Abstract

PURPOSE: To simplify the structure without requiring power for temperature detector by receiving microwave delivered from a magnetron with an antenna of heat- sensitive needle and inducing voltage with conductive shaft of antenna and a conductive wire.
CONSTITUTION: When a temperature detector 5 enters the microwave electric field, an antenna 7 and a protective container 6 become an antenna unit, so that a microwave voltage is induced between the root 7' of the antenna 7 and a case 18, consequently, due to the voltage of the microwave of a conductive shaft 7a, inducing a microwave voltage V1 on a conductive wire 19. This part becomes an electric energy generating circuit part 12. A series circuit of wave detecting diode 20 and another series circuit of protective zener diode 21 are connected in parallel to this conductive wire 19, and a through-type capacitor 22 is inserted in series thereto, thereby composing a wave detecting circuit 13. A power generating circuit 11 is constituted with circuits 12, 13 and a constant voltage generating circuit 14 so as to deliver a constant voltage V4, which is then used as the driving power for the heat-sensitive element 15 and transmitter 17
