A metal separatorfor a fuel cell is configured such that, after forming through-holesandon a first separator memberand a second separator member, rising wall sectionsandare provided so as to be spaced apart from formed sectionsandfor introducing a gas by a predetermined distance L, the rising wall sectionof the first separator memberis fittingly inserted into the rising wall sectionof the second separator memberfor performing a positional alignment therebeween, and then, the rising wall sectionsandare folded to be caulked, whereby the first separator memberand the second separator memberare bonded to each other. A positional alignment between the first separator memberand the second separator memberbecome facilitative.

By using a hydraulic forming device, a metal plate bodyis placed on a support sectionwith a hollow sectionformed on a lower diefilled with hydraulic fluid A. Subsequently, a blank holderis lowered to clamp the peripheral edge section of the placed metal plate bodywith the support section. Then, the upper dieis lowered relative to the lower dieto pressedly deform the central section of the metal plate bodyand to compress the hydraulic fluid A to increase the fluid pressure. A rib-like convex sectionis transferred onto the metal plate bodyby the increased fluid pressure of the hydraulic fluid A and a formed section. Further, the fluid pressure of the hydraulic fluid A is kept for a predetermined time. Then, the increased fluid pressure of the hydraulic fluid A is released.

A fuel cell composed of a plurality of cell function assemblies of each of which includes a set of spaced electrolytic membranes, two pairs of electrode plates in contact with opposite surfaces of each of the electrolytic membranes, a set of separators, and a set of six support frames assembled to retain the electrolytic membranes and separators in position. In the fuel cell, the separators each are in the form of a flat plate of synthetic resin integrally provided with a plurality of spaced projections made of pressed carbon powder and retained in contact with the electrode plates to form a pair of reaction chambers at opposite sides of each of the electrolytic membranes.

When power is output from an engine 50 to a crankshaft 56, a multiplying gear unit 57 attached to the crankshaft 56 increases a revolving speed but decreases a torque and transmits the increased revolving speed and the decreased torque to a rotating shaft 57e. A drive shaft 22 of a vehicle that cruises at a constant speed is generally driven at a higher revolving speed and a smaller torque than a driving point at which the engine 50 is driven with a high efficiency. The multiplying gear unit 57 converts the power output from the engine 50 to a power of high revolving speed and low torque. This structure decreases the amount of electrical energy transmitted between a clutch motor 30 and an assist motor 40 in the process of torque conversion by the clutch motor 30 and the assist motor 40 and thereby reduces an energy loss of both the motors 30 and 40. This effectively reduces the required capacities and size of the clutch motor 30 and the assist motor 40.

A MacPherson strut type automotive suspension system having an attaching portion to a body of an automobile. This attaching portion includes an inner cylindrical member secured to a piston rod in a shock absorber, an outer cylindrical member disposed in coaxial relation to the inner cylindrical member and secured to the body of an automobile, and a cylindrical resilient member interposed between the both inner and outer cylindrical members. A stopper is secured to the inner cylindrical member and adapted to abut the bottom surface of the cylindrical resilient member, thereby preventing an excessive displacement of the resilient member in its axial direction.

Automotive suspension system

Disclosed is a wheel camber adjusting means for use with strut type suspension means for vehicles wherein a pair of arms of a bracket mounted on the lower end of a shock absorber strut are overlapped upon one end of a knuckle arm connected at the other end to a tip end portion of a lower arm through a ball joint. The pair of arms are pivotally connected to the knuckle arm by means of at least a connecting bolt arranged substantially in the longitudinal direction of the vehicle. The bracket is connected to the knuckle arm at a position vertically spaced from the connecting bolt by means of an adjusting bolt arranged in substantially the lateral direction of the vehicle.
