A structure for reducing impact force due to the collision of a movable iron core (4) against a fixed iron core (3), especially, impact force exerted against a bottom plate of a lower casing (2) where electromagnetic contactor mounting portions are provided. A back portion of the fixed iron core (3) is put on the botto...
In a solid electrolyte fuel cell [1,2,3], reactant gases are directed by the reactant gas distributing means [11A,11B] to flow radially between its central [5,6] and peripheral portions [14] and this obviates the need to provide an overall gas seal between the individual components of the fuel cell. A gas seal, if nece...
A contact device includes a housing, a fixed contact (14a), and a moving contact (15a) attached to a support frame (13), the support frame and moving contact movable within the housing perpendicular to the fixed contact. A stopping (18) arm projects from the support frame to restrict movement of the support frame withi...
Phthalonitrile, an alkali metal or an alkali metal compound, and a hydrogen donor compound are heated in an organic solvent to synthesize a partially hydrogenated alkali metal phthalocyanine, which is then brought into contact with a dealkalizing agent to effect substitution with hydrogen of the partially hydrogenated ...
