  • Separator for fuel cell and fuel cell stack
    Patent number: 11784324
    Abstract: A separator for a fuel cell is overlapped with a membrane electrode assembly to form a stack unit of a power generation cell stack body. The separator is provided with a positioning section to be overlapped in the stacking direction in a manner that the stack units are positioned with respect to each other. A marginal portion of the positioning section has a bent surface formed by bending the separator.
    Type: Grant

  • Synchronizing system and transmission torque control device therefor
    Patent number: 6536572
    Abstract: There are provided a synchronizing system which synchronizes two relatively rotating rotary bodies with each other by frictional forces generated between friction discs, such that a larger torque can be transmitted between the rotary bodies as an input torque becomes larger, and a transmission torque control device for the synchronizing system. In order to transmit torque between an input shaft and a gear member, the synchronizing system which connects the input shaft and the gear member with each other while synchronizing them urges a blocking ring toward the gear member by using a synchronizing spring, when a sleeve is caused to slide toward the blocking ring by an actuator.
