Abstract: A fuel cell ship includes a fuel cell compartment in which a fuel cell is installed, a tank compartment in which a fuel tank is installed, a fuel supply pipe through which fuel is supplied from the fuel tank to the fuel cell, and a control unit. The fuel supply pipe includes at least two shutoff valves. Fuel gas detectors that detect a fuel gas being in a gaseous state of the fuel are each installed in the compartments. If at least one of the fuel gas detectors detects that a concentration of the fuel gas is equal to or greater than a predetermined standard value, the control unit controls to close a shutoff valve in a compartment out of the tank compartment and the fuel cell compartment, where the fuel gas detector having detected the concentration equal to or greater than the standard value is installed.

Abstract: An exemplary fuel cell ship is a fuel cell ship for propelling a hull by using electric power supplied from a fuel cell that generates electric power through an electrochemical reaction of fuel, and includes a compartment including an emission source of the fuel and a first detector arranged in the compartment to detect the fuel. If the first detector detects that a concentration of the fuel in the compartment is equal to or greater than a first threshold value, a power supply to a non-explosion-proof device in the compartment is stopped.

Abstract: A support beam includes a first supporting portion, a second supporting portion, and an arm connecting the first supporting portion to the second supporting portion. The arm includes a web and a flange. The flange includes a first end, a second end, and a center portion. The center portion of the flange is connected to an end of the web. The flange includes bent portions at which the center line of the thickness of the flange is bent outward in the extending direction of the web in the region between the first end and the second end in a transverse cross section of the arm.

Abstract: An audio playback device includes an interruption-information storage memory which holds frame information at the time of an interruption of playback, a compressed-stream control section which calculates a start position of reading the compressed stream from a recording medium, and reads the compressed stream accordingly, a compressed-stream decode section which decodes the compressed audio stream and transmits decoding information on the frame to the compressed-stream control section as additional resume information, and an output control section which outputs a decoding result. When playback is restarted after an interruption, playback can be restarted without any section not played back in terms of time and without any frequency range not played back, by calculating the start position of reading the compressed stream based on both the additional resume information and the frame information at the time of the interruption, and by reading the compressed stream accordingly.
