Abstract: PURPOSE: To allow the easy detachment of exchangers from a holding mechanism so as to facilitate the exchange of the exchangers and to assure the unexpectedness and fan of movement by moving a magnet of a holding mechanism to attract and detach the spherical body parts of the exchangers in proximity to a spherical ball receiving part. CONSTITUTION: A magnet part 30 is constituted by attracting yokes 32a, 32b from before and behind the magnet 31. The upper part of the magnet part 30 is provided with a shaft part 33 faced upward. The shaft part is supported freely turnably on a horizontal plane. Paired spherical ball receiving parts 40A, 40B are composed from parallel supporting pieces 42 formed with recessed parts 41 to receive the spherical ball parts 24 of arm parts 22a, 22b. Further, the spherical ball receiving part 40C is composed of the parallel supporting pieces 42 formed with the recessed parts 41 to receive the spherical ball parts 24 of leg parts 23a, 23b.  The yokes 32a, 32b and the supporting pieces 42 are parted when the magnet part 30 turns perpendicularly from an attraction position P1 and, therefore, the magnetization of the respective spherical ball receiving parts 40A to 40C is eliminated and a detached state is attained. Then, the exchange of the exchangers 22, 23 is facilitated and the unexpectedness and fan of movement are assured.

In this case, the 1st bar lens is telecentric on image field side and the 2nd bar lens 2 is telecentric on object field side. Hence, the face on the image field side of the former and the face on the object field side of the latter act as if to form an air lens and also act as a field lens, thus if image heights are taken at the axis of abscissa, and light intensities on image plane at the axis of ordinate, they show a Gaussian distribution. These bar lenses may be so made at to enable their setting in a grooved block 12 to be independently made by using an intermediate ring 6'.

The bias layer 7 is made of fiber-reinforced resin layer comprising reinforcing fiber with 200-400 GPa of tensile elasticity and is formed by winding two bias prepreg sheets several times around a mandrel. On the other hand, the straight layer 6 is constituted of a fiber reinforced resin layer comprising reinforcing fiber with tensile elasticity lower than 60 GPa and is similarly formed by winding two straight prepreg sheets. As the reinforcing fiber with tensile elasticity within the range 200-400 GPa, carbon fiber is most preferable since it is light.

IPC: H01M8/24
Filed: 1982-05-25
Abstract: PURPOSE:To equalize the temperature distribution of the entire cell stack so as to realize a stabilized characteristic of an air-cooled fuel cell by preventing any rise or drop of the temperature of unit cells located in the ends of the cell stack by locating a carbonaceous auxiliary cooling plate having air paths between a gas- separating plate and a terminal plate which are located in the outermost end of the cell stack.
