Title: Energy confinement-type piezoelectric vibrating gyroscope
Inventor: ABE HIROSHI
IPC: G01C19/5698
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To test whether a piezoelectric vibrating gyro is operated correctly or not without applying a rotation to a piezoelectric plate, by installing an auxiliary electrode, applying a driving voltage to the auxiliary electrode in a state that a rotation is not applied, and generating a vibration in Y-direction. SOLUTION: The auxiliary electrode 21 is installed. In a state that a rotation is not applied to a piezoelectric vibrator 1 so as to be a standstill, a driving voltage is supplied to a first electrode 11, and it is applied to the auxiliary electrode 21. Then, a driving electric field is applied across the auxiliary electrode 21 and a second electrode 12 and a third electrode 13, and a piezoelectric plate 10 is excited nearly in the Y-direction. As a result, a vibration, in the Y-direction, which is equivalent to that at a time when a rotation is applied to the piezoelectric plate is generated when the piezoelectric vibrator is driven in the X-direction. Output signals according to the vibration in the Y-direction are obtained from the second and third electrodes 12, 13.  On the basis of the output signals, whether piezoelectric vibrating gyro, particularly a detection circuit connected to the piezoelectric vibrator 1, is normal or not can be judged. That is to say, the application of the driving voltage is changed overt to the auxiliary electrode 21, and the piezoelectric vibrating gyro can be tested.

Abstract: PURPOSE:To achieve a higher warning and evocation capacity of a load power display device, by providing the display device with an AC-DC converting section and a driving circuit section for producing an intermittently driving voltage waveform to let a liquid crystal display element make a flash display. CONSTITUTION:An electric field detecting section 1 detects an electric appliance or a conductor being loaded using a conventional load power display device and conventional one or two current collection plates 11 and 12 and outputs are sent to an AC-DC converting section 2, which rectifies an output of the detecting section 1 to be converted into a DC voltage required for operating a driving circuit section 3. The driving circuit section 3 outputs an output of the AC-DC converting section 2 as intermittently driving voltage waveform to indicate a display pattern of a liquid crystal display element 4 and applies it into the liquid crystal display element 4. An output of such an intermittently driving voltage waveform causes the liquid crystal display element 4 to make a flash display. By selecting time distribution and cycle for outputting and posing, the load power display device 10 can perform a flash display at an easily visible interval thereby making it very effective in enhancing warning and evocation capacity.
