    • PROBLEM TO BE SOLVED: To provide a protective mechanism and method for a positioning device, capable of positively operating a protective circuit by detecting that wire break occurs in a sensor cable or a piezoelectric actuator driving cable during the operation of a shaft not connected with a jogging stage (a piezoelectric actuator) or a positioning function. SOLUTION: This positioning device for jogging stage, which applies a driving voltage (a) corresponding to a command value to a piezoelectric actuator for driving, is provided with a monitoring means which monitors a correlation between the driving voltage of the piezoelectric actuator and a detected value (b) of a positioning means of the jogging stage. It is judged as abnormal if the monitoring result of the monitoring means is out of a prescribed range. COPYRIGHT: (C)2004,JPO

    • PROBLEM TO BE SOLVED: To provide a system for accurately and economically monitoring a rupture of a tension material used in a concrete structure over a long period of time.
      SOLUTION: The monitoring system includes a plurality of measuring units and main processors. The measuring unit includes a sensor for detecting an elastic wave, a memory for storing data detected by the sensor, and a controller for transmitting information that the sensor detects the elastic wave exceeding a reference level to the main processor and transmitting the stored data in response to a command from the main processor. The main processor commands each measuring unit to transmit the data stored in the memory after receiving the information from the measuring unit, and analyzes the data transmitted from each measuring unit.

    • PROBLEM TO BE SOLVED: To provide a piezoelectric transformer which can carry out a highly efficient step-up operations, even if an input voltage has waveform distortion. SOLUTION: In a control circuit which generates an AC high voltage for driving a cold cathode tube 2, a notch filter 9 whose center frequency f0 is set at the third overtone of a drive frequency fd of a piezoelectric transformer 1 is provided in a line, via which an input voltage Vi is applied to the piezoelectric transformer 1. Distortion, having a frequency component of the third overtone superposed upon the input voltage Vi, is eliminated by the notch filter. This control circuit drives a Rosen-type laminated piezoelectric transformer by λ mode, by a half-bridge type drive circuit 6.
