Title: Device for measuring non-methane hydrocarbon
Inventor: UCHIDA KENICHI
IPC: G01N30/88
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To measure the concentration of non-methane hydrocarbon quickly and accurately by judging whether methane has completely flown out of a main separation column on back flush. SOLUTION: When a non-methane hydrocarbon remains in a main separation column 4 in a mixed gas, methane flows out of the main separation column 4. A mixed gas flowing out of the main separation column 4 flows into a main channel 12 and a branch channel 17. The mixed gas flowing into the main channel 12 flows into an auxiliary separation column 6. On the other hand, the mixed gas passing through the branch channel 17 flows into an auxiliary hydrocarbon detector 7, the concentration of hydrocarbon is detected, and the detection value is sent to a methane flow-out completion judging device. A methane flow-out completion judging device judges whether methane has completely flown out of the main separation column 4 or not.  More specifically, the device judges whether back flush switching timing is too fast or not and whether a separation in the main separation column 4 is appropriate or not.

Title: Energy producing plant utilizing latent heat of ice
Inventor: KONDOU MASANOBU
IPC: F03G7/05
Filed: 1979-01-22
Abstract: PURPOSE: To obtain energy by performing the same cycle as steam turbine by use of a work medium having a low boiling point, while keeping a temperature difference between iced water and atmosphere or sea water through the ulilization of latent heat obtained when ice is molten and water is frozen.  
     CONSTITUTION: When temperature of the atmosphere or sea water is higher than about 15°C, they serve as fuel and furnish heat to a work medium in an evaporator, where work medium is evaporated into vapor. The vapor is ejected to turbine, thus giving energy thereto, and then discharged to a condenser. The condenser is cooled by iced water so that vapor in the condenser is liquefied. Here, ice is molten by depriving the latent heat and liquefied work medium is sent to evaporator by means of pump. By repeating the above cycle, energy can be obtained. On the other hand, if temperature of the atmosphere is lower than about 15°C, water may serve as fuel.
