Latest Patents

Fukuda's latest patents include a fuel cell and a seat belt retractor with a tension eliminator. The fuel cell patent describes a system that incorporates an electric-power generator, a fuel distribution mechanism, and a pump. The electric-power generator features a membrane electrode assembly that includes an anode, a cathode, and an electrolytic membrane. The fuel distribution mechanism consists of a container with a fuel discharge surface, housing the electric-power generator, and a thin tube that connects the fuel outlet and inlet. The pump is directly connected to the fuel inlet, ensuring efficient fuel management.

The seat belt retractor with a tension eliminator is designed to enhance safety in vehicles. It features a ratchet wheel arrangement that acts as a position memory when the buckle switch is closed. This mechanism responds to the belt webbing being drawn off the reel by a seat occupant leaning forward beyond a predetermined distance. The internal gear arrangement allows the wheel to rotate proportionally to the excess distance, enabling the webbing to retract only a predetermined distance. This design effectively eliminates slack in the webbing when the occupant returns to their original position.
