摘要:
An actuating device (10) actuates a shading system with a string element (44). An unintended detachment of a first partial structure (12) from a second partial structure (13) in the intended use is avoided as much as possible and a detachment of the first partial structure (12) from the second partial structure (13) is possible with low forces for avoiding injuries. The actuating device (10) includes a first coupling element (26, 27) that in the released position does not mesh with a second coupling element (28, 29), and in the locking position, with an interaction of the first coupling element (26, 27) with the second coupling element (28, 29), a detachment of the first partial structure (12) from the second partial structure (13) is prevented because of a positive-locking connection between the first coupling element (26, 27) and the second coupling element (28, 29).

There is disclosed a trash rake system for use in clearing debris from an intake screen of an intake trash rack of a water intake port of a water use facility. The intake screen is configured to collect debris transported by water, for example, a river, to prevent the debris from entering the intake port of the water use facility. The trash rake system includes a track system, a movable support structure, a rack and pinion drive mechanism, and a controller configured to receive signals from an encoder on a drive motor and a proximity sensor system.

A ring gear (82) of a planetary gear speed reducer (80) is fixed to a casing (31) provided with a core metal (31) fixed to a vehicle panel via a rubber damper (92). Therefore, the driving unit can be reduced in size through adoption of a speed reducer (80) formed of gears (82) made of spur gears, and the rubber dumper (92) can suppress low frequency vibrations which are transmitted from the speed reducer (80) to the vehicle panel. Therefore, the vehicle body of the vehicle having a low characteristic frequency is prevented from resonating with the incoming low frequency vibrations to generate noises which are transmitted to the vehicle interior, and which give an occupant an unpleasant feeling.

A linear motion mechanism includes a base, a driving module, a driven module, and a pulling member fixed to the base. The driven module includes a sliding plate slidably mounted on the base and connected to the driving module, a transmission assembly, and a moving stage. The sliding plate has a guide hole, and the moving stage is slidably mounted on the sliding plate and connected to the transmission assembly. An end of the pulling member is fixed to the base, and an other end of the pulling member extends through the guide hole and is connected to the transmission assembly. The sliding plate, when driven by the driving module, is configured for telescopic movement relative to the base, and the pulling member is configured to pull the moving stage along the guide hole by the transmission assembly.

A push-pull chain actuator (1) includes a housing with a chain exit/entry opening (4) and a sprocket (9) arranged to engage a push-pull chain (3). The sprocket (9) causes the polygon effect. The actuator includes a first chain guide part (10a) for guiding said push-pull chain (3) around the sprocket (9) and a second chain guide part (lob) for guiding said push-pull chain (3) at the correct angle between the chain exit/entry opening (4) and the sprocket (9). The second chain guide part (10b) is shaped and dimensioned to counteract the polygon effect. Alternatively, the second chain guide part (10b) can be shaped and dimensioned to reduce chain oscillations caused by the rollers (8c) engaging or disengaging the chain exit/entry opening (4) at the end of the second chain guide part (10b).
摘要:
A drive arrangement for an endoscopic shaft instrument, preferably an instrument which is intended for use in connection with a surgical robot, has a drive arrangement that has an instrument housing (12) on a proximal shaft end. At least one housing shaft (22) is mounted in the instrument housing (12). The shaft is drivingly connected to a traction device which is provided for controlling an instrument head on a distal shaft end. Furthermore, the drive arrangement has a drive unit having at least one drive shaft. The housing shaft (22) can be drivingly connected to said drive shaft. The at least one housing shaft (22) is oriented at an angle to the drive shaft (30) and the drive shaft can be drivingly connected thereto.

摘要:
A driving device is used in an image reading apparatus, and reciprocates a scanning unit for reading an image on an original. The driving device comprises a pull member, a driving pulley which transmits driving force to the pull member, a following pulley which applies tension to the pull member and a pulley holder having a pulley axis which holds the following pulley rotatably. Then, the pulley axis has a lock pawl capable of locking an upper end portion of the following pulley and canceling engagement with the following pulley by being tilted toward a side of an axial center by elastic deformation. Furthermore, the lock pawl is arranged at a side of a tension acting direction from the pull member to the following pulley except the farthest position from the driving pulley among positions in a circumferential direction of the pulley axis. It is possible to attach and detach the following pulley easily at a time of maintenance or the like.
