An energy harnessing device for harnessing wave energy that results in pitch, sway, yaw, surge, roll, and heave movement, wherein the device effectively converts multiaxial translational and rotational motion to unidirectional rotational motion for power transmission.

This extensible/contractible driving device includes a rotatable driving member configured to be rotated by drive force of a driving unit; a drive force-transmitting member connected to a leading end of the internal cylinder, configured to be driven by the rotatable driving member so as to move along a rotary shaft direction of the rotatable driving member; and an elastic member disposed in the periphery of the drive force-transmitting member, connected to the leading end of the internal cylinder, and configured to apply biasing force in the rotary shaft direction to the drive force-transmitting member. The rotatable driving member, the drive force-transmitting member, and the elastic member include an intervening member (24) stored in an inner space between external and internal cylinders, disposed in the periphery of the internal cylinder, and intervening between the internal cylinder and the external cylinder. The intervening member (24) includes a plurality of component parts (31a, 31b) having a length in a longitudinal direction of the external cylinder. One of the component parts (31a) is displaced relatively with respect to the other component part (31b) so that the intervening member (24) is opened widely outward. Accordingly, it is possible to suppress a problem of slidability caused by distortion in shape of the intervening member (24) and a problem of interference among the composing members.

A geared motor includes a stopper mechanism restricting the range of movement when the trailing gear rotates in a counter-clockwise direction. In the stopper mechanism, a first and a second angle ranges are obtained by dividing the range of angle of rotation of the trailing side gear by a virtual line passing through the center of rotation of the trailing side gear and the center of rotation of the driving side gear. In the first angle range in which the stopper touching part moves in a direction approaching the center of rotation of the driving side gear when the trailing side gear rotates in a counter-clockwise direction, the stopper touching part touches the part to be touched by the stopper. Thus, when the stopper mechanism is activated, the trailing side gear is subjected to a reaction force in a direction away from the driving side gear, making the meshing shallower.

The geared motor and pointer device are provided with a stopper mechanism which restricts the range of movement of the trailing-side gear when the trailing-side gear rotates in a counter-clockwise direction. In the stopper mechanism, the part to be touched by the stopper comprises a support-side protrusion which protrudes towards the center of rotation of the trailing-side gear, and the width dimension in the peripheral direction of the support-side protrusion is smaller on the inside in the radial direction than on the outside in the radial direction. As a consequence, even if the width in the peripheral direction of the support-side protrusion is increased to a certain extent in order to ensure strength, when the stopper mechanism is activated, the stopper touching part and the part to be touched by the stopper come into contact at a position close to the center of rotation of the trailing-side gear.

The present system for fall restraint includes a mounting frame connected to a trigger mechanism and firing blocks, with a trigger cable extending through apertures in the mounting frame and trigger mechanism. Sudden movement by a user, such as a fall, actuates the trigger mechanism to trigger the firing blocks. The firing blocks are loaded with anchors and firing cartridges. Triggering the firing blocks causes the cartridges to fire, propelling the anchors into an anchoring surface, such as a roof. Because the user is connected to the trigger cable, once the anchors deploy the user is anchored to the roof and their fall arrested.

A Stirling cycle machine. The machine includes at least one rocking drive mechanism which includes: a rocking beam having a rocker pivot, at least one cylinder and at least one piston. The piston is housed within a respective cylinder and is capable of substantially linearly reciprocating within the respective cylinder. Also, the drive mechanism includes at least one coupling assembly having a proximal end and a distal end. The linear motion of the piston is converted to rotary motion of the rocking beam. Also, a crankcase housing the rocking beam and housing a first portion of the coupling assembly is included. The machine also includes a working space housing the at least one cylinder, the at least one piston and a second portion of the coupling assembly. An airlock is included between the workspace and the crankcase and a seal is included for sealing the workspace from the airlock and crankcase. A burner and burner control system is also included for heating the machine and controlling ignition and combustion in the burner.
