Title: Object detection method and its unit
Inventor: FUJITA HIDEO
IPC: G01B7/06
Filed: 1979-02-28
Abstract: PURPOSE: To make it possible to detect fluid, powder, etc., by detecting whether an object exists in a vessel or not by change of the resonance characteristic through a piezo-electric element provided on the vessel bottom.  
     CONSTITUTION: Piezo-electric assembly 12 formed by piezo-lectric porcelain 12a, etc., is installed on the bottom of vessel 10. Meanwhile, porcelain 12a, etc., form an oscillator circuit together with a prescribed resistance, etc., and for no load of assembly 12, the oscillator circuit oscillates with the resonance frequency peculiar to porcelain 12a, and indication unit IND is lit through transistor Tr, etc., by the peak detection output outputted from amplifier A. Consequently, when an object  exists in vessel 10 and the impedance of porcelain 12a is changed due to the load  pressure applied to assembly 12, resonance of the oscillator circuit stops to extinguish unit IND. By this constitution, existence of fluid, powder, etc., can be detected surely.
