摘要:
In a piezo-electric motor with alternately electrically actuated clamping piezo packs arranged between a reference part and a drive part and with two stepping piezo packs arranged in an opposite sense and assigned to each clamping piezo pack or to one clamping piezo pack or a support structure, the stepping piezo stacks are connected via quasi-pivotal joint structures to a foot at locations which are spaced from each other in the longitudinal direction of the clamping piezo pack and from the drive part.

摘要:
A magnetic recording medium comprises a magnetically soft underlayer having a plurality of cavities in a surface thereof, and a magnetic recording material in the cavities, wherein a surface of the magnetic recording material in the cavities is substantially coplanar with the surface of the soft underlayer. A recording system that includes the recording medium is also included.
摘要:
A key for a keyboard consisting of a base part (1) with a recess (7), an intermediate part (2), a key head (3) and an elastic return part (4). The cylindrical intermediate part (2) is arranged between the bottom part (14) of the key head (3) and the recess (7), with the intermediate part (2) moving into the recess (7) when the key head (3) is pressed. The intermediate part (2) is in a screw-like engagement with the bottom part (14) of the key head (3) and with the recess (7) in each case, with the one engagement running in the opposite direction to the other engagement.

The invention calls for a pipe with perforated walls to be laid on, in or under the waterproofing, such as located on and under waste dumps, to be monitored and if necessary repaired, the monitoring and repair operations being undertaken from this pipe.
摘要:
A method for manufacturing multi-dimensionally curved guide rails having tubular cross-sections for passenger and material transportation systems, in which a hose-like plastic tube of any tubular cross-section is bent according to requirements and subsequently filled with a filling compound to stabilize the shape.
摘要:
A robot arm consisting of an upper arm link and a lower arm link which are interconnected by a uniaxial joint. The upper arm link is connected with a structure via a universal joint. In order to attain a weight balance, a toggle lever is placed on the upper arm link, on whose one lever arm an upwardly directed equalizing force acts and whose other lever arm is connected to the lower arm link. If both arm links are in alignment with one another, then the point of application of force on the one lever arm has its greatest distance to the universal joint. If, on the other hand, the lower arm link is swung out of its alignment with the upper arm link, then the distance between the point of application of force and the universal joint is decreased.
摘要:
A cycloid gear is provided which comprises a pair of eccentric discs which are attached to a drive shaft and which carry curved discs thereon having outer peripheries of cyclodic curved shape which roll off along a plurality of rollers that engage said outer peripheries, the pair of curved discs having bore holes extending therethrough in overlapping relation to one another respectively to define an effective axially directed opening through each pair of overlapping bore holes, there being a plurality of axially directed bolts which pass through said effective axially directed openings and which are connected to an output shaft to drive the output shaft as the curved discs rotate with rotation of the drive shaft and eccentric discs. Each bolt carries a resilient roller whose unstressed outside diameter is greater than the predetermined minimum dimension of the effective axially directed opening with which said bolt is associated, whereby said rollers transmit the rotational movement of the curved discs to the output shaft without any clearance and preload the gear.
