Canted coil spring rings each with a first plurality of coils having first coil major and minor axes; a second plurality of coils each having second coil major and minor axes; the coils of the first plurality of coils alternating with the coils of the second plurality of coils according to an alternating pattern. The spring rings having inner and outer perimeters and wherein the inner perimeter of the spring ring is defined by at least said first plurality of coils. The resulting configuration of the spring ring has improved spacing along the inner perimeter, among others, with respect to a similar canted coil spring ring having a constant coil cross section, such as a coil length with all similar coils.

The present invention is an air shock absorber having a multiple stage design. The design includes a first algorithm for determining the compressed and extended lengths of the air shock based on the lengths of the parts for each stage. The first algorithm offers the air shock an extended length that is greater than twice its compressed length, an optimized extended length, and a construction capability based on adding stages. In particular, the extended length-compressed length relationship is a quality inherently unobtainable by current shock absorbers. The design also includes a second algorithm for determining the spring rate. The second algorithm offers the capability to both set-up the air shock with a relatively linear spring rate and make the relatively linear spring rate more linear.

A diaphragm transfer device sucks and transfers a diaphragm that includes a first protrusion protruding in a direction perpendicular to the surface of the diaphragm. The diaphragm transfer device is provided with: a placing table on which the diaphragm is placed in such an orientation that the first protrusion faces downward; and a suction pad that sucks the diaphragm, placed on the placing table, from above on the outer circumferential side of the protrusion. The placing table includes an annular pedestal facing an outer-circumferential-side thick portion of the diaphragm, the thick portion being sucked by the suction pad, and a second recess recessed downward on the inner diameter side of the pedestal. The whole first protrusion of the diaphragm is located inside the second recess in a top view.
