Abstract: A clutch assembly having an overall diameter and overall axial length. Both the axial length and the ratio of the length to the diameter are reduced. A translatable clutch piston is in communication with a pressure chamber and is movable between a piston neutral position and a piston activated position in response to air pressure. A cone clutch member is moved from a clutch engaged position to a clutch disengaged position in response to the translatable clutch piston moving from the piston neutral position to the piston activated position. The cone clutch member engages the rotating drive shaft when in the clutch engaged position. A clutch spring member biases the cone clutch member into the clutch engaged position with a clutch engagement force. The clutch spring has a primary spring ratio of a wire diameter to a spring diameter optimized such that a maximum spring force is achieved while minimizing the spring length.

Abstract: A foldable boarding ramp is operatively connected to a door opening provided in a body and is selectively extendable to the ground. The foldable boarding ramp is stored in a folded state inside a fairing covering a connecting portion between the body and a main wing. Thus, a reduction in the space of a passenger compartment and a cargo compartment due to the storage of the folded boarding ramp is prevented. In addition, an increase in air resistance can be suppressed without providing a dedicated fairing for covering the boarding ramp. Further, an interlocking member connects together a door for opening and closing the door opening and the boarding ramp when the door is opened. The boarding ramp may be automatically deployed to improve convenience.

Abstract: A clutch unit according to the present invention includes a driving sleeve fixed to a driving shaft and a driven sleeve fixed to a driven shaft. A coil-like clutch spring is received on the driven sleeve, and a clutch sleeve is received on the driving sleeve. When the driving shaft is rotated normally or reversely, the driving sleeve abuts one of the arm portions of the clutch spring. Consequently, the clutch spring engages the driven sleeve. Torque producing rotation in either direction is transmitted to the driven shaft. The clutch unit also can operate as an overrunning clutch. When the clutch unit is adapted to a film feeding and driving system in a camera, the clutch unit can be positioned to utilize what had been dead spaces in a camera body, thus promoting compact camera design.
