Patent JP-H01166471-A (JP)
Title: Fuel cell power generation system
Inventor: TAKAGI YASUO
IPC: H01M8/06
Filed: 1987-12-23
Abstract: PURPOSE:To make it possible to enhance quality improvement rate and to set an anode pressure irrespective of the pressure of a quality improver by making the quality improver practically independent of an arrangement by the presence of a vapor remover and a fuel gas pressurizing means thereby reducing the pressure in a reaction tube of the quality improver. CONSTITUTION:Since a vapor remover 31 and a compressor 32 are interposed between a shift converter 14 and an anode A of a fuel cell body 1 in an arrangement, no inconvenience is caused even if an anode pressure P2 is set to a pressure far higher than the pressure of a quality improver. Namely, the quality improver can be practically separated from the arrangement. As a result, it is possible not only to enhance fuel quality improvement rate by always keeping the quality improver pressure low but also to supply enough amount of water vapor to the quality improver 13 even when a temperature control line pressure P5 lowers during a heavy load period. Since the anode pressure P2 is not affected with the quality improver pressure, a turbine inlet pressure P3 is not affected with the quality improver, and gas pressure control of the anode A and a cathode K becomes easier.

Title: Slip mechanism
Inventor: SHIMOMURA SATOSHI
IPC: F16H55/17
Filed: 1990-11-28
Abstract: PURPOSE:To simplify the assemblage of a slip mechanism by pressing a first abutting surface of a peripheral wall surface of a boss hole in a gear against a first slide surface of the outer peripheral surface of a gear boss and a second abutting surface of the side face of the gear against a second slide surface of a receiving member of the gear boss and providing a locking section. CONSTITUTION:A spindle 1 and a gear boss 2 are united with each other, and the gear boss 2 is inserted from the guide surface 12 side into a boss hole 20. Then, an elastic contact piece 22 is radially expanded by the guide surface 12 to facilitate the insertion of the gear boss. Next, the gear boss 2 is inserted into the boss hole 20 until a first abutting surface 23 is pressed against a first slide surface 11 and a second abutting surface 28 is pressed against a second slide surface 15. Then, a locking claw 26 engages a locking part 13 through the elastic contact piece 22. When one of the gear boss 2 or a gear 5 is pivoted, a pivotal force is transmitted to the other of the boss 2 or the gear 5 by a frictional force between the first abutting surface 23 and first slide surface 11 and between the second abutting surface 28 and second slide surface 15 to pivot integrally both boss and gear. When the pivotal force is larger than the frictional force between both press contact parts, slips are generated in the press contact parts respectively to prevent an superfluous pivotal force from transmission from one to the other.
