摘要： PURPOSE:To improve the response to the sharp increase in load, by using DC power generated by a fuel cell, to electrolyze an electrolyte to produce hydrogen gas and oxygen gas to store them, and by supplying the stored gas to the fuel cell at the time of the sharp increase in the load. CONSTITUTION:A fuel feeder 18 is connected to the DC power output section of the body 1 of a fuel cell to electrolyze an electrolyte stored in the fuel feeder and made of a solution of sodium hydroxide or the like. Hydrogen gas and oxygen gas are produced by the electrolysis and sent to a hydrogen and an oxygen gas feed lines for the body 1 of the fuel cell. When the load as to electric power has sharply increased, solenoid values 22a, 22b are controlled to be open for a prescribed time so that the hydrogen gas and the oxygen gas pressurized in gas storage pipes 21a, 21b by an accumulator 24 are quickly supplied to the hydrogen and the oxygen gas feed lines for the fuel cell body 1. After the prescribed time, the supply of the hydrogen gas and the oxygen gas to the feed lines is terminated.

摘要： PURPOSE: To prevent a threaded part from breaking due to fatigue, by dispersing bending moment, which acts on a moving blade shaft, to be prevented from being transmitted to the threaded part of the moving blade shaft, by means of a pair of concentric ring-shaped tightening members having a tapered surface aligned and brought into contact with each other.
CONSTITUTION: A hub fitted to a rotary shaft provides in a rim part 24A a moving blade-shaft insertion hole 25 extending in a radial direction. A moving blade shaft 27 is inserted into this insertion hole 25. And the moving blade shaft 27, protruded to a reverse part 24B of the rim part 24A, forms a smooth round bar part 27B and a threaded part 27C successively with a step difference. The round bar part 27B assembles a pair of concentric ring-shaped tightening members 22, 23 having a tapered surface reducing its contour toward the point end part of a moving blade. And the moving blade is tightened by a tightening nut 28. The tightening members 22, 23 are constituted so as to tighten the moving blade by the wedge action in accordance with a level of centrifugal force acting on the moving blade.

摘要： PURPOSE:To prevent the reduction of the fatigue strength of a screw part by installing a holding member for holding a movable-vane shaft between a thrust bearing and a fastening nut and allowing only the lightened centrifugal force to act onto the screw part of the movable-vane shaft having the fastening-nut arranged. CONSTITUTION:A ring 60 is shrink-fitted onto a straight frictional fastening part 27C formed in the shaft part 27 of a movable vane, and a fastening nut 34 is arranged in a screw part 27D, and the ring 60 is fastened onto a thrust bearing 30. Since the movable-vane shaft part 27 is certainly fixed in the radial direction of the shaft part in the straight frictional fastening part 27C through the shrink-fit ring 60, the bending moment generated on the movable vane is transmitted to the thrust bearing 30 through the shrink-fit ring 60, and the bending moment transmitted to the screw part 27D becomes little, and further a part of the centrifugal force is born by the contact surface between the straight frictional fastening part 27C and the shrink-fit ring 60, and therefore, also a part of the centrifugal force acting onto the screw part 27D is lightened, and the reduction of the fatigue strength of the screw part 27D can be prevented.

摘要： PURPOSE:To cool a rotary shaft passing through a device wall, by mounting a cylindrical radiant heat shielding plate to a low temperature portion outside the device wall in such a manner as to be located in the vicnity of a device wall passing portion of the rotary shaft, and flowing a cooling fluid in a space defined by the shielding plate and the rotary shaft. CONSTITUTION:A cylindrical radiant heat shielding plate 8 is so provided as to be located in the vicinity of a furnace wall passing portion of a rotary shaft 2. The shielding plate 8 is mounted through a heat insulating material 8 to a support 4 outside a furnace wall 1. A cooling fluid supplied from a cooling fluid supply hole 5a is flown in a space C defined by the shielding plate 8 and the rotary shaft 2. With this arrangement, radiant heat D in the space C from the support 4 is hindered by the radiant heat shielding plate 8 which is thermally shielded from the support 4 by the heat insulating material 9, and is prevented from being transmitted to the rotary shaft 2.

摘要： PURPOSE:To enable the size of a shift converter to be reduced by constituting it of a mono-block isothermal reactor consisting of a reaction part and an evaporating cooler surrounding the reaction part. CONSTITUTION:One end of the reaction tube 3A of a shift converter 3 is connected to the outlet of a cooler 2 and the other end is connected to the inlet of another cooler 4. The reaction tube 3A has a meander section packed with a catalyst which can react with gas fed from a reformer 1. The gas introduced into the shift converter 3 reacts with the catalyst while passing in the reaction tube 3A. The heat produced during the reaction is transferred to water (W) existing around the reaction tube 3A to produce steam. Owing to the above constitution, the shift converter 3 is made compact. In addition, reaction temperature can be maintained constant regardless of the magnitude of the load thereby achieving a stable reaction.

摘要： PURPOSE:To aim at the promotion of low-unit cost of production and simultaneously promote improvements in reliability on assembling work in addition to responsiveness in a feedback system, by installing a servo device in the fan machine inside, while incorporating both electrical control and feedback mechanisms. CONSTITUTION:A pressure oil leading device 7 is installed in the end part of a shaft 3, while an electro-hydraulic servo valve 21 is attached to the side of the device 7 via a distant piece 20 provided with feed and drain oil holes. A control signal is fed to this servo valve 21, then a controller 22 to operate upon receiving a feedback signal from a displacement indicator 24 is set up outside a fan machine, and connected by each of electric cords 25 and 26. Motion in a cylinder 5, making the angle of a rotor blade 1 variable, is transmitted to an iron core 23 attached to a feedback bearing 14 and fed back to the controller 22 by the displacement indicator 24 as an electric signal. With suchlike constitution, the number of parts items and parts cost both are reduced so that both of reliability on assembling work and responsiveness in a feedback system are well improved.
