The invention relates to a compound of formula : 1wherein: R1 represents halogen or a group CF3, R2 represents hydrogen or alkyl or cycloalkyl, R3 is as defined in the description, R4 and R5 represent hydrogen or alkyl, cycloalkyl, aryl or arylalkyl a group 2Medicaments. The resistance element is positioned within the line segment and impresses a predetermined flow resistance on an air flow that extends from the air inlet to the air outlet. In the strain sensor chip mounting structure which is one embodiment of the present application, a strain sensor chip is fixed onto a surface to be measured of the object to be measured via a metallic bonding material. This unique identification of the contents of the files on the client is accomplished by performing a cryptographic hash of the contents of the individual files. Moreover, the latch provides an output to demonstrate that an overload has occurred.
