摘要： PURPOSE:To enhance regeneration efficiency of an absorbing liquid, in a device contacting absorbing liquid to carbon dioxide gas in the exhaust gas of an engine to remove the gas, by utilizing thermal energy of the exhaust gas and a lubrication oil as a heating source for regenerating the absorbing liquid. CONSTITUTION:The exhaust gas of a diesel engine 1 is supplied through a turbine 2 of a supercharger, heat exchanger 3 and cooler 30, together with O2 gas from an oxygen supply pipe 7. A cooling water in the engine 1 is recycled to the engine 1 through the heat exchanger 3 and a regeneration tower 17, while a lubrication oil is cooled by a heat exchanger 11 and thereby it is recycled. A part of this exhaust gas is fed to an absorbing tower 13 by the operation of a fan 12 to absorb carbon dioxide gas into an absorbing liquid, and then a rich absorbing liquid E absorbed the carbon dioxide is heated by the heat exchangers 14, 11, and it is flashed thereafter from the top of the regeneration tower 17. It is thus possible to discharge the carbon dioxide to recycle the leaned absorbing liquid to the absorption tower 13.

摘要： PURPOSE:To obtain a largest possible amount of displacement for a given draft and facilitate work by adopting a lower hull configuration with a midship section composed of a straight line bottom whose both sides are connected to circular are portions. CONSTITUTION:A cross section configuration of a lower hull consists of a straight line 6a at least for a bottom having circular arc portions 6b, 6b on both sides. Circular portions 6b, 6b may be of a semicircular form or a part of a circumference. A top 6c may be either straight line or curve, but preferably consists of a straight line being in parallel to the straight line 6a. The lower hull 6 with such a cross section configuration is capable of obtaining a maximum sectional area for a given hight H, a maximum displacement for a fixed value of draft and also a most shallow draft for a given displacement. The proposed configuration is a combination of straight lines and circular arcs and contributes to facilitate work.

摘要： PURPOSE:To improve preciseness in internal pressure control and to improve safety, by controlling the pressure in a closed vessel used for under water welding machine etc. with a gas-feed hose equipped with an exhaust gas valve which is always closed and with a gas feed control valve. CONSTITUTION:When water press. C due to submergence of a underwater welding machine is exerted on the diaphragm 20 of a press. detector 18 installed on a watertight vessel 4, a dock 26A for a rod 22 operates a limit switch 25A to excite the solenoid 19a of an electromagnetic valve 19A, and internal-pressure-controlling gas 3a is led into the vessel 4. When the pressure in the vessel 4 exceeds the power of the spring 23, a dock 26B operates a limit switch 25B and stops exciting the solenoid 19a so that supply of the gas 3a is ceased. Consumption of the controlling gas 3a causes to starts the supply of the gas 3a once again. When the underwater machine surfaces, a dock 26C operates a limit switch 25C because the outer pressure C lowers, and the solenoid 19b of an electromagnet valve 19B is excited and excess gas 4b in the vessel 4 is released through a hose 13 for feeding the internal-pressure- controlling gas.
