摘要： PURPOSE:To supply a suitable quantity of fuel exhaust gas to a reformer and effectively utilize extra energy even in the case of switching to operation by methanol. CONSTITUTION:In general, a reformer 10 reforms city gas introduced through a city gas supply line 2a. The reformed gas obtained by reformation is supplied to a fuel cell main body 12 through a cell supply line 11 for the purpose of power generation. Methanol vapor which is vaporized by a methanol vaporizer 22 for storing methanol liquid when city gas is cut off is supplied to the reformer 10. Fuel exhaust gas where a part of hydrogen is consumed by a hydrogen electrode 13 of the fuel cell main body 12 flows in a burner line 14 and a fuel exhaust gas line 28a connected to the city gas supply line 2a. An orifice 29 capable of controlling a flow rate, a fuel exhaust gas supply valve 30 which is switched from the fully closed state to a fully opened state, and a blower 31 are provided in the fuel exhaust gas line 28a.

摘要： PURPOSE:To detect the relief amount of a running robot and to achieve safety in working by bringing a detecting shaft into contact with a surface on which a wheel runs, and detecting the movement in the direction of the detecting shaft with a detecting device. CONSTITUTION:A relief detecting shaft 5 is inserted into two bearings 6a and 6b which are fixed to a wheel part 3. A spring 7 is coupled with the lower part of the bearing 6b of the shaft 5. The spring 7 is held with a spherical caster 8. A rack 9 is formed at the shaft 5 on the upper side of the bearing 6a. The rack 9 and a pinion 10 which is fixed to the shaft of a potentiometer 11 are engaged. The potentiometer 11 is fixed to an attaching stage 13 of the wheel part 3 through a fixing stage 12. In this constitution, the amount of up and down movement of the shaft 5 is transmitted to the potentiometer 11 through the pinion 10 and can be detected as digital values. Therefore, accidents such as the breakdown of the working robot and the flaws in the wall of a pipe can be prevented.

摘要： PURPOSE:To enable automatic grinding under constant pressure, by engaging a driving gear fitted on the drive shaft of a motor, with a driven gear fitted on a rotary shaft, and by coupling the rotary shaft and the drive shaft to each other through a link, and providing a spring between the link and a case at the side of the drive shaft. CONSTITUTION:When a ground surface 24 has a projection 25, a grindstone 15 comes into contact with the projection so as to ascend to compress a spring 19. As a result, pushing torque Ts increases so that the rotation of the grindstone 15 is retarded. For that reason, a link 16 is turned counterclockwise so that the spring 19 is compressed further. Consequently, the grindstone 15 goes up from the ground surface 24 so that a pushing force Fp decreases. Because of the decrease in the pushing force Fp, the spring 19 acts to turn the link 16 clockwise to increase the pushing force. In other words, if the height of the projection 25 is large, the increase in the pushing torque Ts is absorbed by a differential mechanism including the link 16, so that the grindstone 15 comes into contact with the ground surface 24 under constant pressure, regardless of the height of the projection 25.

摘要： PROBLEM TO BE SOLVED: To prevent the heat dissipation of a fuel cell stack and miniaturize the stack. SOLUTION: This fuel cell has a manifold formed of an inside member 9 facing a fuel cell stack side surface, an outside member 10 not facing the fuel cell stack side surface, and a hollow part 11 enclosed and formed by the inside member 9 and the outside member 10 and internally vacuumed. The heat dissipation of the fuel cell stack 1 is transferred to the inside member 9 of the manifold, and the transfer of the heat is arrested by the vacuumed hollow part 11. Thus, the heat dissipation of the fuel cell stack is never transferred to the outside member 10, whereby heat isolating effect can be provided.

摘要： PURPOSE:To prevent adhesion between a unit cell and a separator without decrease in electric conductivity between them and easily replace a defective cell without breakage of a normal cell by installing a conductive-water repellent layer between the unit cell and the separator. CONSTITUTION:As a conductive-water repellent material with heat resistance and phosphoric acid resistance, graphite, carbon, wolfram, tantalum, or a carbide of them is used and as a material lacking in only conductivity, graphite fluoride only or its composite is used. When a composite of a conductive material and a water repellent material is used, its mixing ratio is important, and the thickness of a conductive-water repellent material layer 3 is limited to several Lens mum to several hundreds mum. The layer 13 is formed on a separator 13 or a unit cell 5 in a powder pressing process, coating and baking process of powder dispersed in a solvent, or a process interposing between sheets previously formed. Visco-elastic adhesion producing between the separator 3 and carbon fibers of the unit cell 5 or adhesion caused by sticking of silica pyrophosphate is prevented.

摘要： PURPOSE:To detect easily a distance up to a subject to be measured by forming the image of a reflected light beam available from irradiating the subject to be measured by a light source fitted on a case on the light receiving element of a case bottom by means of a reflecting mirror and a movable lens and obtaining the position where the lens moves. CONSTITUTION:The laser beam source 2 is fitted outside the bottom plate 1a of the case 1 to irradiate the subject to be measured 3. A motor 4 is fitted inside the case 1, and a threaded-rod 7 turning through an output spindle 4a and gears 5 and 6 is fitted on the case 1 in the longitudinal direction. A moving frame 8, which advances and retreats due to the turn of the threaded-rod 7, is fitted on a moving frame 8. The reflecting mirror 8c fitted obliquely on the opening of the frame 8 projects the irregularly reflected light beam from the subject to be measured 3 on the light receiving element 9 at the bottom of the frame 8 through a lens 11. A controller 16 detects the output of the light receiving element 9, drives motors 4 and 14 and condenses light beams. It obtains a distance from an interface between the lens 11 at that time and the light receiving element 9 and the subject to be measured 3. Thus optical axis matching and focusing are executed simultaneously, and measurement can be easily carried out at high accuracy.

摘要： PROBLEM TO BE SOLVED: To improve the heat resistance, corrosion resistance, water repellency, and electric insulation of the sealing part between a gas manifold, a cell stack, and a fastening plate, by providing a specific protective layer between the side surface of the cell stack and a sealing material adjoining the side surface. SOLUTION: This fuel cell 11 is equipped with: a cell stack 7 constituted by laminating plural sub-cell stacks 3 on which plural unit batteries 2 are laminated, and a gas manifold 8 arranged in the side surface of the cell stack 7 via sealing materials 9a and 9b, to supply a reaction gas to a unit battery 2, and also exhausting an exhaust body (drain, etc.). As an improved point, a protective layer (protective sheets 13a and 13b), having heat resistance, corrosion resistance, water repellency, and electric insulation, is interposed between the side surface of the cell stack 7 and the sealing materials 9a and 9b. This can prevent an electric short circuit due to liquid containing phosphoric acid, etc., between the gas manifold 8, the cell stack 7, and fastening plates 12a and 12b.
