Title: Piezoelectric type acceleration sensor
Inventor: TAKAHASHI SHIGEMI
IPC: G01P15/09
Filed: 1987-11-06
Abstract: PURPOSE:To obtain stable output even at low acceleration, by pressing a vibration plate by a fixing part so as to increase the radius of curvature of said plate and fixing the same to a pedestal in such a state that spring force is stored. CONSTITUTION:A vibration plate 3 is fixed to a pedestal 2 in such a state that a recessed surface 3c having a piezoelectric film 5 is turned toward a pedestal 2 and pressed by a fixing part 6 so as to make the radius of curvature of the vibration plate larger than a usual one. When the film 5 receives external force (vibration), said film 5 generates not only the (deformation) strain proportional to the acceleration of said force but also charge. When the vibration plate 3 and the film 5 are laminated and unified by an adhesive, if the 'deformation rigidity' of the vibration plate 3 is taken largely so as to neglect the 'deformation rigidity' of the film 5, the deformation of a detection part 1 by vibration acceleration becomes dependent on the deformation of the vibration plate 3 and the characteristic of the film 5 is not damaged by deformation and the generation characteristic thereof is excellent in stability.

Abstract: PURPOSE:To attain PCM transmission with a high S/N and a wide transmission frequency band at a low transmission bit rate, by discriminating a substantial highest frequency of the primary component contained in an analog original signal and producing the transmission data with said discriminating information to transmit this data. CONSTITUTION:The analog signal is converted into the digital data of 14 bits by an A/D converter 2 and applied to the 1st and 2nd data converters 3 and 4 as well as to a frequency discriminator 5. Both converters 3 and 4 use the comprementary bit numbers 7 and 14 and sample frequencies fS and fS/2 to perform the conversion of data so as to obtain the same total number of bits after conversion for each data block between both converters 3 and 4. A frequency discriminator 5 discriminates a high or low level according to whether the substantial highest frequency of the primary component contained in an analog original signal is higher than fS/4 or not. If a high level is decided, a selector 6 is switched to transmit the output of the converter 3 to a transmission line through a terminal 7 as the transmission data together with the discriminating information.
