摘要:
A noise eliminator for a fuel cell, where an outer shell has a reception section in which a sound absorption material is placed between the outer shell and an inner pipe and has a water discharge section that is positioned so as to face a lower portion in the vertical direction of the inner pipe and in which the sound absorption material is not placed between the outer shell and the inner pipe. The water discharge section receives water flowing into the outer shell and allows the water to flow to the outside of the outer shell. Although the water discharge section receives water flowing into the outer shell, the sound absorption material inside the noise eliminator does not absorb the water from the water discharge section and does not contain it because there is no sound absorption material in the water discharge section.
摘要:
A noise eliminator for a fuel cell installed in an exhaust system discharging exhaust gas from the fuel cell, comprising an inner pipe having a plurality of sound transmission holes formed in its peripheral wall and allowing the exhaust gases to flow therethrough and an outer shell disposed to surround the inner pipe through a prescribed distance from the peripheral wall and constituting a sound absorbing chamber with a sound absorbing material filled in the clearance thereof from the inner pipe. The sound transmission hole has an inner diameter of 3 mm or greater, and a depth of 1.2 mm or less.

摘要:
A noise eliminator for a fuel cell has a noise elimination chamber that is filled with a noise elimination material, and also has discharge gas flow piping penetrating the noise elimination chamber and having holes in the peripheral wall of the piping and through which gas charged from the fuel cell flows. An electrically conductive material is added to the noise elimination material. The construction suppresses electrostatic charging even if discharge gas flows in the discharge gas flow piping.
摘要:
To provide a high-speed paper-feeding device for feeding slips or papers from the hopper by using a pick roller, featuring reduced misoperation, reduced noise, a higher paper-feeding speed and compactness. In the high-speed paper-feeding device, the bouncing motion of the pick roller that may take place at the beginning of the paper-feeding operation is suppressed by using a buffer device, the end portions only of the slips or the papers are pushed up/restored by a push-up device, that moves the arm up and down being driven by a solenoid that is provided at the bottom of the hopper, in order to reduce the burden for moving the hopper up and down born by the motor and the rack-and-pinion mechanism. Besides, the motion of the pick roller is detected at a moment when the rear end of the slip separates away from the pick roller to control the continuous feeding of the papers while eliminating dead time between the papers that are fed and enabling the papers to be continuously fed at high speed.
