PROBLEM TO BE SOLVED: To effectively prevent the induction of thermal runaway between battery modules disposed adjacent to each other, effectively prevent thermal runaway caused by heating from the exterior, and unfailingly prevent the induction of the thermal runaway over a long period while making an outer shape compact.SOLUTION: In a power source device, multiple battery modules 1 are disposed adjacent to each other. Each battery module 1 includes multiple chargeable batteries and a fire resistant heat insulation case 2 which houses the batteries, is closed, and is not hermetically sealed. The fire resistant heat insulation case 2 has a lamination structure of metal plates 3 and heat insulation plates 4 that is formed by laminating the heat insulation plates 4 on inner surfaces or outer surfaces of the metal plates 3 and shields fire and heat with the metal plates 3 and the heat insulation plates 4.

PROBLEM TO BE SOLVED: To provide an oil cleaning apparatus and an oil cleaning method which achieve long life of a precision filter.SOLUTION: The oil cleaning apparatus includes: a centrifugal separator; the precision filter; a main tank which stores oil to be cleaned; piping which connects at least among the centrifugal separator, the precision filter and the main tank; a supply pump provided in the piping; a stop valve provided in the piping; and a control part which controls operation of the supply pump and the stop valve. The control part controls operation of the supply pump and the stop valve in order to perform a first cleaning stage to clean the oil in the main tank only by the centrifugal separator and to return it to the main tank. After the first cleaning stage, the control part controls the operation of the supply pump and the stop valve in order to perform a second cleaning stage to clean the oil in the main tank only by the precision filter and to return it to the main tank. After the second cleaning stage, the control part controls the operation of the supply pump and the stop valve in order to perform a third cleaning stage to clean the oil in the main tank by the centrifugal separator and then by the precision filter in succession and to return it to the main tank.

PROBLEM TO BE SOLVED: To provide a bubble type liquid level gauge which is simply constructed by using a sounding pipe and general service air, and allows easy portability and efficient cargo handling. SOLUTION: The liquid level gauge has: an air supply pipe 5 into which compressed air is supplied; a pressure sensor for measuring a pressure in the air supply pipe 5; and a display part 20 displaying a liquid level in a tank, based on a detection signal of the pressure sensor. The air supply pipe 5 is portable and windable, inserted into a sounding pipe 6 hanging within a tank from upside of the tank; a general service air pipe 3 installed in a ship is used as a compressed air supply source; the general service air pipe 3 and the air supply pipe 5 are connected by having an attachable part 21 with the general service air pipe 3 and an attachable part 22 with the air supply pipe 5; and a portable detector body 1 equipped with the pressure sensor and the display part 20 displaying a liquid level in the tank based on a detection output of the pressure sensor is provided.

PROBLEM TO BE SOLVED: To provide a propulsion device for a ship and a ship equipped with the same, improving the efficiency of a propeller and a working property, and reducing weight, as compared with a propulsion device for a ship using a propeller boss cap with a fin of a conventional technology and a ship equipped with the same, in the propulsion device for the ship formed of a screw propeller using the propeller boss cap with the fin and the ship equipped with the same. SOLUTION: In the propulsion device for the ship wherein the fin 6 provided at the propeller boss cap 5A is disposed in the rear side between propeller blades, the rear end 5a of the propeller boss cap 5A is formed on an end surface, or the shape of the rear end 5a is made to be within a range of 20% of the total length Lc from a peripheral edge to the propeller boss cap 5A. The total length Lc is made to be 0.28-0.76 times of a diameter Dcf of a cap front end, and the diameter Dca of the rear end 5a of the propeller boss cap 5A is made to be 0.35-0.95 times of the diameter Dcf of a front end 5f of the propeller boss cap 5A.
