Title: Method and device for detecting temperature
IPC: G01K7/24
Filed: 1992-03-23
Abstract: PURPOSE:To detect the temperature of an object by applying an AC voltage across a thermister, the resistance of which changes in accordance with its ambient temperature, and detecting a voltage change caused by the resistance change of the thermister. CONSTITUTION:A thermister RT, the resistance of which largely changes in accordance with the variation of its ambient temperature, is connected between the common contacts of change-over switches 1 and 2. The switches 1 and 2 are respectively connected to their (+) and (-) side contacts by means of output Q1 and Q2 from a transmitter 4 and an electric current flows in the direction shown by the solid line from a DC power source E through the (+) side contact of the switch 1, thermister RT, an< (-) side contact of the switch 2. When the outputs Q1 and Q2 of the transmitter change, the connecting directions of the switches 1 and 2 change and the electric current flows in the direction shown by the broken line. Then the output of an A/D converter 3 is inputted to a voltage-temperature conversion circuit 5 and the circuit 5 outputs the output after converting the output into temperature data. Therefore, the flowing direction of the electric current flowing through the thermister RT is changed and migration caused by the generation and reduction of metallic ions in an electrode section can be prevented.

Title: Pulse burner
Inventor: INUI ISAO
IPC: F23C15/00
Filed: 1984-04-03
Abstract: PURPOSE:To obtain a pulse burner of low noise without beat noise, by juxtaposing pulse burners into which input power is equally divided to that the sum total of input power is to become a required input power. CONSTITUTION:When the rate of combustion and the pulsating frequency in the primary pulse burner 1 are larger than those in the secondary pulse burner 2, the velocity of combustion waste gas 27 in the part where tail pipes 5 and 6 are connected by a connecting pipe 29 is faster than the velocity of combustion waste gas 28. Part of combustion waste gas 28 joins a connecting flow 30, passing through the connecting pipe 29 by the ejector effect of a faster flow 27. While the degree of negative pressure in combustion chambers 3 and 4 is increased to get into a suction cycle, part of combustion waste gas 28 is sucked again toward the pulse burner 1, passing through the connecting pipe 29. As a result, the rate of mixed gas flowing into the combustion chamber 4 passing through a gas valve 18 and air valve 16 is increased. Thus pulsating frequency is increased, both burners are synchronized with each other, and least noise in both burners during cumbustion can be prevented.
