Abstract: PROBLEM TO BE SOLVED: To provide an antenna damage detector high in detection accuracy without requiring adjustment and capable of being simply and inexpensively constituted by supplying a DC current from the detector to an antenna through a photocoupler and monitoring on/off of the DC current depending on an output of the photocoupler. SOLUTION: A helical antenna is adopted for an antenna 2, and a main signal line 1 and a DC power supply 3 of the detector are connected to an end of a conductor tube to which an antenna conductor is connected. The DC power supply 3 is connected to the main signal line 1 via a λ/4 line 6 through a current limit resistor 4, and a photodiode of a photocoupler 5 to supply a DC current to the antenna conductor.

Title: Temperature detector and suspended spore removing apparatus using the detector
Inventor: TAKAHASHI SHINPEI
IPC: G01K1/14
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous operation even in a high temp. atmosphere. SOLUTION: A suspended spore removing apparatus has function incinerating spores contained in air by heating elements 21. A lower thermostat 51 is arranged on the suction side of a heating elements 21 low in temp. and an upper thermostat 52 is arranged on the exhaust side of the heating elements 21 so as to provide a predetermined distance. Air is sucked from a suction port by a natural convection and passed through the ducts 21a of the heating elements 21 to be discharged from an upper exhaust port 33. Since the lower thermostat 51 properly detects the temp. of the heating elements 21 even in the case of use in a high temp. atmosphere, the heating elements are not operated at a time of usual use.  For example, in an abnormal state in which the exhaust port 33 is closed and the flow of air is obstructed, the lower thermostat 51 detects the head of heated air to cut off a power supply. The upper thermostat 52 is operated as an emergency one when the lower thermostat 51 gets out of order.
