摘要： PURPOSE:To enable lifting/lowering of machineries through control of a heating means, by making a gas vent communication section and a liquidized gas communicating section respectively through the upper and lower portions of a storage chamber arranged on the body while furthermore providing a heating means in the storage chamber. CONSTITUTION:Machineries 9 such as a density meter are secured to proper positions of a body 1 which is floated in liquidized gas 10 in a liquidized gas tank 8 and supported, where said machineries 9, a valve 3 and a heating means 6 can be controlled from the upper section of the liquidized gas tank 8 through a control cable 7. When the heating means 6 is operated under the state where the valve 3 is closed, ratio of vaporized gas increases in the storage chamber 2, thereby buoyancy of the body 1 increases to float the machineries 9. When the heating means 6 is stopped to open the valve 3, buoyancy of the body 1 decreases to sink the machineries 9.

摘要： PROBLEM TO BE SOLVED: To provide a monitor system for a mobile machine inside the piping, capable of maintaining its constant and steady operation without any reliance on a manipulator's skill, preventing the machine itself from risking misoperation and damage, and retarding the degradation of the machine life due to excessive expansion. SOLUTION: This system has a monitor device 1 and the mobile machine 5 being connected to the monitor device I through a piping body 3 inclusive of a medium-supply tube 25. The mobile machine 5 possesses a position-fixing body 23 that is expandable or shrinkable due to the inflow and outflow of a medium, thereby letting the machine 5 itself fixed or released, correspondingly. The monitor device 1 has a measurement section 11, an identifying section 13, a control section 15 and an indicating section 17. The measurement section 11 measures the flow, the pressure and the temperature of the medium or the like. The identifying section 13 identifies what a state the position-fixing body 23 is in, based upon the measurement results obtained by the measurement section 11. The control section 15 controls the inflow and outflow of the medium, based upon the identified results obtained by the identifying section 13.

摘要： PROBLEM TO BE SOLVED: To mount a new microwave type level gage to the existing tank under its pressurized operation without opening the tank when recovery is impossible due to trouble at the gate. SOLUTION: A sealed pipe 7 is mounted at a shut-off valve 11 on the existing pipe 10 mounted to an existing tank 12, an antenna adapter 4 of the outer diameter size for holding a hermetical sealing between the pipe 7 is mounted at the outside of the tapered surface 3a of a horn antenna 3, and the profile of the antenna 3 is formed in a straight state. Then, the adapter 4 is inserted into the pipe 7 to hold the sealability so that the pressure in the tank 12 is not released, and hence mounting operation is conducted in the pressure operating state.

摘要： PROBLEM TO BE SOLVED: To improve the reliability, simplify the equipment, and reduce the equipment cost of the purging method in an anhydrous LNG sampling system. SOLUTION: In performing the total system purge, a sampling gas is pushed out through a sampling gas filling line 9, a sampling gas filling apparatus 10 (a sampling gas cylinder 11), and escape line 12, and a BOG line 13 in this order while supplying the sampling gas into the outer layer 8b and the inner layer 8c in a sampling gas holder 8 alternately. In performing the cylinder purge, the following procedure is repeated several times: a pressurized gas is introduced through a pressurized gas charge line 14 into the inner layer 8c to push out a sampling gas (which is collected in the outer layer 8b) through a sampling gas filling line 9 into a sampling gas cylinder 11, and the sampling gas in then discharged through the escape line 12.

摘要： PROBLEM TO BE SOLVED: To reduce the amt. of water sprayed in an LNG vaporizer to thereby reduce the power cost of a seawater pump. SOLUTION: In the method for running a seawater pump 8 by calculating the amt. of seawater supplied by the pump 8 by using the higher value of the two amts. of water: the necessary amt. of sprayed water obtd. by comparing the temp. of seawater at the entry side of an LNG evaporator 1 to be monitored with the designed conditions of the evaporator 1 and the amt. of sprayed water at the film-breaking limit, as the set amt. of sprayed water, the temps. of sprayed water at tubes 4 near the lower header part 3 of the panel 5 of the evaporator 1 are measured along the right-and-left direction to calculate the difference between each of the above-obtd. temps. and the temp. of seawater at the entry sides of each of the tubes 4; then the apparent amt. of sprayed water is calculated about each tube from the above-obtd. temp. difference, the flow rate of the LNG, the enthalpies of the entry-side LNG and the exit-side gas, and the specific heat of water sprayed; and the amt. of seawater supplied by the pump 8 is increased when the apparent amt. of sprayed water becomes lower than the above set amt.

摘要： PURPOSE: To prevent damage due to expansion and contraction by a temperature change by housing a lamp main body in a protective tube, and making a space between the protective tube and a lamp vacuous. CONSTITUTION: A cylindrical lamp main body 11 is housed inside a protective tube 12 put in a sealed condition. This main body 11 is arranged so as not to contact with an inner wall of the protective tube 12 by a support part 13 installed in a sealing part 14. A conductor 22 is connected to a stem pin 21, and extends inside of the protective tube 12, and a lamp support plate 23 is installed on one end which is not connected to the stem pin 21 of this conductor 22. In this low temperature lamp 10, the lamp main body 11 is housed in the protective tube 12, and since a space between the protective tube 12 and the main body 11 is made vacuous, influence on the main body 11 by an external sudden temperature change is relieved, and even if it is placed in cryogenic fluid, since a temperature of the main body 11 does not become a low temperature so much, damage and a burst due to expansion and contraction by a temperature change can be prevented.
