The transport carriage (1) for the accommodation of a needle board (2) comprises a console (21) that is preferably supported so as to be pivotable about a rotational axis (22). Clamping jaws (24, 25) are provided on the console (21), with the clamping jaws clamping the needle board (2)—preferably in a force-limited manner—between each other and thus holding said needle board in a frictionally engaged manner.

The present invention relates to an integrated drive mechanism of tiny piezoelectric motor- lens piece including a ring-shaped piezoelectric stator, a rotor and a drive power supply. Wherein: an innerscrew is positioned in the ring shape piezoelectric stator, and the rotor including external screw is ring shaped or cylinder shaped and is integrated as a whole with the lens piece; the external screw of the rotor is inosculated with the inner screw of the stator; the rotor is spun into the stator through the inosculated crew thread. The advantages are: a super-thin ring-shaped piezoelectric stator is provided, and the lens piece is driven directly as a part of the rotor; an opposite higher driving force and efficiency are provided; the screw thread transmission is not sensitive to the vibration; the motor can work at a lower voltage because the piezoelectric element on the piezoelectric stator is flaky or has a structure of multiple thin pieces; the device is especially adapted to the automatic focusing of the optical lens in the module of mobile telephones and minitype cameras because the motor and lens drive mechanism have less components, a small size and a low cost.

A sensor unit for measuring a measurement variable in a medium, in particular in an aggressive liquid or gaseous medium, comprises a sensor that is arranged in a sensor capsule and has a sensor region that is arranged on a base body. In order to detect the measurement variable in the sensor region, a measurement opening is provided in the sensor capsule. On a side facing the measurement opening, the sensor region has a measurement surface that is provided with measurement electronics. An electrical supply line is provided on the sensor for the purpose of transmitting a sensor signal that is generated by the measurement electronics. A plated-through hole is provided in the base body. The plated-through hole is used to connect the measurement electronics to the electrical supply line via signals through the base body, on a base side of the sensor that faces away from the measurement opening.

A thermally actuated device, such as an electrical circuit breaker (10) is provided with an ambient temperature compensation thermostat metal member (38) selected so that it bends when subjected to changes in temperature and compensates for ambient temperature effects on a thermostat metal trip arm for a selected current rating. Movement of such thermostat metal member is directly proportional to the flexivity of the material and to the square of the length of the member and indirectly proportional to the thickness of the member. Since packaging constraints make changes in length impractical, compensation members used to provide temperature compensation for different current ratings of the device typically have been made by using members of different thickness. In accordance with the invention, ambient temperature compensation members for a family of devices having a plurality of different current ratings is provided by changing the effective length of respective blank thermal compensation members by stamping selected deformations (48c, 50c) appropriate for each current rating in respective blank compensation members.

The invention aims to provide a synchronous phase-shifting Fizeau interference device capable of performing real-time high-accuracy measurement on the surface appearance of an object. A synchronous phase-shifting technology is combined with a Fizeau interference method, and the technical problems that the traditional interferometer has low stability and low measurement accuracy and cannot measure objects in real time and the like are solved. The synchronous phase-shifting Fizeau interference device capable of measuring in real time comprises an illumination unit, an interference unit and a synchronous phase-shifting unit. Due to the adoption of a coaxial interference light path, a space-bandwidth product of a charge coupled device (CCD) is fully utilized; and compared with an off-axis light path, the coaxial interference light path has a higher spatial resolution; a flat glass plate in the traditional Fizeau interferometer is replaced by a 1 / 4 wave plate, so that object light and reference light have orthogonal polarization directions, and the compactness of the structure of the device is kept under the synchronous phase-shifting; and moreover, four phase-shifting interference patterns can be obtained through single exposure, and the real-time property of measurement is realized on the premise of guaranteeing a high spatial resolution.
