The TBM shield anti-side-rolling walking support device not only solves the constructionproblem of the shield body of the cylindrical TBM tunneling machine easily rolling to the both sides when slipping and walking in the gate tunnel, but also bears part of the front shield load and reduces the pressure of the front shield on the slide rail.

PROBLEM TO BE SOLVED: To provide a memory card connector capable of reliably preventing, with a simple structure, the insertion of a memory card in an improper posture, without carrying out any work on a case.SOLUTION: A leaf spring piece supported in a cantilevered manner is formed integrally with a cover. An erroneous insertion prevention plate on at least a free-end side of the leaf spring piece is inclined downward with respect to the cover such that a rear lateral surface of the erroneous insertion prevention plate faces the inner side of a card housing part in a manner perpendicular to an inserting direction of a memory card and crosses a movement track of an inclined surface of the memory card inserted in the card housing part. If the memory card is inserted in a regular posture, the inclined surface abuts on a lower portion of the rear lateral surface and pushes up the erroneous insertion prevention plate, but if the memory card is inserted in an improper posture, a flat surface abuts on the rear lateral surface, thus causing the erroneous insertion prevention plate to restrict the insertion of the memory card.

The invention relates to a piezoelectric transducer, a method for preparing the piezoelectric transducer and electronic equipment. A piezoelectric transducer, comprising a support structure and a piezoelectric diaphragm arranged on the support structure; the piezoelectric diaphragm includes a beam, and one end of the beam in a first direction is supported by the support structure , the other end is a free end; the piezoelectric diaphragm includes a first electrode layer and a piezoelectric material layer sequentially stacked on the support structure; wherein, the area of ​​the piezoelectric material layer at the free end is smaller than that of the first electrode layer The area of ​​an electrode layer.
