A robotic manipulator device includes a robotic linkage to rotate an insertion axis about a remote center of motion with two degrees of freedom. A driven link supports the insertion axis. Rigid links in a parallelogram arrangement constrain the driven link to move in parallel to a drive link and the insertion axis to rotate about the remote center of motion. A drive unit has an output shaft coupled to the drive link. Rotation of an input shaft causes the output shaft to rotate. The input and output shafts are at a substantial angle. A housing supports the output shaft. A first motor causes the input shaft to rotate the output shaft. A second motor causes the housing to rotate, rotating the output shaft about an axis that is substantially parallel to the input shaft and passes through the remote center of motion.

A bicycle shift operating device is provided with a support structure, a take-up unit and a shift positioning mechanism. The support structure has an inner wire fixing part. The take-up unit includes a rotating body mounted on the support structure to rotate about a first axis, and an inner wire routing pulley mounted on the rotating body to move with the rotating body about the first axis and to rotate independently of the rotating body about a second axis that is offset from the first axis of the rotating body. The shift positioning mechanism is operatively coupled to the take-up unit to selectively hold the take-up unit in one of a plurality of shift positions.

A connecting rod includes a rod main body, a small end located at one end of the rod main body and a big end located at another end of the rod main body, the big end including a curved section which is curved so as to become narrower toward the rod main body. The big end is formed of a metal material whose composition is different from that of the rod main body, and is bonded to the rod main body. A joint between the big end and the rod main body is located closer to the small end than is an end of the curved section facing the rod main body.

An operational control for use with a ventilation, heating, or air conditioning unit of a vehicle, that can be actuated by a turn knob comprises: a guide member for being attached to and manipulated by a turn knob, the guide member defining a guiding groove; an adjusting lever for actuating a Bowden cable to which the adjusting lever is linked, the adjusting lever being mounted adjacent the guide member to pivot; a guide pin attached to the adjusting lever for extending into the guiding groove for cooperating with the guiding groove to cause the adjusting lever to pivot when the guide member is manipulated. The adjusting lever is made of a material that can be welded to steel and the guide pin is a weld-on steel ball welded to the adjusting lever.

Herein disclosed is a shift fork lubricating system for use in a transmission of the type in which shift forks (4.sub.1, 4.sub.3) have their bearing portions (10.sub.1, 10.sub.3) slidably fitted and supported on a shift fork shaft (2) and their forked pawl portions (6.sub.1, 6.sub.3) formed at their leading ends for engagement with circumferential grooves (8.sub.1, 8.sub.2) of shift gears (7.sub.1, 7.sub.3) so that the shift gears (7.sub.1, 7.sub.3) are shifted by the sliding controls of the shift forks (4.sub.1, 4.sub.3). The bearing portions (10.sub.1, 10.sub.3) of the shift forks (4.sub.1, 4.sub.3) have their inner circumferences formed at their center areas with annular oil grooves (16.sub.1, 16.sub.3), respectively, which are axially elongated and always in communication with oil ports (14.sub.1, 14.sub.3) opened to the outer circumference of the shift fork shaft (2). The shift forks (4.sub.1, 4.sub. 3) have their inner circumferences formed at both the sides of the annular oil grooves (16.sub.1, 16.sub.3) with pairs of sliding faces (17.sub.1, 17.sub.3 ; 18.sub.1, 18.sub.3) which have a substantially equal axial length and which are made slidable on the shift fork shaft (2). The shift forks (4.sub.1, 4.sub.3) are further formed therein with oil passages (15.sub.1, 15.sub.3) which are opened into the forked pawl portions (6.sub.1, 6.sub.3) thereof and which communicate with the annular oil grooves (16.sub.1, 16.sub.3).
摘要:
A shift mechanism in a manual transmission which may reduce an inertial revolution of a counter shaft system by applying to it a dragging resistance or a frictional force before reverse gears are meshed with each other during a reverse shifting operation to prevent a gear buzzing or a body shock, and may permit the reverse shifting operation to be smoothly carried out by releasing the dragging resistance from the counter shaft system upon completion of the reverse shifting operation.

The insert molding device provides a lead groove communicating with a clearance between a cavity and an inserted workpiece in a mold used for molding a plastic coating on part of the workpiece so that excess molten plastic enters the lead groove. The resulting casting fin formed in the lead groove can be easily removed with an automatic machine, thereby reducing the cost of the final product.
摘要:
A control lever assembly for actuating a control cable, particularly a cable of the type capable of transmitting compressive forces as well as tensile forces, known as a push-pull cable. The assembly has a lever journalled for rotation relative to a body thereof, and a core anchoring structure adapted to rotate with the lever and to be subjected to relative lateral movement during such rotation. The core anchoring means anchors one end of a core of the control cable, and a sheath retaining means retains a portion of a sheath of the cable to restrict axial movement of the sheath following actuation of the cable. A connecting structure, which is structurally independent of the control cable, cooperates with the sheath retaining structure and the core anchoring structure to swivel the sheath retaining structure in response to rotation of the core anchoring structure. Thus, the sheath retaining structure swivels to accommodate the lateral movement of the core anchoring structure to maintain approximate alignment of the sheath with the core so as to reduce a tendency of the core to buckle under compressive loads.

A solar generator includes a chamber in the form of a half tee-pee having a chimney-like outlet at an upper end thereof. An air turbine is mounted within the outlet and is coupled to an electric generator. Air inlet tubes are provided at the base of the structure. As air within the chamber is heated by the sun, it rises and passes, at an increased velocity due to the Venturi effect, through the turbine causing the blades thereof to turn.
