Abstract

PURPOSE: To reduce mis-information with no fire taken place, by evaporating electrodes on the both surfaces of thin film ferrodielectric substance, making black the electrode surface at infrared ray incoming side, sectioning one of the both electrodes into a plurality of number, and generating the bidirectional sign signal with the sensor in non-contacting manner.
