Abstract: A cable tie mounting tool comprises an upstream jaw and a downstream jaw having concave guidance path portions for the strap of a cable tie, a placing mechanism configured to place a cable tie portion along the common concave guidance path by pushing it strap-end-first along the common concave guidance path starting at the upstream end of the upstream jaw and pushing it in downstream direction, an insertion mechanism for feeding the cable tie strap end of the placed cable tie through the head of the placed cable tie, and a tightening mechanism for tightening the cable tie and possibly cutting it. Also provided is a length adjustment mechanism for adjusting the length of the common concave guidance path.

Abstract: A starter includes a motor configured with a direct current motor. The direct current motor has a brush and a commutator. The brush is a sintered material formed of graphite and a copper powder. The commutator is formed of either copper or a copper alloy that has a copper content of 99% or more. A surface of is a sliding portion of the commutator which has sliding movement with the brush is provided with a graphite cover-layer that contains graphite as a main component. The graphite cover-layer contains a hard compound which has a Vickers hardness higher than 10 GPa and a metal sulfide solid lubricant.

Abstract: An engine operated machine system includes an engine, a working machine driven by the engine, and a waste-heat recovery unit for recovering the waste heat of the engine, each being accommodated in a box-shaped case. The case is provided with a partition wall which partitions the inside of the case into working-machine accommodating and electrical-equipment accommodating chambers, and which has a draft bore connecting the working-machine accommodating chamber to the electrical-equipment accommodating chamber.

Abstract: A plurality of sun-ray collecting units connected to one another by parallel links and arranged in rows on first turning axes are supported on a pair of turning frames that can be turned about the first turning axes. Each of a pair of push-pull cables 54 is connected at one end thereof to a cable driving device and at the other end to one of the sun-ray collecting units which are supported in plurality on each of the turning frames. Thus, a space for placement of a sun-ray tracking system can be relatively reduced in size and the turning angle of each of the sun-ray collecting units about the first turning axis can be relatively increased. The sun-ray collecting units can be turned about the second turning axes in a simple structure using a single drive source.

Abstract: A load retainer assembly includes a pair of lower and upper plates pivotably mounted on a main shaft, and an inverting mechanism provided between the lower and upper plates that, as the lower plate is driven to pivot, causes the upper plate to pivot in the opposite direction to the pivoting direction of the lower plate. The load retainer assembly further includes a first retaining member for interconnecting distal end portions of a pair of links pivotably connected to one end of the lower plate and one end of the upper plate, respectively, and a second retaining member for interconnecting distal end portions of another pair of links pivotably connected to the other end of the lower plate and the other end of the upper plate, respectively. A suction pad is attached to each of the retaining members to retain a load by suction.

Abstract: A plurality of blade shafts spline-connected to bosses of a plurality of propeller blades are rotatably carried on a propeller boss parallel to the axis of the boss, the propeller blades being rotated so as to increase the propeller-diameter D according to an increase in the centrifugal force, and all the blade shafts are mutually connected through a synchronizer including cranks integrally continuously provided on the blade shafts and a single common synchronizing ring. With this arrangement, it is possible to always equally control opening angles of all the propeller blades despite any partial conditional change.

Abstract: A sleeve 18 spline-fitted in an outer periphery of a propeller shaft 4 is connected to a propeller boss 12 for surrounding the outer periphery of the sleeve by a damper rubber 20 interposed in superposed relation therebetween, and in a recess formed in the outer periphery of the propeller boss 12 so that a bottom surface thereof comes near the outer periphery of the damper rubber 20, propeller blades are rotatably supported on a blade shaft 33 parallel to the propeller shaft 4. With this arrangement, it is possible to provide a compact variable propeller for a boat which can be mounted on a relatively short propeller shaft and which is provided with a torque limiting device.
