Title: Liquefied natural gas
Inventor: MASUDA NOBUYUKI
IPC: F17D1/20
Filed: 2001-11-12
Abstract: PROBLEM TO BE SOLVED: To ensure a necessary effective suction water head of an LNG pump without a large scale construction work and equipment work. SOLUTION: A daily container 9 smaller than an LNG tank is situated between the LNG tank 2 and the LNG pump 3. A pressure vaporizer 19 is connected to the daily container 9 through an out-line 20 and in-line 21, LNG delivered out from a liquid phase part to the out-line 20 is gasified through heat exchange with the atmosphere and delivered in the air phase part of the daily container 3.

Title: Method for measuring physical property of liquid near interface
Inventor: SAKAI MARI
IPC: G01N11/00
Filed: 2001-11-13
Abstract: PROBLEM TO BE SOLVED: To accurately measure the physical properties of a liquid near the interface. SOLUTION: On a QCM (Quartz-Crystal Microbalance) electrode, a droplet of a sample liquid for the measurement of the physical properties is discharged and a liquid film with a predetermined film thickness is formed by this sample liquid. Then, the shift value of the QCM's resonant frequency due to the forming of this liquid film is measured. Since the resonant frequency and the viscosity coefficient of the sample liquid are related in prescribed formula, the viscosity coefficient of the sample liquid can be measured from the measured shift value. Therefore, if the droplet is discharged and the liquid film is formed, it is possible to accurately measure the physical properties of the liquid near the interface of the liquid film as the liquid film with the desired film thickness can be formed quickly.
