP, a working fluid portion in which has different phases in a situation where the LHP functions as a heat transport device and in a situation where the LHP dose not function as a heat transport device and a liquid phase of the working fluid dose not exist in the evaporator; a heater to heat a heating target part of the vapor line; and a controller, in order to start the LHP, to turn on the heater, to monitor temperature of the heating target part using the temperature sensor, and to turn off the heater when detecting a change caused by condensation of a vapor phase of the working fluid in the monitored temperature.
摘要:
A position of a mobile communication terminal in an environment where the terminal cannot communicate with a GPS is defined more narrowly than a sector area of a base station in which the mobile communication terminal is located so that the position of the mobile communication terminal can be estimated more accurately. Even if a mobile communication terminal is in an environment where the terminal cannot communicate with a GPS, the latitude and longitude of the center of a sector of the wireless base station in which the mobile communication terminal is located is obtained according to a predetermined calculation by a base station database device, and the obtained latitude and longitude is sent back as an estimated latitude and longitude of the mobile communication terminal to the mobile communication terminal via the wireless base station.

A position determination system includes a mobile terminal configured to receive GPS information from a GPS; a base station device configured to measure a round trip time (RTT) from the mobile terminal; a base-station position table unit configured to store position information on the base station device; a cable-length table unit configured to store a cable length between the base station device and an antenna assembly provided to the base station device, the antenna assembly communicates with the mobile terminal; and a position determination device configured to determine the position of the mobile terminal on the basis of the round trip time measured by the base station device, the cable length obtained from the cable-length table unit, the position information on the base station obtained from the base-station position table unit, and the GPS information received from the mobile terminal.
摘要:
A loop heat pipe system includes a loop heat pipe (LHP), a temperature sensor, a heater and a controller. The temperature sensor measures temperature of a working fluid portion of the LHP in which the working fluid has different phases depending on whether or not the LHP is in a disable status not to start up a heat transportation, in which a liquid phase of the working fluid does not exist in an evaporator of the LHP. The heater heats a heating target part of a vapor line. The controller, in order to start up the LHP, turns on the heater, monitors temperature of the heating target part using the temperature sensor, and turns off the heater when detecting a change in the monitored temperature, caused by condensation of a vapor phase of the working fluid.
